For decades, scientists have studied how planets form by looking at young stars nearby, assuming that these environments could be representative of all star systems. However, as astronomers discover ...

New observations of interstellar comet 3I/ATLAS show high levels of deuterated water, suggesting it formed in a colder star ...

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such systems ...

A string of small gas clouds near the Milky Way’s central black hole has puzzled astronomers for years. Now, new observations ...

A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form. Reading time 3 minutes Astronomers have discovered a star system that’s out of ...

Add Yahoo as a preferred source to see more of our stories on Google. Observations of the young HOPS-315 star system show an environment analogous to what our own nascent Solar System would have ...

Two of the objects in the arrangement are cold brown dwarfs, which will serve as a benchmark for others throughout the Milky Way. By Katrina Miller Zenghua Zhang, an astronomer at Nanjing University ...

As the number of exoplanet detections has breached 6,000 and continues to grow, scientists are finding a wide variety of different solar system architectures. Critical to understanding how these ...

Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit around both stars — a first in astronomy. The system’s compact, cold nature ...

This Collection features original research on the mechanisms driving star formation, the lifecycle of various stellar types, and the complex interactions between stars and their environments. The ...

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 ...
