Porphyrion - record-breaking plasma jet streams, measuring about 23 million light years from end to end (140 times the length of our entire galaxy), ejected from a black hole in a galaxy 7.5 billion light years away. Their ejection began when the universe was half the age it is now; their discovery was announced today in an article in Nature Magazine, spotted by the Low-Frequency Array telescope network.

Universe has some incredible things in it.

[sundowngroup]

Who else is a part of this group, anyway?

BBH: That's actually a very good question!

BBH: Working off the assumption that absolutely *nobody* out there knows who we are...

BBH: There's myself, of course. I'm the senior of the Sundown Group. Then there's my own senior Flocks to the South, who... I will spare you the details on her fate. She is no longer with us. She never was.

BBH: Then we have Bolides Ejecta Anisotropy, a nearby botanical facility situated within a dense rain forest. They're my closest friend in my group, and they currently host a large population of scavengers. The largest I've ever seen or heard of!

BBH: After them, there's Looping Curiosity, who...

BBH: ...

BBH: Actually, I don't remember what Looping Curiosity did while our creators were around! What I do know is that he suffered an injury that permanently damaged his systems, so his memory isn't fantastic. But that's alright. My own memory isn't what it used to be either.

BBH: Ahem. Then there's Ultraviolet Eclipses, who... I believe was a communications hub in her prime? I'm not sure. They've never told me. I'm not especially close with it, you see.

BBH: After that is Voice of Silence. She's a rather unique case in our group. There's some kind of error with her voice, limiting her to only a few words for every spoken sentence.

BBH: I think that's everyone! I hope that one day I'll be able to open up this relay to them so they can speak to outsiders as well!

Physics-based Modeling and Tool Development for the Characterization and Uncertainty Quantification of Crater Formation and Ejecta Dynamics due to Plume-surface Interaction

David Scarborough Auburn University Professor Scarborough will develop and implement tools to extract critical data from experimental measurements of plume surface interaction (PSI) to identify and classify dominant regimes, develop physics-based, semi-empirical models to predict the PSI phenomena, and quantify the uncertainties. The team will adapt and apply state-of-the-art image processing techniques such as edge […] from NASA https://ift.tt/CkO8VA9

Actually, the fact that Mars is still orbiting safely over here means that it was technically an *Euler* apocalypse, not a Venn one.

Impact crater on Mars

In the southern highlands of Mars, CaSSIS spotted ancient and eroded craters filled with sediment. This is the case of this relatively old, 15 km diameter crater in Tyrrhena Terra, showing its age in its flattened rim – younger craters have sharper, more defined rims – and the degraded ejecta blanket.

There is a central uplift section to the crater, as well as many smaller craters, which also suggests an advanced age.

Beautiful dark dunes appear in contrast with wind-blown, pinkish ripples winding their way around the terrain.

Like most CaSSIS imagery, the colours in this image are stretched to highlight the diversity of surface composition.
