Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After only a few million years for the most massive stars, the enriched material is blasted back into interstellar space where star formation can begin anew. The expanding debris cloud known as Cassiopeia A is an example of this final phase of the stellar life cycle. Light from the supernova explosion that created this remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light 11,000 years to reach us. This sharp NIRCam image from the James Webb Space Telescope shows the still hot filaments and knots in the supernova remnant. The whitish, smoke-like outer shell of the expanding blast wave is about 20 light-years across. A series of light echoes from the massive star's cataclysmic explosion are also identified in Webb's detailed images of the surrounding interstellar medium.

The amazing @esa.int Gaia telescope is taking its last measurements today

Gaia has had a tremendous impact on astronomy. Without the easy to access (and use) data releases, a lot of the work I do would be impossible

Thank you, Gaia and team! Can't wait for the future data releases! 🔭🧪
Artist's impression of the Gaia space telescope in front of the Milky Way. Gaia looks kind of like a sunhat. I've added a little halo above it. The Milky Way has a glowy centre and you can see the dusk tracks in the disk. You can also see the bright blobs of the Magellanic Clouds below the Milky Way

The Pasadena street we lived on till just a few months ago is under evacuation. Our neighbors have left with pets. This was unfathomable a few years ago. We thought being 5 mi from foothills meant it has to be an insane wildfire far in the future of climate change for our area to evac.

Haven't had the opportunity to image the sky for a while due to cloud and the festive period. I'm getting withdrawal symptoms!

This image of the Tadpoles Nebula is from the end of last year. It's processed using a false Hubble style palette.

The geometry of this "Poincaré disk" inspired M.C. Escher's "Circle Limit" series of drawings. In this case the rulers are the fish-lengths. See how they get small as you approach the edge? (21/n)

Image: M.C. Escher, "Circle Limit III"
A color image of M.C. Escher's drawing "Circle Limit III." It is a map of the Lobachevsky upper half plane to a disk. The semi-circle geodesics are now arcs between points on the edge of the circle. A number of colored fish are drawn along these arcs; all the fish along an arc have the same color. They are longer near the center of the disk and shorter near its edge.

57 years ago today, Jocelyn Bell detected a series of strange, repeating radio signals. Her finding led to the discovery of pulsars...and inspired the iconic cover of Joy Division's first album. 🧪

Next week over 250 astronomers gather in Boston to celebrate 25 years of NASA's flagship X-ray mission Chandra.

Planning this event over the last year as the SOC and LOC lead has been such a tremendous learning opportunity and a privilege. Fingers crossed it all goes well 🤞

This is such a wonderful news for the X-ray community!

From Athena's social:

"ESA's Programme Committee endorsed a rescoped version of the Athena mission. The SPC has recognized that NewAthena will transform our knowledge in almost every corner of modern astrophysics"

Excellent news about Athena, as the ESA SPC formally endorsed the re-scoped mission. The Athena X-ray observatory is a vital part of the astrophysics landscape going forward, for understanding everything from supermassive black holes and giant clusters, to galaxy formation, and stars and planets.

Some, as they say, personal news. Relevant for astronomers 🔭 and anyone who does citizen science with Zooniverse. 🧪
A note from Chris Lintott
For more than a decade, I've been ending talks by looking forward to the rich data that will soon begin flowing from the Vera Rubin Observatory. The observatory's magnificent new telescope, nearing it...

First post here! Check out this feature by AAS Nova on my first first-author paper from my master project to know more about ultra-stripped supernovae and how they are related to binary neutron star mergers 👀 https://aasnova.org/2023/08/09/lost-gravitational-wave-source-gained-sn2019wxt/
How We Lost a Gravitational Wave Source and Gained a Supernova - AAS Nova
The hunt for the source of a gravitational wave signal came up short, but it revealed SN2019wxt: a supernova with a curious light curve.

Whoaa! AAS Nova featured our recent discovery of a super cool ultra-stripped supernova found during follow-up of a LIGO event.

The lead author is Hinna Shivkumar. It was so much fun to help her through her first paper!
