Black holes do not emit any light of their own making them impossible to see directly with telescopes. So, what’s the closest one to us?

Dec 10th: The Closest Black Hole to Earth
Today’s @NOIRLabAstro will have @halfastro discuss with Kareem El-Badry on how he led a team that discovered a black hole that is not actively consuming material and that is also the closest currently known black hole to Earth.
Nov 18th: Up, Up & Away with Dr. Jacob Izraelevitz and JPL’s Venus Aerial Robotic Balloons

Aug 19th: Rogue Black Hole Possibly Found in Milky Way
After six years of Hubble Space Telescopes and the hypothesis that millions of black holes exist in the Milky Way, scientists have finally found direct evidence for the rogue black hole. More about it at #365daysOfAstro
Aug 9th: Well, Not Really
If we want a lunar orbiting space station, couldn’t we just send the ISS there? Could bacteria have hopped aboard the Venera probes and seeded Venus’ atmosphere? Find the answer with @CheapAstro at #365DaysOfAstro
Jun 14th: Found: Dying Galaxies Containing Active Black Holes
Astronomers combined observations of far distant galaxies exhibiting no signs of star formation and found active supermassive black holes that may have contributed to the evolution of their parent galaxies. Plus, rocket launches, detecting earthquakes, and why Uranus and Neptune are different shades of blue.
Jun 7th: How Do Black Holes Affect Their Galaxies?
How do giant black holes shut off star formation? How do they turn it back on? Which came first, the black hole or the galaxy? I discuss these questions and more in today’s Ask a Spaceman!
Jun 6th: Light Echoes
Just as sound can echo off distant objects, light can echo too. And the echoes of light bouncing off stellar remnants, black hole accretion disks, and clouds of gas and dust provide astronomers with another method of probing the distant cosmos.
Jun 1st: Awesome Astronomy June 2022 News Round-up
Time for your June sky guide and news round up with @AwesomeAstroPod. This month we have A companion star that survived a supernova, dark matter stripped away in galaxies, and of course the image of Sagittarius A*.
