Aug 3rd: What’s So Groovy About Gravitational Waves?
What are gravitational waves? What makes them? How can we detect them here on Earth, and why is it a big deal? I discuss these questions and more in today’s Ask a Spaceman!
Jun 12th: The Earliest Supermassive Black Hole and Quasar
Xiaohui Fan discusses the discovery of the most distant supermassive black hole and quasar discovery and what we can learn from these objects about the early history of the universe.

What is a black hole firewall? How does it solve some paradoxes when it comes to black holes? Do the firewalls actually exist? I discuss these questions and more in today’s Ask a Spaceman!
May 27th: Tiny ‘Unicorn’ Black Hole Found in Milky Way is Closest One to Earth
A tiny black hole, only three solar masses, has been found inside the Milky Way in the constellation Monoceros. One of the smallest black holes ever found, it is also the closest one to Earth. Plus, Perseverance, Gaia, a brown dwarf, new images of Jupiter, seismic monitoring from space, and this week’s What’s Up.

Jan 14th: Primordial Black Holes, Dark Matter, and… the Multiverse?
Theoretical physicists have found a way to possibly detect primordial black holes which could lead to answers about dark matter and maybe even the existence of a multiverse.
Dec 24th: Missing Black Hole Continues To Mystify Scientists
A massive black hole should be in galaxy cluster Abell 2261. Observations with Chandra and Hubble haven’t located it. Plus, classifying supernovae with AI, neutron stars, the lithium composition problem, and more planetary science.
Dec 10th: Black Hole’s Dust Ring Casting Shadows
Once again, we find that dust is the culprit, this time causing a black hole to cast shadows out from the heart of its galaxy. Plus, a megaflood on ancient Mars, a fossil galaxy in the Milky Way, another minimoon for Earth, newborn jets and more.
