In a few hours in some areas of the world, interstellar visitor 3I/Atlas is going to be occluded by the moon. Interesting unique (and challenging) shooting opportunity, astrophotographers out there? 🔭🧪

I produced with my colleagues at @eso.org a new episode of our Chasing Starlight series about 3I/Atlas, where we interviewed comet specialist Cyrielle Opitom #astronomy 🔭 🧪
The interstellar visitor 3I/ATLAS ☄️ cruising through our Solar System is no alien spaceship and won't hit Earth.
Still, the buzz around it is far from unfounded 🤩

Whooooaaaa, this is extremely neat!
And spectropolarimetry (which is the best, and what we used in my first paper too!) is at its core 💙
In a nutshell: astronomers used the polarization of light to study the shape of a supernova explosion before it interacted with surrounding material.

For the first time ever, astronomers have unveiled the shape of a supernova explosion just a day after detection, as the blast was breaking through the star’s surface.
Achieved by our VLT, this feat will help us understand how massive stars die: https://www.eso.org/public/news/eso2520/

Groundbreaking new image! The EHT reveals the dynamic environment around black hole M87*.
The 2021 image shows a distinct shift in polarization patterns, tracing changes in magnetic fields near the event horizon.

Our VLT has found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars.
This is the first time we have strong evidence for one of these ‘polar planets’ orbiting a stellar pair 😲

Bathed in the sunset light, this image shows steady progress in the construction of ESO’s ELT!
At first glance, the steel structure might look modest in size, but it's already more than 50 metres high and 41 metres wide 🤯

If you're mad and find yourself yelling that you want someone launched into the Sun, take a moment, calm yourself, and remember that it takes a lot less Delta v to launch them out of the Solar System instead.
You can be mad, but that's no excuse to be inefficient with propellant.
