New in @nature.com : Using #NASA 's Juno and JEDI instrument from @jhuapl.bsky.social we show Jupiter's foreshock accelerates electrons to near light speed. Using our solar system observations, we built a scaling law from planetary shocks to supernova remnants. www.nature.com/articles/s41...

Relativistic electron acceleration at the bow shock of Jupiter and beyond - Nature

NASA’s Juno observations show relativistic electron acceleration at the bow shock of Jupiter and establish a universal scaling law linking shock size to maximum cosmic ray energy.

🚢 Inspector Smile has begun a two-week voyage across the Atlantic, heading for Europe’s Spaceport in French Guiana. In the early hours of 11 February, Smile left ESA’s technical heart by truck for the Port of Amsterdam, where it was loaded onto the cargo ship MN Colibri. 🔭 🧪

Bird of the Year voting opens tomorrow, and it is an outrage the takahē is yet to win. I'd like to take this opportunity to urge you to vote for the hide-and-seek legend from Fiordland, the roundest birb, and the one true pick for all you railfans out there

André Brett@drdrehistorian.bsky.social · 2y ago

It’s Bird of the Year time, and the official railfan option is the MIGHTY TAKAHĒ, the largest living member of the rail family of birds So when you vote, don’t forget to include the takahē in your top five: birdoftheyear.org.nz

A takahē looking especially giant and round, blue and green like a globe with a beak

AGU is deeply disappointed in SCOTUS decision to overrule the order blocking the dismantling of fed agencies until we could make our case about the President’s unlawful actions.  The harm this will cause is shocking. However, we will continue to fight for the rule of law.

NASA Goddard is pushing through a 48% staff reduction!!! This could impact the upcoming Roman Space Telescope and many other future Astro missions. News coverage seems not sensational enough. Are we really going to let NASA (as we know it) die quietly? www.space.com/space-explor...

NASA begins push to slash workforce with more staff buyouts, early retirements as budget cuts loom

NASA employees have until July 25 to decide if they'll stay or go.

Today I gave a seminar on the topic of my doctoral dissertation, and with that, I have now completed all of my doctoral studies. ... Aside from the thesis. Still gotta finish writing that. And then defend it.
