    Researchers have discovered the molecule phosphine in the atmosphere of Venus. The molecule indicates that life may exist in the acidic clouds high above our sister planet. The discovery of phosphine in the Venusian atmosphere could signal a rejuvenated interest in the planet, which has long been ignored in favor of other locales in the solar system. A mystery lurks in the clouds high above the stifling surface of our nearest planetary neighbor, Venus. Researchers have announced they've found traces of phosphine, a molecule potentially generated by living things, in the planet's clouds. Planetary scientists have long speculated that Venus's...

    The researchers report that they were studying the planet's rings, which are collectively called Eta, and discovered that they had an oddly shaped orbit -- not round or even circular. Instead, they describe it as sort of triangular. More study showed that the odd orbit of the rings was due to gravitational pull from Cressida -- one of the planet's moons. The gravitational impact is exaggerated, they note, due to the moon keeping pace with the orbit of the planet. The particles in the ring, on the other hand, move faster than the moon. This results in the moon tugging...

    ... New research shows that Uranus, a chilly, hostile planet with a number of peculiar features, was the victim of a devastating impact during those early years, and it might explain some of the planetís strange personality. Uranus moves much differently than the other planets in our Solar System, spinning on its side in comparison to the rest of the worlds in our neighborhood. Astronomers have often wondered just how this happened, but simulations performed by scientists at Durham Universityís Institute for Computational Cosmology might have finally produced the answer. ďWe ran more than 50 different impact scenarios using a...

    You might be aware of one of Uranusí complexities: It spins on its side, and its moons orbit on that same rotated plane. New evidence strengthens the case that Uranus was smashed in a giant collision, resulting in its sideways orientation to its orbital plane and perhaps explaining some of the planetís other mysteries. A new paper performs a series of simulations on Uranus early in its history, taking note of what an early impact may have done to its rotation rate, atmosphere, and internal structure. The impact could have left a clear signature still visible inside the planet we...

    The collision with Uranus of a massive object twice the size of Earth that caused the planet's unusual spin, from a high-resolution simulation using over ten million particles, coloured by their internal energy. Credit: Jacob Kegerreis/Durham University ___________________________________________________________________________ Uranus was hit by a massive object roughly twice the size of Earth that caused the planet to tilt and could explain its freezing temperatures, according to new research. Astronomers at Durham University, UK, led an international team of experts to investigate how Uranus came to be tilted on its side and what consequences a giant impact would have had on the...

    Although planets surround stars in the galaxy, how they form remains a subject of debate. Despite the wealth of worlds in our own solar system, scientists still aren't certain how planets are built. Currently, two theories are duking it out for the role of champion. The first and most widely accepted, core accretion, works well with the formation of the terrestrial planets but has problems with giant planets such as Uranus. The second, the disk instability method, may account for the creation of giant planets. "What separates the ice giants from the gas giants is their formation history: during...
  • HUBBLE JUST SPOTTED SOMETHING MASSIVE COMING OUT OF URANUS

    Bursts of solar winds caused a huge sparkling region on Uranus, scientists observed this by using Hubble space telescope. Electrons that come from various origins such as solar winds, the planetary ionosphere and moon volcanism, when charged in the form of streams caused this, researchers from the Paris Observatory used the NASA/ESA Hubble Space Telescope to observe this on Uranus. They were able to catch it in powerful magnetic fields and, controlled it into the upper atmosphere, where set off spectacular bursts of light when made interactions with gas particles, such as oxygen or nitrogen.

    The Guardian ^ | Monday, July 20, 2020 | Agence France-Presse
    Scientists have identified 37 volcanic structures on Venus that appear to have been recently active - and probably still are today - painting the picture of a geologically dynamic planet and not a dormant world as long thought. The research focused on ring-like structures called coronae, caused by an upwelling of hot rock from deep within the planet's interior, and provided compelling evidence of widespread recent tectonic and magma activity on Venus's surface, researchers have said. Many scientists had long thought that Venus, lacking the plate tectonics that gradually reshape Earth's surface, was essentially dormant geologically, having been so for...

    What started as a dry run to ensure instruments on NASA's Mercury Surface, Space Environment, Geochemistry and Ranging (MESSENGER) spacecraft worked properly later turned into a 10-year saga that resulted in a chance discovery unrelated to the mission's target planet, Mercury. It's about Venus and its atmosphere. The team reports April 20 in Nature Astronomy that data fortuitously collected by MESSENGER reveals a sudden rise in nitrogen concentrations at about 30 miles above Venus' surface, demonstrating the planet's atmosphere isn't uniformly mixed, as expected. That finding upends an understanding about Venus' atmosphere that has prevailed for decades. The story started...

    For several years, UCLA astronomers have studied GD 362, a peculiarly dirty white dwarf star 165 light-years away in the constellation Hercules. Now they are pretty sure why the atmosphere of this dense, hot but slowly cooling ghost of a once much larger star is so polluted. It ate a planet.

    Radio, IR and optical observations show evolution of plumes and their impact on belts and zones Storm clouds rooted deep in Jupiter's atmosphere are affecting the planet's white zones and colorful belts, creating disturbances in their flow and even changing their color. Thanks to coordinated observations of the planet in January 2017 by six ground-based optical and radio telescopes and NASA's Hubble Space Telescope, a University of California, Berkeley, astronomer and her colleagues have been able to track the effects of these storms -- visible as bright plumes above the planet's ammonia ice clouds -- on the belts in which...

    One of the big questions in solar physics is why the Sun's activity follows a regular cycle of 11 years. Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), an independent German research institute, now present new findings, indicating that the tidal forces of Venus, Earth and Jupiter influence the solar magnetic field, thus governing the solar cycle.

    A study published in the journal Earth and Planetary Science Letters posits that Mars formed in what today is the Asteroid Belt, roughly one and a half times as far from the Sun as its current position, before migrating to its present location. The assumption has generally been that Mars formed near Earth from the same building blocks, but that conjecture raises a big question: why are the two planets so different in composition? Mars contains different, lighter, silicates than Earth, more akin to those found in meteorites. In an attempt to explain why the elements and isotopes on Mars...

    Back in 2006, the Catalina Sky Survey in Arizona noticed that a mysterious body had begun orbiting the Earth. This object had a spectrum that was remarkably similar to the titanium white paint used on Saturn V rocket stages and, indeed, a number of rocket stages are known to orbit the Sun close to Earth. But this was not an object of ours. Instead, 2006 RH120, as it became known, turned out to be a tiny asteroid just a few metres across--a natural satellite like the Moon. It was captured by Earth's gravity in September 2006 and orbited us...

    Long before the Bible's tale of Jonah being swallowed by a whale, a small wannabe star has emerged intact after being engulfed by a neighboring giant star, scientists say. The victim was a brown dwarf, a failed star too small to sustain the nuclear reactions that ignites regular stars. The purpetrator was a red giant, an ancient star that once resembled our Sun but which puffed up to enormous size after its hydrogen fuel was depleted. The red giant has since expelled most of its gas into space and transformed into a dense, Earth-sized star called a white dwarfs. Using...

    Meanwhile, the Doppler discovery of extrasolar planets orbiting very close to their parent stars has raised a different problem. Many of the planets are so close to their stars (<0.1 AU), and so hot, that they cannot be supposed to have formed where we now observe them. By inference, they could have formed at larger distances (several AU) and then migrated inwards. What would cause this inward migration? As with the solar system case, the root cause may be an exchange of angular momentum with material surrounding the planets at their formation. In particular, if the extrasolar planets formed in...

The core isnít as dense as researchers suspected, but determining why that is has proven to be a challenge. ďThis is puzzling,Ē Andrea Isella, co-author of a new study published in Nature, said in a statement. ďIt suggests that something happened that stirred up the core and thatís where the giant impact comes into play.Ē

    Israeli archaeologists have unearthed a rare sarcophagus featuring a slender face and a scarab ring inscribed with the name of an Egyptian pharaoh, Israel's Antiquities Authority said Wednesday. The mystery man whose skeleton was found inside the sarcophagus was most likely a local Canaanite official in the service of ancient Egypt, Israeli archaeologists believe, shining a light on a period when pharaohs governed the region. "This is a really beautiful face, very serene," said Edwin van den Brink, an Egyptologist and archaeologist with Israel's government antiquities authority. "It's very appealing." Van den Brink said archaeologists dug at Tel Shadud, an...
