Neat new student project - build a CubeSat to monitor in-situ radio frequency interference in orbit!
Requests calls for formation of team that will design, develop, test and submit CubeSat that will conduct in-orbit RFI monitoring.
A tool like this will be very useful in the age of constellations.

Watch Earth’s newest quasi-moon in motion. 🌍🌀
The new paper “Meet Arjuna 2025 PN7” confirms #asteroid 2025 PN7 is trapped in a quasi-satellite orbit, looping around Earth (in a rotating frame) from the 1960s to the 2080s.

A while ago, I wanted to invent a version of 2048 that, instead of numbers, used astronomical objects. Start with small ones eg asteroids, go out to planets, then stars, then constellations, then star clusters, then galaxies etc ...

For Sydney, the eclipse peak will be at 04:11:47 and the Moon will be setting, about 23-degrees above the western horizon.
Not far from it will be Saturn and if you've got a good enough 'scope + camera - Neptune near that.
Best for those who live high up with clear view of west

If you're downunder like me and you want to see the best parts of the eclipse, it's going to be a very early morning (or very late night). The partial eclipse, when the darkest part of Earth's shadow starts crossing the Moon, begins at 2:28am on Monday the 8th of September

The Astronomy Photographer of the Year competition is coming round again and the shortlist is stunning.
See the whole shortlist here: www.rmg.co.uk/whats-... and there will be an exhibition of all of them at Royal Museums Greenwich after the winner is announced.

3I/ATLAS measurement from HST is in: can see the coma but not the nucleus. Sets effective nuclear radius of r < 2.8 km (H>15.4), significantly smaller than earlier estimates (as anticipated).

Today the Space Force cataloged 51 more debris objects from this event. These are not new objects; they likely have been in orbit since 1977 but were too small to be reliably tracked until now. Today's additions push the satellite catalog over the 65000 mark.
