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.

Yeah, I've seen nothing in the news. I get emails because I kicked in on the Kickstarter, otherwise I wouldn't even know it existed.

Astronomers got a look at the atmosphere of a Super-Earth. Oddly they only found hydrogen and helium, making this less of a "Super-Earth" and more of a Micro-Jupiter. But this discovery is making them question the current model for system formation- which is fine as I've doubted the migrating planet theory.
Still we're now into the realm of analyzing the atmosphere's a exo-planets so we may yet find worlds with oxygen in their atmospheres...

Yeah, I got an email about this from the Hubble Team. It just gets weirder and weirder out there. The article said that the atmosphere is very clear, which makes me wonder what the thing looks like.

But, yeah, it's just amazing that we're now able to draw conclusions about a planet's atmosphere. It won't be long now till we're seeing those oxygen signatures. :yes:

So there might be tartigrades on the Moon now. :unsure:

Indestructible Tardigrades and human DNA on the Moon-- there's an SF novel waiting to happen. :quill:

"Moss Piglets?" Where do Tardigrades get all these weird nicknames? :lol:

Today's the day India tried to land their rover on the South pole of the Moon, but it looks like something went awry at the last minute. I was watching it live on some YouTube channel that had intermittent English translations. Everybody was happy and clapping and then the little red line on the graph deviated from the little green line on the graph and the mood changed. They didn't confirm anything for about a half hour, but you could tell something was wrong. :(

Oops, didn't notice this post earlier. :blush:

Yeah, this was disappointing. :no: Feel bad for India.
