Astronomers discover that the rotation speeds of distant planets reveal how they form and evolve in the universe ...

How do rogue planetary-mass objects -- celestial bodies with masses between stars and planets -- form? An international team of astronomers has used advanced simulations to show that these enigmatic ...

A newly analyzed planetary system spotted by NASA’s TESS mission is challenging long-standing assumptions about how planets ...

This one-million-year-old star-forming region contains thousands of new stars and hundreds of planetary mass objects floating freely in the nebula, not orbiting stars. A groundbreaking study published ...

A baby world just drifting through space without a star to call home has been caught in a record-smashing feeding frenzy. Not only is this the highest growth rate ever recorded for a planetary-mass ...

The Universe still holds many surprises, as demonstrated by this exceptional observation of a dying star devouring the remains of its own planetary system. This phenomenon, captured by some of the ...

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

Rogue planets live by their own rules, freely floating through the cosmos without being bound to a star. With no stellar supervision, those isolated planetary bodies can often behave in unusual ways.

New research from the University of St Andrews has found that giant free floating planets have the potential to form their own miniature planetary systems without the need for a star. In findings ...
