THOUSANDS. #Repost @nasa ・・・
A black hole has a gravitational pull so intense that nothing, not even light, can escape it! Using data from the Chandra X-Ray Observatory (@nasachandraxray), astronomers discovered evidence for thousands of black holes located near the center of our Milky Way galaxy.
Pictured here is a black hole bounty consisting of stellar-mass black holes, which typically weigh between five to 30 times the mass of our Sun. These newly identified black holes were found within three light years — a relatively short distance on cosmic scales — of the supermassive black hole at our Galaxy’s center known as Sagittarius A.
While a black hole by itself is invisible, when locked in close orbit with a star, high-energy light is produced and can be detected by scientific instruments so that astronomers can learn more about the properties of the black hole.

Enjoying a few last minutes by the pool in the AZ desert before going back to NY swampcrotch season. Thank you, @coachchrisbaran, for shooting #frenchhours, and @suzsturm and Rita for all the luscious food! #lovemyjob @cutactionmedia

The Salish Sea is home to me, @CristinaMittermeier and several members of the @Sea_Legacy Collective. It is also home to one of the most abundant and diverse ecosystems in the world. The endangered southern resident orcas, minke whales, stellar sea lions, and humpback whales are just a few of the iconic and vital species that make the Salish Sea so remarkable and valuable. Take note, @justinpjtrudeau, @liberalca, and @premierrachelnotley – the #KinderMorgan project is far from certain. @Sea_Legacy will continue to defend this coast, our communities, and the climate. This changes nothing.
