Astronomers revisited and comprehensively reinterpreted the radio telescope observations underlying a widely reported 2019 claim that phosphine gas was present in the atmosphere of Venus. In a paper accepted to the Astrophysical Journal, they report that sulfur dioxide, a common gas in the atmosphere of Venus, is likely what was detected instead of phosphine.

Using a combination of telescopes, including the Very Large Telescope of the European Southern Observatory (ESO's VLT), astronomers have revealed a system consisting of six exoplanets, five of which are locked in a rare rhythm around their central star. The researchers believe the system could provide important clues about how planets, including those in the Solar System, form and evolve.

Astronomers have detected the first Jupiter-like planet without clouds or haze in its observable atmosphere.

Scientists have just shown that the influence of Saturn's satellites can explain the tilt of the rotation axis of the gas giant. Their work also predicts that the tilt will increase even further over the next few billion years.

Far below the gaseous atmospheric shroud on Saturn's largest moon, Titan, lies Kraken Mare, a sea of liquid methane. Astronomers have estimated that sea to be at least 1,000-feet deep near its center - enough room for a potential robotic submarine to explore.

Scientists show evidence that nitrogen acquired during Earth's formation came from both the inner and outer regions of the protoplanetary disk. The study has implications for signs of potential habitability of exoplanets.

Scientists develop theoretical models to predict the presence of clathrate hydrates outside Earth, shedding light on the evolution of other atmospheres.

Astronomers discover that the core mass of exoplanet WASP-107b is much lower than previously thought possible for a gas-giant planet.

Using high-precision brightness measurements from NASA's TESS space telescope, astronomers found that the nearby brown dwarf Luhman 16B's atmosphere is dominated by high-speed, global winds akin to Earth's jet stream system. This global circulation determines how clouds are distributed in the brown dwarf's atmosphere, giving it a striped appearance.

Astronomers using NASA's Hubble Space Telescope watched a mysterious dark vortex on Neptune abruptly steer away from a likely death on the giant blue planet.

By monitoring the cosmos with a radio telescope array, an international team of scientists has detected radio bursts emanating from the constellation Boötes. The signal could be the first radio emission collected from a planet beyond our solar system.

A new device promises insight into how the building blocks of life form in outer space. It mimics how molecules come together in the freezing darkness of interstellar space.

Researchers have discovered a new superhighway network to travel through the Solar System much faster than was previously possible. Such routes can drive comets and asteroids near Jupiter to Neptune's distance in under a decade and to 100 astronomical units in less than a century. They could be used to send spacecraft to the far reaches of our planetary system relatively fast, and to monitor and understand near-Earth objects that might collide with our planet.

Engineers have demonstrated how a series of lunar images can be used to infer the direction that a spacecraft is moving. This technique, sometimes called visual odometry, allows navigation information to be gathered even when a good map isn't available. The goal is to allow spacecraft to more accurately target and land at a specific location on the moon without requiring a complete map of its surface.

Astronomers have taken a step towards understanding how the Moon might have formed out of a giant collision between the early Earth and another massive object 4.5 billion years ago.

     (via sciencedaily.com) 

An international team of scientists has identified a problem with the growing interest in extractable resources on the moon: there aren't enough of them to go around. With no international policies or agreements to decide 'who gets what from where,' scientists believe tensions, overcrowding, and quick exhaustion of resources to be one possible future for moon mining projects.

The first mining experiments conducted in space could pave the way for new technologies to help humans explore and establish settlements on distant worlds, a study suggests.

The high-pressure mineral Donwilhelmsite, recently discovered in the lunar meteorite Oued Awlitis 001 from Apollo missions, is important for understanding the inner structure of Earth.

The mineral olivine, thought to be a major component inside all planetary bodies, holds secrets about the early formation of the solar system, and a team of researchers has a new way to study it remotely.

New work reveals the likely original locations of Saturn and Jupiter. These findings refine our understanding of the forces that determined our Solar System's unusual architecture, including the ejection of an additional planet between Saturn and Uranus, ensuring that only small, rocky planets, like Earth, formed inward of Jupiter.
