Congratulations! (I'm choosing to believe this celebratory happy dancing cat is not in fact AI generated but is in reality an amazingly well trained kitten)

I think you’ve just been pipped at the post I’m afraid

You were the first! Can you DM me an address to send it to?

Is that a yes please?

Wow, that’s wild. And the weird thing is that piling on information in response doesn’t help at all. You can’t help people who don’t want to be helped

Yes we can opt out, but where’s the fun in that? I’d have to buy a diary to give away each year

Many other @ec-euclid.bsky.social papers being released this week, including by Daniela Vergani and team on discoveries of galaxies with unusual emission lines - here's an explainer by @stephenserjeant.bsky.social 🧪🔭
!["Euclid's ability to cover such a large area of sky makes it a marvellous place to find rare objects that often could not be discovered in any other way. Euclid also doesn't just take images; its spectroscopic instrument also splits light up like a rainbow to diagnose how redshifted (how far away) each galaxy is and the conditions inside each galaxy. In this paper [Vergani et al] we used Euclid's spectroscopic instrument to unveil a population of rare galaxies with stronger ionizing radiation inside them, perhaps caused by a curious, unusual history of star formation that's assembling the stellar masses of galaxies. Unpicking this will be the subject of a lot of future research, and this is just the tip of the iceberg of the rare object discoveries awaiting us with Euclid."](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:rqzhexkrr5iazknlluqozsw7/bafkreibxkye62qpn3cwcxxt4z2bk6eq3c5aui4qyw3pz3xckbwunzmmuxq@jpeg)
