A Busy Day for Space Fans   Leave a comment

So where does one begin on a day like today? I can’t honestly say what story could top seeing¬†a photograph of an actual black hole. But the news certainly is fascinating. And check out the link. There’s a complete picture of Messier 87, a giant galaxy some 55 million light years away, located in Virgo.

Einstein theorized in a paper published in 1915 that star’s light rays curved around the sun during an eclipse. That meant the stars appeared about 1.75 second of arc away from their positions.

In May 29, 1919, when a six-minute total eclipse in Brazil caused British astronomer Arthur Eddington to determine that light rays from other stars bent when subjected to the gravitational field of our sun.  He proved this through the use of photographs, and others have proven it since.

Jump to 2016. MIT graduate student Katie Bouman created the algorithm that produced the first image of the black hole. Her contributions seem to be a bit underreported, but thanks to her work, we now see the image pictured above.

The second big story (to me at least) is Falcon Heavy. It was supposed to launch today, but thanks to high winds aloft, we’re going to have to wait until tomorrow. But the cool thing about it is its three boosters, all expected to land perfectly. I’m always fascinated by this new generation of rockets. Elon Musk, for all his faults, is a genius. Not only did he create a better class of rockets, partly recyclable, he also made their capsules so sleekly modern.

And lastly, on April 11 NASA will host a teleconference on its study of its astronaut twins, Mark Kelly and Scott Kelly. This eagerly-awaited report will detail how Scott Kelly was affected by living in the ISS for 340 days, as compared to his twin brother, Mark Kelly, who remained on Earth. So far, these are the only twins who have both served on the ISS, and, as such, are uniquely qualified for this important study.
