"The goal of this project was to explore the fundamental low-mass limit of the star and brown dwarf formation process." ...

An international team of astronomers reports the detection of two new brown dwarfs orbiting distant stars using NASA's ...

Previous examinations using ground-based tools as well as the Hubble and Spitzer space telescopes indicated SIMP 0136 was ...

The world’s premier space observatory has spotted a mysterious and huge, free-floating planetary-mass object that’s “just 20 ...

The result, they found, were free-floating objects roughly two to three times the mass of Jupiter, although they were sensitive down to 0.5 times the mass of Jupiter. "The goal of this project was ...

How do rogue planetary-mass objects – celestial bodies that fall between planets and stars in size – come into existence? An ...

Free-floating, planetary mass objects are bodies with around 13 times the mass of Jupiter that are often found drifting through young star clusters, such as the Trapezium Cluster in Orion.

The dividing line between gas giant planets and failed stars is blurry at best. The isolated planetary-mass object SIMP ...

Using the James Webb Space Telescope, an international team of researchers has uncovered the hidden complexity of SIMP 0136, ...

This world defied all expectations. Rather than a distant gas giant like Jupiter, 51 Pegasi b was a behemoth half the mass of Jupiter but orbiting astonishingly close to its star, whipping around ...
