Feature Guest: Alison Sills
It’s a phenomenon so mysterious one astronomer wondered if it could be evidence of an advanced extraterrestrial intelligence. Meet blue straggers, the black sheeps of the stellar family. Today we’re joined at The Star Spot by Professor Alison Sills to learn all about the stars that shouldn’t exist.
Current in Space
Dave mesmerizes us with the carnival funhouse like effect around black holes, where the warping of space and time is so intense you can see the front and back of blackholes simultaneously. Celine discusses an upcoming unmanned mission to drill the moon for lunar samples and establish the viability of a future human outpost. And while you may have heard of the Great Red Spot on Jupiter, Tony wonders if the entire spot is red, why it’s red and why so little else on the gas giant shares the iconic colour. Finally Yonna brings us news of Europe’s first space plane set to launch shortly.
