As we approach the end of Crash Course Astronomy, it’s time now to acknowledge that our Universe’s days are numbered. Stars will die out after a few trillion years, protons will decay and matter will dissolve after a thousand trillion...

While Jupiter is nowhere near massive enough to initiate fusion in its core, there are even more massive objects out there that fall just short of that achievement as well called brown dwarfs. Brown dwarfs, have a mass that places them...

Physics Girl astrophysics series - Brown Dwarfs are among the most recently observed objects in the universe. They have at MOST 8% the mass of the Sun. The lower mass boundary is not known! So they are halfway between stars and gas giant...

Finding black rocks in the darkness of space isn’t easy, but new methods could help spot them all.

Why are stars different brightness, colours and sizes? A look at the main sequence of stars, and what makes stars different from each other.

We've learned about the stellar life cycle, so we know what happens to smaller stars like ours, and we know what happens to larger stars that become neutron stars and black holes. But what are the limits on either side? How small can a...
