Astronomers are uncovering the earliest stages of planet formation with the help of technologies like the James Webb Space Telescope (JWST). Recent findings from the Butterfly Nebula, 3,400 ...

Scientists believe giant impacts – like the one depicted in this artist’s concept – occurred on Mars 4.5 billion years ago, injecting debris from the impact deep into the planet’s mantle. NASA’s ...

A new model that incorporates data gathered by the JWST could help scientists understand the composition and mass of objects ...

Astronomers have long grappled with the question, “How do planets form?” A new collaboration among Arizona State University (ASU) , Michigan State University (MSU) and Lawrence Livermore National ...

Astronomers have discovered the raw ingredients of planets orbiting two infant stars, offering a glimpse into how new worlds ...

Astronomers are using radio pulses from space to find missing baryonic matter and learn about supermassive black holes, ...

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical elements, which enriched the universe and allowed the next generations of ...

A new study challenges the dream of water-rich “Hycean” planets like K2-18b, suggesting that most sub-Neptunes lose their water deep into their interiors during formation. Instead of vast oceans, ...

An international research collaboration has used advanced computer simulations to investigate how faint radio signals from ...

Normally when a medium-size star dies, it blasts away the bulk of material in its system. The Hubble discovery was surprising to astronomers because most would predict the distant icy worlds to be ...
