It wouldn't be a #NationalPicnicDay without ants! Commonly called the Ant Nebula, this flamboy-ant planetary nebula is located about 5,000 light years from Earth. Roughly 2 light years across, it's radially expanding at more than 175,000 kilometers per hour!pic.twitter.com/9r2qLQEFKU

Scientists have discovered an important type of titanium blasting out of famous supernova, Cassiopeia A. This new result could be a major step in understanding exactly how some of the most massive stars explode. More at: http://s.si.edu/CasaTi pic.twitter.com/aDeEYKbtpJ

In 1572, astronomer Tycho Brahe observed & studied the explosion of a star that became known as Tycho's supernova. The explosion left behind a multimillion-degree cloud of expanding debris (green & yellow) and ultra-energetic electrons in the blast's outer shock wave (blue).pic.twitter.com/hCIeB9UUHH

Congratulations on the first flight of a powered aircraft on another planet, Ingenuity #MarsHelicopter team! Watch an analysis of Ingenuity's first flight & what's to come at 2pm ET (18:00 UTC): https://go.nasa.gov/3v74wzR pic.twitter.com/wA56xCuiP6

The black hole at the center of Hercules A is over 1,000 times as massive as the one in the center of our Milky Way galaxy. Jets of particles almost a million light years long stream away from this beastly-but-beautiful supermassive black hole. #BlackHoleWeekpic.twitter.com/eD5IBjbxlC

Chandra, @ehtelescope, and @NASANuSTAR will all be observing our Milky Way's supermassive black hole, Sagittarius A* later today! In the optimistic words of Dr. Sera Markoff, let's all "hope for a whopping flare!" #BlackHoleWeekpic.twitter.com/ckN4q5UYsY

Sera Markoff is an astrophysics prof at the University of Amsterdam and is currently EHT Science Council vice-chair. She leads the “jetsetters” research group focusing on black holes of all sizes, especially their jets. When not physics-ing she obsesses over music, cats & food.pic.twitter.com/5FvcJ0IIje

Daryl Haggard is an Associate Professor of Physics at McGill University in the McGill Space Institute. She loves black holes, children, hiking, & cute dogs. She studies the coolest stuff in the Universe: the Galactic center/Sgr A*, gravitational wave sources, black holes, & more.pic.twitter.com/0vrkIhpATS

Do you have questions about the famous M87 #BlackHole or about black holes in general? Reply with your questions below and science experts @DarylHaggard and @ProfSeraMarkoff will answer them today at 12pm EDT (UTC-04:00)! #BlackHoleWeekpic.twitter.com/Q92C1rSy6H

In 2019, the Event Horizon Telescope released the first direct image of the black hole in galaxy M87. In a quest to learn more, coordinated observations with 19 of the world's most powerful telescopes have now collected light from across the spectrum. http://s.si.edu/M87_bh pic.twitter.com/YEjjGMkuPQ

And the excitement continues! #BlackHoleWeekpic.twitter.com/RkOOAEmyYN

Hunting black holes is tricky! Chandra can find them by searching for light from a hot disk of material swirling around a black hole, called an accretion disk. Friction between particles in the disk heats them to many millions of degrees, and they produce X-rays. #BlackHoleWeekpic.twitter.com/22Vq8rdArd

(2/2) Located about 9.9 billion light years from Earth, this supermassive black hole is triggering star formation in multiple galaxies across more than a million light years! The image spans roughly 3.4 million light years. More at: https://s.si.edu/bhpositive pic.twitter.com/SvinXEXPQd
