The horizontal gaps are an imaging artifact, but the rings themselves are a genuine cosmic feature created by a black hole 9 times as massive as the Sun, located 7,800 light years away. https://t.co/1ALWb1qOSu

When light collides with other light, it can transform into particles of matter. This naked version of E=mc2 has just been detected at the RHIC atom-smasher in Long Island. https://t.co/VdSvTwFt8N

Cosmic filaments appear to be the largest rotating structures in the universe: millions of light years wide, hundreds of millions of light years long.
That's a lotta angular momentum. https://t.co/I5BQnDlpXY

Every illustration from Bellicorum instrumentorum liber (Book of Warfare Devices), completed in 1420, is a creative marvel. Like this fanciful concept for a huge, mechanical flamethrower to defend a besieged city. https://t.co/xHrvVCk15w

The most detailed 3D map of the universe includes 100 million galaxies, viewed through the dark "hole" in the sky looking perpendicular to our Milky Way. https://t.co/ut7vQ5Y4Cz

These images of the center of the Milky Way show radio (left) and x-ray emission from forming stars, black holes, supernova explosions, and powerful magnetic fields. https://t.co/xxl3sunq5h

If you had x-ray and radio vision, you'd see amazing things at the center of our galaxy. Oh wait--you DO, courtesy of the Chanda and MeerKAT telescopes. https://t.co/lcK0ZGAh1a

@gregeganSF Eventually we'll get the full family of rovers.

@ProfAbelMendez I just realized that the Harvard co-author of this paper is Rudy Schild, who co-authored some other remarkable scientific tomes.

It took 4 decades to validate the "crazy" idea that Saturn's rings act as an enormous, extremely sensitive seismograph. https://t.co/lFQZaSPdcQ
