NASA's James Webb Space Telescope has been unwaveringly focused on our universe. With its unprecedented power to detect and ...

The first and most famous "failed star" discovered by humanity isn't one brown dwarf, but two! The duo comprising Gliese 229B are so tightly bound they orbit each other in 12 days.

So the brown dwarf that three decades ago was named Gliese 229B is now recognized as Gliese 229Ba, with a mass 38 times greater than our solar system's largest planet Jupiter, and Gliese 229Bb ...

With the help of the James Webb Space Telescope (JWST), a team of researchers has found the smallest brown dwarf we know of to date. And it's accompanied by two others, equally as mysterious. The ...

Orbiting a star around 1,400 light-years away, astronomers have found a brown dwarf that is much hotter than any other measured, even exceeding the temperature of our own sun.

The first brown dwarf, called Gliese 229B, was discovered in 1995, but its mass was inexplicably large, says Jerry Xuan at ...

Brown dwarf binaries are thought to form like binary stars from the collapse of a massive cloud of gas to form two stellar bodies. In March 2024, using the Hubble Space Telescope, ...

The twins orbit a small star about 18 light-years away. A light-year is 5.8 trillion miles. Astronomers have spotted brown dwarf pairs before, but these two whip around at much closer range.

This illustration provided by Caltech depicts the orbits of brown dwarf twins, Gliese 229Ba and Gliese 229Bb, with a separation only 16 times larger than the distance between Earth and the Moon.

“If the brown dwarf was closer and then moved out, that changes the whole dynamical environment of the system,” he said. “Maybe there were other planets that were thrown out, and what we see ...

So the brown dwarf that three decades ago was named Gliese 229B is now recognized as Gliese 229Ba, with a mass 38 times greater than our solar system's largest planet Jupiter, ...

NEW YORK (AP) — A celestial object discovered decades ago is actually twins orbiting each other, a new study confirms. Scientists have puzzled over the object known as Gliese 229B, the first ...
