Should we try to communicate with aliens?
Many experts think intelligent life is likely to exist elsewhere in the Universe. Should we try to connect with them?

One of the worst reference letter submitting experiences is with the International Max Planck Research School on Astrophysics. They ask you absurd questions outside of just uploading your letter, such as asking for arbitrary rankings of the student. There is no clarity how such information is used.

Check out this awesome work by Ben and his team! Really amazing stuff they can pull out of James Webb
Thrilled to have two years' of work out, in a pair of papers led by @gradientrider.bsky.social and @maxecharles.bsky.social.
We've built a data-driven calibration of the James Webb Interferometer to near its fundamental limits for high-res imaging - explainer at @aunz.theconversation.com!

It would be absolutely awesome if Australia formally joined Horizon Europe. I am sure we would get more back than we put in based on the calibre of scientists in the country.
The Australian Academy of Science welcomes the announcement that the Australian Government has started exploratory talks on Australia’s possible association to Horizon Europe. Learn more: www.science.org.au/news-and-eve...

I am enjoying learning about all things that go *bang* in the radio sky in Sydney this week. Thanks Dougal, Tara and team for organising!
In the middle of a week of interesting talks on radio transients at Dynamic Radio Sky 2025.
Is great to welcome so many people to @sydney.edu.au and @ozgrav.bsky.social for our meeting - and particularly all postdoctoral reseachers and PhD students.

What an amazing image and a fantastic result by @astroryan.bsky.social. This JWST image casts a completely new light on the first image we made of this star in 2019 with @eso.org's VLT. Well done Ryan and team!
