Based on X-ray detections from the Neil Gehrels Swift Observatory, scientists used the Chandra X-ray Observatory and found rings called light echoes moving out from a black hole and its companion star, reflecting off the surrounding dust clouds.
Are there really primordial black holes? What do you make of the helical drive? Today @CheapAstro investigates some unsubstantiated claims
Today, @AstronomyCast traveled back in time to answer questions about black hole surfaces, magnetic field strengths, & the speed of gravitons
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!
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!
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.
Time for @AwesomeAstroPod news update and sky guide. This week we have Cygnus X-1 black hole, super-supermassive black hole, the impact that killed dinosaurs, & the mythical planet nine.
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.
