Astronomers have spotted a planetary system being conceived from the swirl of gas and dust surrounding a star — giving us an unprecedented, real-time look at how our solar system would've formed some ...

A region of active star formation in the constellation Ophiuchus is giving astronomers new insights into the conditions in which our own solar system was born. In particular, a new study of the ...

The solar system is 4.54 billion years old, based on rock dating. Gas giants (Jupiter and Saturn) likely formed first. Ice giants (Uranus and Neptune) probably formed next. Rocky planets formed last, ...

The solar system originated from a collapsing cloud of gas and dust approximately 4.5 billion years ago, with the Sun forming in the central region through nuclear fusion and the planets condensing ...

Astronomers using NASA's Hubble Space Telescope have imaged the largest protoplanetary disk ever observed circling a young ...

Astronomers studying a disk of material circling a still-forming star inside our Galaxy have found a tantalizing result — the inner part of the disk is orbiting the protostar in the opposite direction ...

This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA), in ...

Ever wondered how planetary systems like our own solar system form? Thanks to the European Space Agency's Gaia space ...

Researchers have been focusing on the study of our solar system for centuries, looking at the physics, dynamics, as well as the composition of solar system bodies. Our solar system – which includes ...

The James Webb Space Telescope measured a potential moon-forming disk encircling an exoplanet, NASA recently announced, inviting researchers to observe and study moon formation as it happens, while ...

Astrophysicists are mapping a vast, hidden structure in space that appears to guide matter and radiation along a kind of ...
