Walkabout the Galaxy
Comet 29P; dark energy
Astrophysics and Astronomy | Physics
Comet 29P is on an odd, distant orbit, between Jupiter and Saturn, and like a fidgety child sent to the corner, it keeps having unpredictable outbursts. In other planetary systems, the numerous hot jupiter class of planets seem to have a uniform nighttime temperature due to the presence of clouds of rock droplets. Maybe a good name for a song: Rock Droplet? And we'll check in on the latest in Dark Energy news.
Not to be outdone by their flashier cousins comets, active asteroids keep you guessing with the occasional outburst. While they're not toddlers in the Solar System, with ages up to 4.5 billion years, active asteroids might decide to start spewing dust or pebbles, with apparently no provocation whatsoever. So whether you're there to grab some scientific samples or just enjoy a nice microgravity walk around a boulder field, watch your step on active asteroids. But enjoy the view on your world class observatory or space craft flyby. Active asteroids, get comfortable with it (Preparation H).
