A wild thread:
490 million years ago, the seafloor which would become the city of Baltimore was a serpentinite-hosted hydrothermal vent complex.
Those vents laid the ultramafic structures that would, in 1812, be discovered as America's first chromite mine.
Did Mars once have a vast ocean? This new paper reports a topographic signature of a planet-girdling coastal shelf. This is a new and clearer signal than we saw previously from the deltas and possible shoreline deposits. Very exciting.
is it cake? looks like cake
Not generally a Labour supporter but I don’t think Starmer should resign. He is a good and honest public servant and the best prime minister we have had in a long time.
Humanity did that. Science did that. Publicly-funded research did that. Excellent universities did that. Diversity did that. International cooperation did that.
Artemis II is a perfect example of what we can do at our best.
Welcome home, Integrity crew!
Feels relevant #Artemis
It’s been a big week! Another new paper out in Palaios describing some awesome silicified cyanobacteria fossils and their taphonomic history. #fossils #cyanobacteria #cambrian

I was really impressed. Great optics, nice camera, interfaces well with other devices, good in both transmitted and reflected light.
Yes! I bought the Tomlov one as a present for my Dad. It turned out to be fantastic.
the thing about a publicly funded space program is that you get to be represented by these people as opposed to, say, Jeff Bezos's second wife
Crescent (partially illuminated) Moon and Earth facing the Sun. The Sun is just out of frame to the right leaving flares of light reaching out toward the left. NASA/Artemis II/Kevin M. Gill
This might be one of my favorites from Artemis II. A cinematic alignment of the Moon and Earth, each cradled within the warmth of sunbeams.
Taken from behind the Moon on April 6th.

Anyone else getting strong Croesus-at-the-Oracle-of-Delphi vibes from this statement?
This is the face of a lunar scientist who has just been told that the #Artemis II crew saw SEVERAL impact flashes (the flashes when meteors hit the lunar surface) in real time 😃 🌓💥
This shit again.
Artemis II launch
Away we go! — and what care we
For treasons, tumults, and for wars?
We are as calm in our delight
As is the crescent-Moon so bright
Among the scattered stars
(William Wordsworth, "Peter Bell", 1798)
Then vs now. Such a shame.

Ever wonder where the science landed on bio-signatures on exoplanets? Our @oxfordphysics.bsky.social colleague @astrojake.bsky.social has written up a succinct summary of the drama and what the latest paper adds.
It's a good read!

New 225-m diameter lunar crater imaged by LRO, incidence angle 38°. Image width 950 meters, north is up.
A new 225-meter (740-foot) crater appeared on the Moon while nobody was looking. NASA's lunar orbiter imaged the dramatic aftermath.
Such large impacts are once-in-a-century events. This one happened in the spring of 2024. 🔭🧪

Is it a giant wooden horse
This is... not going to happen
Desert varnish on Mars?
The US is no longer a liberal democracy, according to the top global watchdog on freedom and democracy. We're falling fast, and are now classed the same as Guatemala, Colombia, and Peru

it just occurred to me that let there be light was the first prompt
The Mars Sample Return program - cancelled by the US because of cost overruns - was cheaper than this. Humanity could have brought home the most promising potential signs of life ever found beyond Earth. I guess one way or another we are learning who we are.
Photo of a cuneiform tablet fragment shaped a bit like an irregular diamond. It preserves nearly 20 incomplete lines of text separated by a horizontal ruling
There's a broken cuneiform tablet from the Old Babylonian period, nearly 4,000 years ago, which preserves a tiny portion of a dialogue between two friends.
It feels a bit like the conversations I've been having for the past week, so I wanted to share it.

I don't think this is correct... where did you get it from?
