Walkabout the Galaxy
Kuiper Belt Object
Astrophysics and Astronomy | Physics
Stars have a voracious appetite, gobbling up most of the stuff in their immediate neighborhood, leaving just a few scraps to make planets. Sometimes, though, even the planets do not escape the stellar maw. In this episode of Walkabout, the astroquarks discuss a neat observation that shows a star likely gobbled several rocky worlds at some point in its past. Plus, help NASA name a Kuiper Belt Object, and find out the link between the planet eater and Greek mythology in this episode's trivia.
The Fifth Dimension
Here. No, over here. No, not that way. Look, well, like turn your head – I mean – kind of around like – no – not that way. Not that way either. Look over here. In my direction. No, not up! Not down! This way! In the other – you know – like over here! Oh forget it! The fifth spatial dimension is happy to sponsor your walkabout four-dimensional (boring!) spacetime, and no endorsement or affiliation with the musical group 5th Dimension is implied.
