And they have successfully imaged the shadow of the event horizon of the gravity of the Black Hole. Our universe at work. :cooldude:

There appears to be a new species of human. Since it seems to share some characteristics with Homo floriensis I imagine that they're both descended off the same ancestors.
It's kind of amazing to think of human-like hominids populating the Philippines more than 700,000 years ago. Three quarters of a million. I wonder what the islands were like then. I kind of didn't even realize they were that old.

^With sea levels lower due to the Ice Age they would actually have been larger.

We can image a black hole here even. :hole:

Good point. And it's very likely that most of the settlements would have been along the shorelines, which means that all evidence is lost forever now. :(

Watch your step on the accretion disk. :lol:

Another possible planet orbiting Proxima Centauri- with emphasis on the word "possible". However judging by the descriptions it sound like it will be a small gas giant or maybe an ice giant.

And in other news (well, not news per se but just really cool) here's a family tree for the Dromaeosauridae!

I would be shocked if there are any stars that have only one planet-- or no planets. Except maybe very near the galactic core. Planets are basically dust and debris around the star, and I can't imagine any star being so clean that it has no planets.

^True, but just the act of finding them is the amazing part. I have an old book about life on other planets from the 40s where the author is insisting that we'd never be able to detect planets around other stars. Look where we are now.

Yeah, it wasn't that long enough that we were barely detecting hints after years of research. Now they're imaging storm systems on alien gas giants.

Here's kind of an interesting and grisly discovery. Human sacrifice in the Iron Age. Definitely some story material there. :book:

^Yeah, a lot of the Bog People appeared to be the victims of human sacrifice. It probably wasn't fun period to be alive. :no:

Talk about great free advertising. Too bad there's not a Star Trek show on to take advantage of it. :lol:

There's been a couple of close calls lately. :lol:

In other news, the Planetary Society's solar sail experiment is making good progress. The first attempt was destroyed in a launch failure a few years ago, but this one seems to be doing well.
