And now for some surprises from us ;)
In our next #AoTLeiden speaker Huib van Langevelde will tell us about black holes and how today's wonderful, historic @ehtelescope image came to be! Come learn all about it on the 29th of April! #RealBlackHole#EHTblackhole
If the universe is uniform and infinite, then the sky should be on fire, since there is a star at every point you look. But since you look into the past when looking at distant stars, you eventually reach a cut-off, the big bang. So the sky is black because there was a beginning!
.@Astro_Alex:"My personal goal as a @Space_Station commander is to have all of our experiments done, to keep this fantastic research platform in a good state and to come back home as friends." #IAC2018#Horizons
