Peering through a cosmic keyhole at distant baby star, astronomers may have opened a new window on the deep past of our own solar system. Weighing in at 0.6 solar mass, HOPS-315 should someday grow to ...

The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.

The Subaru telescope located at the Mauna Kea Observatory on Hawai'i has found a new world within our Solar System, dubbed "Ammonite" by the team who found it. In 2003, NASA-funded researchers spotted ...

A new analysis of our solar system’s interstellar interloper, 3I/ATLAS, reveal that it’s spewing huge amounts of water — and ...

Interstellar visitor 3I/ATLAS has been constantly changing as it makes its way through our solar system. That's to be ...
