First images of comet #3I/ATLAS from Europe's Mars orbiters 😍

Observing the comet from 30 million km away, #ExoMars reveals the halo of gas and dust surrounding the comet's nucleus.

Congrats to both of you 👏 🎉

Very nice to see ngGONG move forward! GONG is a decades-old global instrument on which the Sun never sets, to observe the Sun around the clock. It provides very important continuous monitoring of space weather and allows us to image the interior of the star itself. ☀️

“In an anonymous survey of (UK Physics) department heads by the Institute of Physics (IoP), 26% said they faced potential closure of their department within the next two years, while 60% said they expected courses to be reduced.”

We bail out banks. We bail the steel industry, the water industry, airlines and hotels.

The UK higher education sector directly employs nearly 1M people. It's the envy of the world and benefits almost every area of UK society. But apparently it can go burn.
Would be great to have you there if you do 😊
Opening night! 🤩
🌞🎶 Experience the aurora like never before!
Aurora — an immersive exhibition turning May 2024 aurora into sound 🔊
📅 Opens 10 Sept, 5–6.30pm
📍 Gallery North, Northumbria Uni, NE1 8QE

I feel your pain 😅 see you tomorrow!
Brought to you by Sensing Remoteness — a new collective of scientists + artists pushing the boundaries of data + sonification.

Join us 11–17 Sept (weekdays, 11–5).
If you’re in Newcastle, don’t miss it 👉 step into the aurora. ✨
We’ve sonified X-ray, magnetic field + ion flux data from Solar Orbiter, ACE & GOES.
Three sound systems (incl. the incredible IKO ambisonic array) + the gallery itself become a resonant instrument. 🌠🎶

Arrival was last night, did anyone managed to catch the aurora in the UK? Of course I am away at a conference right now… 😅
A bit late to the party 🎉 but it looks like there is a chance for moderate to strong geomagnetic storming (G2/3) due to the arrival of a fast solar eruption expected on Monday/Tuesday. Aurora may be seen in central UK 👀 🌞💨 🌎

This #solarstorm from late Aug 30 2025 will arrive at 🌍 noon to late Monday Sep 1.
Depending on its internal magnetic field, it has the potential for #aurora in central Europe and maybe #GNSS errors.
Parker Solar Probe will tell us in hindsight if its field was predictable from 0.5 au.

🧪 BREAKING (good news): Senate subcommittee says NO! to Trump's proposed slashes to NASA & NSF funding.

Today, the subcommittee said to keep NASA + NSF funding at $33.9 billion, the same as in FY24.

See 7:15 below. Full Senate appropriations committee meets tomorrow about it.

Hopefully it hasn’t jinxed it, but you could announce it after a successful day of sciencing 😂
Don’t advertise it to the Universe!

Solar astronomer @stephyardley.bsky.social joins BBC Science in Action this week to explain why the new polar views of the Sun, from ESA's Solar Orbiter, will make such a difference in unravelling the Sun's magnetic turmoil and what drives the 11-yr cycle in activity.

BBC World Service - Science In Action, The First Solar Polar Pictures
ESA’s Solar Orbiter camera probe begins raising its orbit towards the sun’s poles.
www.bbc.co.uk
I assume it’s related to the logistics of doing that and also that it’s not the entire goal of the mission - which is exploring the connection between the sun and the heliosphere
We now have views of the Sun's poles for the very first time thanks to ESA's Solar Orbiter Mission! This is only the start as Solar Orbiter's inclination will increase to up to 33 degrees out of the ecliptic later in the mission...🌞🛰️
🌞 See the Sun from a whole new angle.

For the first time, our Solar Orbiter mission has captured close-up images of the Sun’s mysterious poles, regions long hidden from our view.

Hey! Lookie what PUNCH (@punch-mission.bsky.social) just saw! Two different solar storms crossing the entire inner solar system! NASA's site doesn't thumbnail well, so click the link for the movie and other images. ☀️🔭🛰️🧪

Inspired by @jtuttlekeane.bsky.social and @ohdearz.bsky.social, here's what the White House proposed budget cuts to NASA would do to the entirety of the agency's Science Mission Directorate.

Bloodbath is right.
