DailyDirt: Exploring Our Solar System
from the urls-we-dig-up dept
Our solar system is a pretty big place, and we haven't really seen that much of it. But as we send out more and more probes and get fancier telescopes, we're learning about a ton of interesting phenomena that occur beyond our own planet. Here are just a few fascinating factoids and links on how we're exploring space without sending astronauts anywhere (yet).- While the Earth and other rocky objects in our solar systems aren't perfectly round, our Sun is remarkably spherical... almost too spherical. The Sun isn't perfectly spherical, but it's actually one of the roundest objects humans have ever measured, and it's a bit puzzling why it should be so round. [url]
- NASA's Cassini spacecraft has discovered that Saturn's moon Titan could hold bodies of liquid water under its crust. This could mean there's yet another place in our solar system with water that could possibly sustain life. [url]
- A geochronometer is an instrument that could help determine how old various things in our solar system are. Portable geochronometers could be sent to other planets (like Mars) to improve our estimates of how long it takes for certain planetary features to develop. [url]
