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 ...

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

is roughly 13 times the mass of Jupiter, and is located just 20 light-years from Earth. It's also spinning at a breakneck speed, completing a full rotation every 2.4 hours. Thanks to the JWST's ...

It's rapidly spinning, and at some 13 times the mass of Jupiter, it could be a rogue planet speeding around the cosmos, or possibly a failed star, called a brown dwarf. An instrument on Webb ...

A new image from the James Webb Space Telescope shows a stunning and fashionable sight: the Sombrero Galaxy, named for its resemblance to the traditional Mexican hat. With its wide, flat shape ...

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.

A phantom “Super-Jupiter” 13 times more massive than our ... Although discovered in 2006, the “free-floating planetary-mass object” known as SIMP 0136 has continued to stump astronomers ...

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 ...

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 ...

How do rogue planetary-mass objects, celestial bodies that fall between planets and stars in size, come into existence? An international team of astronomers, including researchers from the University ...

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 ...

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 ...
