First Picture of Black Hole

April 12th, 2019 No comments
The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. In coordinated press conferences across the globe, EHT researchers revealed that they succeeded, unveiling the first direct visual evidence of the supermassive black hole in the centre of Messier 87 and its shadow. The shadow of a black hole seen here is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape. The black hole’s boundary — the event horizon from which the EHT takes its name — is around 2.5 times smaller than the shadow it casts and measures just under 40 billion km across. While this may sound large, this ring is only about 40 microarcseconds across — equivalent to measuring the length of a credit card on the surface of the Moon. Although the telescopes making up the EHT are not physically connected, they are able to synchronize their recorded data with atomic clocks — hydrogen masers — which precisely time their observations. These observations were collected at a wavelength of 1.3 mm during a 2017 global campaign. Each telescope of the EHT produced enormous amounts of data – roughly 350 terabytes per day – which was stored on high-performance helium-filled hard drives. These data were flown to highly specialised supercomputers — known as correlators — at the Max Planck Institute for Radio Astronomy and MIT Haystack Observatory to be combined. They were then painstakingly converted into an image using novel computational tools developed by the collaboration.

And here is a TED video on how it was done…..

Apollo 11 – New Documentary

March 2nd, 2019 No comments

Just saw a story on the new Apollo 11 documentary out today. They dug into the NASA archives for never before seen footage shot it large format film (so it looks like HD).

I’ve got to see this…I hope it comes to the Pink Palace in Memphis!

Passing of the Opportunity Mars Rover

February 18th, 2019 No comments

This past week, NASA declared the end of the Mars Opportunity Rover mission. For a little robot rover that was supposed to last 90 days on the surface of Mars, this little robot blew away all expectations by lasting 15 YEARS! It showed Mars had running water on its surface at some point in its history and made many other scientific discoveries.

Opportunity…you will be missed.

Hopefully, someday, earthlings will be able to bring you home so you can be displayed in the Smithsonian Air and Space Museum (wouldn’t that be great!).
