Once again the universe gives away a new secret.
Two brown dwarf stars circling each other. One has about 20 times the mass of Jupiter and the other 5 to 10 times.
This is again a discovery what makes us pondering.
Planets have been discovered which had the same mass or an even bigger mass then the smaller Brown dwarf star. Yet stars and planets are believed to
evolve differently from each other.
Stars form as clouds of gas and dust falls in to itself and planets are believed to be formed from a secretion disk around a newly formed star.
Brown dwarf stars are the universes almost stars. just lacking the mass and heat to start nuclear fusion inside there cores.
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
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.

of Jupiter (at left), and its companion, about 7 times the mass of Jupiter (at right) are shown in this illustration. Credit: NASA, ESA, and K.

And here is another article related to it.
Found: The Dimmest Bulbs in Space
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
I wonder how much of our current understandings of the universe is left a 100 years from now.
Little discoveries like these make us change it continuously and with new technologies this process seems to go faster and faster.

conventional theory. Credit: Robert Roy Britt, SPACE.com.
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
What great times we live in !
