  1. 💥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:

  2. 💥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).

  6. Stephen Hawking lost a bet—placed in 1974—that Cygnus X-1 was not a black hole. Astronomers used several telescopes including to study Cygnus X-1, which is in fact a black hole about 15 times the mass of the Sun.

  7. 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. ⚫

  9. Chandra, , and 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!" ⚫

  12. 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.

  13. 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.

  15. ⚫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.

    You may be hearing a lot about black holes this week … now listen to their sounds! 🔊 This playlist is filled with data sonifications and podcast episodes featuring these bizarre cosmic creatures: ⚫

  18. 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. ⚫

  19. (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:

  20. Black holes can have a tremendous impact on star formation. They often inject so much energy into a region that it prevents hot gas from cooling down to make stars. In the case of the supermassive black hole featured in this image, it's quite the opposite. (1/2) ⚫
