See for yourself!

If anything, Mercury is asking us to slow down and take stock of what we have going on in communication already. Mercury in retrograde motion is forcing you to stop and breathe.

Finally after decades of hope and hard work, astronomers finally discovered a planet orbiting the nearest star to our sun: Proxima Centauri. Describing it in human terms leads to some interesting problems!

If it's for real, it's the closest planet beyond our solar system. The closest planet in outer space.

These starkly beautiful illustrations will transport you to distant worlds.

“It is a fascinating object!”

As I was reading about the evidence for the yet-unseen ninth planet, I thought to myself, "Wait a minute. Aren't there already nine planets?" I started listing them off, like you do when you're trying to remember the seven dwarves.

If the predictions are correct -- if Planet 9 actually exists -- then our solar system will better comport with many of those we find elsewhere. And if our solar system is not so special, then there's added reason to suspect that the biology it has spawned may not be so unusual either.
