The discovery of glowing hydrogen gas on Io, a moon of Jupiter, was made using the Hubble Space Telescope. The findings indicate that hydrogen may be concentrated at the poles in the form of hydrogen sulfide frost, which could be broken up into constituent hydrogen and sulfur atoms with glow.
The CU instrument package will study Saturn's spectacular ring system, moons and atmospheric gases. It will analyze the atmosphere of Titan, a moon with conditions similar to early Earth.
A team of researchers estimated that the moon formed in a year or less after a massive collision between Earth and a rogue 'protoplanet'. The study, published in Nature, suggests that only about half of the debris from the collision coalesced into the moon, with the rest falling back to Earth.
A recent meteorite study has provided insights into Mars' formation by analyzing volatile elements in Martian meteorites. The findings indicate that the planet experienced at least two fractionation events, which allowed all elements to remain and record past events.
Researchers outline requirements for habitable moons, including stable orbit and atmosphere retention. Moons in the right position and size could support life on planets like Jupiter's Europa.
Researchers analyzed sediment layers deposited by tides to study the moon's retreat from Earth. The study found that a day on Earth was approximately 18 hours long 900 million years ago, with the moon moving away at a constant rate. The analysis also revealed changes in tidal patterns over time.
