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 ...

The presence of deuterium, an isotope of hydrogen, in 3I/ATLAS suggests the interstellar comet formed in a much colder place ...

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 ...

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 ...

Astronomers have identified an enormous "growth spurt" in a so-called rogue planet. Unlike the planets in our solar system, these objects do not orbit stars, free-floating on their own instead. The ...

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 ...
