Zach Vanderbosch has spent nearly 300 nights at McDonald Observatory studying the dead stars known as white dwarfs, and the orbiting disks of debris made up of these stars’ former planets. He will receive his PhD this month.
Astronomers at McDonald Observatory have discovered an unusually massive black hole in at the heart of one of the Milky Way's satellite galaxies that could signal changes in our understanding of galaxy evolution.
A international team including Danielle Berg and John Chisholm have confirmed that what flows into a galaxy is a lot cleaner than what flows out. This galactic gas cycle regulates the creation of stars. The study provides a concrete benchmark to test theories of galaxy evolution.
The little Pleiades star cluster glitters high overhead on January evenings. If you see it out of the corner of your eye, it looks like a smudge of light. Look more directly, though, and you will see a tiny dipper formed by six fairly bright stars.
