Red Dwarf Stars: The Embers of Creation

Facebook for Space Fans: http://facebook.com/SpaceFan

Been wanting to do a video on red dwarf stars for a long time. I love the fact that they are going to be the only stars left in a few trillion years.

Can you look into Tres-2b?

I'm really interest in the information you can provide regarding this planet?

@funnyfucker666 Check out Space Fan News #28, I talk about it there.  Cool stuff.

BE THE NARRATOR FOR A SCIENCE SHOW!!

Wow. I got goosebumps during the last seconds of the video.

One day trillions of year from now the last red dwarf will flicker out of existence leaving a completely dark universe filled with evenly spread out atoms.

the skies will be dark.......but wel still hear epic guitsr solos XD

Actually, the Sun is large enough to begin helium burning at its core. This, in fact, is what will cause the Sun's expansion into a red giant. Helium will fuse into carbon and oxygen, but the core will not get hot enough to initiate carbon burning. The Sun will ultimately collapse into a carbon-oxygen white dwarf.

@gustyvedova

The Sun is far too small to become a supernova; it will end life as a white dwarf after going through a red giant phase.

In the largest sense, of course, it *is* theory, because we haven't actually sent instruments into a star. But let's be clear that "theory" doesn't mean "wild guess". We know a great deal about the behavior of gases and also about nuclear reactions, among other relevant processes. That allows us to write equations that describe the internal structure, and make predictions (such as neutrino emission rates) which have been verified by measurement.

@pseudorandomly Aah ok then, thanx ^^

@jaybow1982

The material from supernovas, along with existing gas clouds, can and does form new stars. In fact, all of the material on Earth that's heavier than helium comes from supernova explosions before the birth of the Sun.

@sighmoon

The helium produced is bound up inside the star -- red dwarf stars don't explode, so there is no way for the helium to be dispersed into space to form new stars.

[ndyt]

This implies there are a whole lot of brown dwarfs out there = dark mater people! XD

@chaosth30ry77

Eventually, the gas that forms new stars will be exhausted or so thinly spread out that new stars cannot form. In the Milky Way, for example, only about 10% of the original star-forming material remains. The increase in the size of the Universe merely stretches the distance between galaxies and has no bearing on star formation.
