The gravity is so strong because matter has been squeezed into a tiny space. With no light getting out, the black holes are invisible to the naked eye. The black hole, Sagittarius A*, is at the center of the Milky Way galaxy.]]> 2020-03-10 18:07:30 UTC https://padlet.com/1203619/wttamp6uackq/wish/457827380 How Do We See A Black Hole? 1203619 https://padlet.com/1203619/wttamp6uackq/wish/457841033 Space telescopes, like Chandra X-Ray Observatory, use special tools find black holes. They use the heat signature surrounding the black hole that is caused from the matter being heated to millions of degrees as it is being pulled into the black hole, creating an X-ray.]]> 2020-03-10 18:21:09 UTC https://padlet.com/1203619/wttamp6uackq/wish/457841033 How Big Are Black Holes 1203619 https://padlet.com/1203619/wttamp6uackq/wish/457852208 NASA says the smallest black holes can be as small as an atom but still have the mass of a mountain. The biggest can have the mass of one million stars or more, and are called "supermassive." Sagittarius A* has the mass of about four and a half million Suns. There is a supermassive black hole at the center of every galaxy.]]> 2020-03-10 18:32:51 UTC https://padlet.com/1203619/wttamp6uackq/wish/457852208 Flares On Sagittarius A* 1203619 https://padlet.com/1203619/wttamp6uackq/wish/479751331 Scientists have noticed odd flares coming from Sagittarius A* about once a day. The cause for the flares is asteroids or comets moving too close to the black hole and being vaporized.]]> 2020-03-28 16:16:51 UTC https://padlet.com/1203619/wttamp6uackq/wish/479751331 Video on Sagittarius A* 1203619 https://padlet.com/1203619/wttamp6uackq/wish/480835653 Click to see video]]> 2020-03-29 18:48:27 UTC https://padlet.com/1203619/wttamp6uackq/wish/480835653 Summary 1203619 https://padlet.com/1203619/wttamp6uackq/wish/480851186 Click to see summary on Sagittarius A* ]]> 2020-03-29 19:02:35 UTC https://padlet.com/1203619/wttamp6uackq/wish/480851186 A Picture of a Flare On Sagittarius A* Taken By Chandra X-Ray Observatory 1203619 https://padlet.com/1203619/wttamp6uackq/wish/480861267 The largest X-ray flare from the Milky Way galaxy.]]> 2020-03-29 19:11:32 UTC https://padlet.com/1203619/wttamp6uackq/wish/480861267 Works Cited 1203619 https://padlet.com/1203619/wttamp6uackq/wish/480868994 Click to see Works Cited]]> 2020-03-29 19:18:33 UTC https://padlet.com/1203619/wttamp6uackq/wish/480868994
