Astronomers find bounty of failed stars: One youngster only six times heftier than Jupiter

Astronomers have found 24 new brown dwarfs. a brown dwarf is a failed star that after a length of time shows planet like characteristics such as atmospheres. The exciting part about these new found brown dwarfs is their relative small size, some of them being from 6 to 20 times the size of Jupiter. This means that astronomical objects much bigger than Jupiter but depending on size form the same way as stars if they are big or form like planets if they are small. Astronomers used the combination of Surbaru Telescope and the Very Large Telescope to to locate and view these brown dwarfs both on optical and infrared wavelengths in the NGC 1333 and rho Ophiuchi star clusters.

That's a cool article. I think the most interesting thing that I took away from it is again how big stars are. These brown dwarfs are said to be considered "failed stars" yet they are still six times as big as Jupiter at their smallest.

This article is very informative. I had no idea that failed stars were called brown dwarfs. I also didn't know that they could be so small in comparison to other stars. I've always pictured stars to be so massive that they are around the size of our Sun, but now I realize that stars can form at a much smaller size. Thanks for putting up this article. I really learned a lot from it.

I think brown dwarfs are awesome, but they aren't stars, they are sub-stellar, meaning they do not undergo fusion. They are basically planets that formed like a star. I wonder if there are brown dwarfs that are smaller than Jupiter, although it would be extremely hard to find such an object.

This article is very useful and interesting at the same time. Brown dwarf stars are very unique i think.

Brown dorfs appear to be incredibly worth investigating. If they have traits such as atmospheres, could they potentially have other planet-like characteristics?

I find this article extremely interesting. Before this article I never really knew what a brown dwarf star was and its different characteristics. It's pretty crazy how astronomers have found 24 new ones. Thanks for posting this article, i found it very interesting and a helpful.
