All the waiting is over, we’ve finally seen the image of the event horizon from the supermassive black hole at the heart of the Milky Way. Different shaped blobs! And a black circle in the middle. What are we looking at?
: George’s Random Astronomical Object presents Messier 61. The center of this barred spiral galaxy contains multiple regions where stars are forming as well as an inactive supermassive black home that needs some caffeine.
The closest black hole is in fact a vampire star system. Listen to @WSHCrew discussion with Dr. Abigail Fros. Also earth-like planet in dead star’s habitable zone, the impact of the war, and aurora in Mars
Time for news roundup. @WSHCrew talk about neutrinos, dead planet crashing into dead stars, galaxies loses their dark matter, auroras in Jupiter, black hole, and new type of neutron stars.
This week, @wSHCrew discuss with Dr. Ralph McNutt about Interstellar Probe Mission. Also news round-up about JWST, stellar mass black hole, new image of the heart of Milky Way, and how is it like to apply to be astronaut.
Using the ESO’s VLTI, scientists have obtained the deepest and sharpest images of Sagittarius A*. They tracked the orbits of stars and were able to more precisely measure the mass of the black hole.
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!
