And the earth was without form and void, and darkness was upon the face of the deep. Sometimes, if the night is dark and clear enough, you can look up and see the Milky Way in its arc across the sky.

Ever since scientists started looking at meteorites with microscopes, they’ve been puzzled–and fascinated–by what’s inside. Most meteorites are made of tiny beads of glass that date back to the ...

Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

Researchers rarely get a glimpse of an interstellar object up close like 3I-ATLAS, so they have jumped on the opportunity to learn about its composition, which can reveal how planet systems are made.

What: Astronomers using JWST and ALMA have captured the earliest known stage of planet formation around the protostar ...

As telescopes have become more powerful, it’s turned out our solar system is not the only game in town: There are millions of ...

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, ...

What: Comet 3I/ATLAS reached perihelion on October 30, 2025. This special SETI Live explored what scientists have learned ...

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.

Astronomers have identified 3I/ATLAS, an ancient, ice-rich interstellar comet potentially older than our solar system.
