Giant stars lurk the heart of the Westerlund 1 cluster.
A region of material similar to the Kuiper belt of our solar system has been directly observed around another star.
A Wolf-Rayet star nicknamed “Nasty 1” is having its hydrogen stolen by a companion star.
Giant stars such as Betelgeuse may appear to dwarf our Sun, but their densities are so low that they are basically red hot vacuums.
Caffau’s star is sometimes called an “impossible star.” It’s actually just an interesting star that we don’t fully understand.
We’ve just discovered the fastest star in our galaxy, and it was likely given its speed by a supernova explosion.
About 70,000 years ago Scholz’s star came within 0.8 light years of the Sun.
We can determine the age of a star by the way sounds move within it.
A star known as HIP 85605 is on a collision course with our solar system. Not a collision course as in Armageddon, or When Worlds Collide, but rather on a path to come within 0.04 parsecs of the Sun. That might seem close, but that would make it more than 8,000 times more distant than Earth at its closest approach (8,000 AU). Distant Eris is only 100 AU by comparison. Given that stellar distances are typically measured in light years, and this encounter would be only 50 light days away, that’s remarkably close by astronomical standards. This close encounter won’t occur for another 400,000 years or so. Currently HIP 85605 is about 16 light years away, so we have time to plan for its visit. But it does raise an interesting question as to how such a close encounter could affect our solar system.
