The enormous visitor to our solar system may have been about 8 times the mass of Jupiter, and come nearly as close to the sun ...

A new study suggests that a planet-sized object may have passed through the solar system billions of years ago.

Astronomers have now identified the tiniest brown dwarf, which is believed to be only three to four times the mass of Jupiter. The discovery was made using the James Webb Space Telescope ...

Brown dwarfs are lighter than stars, and heavier than gas giants like Jupiter. And while astronomers had measured the mass of Gliese 229B to be about 70 times that of Jupiter, an object of that ...

Meet the brown dwarf: bigger than a planet, and smaller than a star. A category of its own, it’s one of the strangest objects in the universe. Brown dwarfs typically are defined to have masses ...

Due to their close proximity, the white dwarf strips mass from its low-mass companion. This process has removed about 90 per cent of the mass of the companion, turning it from a star into a brown ...

A First-of-its-kind Brown Dwarf Binary System What makes this discovery particularly exciting is how close the two brown ...

This volume provides a state-of-the-art review of our current knowledge of brown dwarfs and very low-mass stars. The hunt for and study of these elusive objects is currently one of the most dynamic ...

Recent observations, however, reveal that Gliese 229B is actually two brown dwarfs orbiting each other closely, forming a binary system. This was confirmed through studies using telescopes in ...

One of the most stunning examples of a mysterious object in our known universe is CWISE J1249. It streaks through space at a ...

Using the Transiting Exoplanet Survey Satellite (TESS) and the Next Generation Transit Survey (NGTS), an international team ...

Kevin added that they designed the crystal structure of three of the strongest materials, diamond, graphene, and titanium.
