In 1975, Kip Thorne (BS '62, and the Richard P. Feynman Professor of Theoretical Physics, Emeritus) and then-Caltech postdoctoral fellow Anna Żytkow sought the answer to an intriguing question: Would it be possible to have a star that had a neutron star as its core—that is, a hot, dense star composed entirely of neutrons within another more traditional star? Nearly 40 years later, astronomers believe they may have found such an object: a star labeled HV 2112 and located in the Small Magellanic Cloud, a dwarf galaxy that is a near neighbor of the Milky Way and visible to the naked eye. We recently sat down with Thorne to ask how it feels to have astronomers discover something whose existence he postulated decades before.

If you ask Andy Ingersoll how Caltech has contributed to our understanding of the universe, he will tell you, "Caltech invented planetary science!" And since the field's origins just fifty years ago, Caltech has become one of the top centers of planetary science research in the world.

By incorporating the data of individual stars into whole-galaxy models, Caltech researchers can look at the actual effects of star feedback—how radiation from stars "pushes" on galactic matter—in the galaxies they study.
A still image from a FIRE simulation video, showing the gases in a galaxy. Magenta is cold molecular/atomic gas, which forms stars; green is warm ionized gas, most of which cools into a galaxy; red is 'hot' gas, which makes up the galaxy halo.

The Nuclear Spectroscopic Telescope Array, or NuSTAR, sees the high-energy X-rays emitted by the densest, hottest regions of the universe. Professor Harrison will describe NuSTAR's unlikely journey and share some of its remarkable results.

Where do you go to look at the stars? Away from city lights, certainly. But if you're serious about peering far out into space, to the observable edges of our universe, at submillimeter wavelengths, you have to do a little better than that.

Himiko, a "space blob" named after a legendary queen from ancient Japan, is a simply enormous galaxy, with a hot glowing gaseous halo extending over 55,000 light-years. Not only is Himiko very large, it is extraordinarily distant, seen at a time approximately 800 million years after the Big Bang.
