Scientists have found evidence that a planet orbiting a distant star may have lost its atmosphere but gained a second one through volcanic activity.

Researchers are taking scientific inspiration from an unlikely source: the biblical tale of Noah's Ark. Rather than two of every animal, however, his solar-powered ark on the moon would store cryogenically frozen seed, spore, sperm and egg samples from 6.7 million Earth species. The proposed structure would be built within the moon's enormous, underground lava tubes, which have been untouched for billions of years.

Electrons arriving from the Sun are propelled by electrical energy generated as high as 30,000 kilometers above Earth, ultimately creating the dazzling displays of the northern and southern lights.

What is the origin of black holes and how is that question connected with another mystery, the nature of dark matter? Dark matter comprises the majority of matter in the Universe, but its nature remains unknown.

In the new study, researchers analyzed the composition of solar energetic particles heading towards Earth, and found they had the same 'fingerprint' as plasma located low in the Sun's corona, close to the middle region of the Sun's atmosphere, the chromosphere.

After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way. The object has settled near a family of captured ancient asteroids, called Trojans, that are orbiting the Sun alongside Jupiter. This is the first time a comet-like object has been spotted near the Trojan population.

Volcanic rock samples collected during NASA's Apollo missions bear the isotopic signature of key events in the early evolution of the Moon, a new analysis found. Those events include the formation of the Moon's iron core, as well as the crystallization of the lunar magma ocean -- the sea of molten rock thought to have covered the Moon for around 100 million years after the it formed.

NASA's Parker Solar Probe captured stunning views of Venus during its close flyby of the planet in July 2020. For more insight, the WISPR team planned a set of similar observations of the Venusian nightside during Parker Solar Probe's latest Venus flyby on Feb. 20, 2021. Mission team scientists expect to receive and process that data for analysis by the end of April.

From aboard the Juno spacecraft, an instrument observing auroras serendipitously spotted a bright flash above Jupiter's clouds last spring. The Ultraviolet Spectrograph (UVS) team studied the data and determined that they had captured a bolide, an extremely bright meteoroid explosion in the gas giant's upper atmosphere.

An international research team has developed a new method for directly imaging smaller planets in the habitable zone of a neighboring star system. This opens up new possibilities in the search for extraterrestrial life.

A scientist has updated Mars chronology models to find that terrains shaped by ancient water activity on the planet's surface may be hundreds of millions of years older than previously thought. This new chronology for Mars, based on the latest dynamical models for the formation and evolution of the solar system, is particularly significant as the days count down until NASA's Mars 2020 Perseverance rover lands on the Red Planet on February 18, 2021.

Astronomers have confirmed that a faint object discovered in 2018 and nicknamed 'Farfarout' is indeed the most distant object yet found in our Solar System. The object has just received its designation from the International Astronomical Union.

A study of a giant impact crater on Venus suggests that its lithosphere was too thick to have had Earth-like plate tectonics, at least for much of the past billion years.

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.
