Interstellar comets like 3I/ATLAS could serve as seeds for giant planet formation, potentially explaining how massive planets form around distant stars, according to BBC and Pfalzner’s research.

For most of its journey 3I/ATLAS has been frozen solid, but the warming rays of our Sun are enough to unfreeze some of its gases such as carbon dioxide, generating a faint cometary tail. For a period ...

Manhattan-sized comet 3I/ATLAS — which scientists suspect could have extraterrestrial origins — will reach its closest ...

About 50 light-years from Earth, a gas giant about half the mass of Jupiter orbits a sunlike star. The discovery of Pegasi 51 b ushered in a new era of exoplanet research.

Mercury reaches its greatest eastern elongation on October 29, appearing farthest from the Sun in the southwestern sky, offering a brief window for observation after sunset.

Tests on olivine hint that water-rich exoplanets could generate H2O internally, possibly explaining ocean worlds and even some of Earth’s early water.

Astronomers have identified 2025 SC79, a new asteroid with a remarkably fast 128-day orbit, placing it among the ...
