For centuries, astronomers faced the challenge of classifying objects in space based on their appearance. When observing an ...

Distinguishing between brown dwarfs and giant planets has confused astronomers, but a clear separating factor has finally been identified.

For decades, astronomers have struggled to differentiate giant planets from brown dwarfs, a class of objects more massive ...

The boundary between stars and planets appears increasingly indistinct. Objects such as brown dwarfs, neither fully stars nor ...

How can scientists use spin as a fossil record for planetary evolution? This is what a recent study accepted for publication in The Astronomical Journal ho | Space ...

It is difficult to distinguish between the largest planets and the smallest brown dwarfs, stellar objects that were never massive enough to undergo nuclear fusion. Brown dwarfs tend to be heavier ...

Brown dwarfs are often called “failed stars” because they are too small to keep nuclear fusion going in their cores, the process that makes stars shine. These objects sit somewhere between planets and ...

Although brown dwarfs and giant gas planets are very similar, making differentiation difficult. Now, a crucial difference has ...

A detection of phosphine in the atmosphere of a brown dwarf 54 light-years from Earth deepens the mystery of phosphorus chemistry throughout the Milky Way. An ancient object more than 10 billion years ...

Spin separates giant planets from 'failed stars' Clearest evidence yet that giant planets spin faster than their cosmic lookalikes. (Nanowerk News) Astronomers have ...

Figure1: Infrared image showing the directly imaged brown dwarf companion J1446B (dot indicated by the arrow). The central red dwarf (J1446) is masked in white during image processing. The scale bar ...

An artist’s impression of the stellar dimming event caused by a brown dwarf or super-Jupiter with massive rings (foreground) forming an opaque “saucer” through which some light from the star ...
