The world’s premier space observatory has spotted a mysterious and huge, free-floating planetary-mass object that’s “just 20 light-years from Earth,” NASA announced. Researchers recently used the ...

Using the James Webb Space Telescope (JWST), astronomers have peered into the atmosphere of a cosmic body that could be a rogue planet or a "failed star." Either way, the world wanders the cosmos ...

The James Webb Space Telescope is investigating the Flame Nebula, hunting for "failed stars" to better understand how brown ...

The James Webb Space Telescope is helping scientists study a strange mass about 20 light-years from Earth. Traveling unpredictably through the cosmos, the mass is thought to be either a rogue planet ...

The planet's mass is estimated to be at least 1.3 Jupiter masses. However, given that the inclination of GJ 2126 b is unknown, its mass could be much greater and the possibility that this object ...

and weigh less than 13 times the mass of Jupiter. While they have been spotted in abundance in young star clusters such as the Trapezium Cluster in Orion, their origin has puzzled scientists.

The mass of these objects is less than 13 times that of Jupiter. They are often observed in young star clusters like the Trapezium Cluster in Orion. While their existence is well-documented ...

These bodies with masses between 13 and 75 times the mass of Jupiter (or 1.3% to 7.5% the mass of the sun) are, therefore, much fainter than regular main sequence stars, despite the fact that some ...
