Solar System:

    This is one of the most unexpected scientific discoveries of the year. To their surprise, British scientists revealed last week They found strong evidence That phosphine – a toxic, rancid gas produced by microorganisms – is present in Venus’ burning, acid-dampened atmosphere. By rights, it simply should not be. “All the geological and photochemical pathways we thought of were too ineffective to produce the phosphine we saw,” said Jane Greaves, an astronomer at Cardiff University. That result leaves scientists with bizarre expectations – the microbial activity of the main source of phosphine on Earth – searing, may occur in acid clouds Friday. The news that there may be bugs in Venus should come as no surprise in the front-page...

    SACRAMENTO (CBS13) — A blind Sacramento man says his new solar panels don’t work and the company closed, so it was time for Call Kurtis to investigate. Jeff Thom and his wife Leslie are among the viewers who contacted Call Kurtis saying solar companies oversold them on the cost savings. “They were totally dishonest with me. They absolutely swindled me out of my money,” Thom said. Thom says the solar system they bought from a now out-of-business solar company did not erase their power bill as promised. In fact, he says the panels on his roof don’t work at all. He says no one wants to touch his panels due to liability. Other viewers have contacted our team over the...
    Members of the public acting as 'citizen scientists' have aided experts developing a new system for forecasting when potentially dangerous solar storms will hit Earth. Physicists from Reading enlisted help to analyse so-called 'coronal mass ejections' (CMEs) — powerful expulsions of charged particles and magnetic field from the Sun. When they reach Earth, in as little as 15 hours, CMEs have the potential to damage electrical equipment — from orbiting satellites to ground-based energy grids. A solar storm in 1859, for example — the 'Carrington Event' — induced such currents in telegraph wires that pylons sparked and operators received electric shocks. Predicting when these storms occur could help governments and companies protect satellites, the power grid and communications infrastructure from...
    (CNN)Exoplanets, or planets outside of our solar system, that contain more carbon than Earth could be made out of diamonds, according to a new study. Data provided by NASA's planet-hunting TESS mission, the Hubble Space Telescope and retired Kepler mission have shown that our galaxy is filled with exoplanets that are very different from the planets in our own solar system. As the NASA Exoplanet Travel Bureau posters created by artists collaborating with planetary scientists point out, these weird and wonderful exoplanets are filled with things that are hard to imagine. Some are so hot that they host oceans of lava with sparkly silicate skies while others orbit two suns like planets from Star Wars. Others are rogue planets with...
    For some planets, diamonds aren’t a rarity — they’re the foundation of existence. New research published late last month in the Planetary Science Journal has found that exoplanets with the right ratio of carbon and oxygen would be made primarily of diamonds and the natural compound silica. “These exoplanets are unlike anything in our solar system,” lead author Harrison Allen-Sutter of Arizona State University’s School of Earth and Space Exploration said in a press release. The discovery comes as scientists, enabled by more and more information from recent space missions, are able to put together the pieces and understand what planets far beyond our Earth look like. While Earth’s diamond content is approximately 0.0001%, researchers now believe that exoplanets...

    IT'S the solar system's hottest planet and is shrouded with clouds of sulphuric acid which would melt any living creature who encountered them. But scientists have claimed the hellish planet of Venus once boasted a massive ocean - which may have been home to alien organisms. 3 A Nasa illustration of how a waterbound Venus might look 3 Venus as it appears now - a hot, desolate world with swirling clouds of sulphuric acid Academics from the French Université Paris-Saclay used computer simulations to predict that Venus once had a thick cloud covering and shallow oceans. The boffins suggested that the planet was extremely hot when it was first formed, but may have cooled down enough for liquid water to exist...
    (Reuters) - Scientists have spotted evidence of potential life on the planet Venus, though they emphasized that more work needs to be done to confirm whether or not life - possibly aerial microbes - exists or whether there is an alternative non-biological explanation for their findings. Here is a look at key facts about the planet Venus, based on information from the U.S. space agency NASA and recent research findings. -- Venus, with a diameter of about 7,500 miles (12,000 km), is slightly smaller than Earth. It is the second planet from the Sun and is Earth's closest planetary neighbor. Venus spins from east to west, the opposite direction from all the other planets in our solar system aside from...
    Here in the solar system, we have an interesting variety of planets, but they are defined by the composition of our sun. Since planets, moons, asteroids and other bodies are formed from what remains after the formation of the sun, their chemistry is thought to be related to our host. But not all stars are made from something like our Sun, which means that in the vast expanses of our galaxy, we can expect to find planets that are different from the offerings in our tiny solar system. For example, carbon-rich stars compared to our Sun – with more carbon than oxygen – may have exoplanets, made primarily of diamonds, with little silica, if conditions are right. Now, in a...
    Posted on September 12, 2020 in Astronomy, Strange Planet, Science “A planetary search is a search for life.” Natalie Patel, Kepler lead scientist at NASA Ames Research Center. Sometimes unlike anything in our solar system, in search of a habitable planet like Earth, something really strange appears. The “extraterrestrial age of the planets” was officially launched in October 1995 by the Nobel Laureate. Michael Meyer W. Didier Kiel Rose Announced the first discovery of a planet outside our solar system, an extraterrestrial planet, a planet orbiting a solar type star in our galaxy. The gaseous Milky Way is similar to Jupiter, which is the largest gas company in our galaxy. Their discovery marked the beginning of a revolution in...
    When you’re living, learning, working and playing from home, you expend not only more human energy, but more electric and gas. That’s why now more than ever is a good time to gain more power at home. According to the California Public Utilities Commission (CPUC), residential electric usage increased 15% to 20% just in the first three weeks of California’s stay-at-home pandemic order, compared to the same period in 2019. With the summer underway and autumn approaching, that number is likely to increase. Additionally, in June, PG&E explained that cooling systems account for more than half of the energy usage in the average home or business. Put into perspective for new-home buyers, the natural increase in energy consumption may not...
    The sun, the center of the solar system, continues to fascinate researchers, and NASA has sent a probe to “touch” the massive star. A new study, however, suggests it may have a long-lost twin. The research, published in The Astrophysical Journal Letters, suggests that traces of the sun’s “temporary binary companion” are seen in the Oort cloud, described by NASA as “the most distant region of our Solar System.” “Previous models have had difficulty producing the expected ratio between scattered disk objects and outer Oort cloud objects,” study lead author Amir Siraj said in a statement. “The binary capture model offers significant improvement and refinement, which is seemingly obvious in retrospect: most Sun-like stars are born with binary companions.”...

    Earth's supply of water didn't arrive with a bang from a comet or asteroid, researchers claim - it was likely here at the time our world first formed. A new study by the Centre de Recherches Petrographiques et Geochimiques, France, examined a meteorite called an enstatite chondrite for signs of hydrogen. Researchers discovered the space rock - composed of material found in the inner solar system - contained sufficient hydrogen to deliver at least three times the amount of water found in the Earth's oceans and probably considerably more. As this rock is made of the same material as the Earth, it suggests that when it formed 4.5 billion years ago it did so with the materials for water already...
    When you look at the stars, what do you think about? That we are not alone? In the immensity of everything around us? The universe is filled with billions of star systems. What exactly is a solar system? Located within galaxies, it is made up of at least one star and a number of objects that travel around it, including planets, dwarf planets, moons, asteroids, comets, and meteoroids. In essence, it is a group of celestial bodies located within the Milky Way. In the center of these bodies is the Sun, which is orbited by eight planets; more than 150 moons; and millions of meteoroids, comets, asteroids, and a handful of dwarf planets (we still feel it for Pluto). The...
    A small, rainbow colored meteorite discovered in Costa Rica last year may be harboring the building blocks of life. The cosmic rock was once connected to washing machine-sized asteroid that fell to the Earth on April 23, 2019, scattering across two villages – La Palmera and Aguas Zarcas. The asteroid was a remnant of the early solar system and the meteorite, called Aguas Zarcas, could be made of complex carbon compounds. Scientists believe it could contain complex organic compounds because it is made of the same dust from the early Milky Way that was found in a separate meteor that exploded over Murchison, Australia in 1969, which was found to have amino acids. However the team hopes to find proteins...
    An unprecedented astronomical discovery took place in 2017: 33 million kilometers from Earth an object was moving towards the inner solar system at incredible speeds. Its trajectory and speed place its origin outside the solar system. This foreign visitor was baptized as Oumuamua, it is the first interstellar comet, that is, the first object to enter our solar system from beyond its limits. Since then, Oumuamua has excited the imaginations of science fans, putting astronomers from around the world to work to elucidate its origin. What puzzles scientists most are its peculiar characteristics. In addition to its speed, which accounts for its distant origin, it has a strange shape, it lacks a tail, and its rotation is chaotic. ...
    But, as in any engine, the fuel is not infinite. Upon reaching senescence, the Sun will run out of its hydrogen reserves, so it will have to start fusing helium atoms in its place. When this happens, such a physical reaction will provide it with more energy, which will cause the Sun to begin to overheat to hundreds of millions of degrees Celsius, and also to expand. Stars are the only thing that heats up before cooling down, giving way to a red giant. The red giants, then, are stars in the throes of death. During its transformation, the Sun will increase in size. So much so that it will reach the orbits of Mercury, Venus, and probably Earth. Our...
    Scientists have captured the first direct image of a solar system that closely resembles our own. The new image is a family portrait of sorts, showing two giant exoplanets orbiting a young, sun-like star, roughly 300 light years away.  The picture was taken using the European Southern Observatory's Very Large Telescope, located in Chile's Atacama Desert. According to a new study in the Astrophysical Journal Letters, the system will help astronomers better understand how our solar system formed and evolved The star, known as TYC 8998-760-1 and located in the Southern constellation of Musca, is only 17 million years old, which researchers called a "very young version of our own sun." Comparatively, the sun is roughly 4.6 billion years old. ...
    Earth is unique among the planets in our solar system. Its particular conditions have given rise to all kinds of life, including millions of species of plants and animals. The planet is incredibly diverse: it has high mountains and deep valleys, humid forests and arid deserts, hot and cold climates. Its 195 countries They house more than 7,500 million people. So is; our home is a world unlike any other. At least for the moment. Earth is the third planet from the sun and has a radius of 6,371 km. It is the fifth largest planet in our solar system, and it is the only known planet that will surely have liquid water on its surface. It is...
    The pages of science fiction books are filled with alien visitors who secretly enter the solar system to spy on humanity as we emerge as a technologically capable race, like in Star Trek. So let’s imagine the emotion we feel when On October 19, 2017, astronomer Robert Weryk saw an object traveling through the solar system. while using the Pan-STARRS telescope at the Haleakalā Observatory in Hawaii. Nicknamed ‘Oumuamua (‘ explorer ‘in Hawaiian), this object is one of the strangest we have come across so far. It is extremely elongated, possibly up to a kilometer long but not more than 167 meters wide, so it appears a kind of space cucumber. It travels so fast that there is no way...
    CAPE CANAVERAL, Fla. — For the first time, a telescope has captured a family portrait of another solar system with not just one, but two planets posing directly for the cameras while orbiting a star like our sun. This baby sun and its two giant gas planets are fairly close by galactic standards at 300 light-years away. The snapshot — released Wednesday — was taken by the European Southern Observatory’s Very Large Telescope in Chile’s Atacama Desert. What makes this group shot so appealing is it’s a “very young version of our own sun,” said Alexander Bohn of the Netherlands’ Leiden University, who led the study. Bohn said he was “extremely excited” about the discovery. “This is the first time...
    A visitor from far space approaches Earth: Comet Neowise, discovered last March, is approaching our planet this week on its long journey through our solar system. Since it approached the Sun in early July, its brightness and long tail have begun to grow and it is already the protagonist of thousands of amazing photographs in the sky of sunrise and sunset (in the northern hemisphere). It is the first comet that we can see with the naked eye in more than a decade and, like almost all astronomical phenomena, has generated a growing fascination. So at BBC Mundo we asked you last week what you wanted to know about Neowise and comets in general, and we interviewed a NASA expert...

    The first ever photo of two exoplanets orbiting a young Sun-like star 309-light years from the Earth has been captured by astronomers using a ground-based telescope.  The European Southern Observatory’s Very Large Telescope in Chile was used to capture the image of the two giant exoplanets orbiting a very young star.  Astronomers say this image of two exoplanets orbiting a star is a snapshot of an environment similar to our Solar System  - but at an earlier stage in its evolution.  The two gas giants are much larger and much further away from their host star than Jupiter or Saturn are in the Solar System, according to researchers. The star is incredibly young at just 17 million years old, emerging...
    But as far as Venus it means, it seems logical is that it could have some moon, for the large amount of matter that circulated around the Solar System during its formation, as well as the rest of the planets in the Solar System. In 2006 researchers Alex Alemi and David StevensonThe California Institute of Technology appealed that there would have been a high probability that at least one cosmic object whose remains made up a satellite had collided with Venus. Scientists thought that, perhaps, over time it would have become too far from the planet to be lost, in the same way that the Moon gradually moves away from Earth. And in fact, Alemi explains that, apparently, ten million...
    You might be able to catch a glimpse of Comet Neowise tonight. Mostly clear skies over the last week have meant that many photographers have already managed to capture a snap of the newly discovered comet. Comet Neowise reached its closest point to the sun on July 3 and is expected to reach its closest point to Earth in just a couple of days time. That means now is the perfect time to try and spot it – but you’ll need to stay up late. Astronomers say you will need to head outside after the sun goes down as it is only visible in the dark. So at the moment that’s after 10pm or, if you’d rather have...
    About 4.6 billion years ago, a giant cloud of dust and gas known as the solar nebula it collapsed in on itself and began to form what would eventually become the Sun and the planets of our solar system. He, our star, is the center of our solar system, whose gravitational pull is so powerful that it keeps numerous planets, dwarf planets (like Pluto), comets, and meteorites orbiting around it. Not surprisingly, it is the largest object in our solar system, accounting for 99.8% of the mass of the solar system. Our sun is a G2V-type dwarf that is in the main sequence phase, the main phase of its evolution. This giant, violent fireball fueled by nuclear reactions provides the...
    Over the last several years there have been forecasts of bright comets coming. In fact, some predictions went way over the top with promises like: “Comet of the Century this Month!” or “Comet Coming Visible in Daylight!” Even this year there have been two false alarms for potential bright comets. Those comets broke up when they got close to the sun. With all these claims of bright comets coming, it’s understandable that when people hear or see them they up they chalk it up to media hype. Who can blame anybody for being cynical? Comet NEOWISE, though, is more than making up for exaggerated forecasts. Without a doubt it is already the brightest comet since Comet Hyakutake in the mid-’90s....
    (CNN) — Stargazers in the Northern Hemisphere should enjoy every opportunity to see the new Comet NEOWISE as it streaks across the evening sky for the rest of July. Once it disappears from view, the comet will not be visible in Earth’s skies for another 6,800 years, according to NASA. While July began with the comet visible low on the horizon in the early morning sky, NEOWISE has now transitioned to become an evening comet, perfectly visible as the skies darken. It’s named after NASA’s Near-Earth Object Wide-field Infrared Survey Explorer, otherwise known as the NEOWISE mission, which discovered it in late March. You may be able to see it with the naked eye, but grab a pair of binoculars...

    (CNN)When NASA's New Horizons spacecraft flew by Pluto five years ago this week, it captured detailed views of the mysterious icy dwarf planet on the edge of our solar system. Since then, data gathered about Pluto and its largest moon, Charon, have been used to gain insight about these planetary bodies 4 billion miles away from Earth. New Horizons launched in January 2006 and reached Pluto in July 2015, flying within 7,800 miles of Pluto's surface. The stunning images shared by New Horizons showed both "Earth-like characteristics" on the surface as well as alien landscapes and geology not seen anywhere else in our solar system. And rather than being a quiet, frozen dwarf planet, data gathered by New Horizons revealed...
    'Planet Nine', a celestial object up to 10 times larger than the Earth, may actually be a grapefruit sized black hole - and a new telescope could help detect it.   Objects 'clumping together' in a strange way beyond the orbit of Neptune have led astronomers to suggest 'something big' is interfering with their orbit.   This could be a massive planet or a 'primordial black hole' that crams the mass of up to 10 Earth sized objects into a grapefruit sized sphere, according to astronomers. Researchers from Harvard University and the Black Hole Initiative believe a new 'wide field' telescope being built in Chile could confirm the true nature of 'Planet Nine'. Known as the Vera C. Rubin Observatory, it will...

    CAPE CANAVERAL, Fla. (AP) — A newly discovered comet is streaking past Earth, providing a stunning nighttime show after buzzing the sun and expanding its tail. Comet Neowise swept within Mercury’s orbit a week ago. Its close proximity to the sun caused dust and gas to burn off its surface and create an even bigger debris tail. Now the comet is headed our way, with closest approach in two weeks. NASA’s Neowise infrared space telescope discovered the comet in March. Scientists involved in the mission said the comet is about 3 miles (5 kilometers) across.

    After years of debate, NASA plans to update its guidelines for how much biological contamination of other worlds will be allowed while the agency explores the Solar System. The new rules would relax some of the agency’s requirements for how to explore the Moon and Mars — two high-profile destinations where NASA hopes to send astronauts in the coming years. For decades, NASA has followed fairly strict rules about how much biological contamination is considered acceptable whenever the agency sends probes — or people — to other planets. It’s a concept known as planetary protection, and it has a legal basis in a treaty signed more than 50 years ago. Called the Outer Space Treaty, it challenges nations to explore...

    By TIM KROHN, Mankato Free Press MANKATO, Minn. (AP) — Thomas Rekstein no longer minds looking at the electric bill for his Great River Insurance business on North Riverfront Drive. “My electric bill used to be $4,500 annually, now it’s down to $1,200 a year.” Rekstein, who had 38 solar panels installed on the roof and awnings of his building, said the investment was well worth it. “It’s been great. I’d recommend it to anyone,” he told the Mankato Free Press. Solar power continues to grow throughout the region and state, helped by federal and state incentives and by desire to lower electric costs and reduce reliance on coal and natural gas.

    A Neptune sized gas giant orbiting a star 180 times younger than the Sun has been discovered by astronomers and it could shed light on the evolution of the Earth. The exoplanet was found in a system 32 light-years away and its host star is only 20 to 30 million years old - compared to the 4.5 billion years our Sun has been around.    Named AU Mic b, NASA scientists say the infant planet is about 30,000 miles wide and was discovered by the Transitioning Exoplanet Survey Satellite (TESS). As the planet is still in its infancy the researcher hope to be able to use the discovery to better understand how planets form in the earliest years of a star...

    NASA has proposed a mission to explore Neptune’s mysterious and “weird” moon Triton, the coldest known object in the solar system. In a statement posted to its website, the space agency said the mission, known as Trident, will have a “three-pronged” approach. The mission will observe the celestial satellite to understand the cause of the mysterious plumes emanating from its surface, further explore the moon, which was only 40 percent observed by Voyager 2, and “understand how that mysterious surface keeps renewing itself.” “Triton is weird, but yet relevantly weird, because of the science we can do there,” said Karl Mitchell, Trident project scientist at JPL, in a statement. “We know the surface has all these features we’ve never...

Experts from the Max Planck Institute for Solar System Research in Göttingen, Germany, led an international team of astronomers in the discovery of the exoplanet-star-pair. Exoplanet KOI-456.04 is less than twice the size of Earth, but orbits a sun-like star, explains the Max Planck Institute, in a statement. The star is just over 3,000 light-years from the solar system. A light-year, which measures distance in space, equals about 6 trillion miles. “KOI-456.04 sits in a region of the stellar habitable zone – the distance range around a star admitting liquid surface water on an Earth-like planet – that is...
