ESO Observations Show First Interstellar Asteroid is Like Nothing Seen Before

This artist’s impression shows the first interstellar asteroid: `Oumuamua. This unique object was discovered on 19 October 2017 by the Pan-STARRS 1 telescope in Hawai`i. Subsequent observations from ESO’s Very Large Telescope in Chile and other observatories around the world show that it was travelling through space for millions of years before its chance encounter with our star system. `Oumuamua seems to be a dark red highly-elongated metallic or rocky object, about 400 metres long, and is unlike anything normally found in the Solar System.


A lot of people have been asking what in the world could be similar between MRI brain imaging and infrared astronomy, and today I realised that, beyond coding, looking at image data and general sciencing, it’s one hell of a lot. 

First, MRI machines use liquid helium just like the James Clerk Maxwell Telescope I’ve used before. So the compressor chirp sounds exactly the same, very comforting! And today we’ve travelled to another MRI centre to actually run some tasks sequences to see whether the results are similar to our site. To do so I had to get up super early so I’m exhausted – just like an observing run… and there are lots of computers in the control room, just like an observing run! And only the radiographer/MRI physicists who use the machine daily are allowed to issue the final execution commands, just like an observing run (at a lot of telescopes, anyway)! 

So what I’m trying to say is that there’s no difference.
