First image of Ultima Thule imaged from New Horizons. They think they're approaching it from one of it's poles.

It will take 20 months to get all the data collected in tonight's flyby.

So as of a couple minutes ago, New Horizons just passed by Ultima Thule, the closest it's come to an object since about 30 minutes after liftoff. It will phone home in a few hours, live stream stuff resumes around 7am PST.

How did they get ripples in the steel though?

it ain't their first rokkitship, and ship builders have been producing unrippled steel plating since the merrimac.

did they go cheap on a trivial aesthetic? I don't think they're incompetent and I also doubt the ripples matter. That was a decision to not care.

Might be better than sitting here in my work chair waiting to die!

I'd miss my forumbros though.
You could still shit post. Just everything would be like 6-10 minutes old when you see new messages.

Queen's Brian May is also an astrophysicist and wrote a song about New Horizons.

Rofl:


Latest coming into better focus. It won't be until February until we have the highest resolution images that were taken. A lot of science will be coming down for a long time. Here's the latest image (edit: actually, might just be a better processed first image).


Q&A ongoing:


Anyways, the big thing so far today is they were able to confirm the probe survived the encounter. The trickle of low res images begins soon.

Initial science and photo(s) of the flyby to be revealed in the presser that starts in a few minutes:

Wow. Contact binary confirmed.

It is red (real color photo, LORRI image and then the combined result)

China may have just landed their Rover on the dark side of the Moon.

So they go faster.


They're either going to be red, blue, or green I guess. Based on how our eyes work. Our sun is greenish yellow, right? It may be no more complex than color theory and an indication that there was more heavy red stuff in the protoplanetary disc than blue or green. A lot of words to say it's red because it's red. Not very satisfying. Maybe there's a better reason.

Most of the not-star solar system is red though. Just Jupiter being mostly red makes that true. So really it might just be initial conditions. Might just be that simple. Probably also something fundamental about how light works. Earth is pretty red underneath the water and biomass.

Thanks, no idea why copy-pasting the URL didn't work. In the end I had to click on the "send as e-mail" link and copy that link over.

Edit: the link in my original should work now.
