Faint super-planet discovered by radio telescope

For the first time, astronomers have used observations from a radio telescope and a pair of observatories on Maunakea to discover and characterize a cold brown dwarf, also known as a "super planet" or "failed star." The discovery, ...

Radio observations detect new brown dwarf

Using the Low-Frequency Array (LOFAR) radio telescope, an international team of astronomers has discovered a new radio source that turns out to be a cold brown dwarf. The object, designated BDR 1750+3809, is so far the first ...

Citizen scientists discover dozens of brown dwarfs

How complete is our census of the Sun's closest neighbors? Astronomers and a team of data-sleuthing volunteers participating in Backyard Worlds: Planet 9, a citizen science project, have discovered roughly 100 cool worlds ...
