A planet-like object has been found to be orbiting a cold, miniature star called a brown dwarf, calling into question just what it means to be a planet.
Brown dwarfs are not quite massive enough to be full-fledged stars; they are not dense or hot enough in their cores to ignite nuclear fusion, the process that powers stars.

A pair of failed stars takes the record of being the dimmest bulbs ever detected, astronomers find.
Each of the substellar objects, called brown dwarfs, is one million times fainter than the sun in total light on the electromagnetic spectrum, and at least one billion times fainter in visible light alone.
A brown dwarf is a compact ball of gas floating freely in space that's too cool and lightweight to generate the thermonuclear fusion that powers real stars, but too warm and massive to be considered a planet.
This artist's concept shows the brown dwarf twins, the dimmest pair of star-like bodies known to date, referred to as 2M 0939. The twins, which are about the same size, are drawn as if they were viewed close to one of the bodies. Credit: NASA/JPL-Caltech

Brown dwarfs are the oddballs of the cosmos, more massive than planets but not heavy enough to generate the thermonuclear fusion that powers real stars. Now astronomers have found the coldest brown dwarf to date.
The failed star might represent a new class of objects that are a missing link between planets and stars

Not a healthy system. This is not a sign of wonders, rather a sign of darksider consciousness in our duality. All stars are in binary system and represent our collective consciousness, or the Light, or Heaven/the Beyond with us. Dwarf stars represent something else in the duality.

Ehm, could you maybe elaborate on this a little bit? I'm not getting what you mean at all.
Thanks!

I wonder how much of our current understandings of the universe is left a 100 years from now.

With all these new brown drawfs around, some with planets orbiting them. I suppose that there could be life on them. obviosly not like ours but life!. with all these lifeforms on our planet in like lava or deep ocean, cant really rule it out.
With our current tech levels, could we send probes there? if so how long would it take. Maybe we could learn allot?

But there is so much that we as a race can answer. Oh if i could just plug my mind into a machine of all knowledge, lol. all i want to do is learn.
