Off to #GWPopNext! Will there be as many #GravitationalWave candidates as during #NAM2023? A good start with #S230708cf

If real, its source is probably a binary black hole

What is going on in Venus' atmosphere?

Interesting talk at #NAM2023 from updating us on the discovery of phosphine in Venus’ atmosphere, a chemical which on Earth is produced by life. New observations from JCMT add confidence the discovery is real, though the team are struggling to get time on ALMA, the more sensitive telescope.#astrodon

Nice talk by Lisa Kelsey at #NAM2023 on "Kilonova Seekers", a citizen science project on Zooniverse to enable GOTO to follow up gravitational wave detections with optical searches.

Qs: could rings form?
Qs: what to hit next?

A: material may have got stuck in the system leading to a long-lasting tail. As for next targets: top priority is a search telescope, more kinetic impactors to be decided #NAM2023 #Astronomy #DARTMission #PlanetaryDefense
