Can we just take a moment to remember how advanced the astronomy of the Maya civilization was?

How they were able to predict eclipses and the motions of Venus and the Moon?

How they invented the concept of zero, independently from the Indians?

How their calendar measured the length of the solar cycle more accurately than the Gregorian calendar?

"Australian researchers say they have found the oldest star in the known universe, 6000 light years from Earth."

"Stellar archaeologists have found some very old stars, hidden in space like a pharoah€’s tomb and holding secrets of the cosmos€’ chemical evolution.

"Astronomers have long supposed that planets can form around brown dwarfs just as they do around ordinary stars. Now they’ve found the first example."

A day in the year of the life of the solar system …
While the animation above is pretty sweet, you’ll really want to go play with the interactive version of this solar system simulator.
You can punch in any year, and let the orbits proceed fast or slow. Use it to learn how the planets align (and don’t), how different bodies orbit, or as an excuse to stare at your screen with your mouth open in amazement. You can even click the “Tychonian” button to see what an Earth-centric solar system would look like!

What if the moon had never formed?

Huge tides generated by the moon – which orbited much closer to Earth when it formed – washed the chemical building blocks for life from land into the oceans and helped stir up the primordial soup. Without it, life may never have arisen, or living things would have very different behavioral patterns to cope with the six-hour day and extreme climate changes that would exist on a moonless Earth.
