Started reading “A Brief History of Black Holes” by Dr. Becky Smethurst. These chapter titles are great 😂

#UMPlus - A Gamma-Ray Pulsar

https://www.universomagico.net/2025/08/un-pulsar-emisor-de-rayos-gamma.html

This fascinating field of view harbors an incredible mystery, invisible to the human eye. It was captured using the OGM spectrograph on the Gemini North telescope in Hawaii. Within this nebulous region, gamma-ray emission is present. PSR J2030+4415 is an extremely dense object left behind by the death of a.....

It is not always easy to find a good fit at an excellent research institution. If you are considering doing a #PhD or #Postdoc in #mathematics #particlephysics#theoreticalphysics or #astrophysics we have you sorted in Hamburg. This workshop is a way to get to know our Cluster of Excellence and #UniHamburg/#DESY groups on those topics, just before we start hiring this year. Check it out!

(14 Jul) Merger of two massive black holes is one for the record books

The event resulted in a new black hole with a mass 225 times larger than our Sun.

💥💥 Double detonation!

For the first time, astronomers have obtained visual evidence that a star met its end by blasting twice.

This was done by studying the centuries-old remains of supernova SNR 0509-67.5 with our Very Large Telescope. Led by the Univ. of South Wales, this shows some of the most important explosions in the Universe in a new light.

What happened exactly? Keep reading.

Chaos, panic, total devastation: #asteroids in films are devastating, and only an unlikely, heroic mission can save humanity.

But what would happen if an #asteroid hurtled towards us for real?

On the occasion of #AsteroidDay, tune in to Chasing Starlight to find out:

💥 What Will the Betelgeuse Supernova Be Like - And Will It Hurt Us? • Universe Today

｢ It will be visible during the day. It will be brighter than any planet. It will be almost as bright as the full moon. You'll be able to read a book by the light of the Betelgeuse supernova at midnight ｣

Hello #FediScience, migrating from astrodon.social (about to close), I am joining you here (inspired by @wolfgangcramer), so it's time for a new #Introduction

I'm Alexandre Santerne (call me Alex), #astronomer working @LAM_Marseille & teaching at Aix-Marseille #University (France).

I'm expert in finding #NoPlanetB 😀 ( #planets around other #stars).

I want to work in a #fair, #inclusive, and #sustainable #research #environment, so I (try to) act accordingly. I'm a member of @labos1point5

I toot a lot about #Astronomy, #Astrophysics, #Space but also a lot about #ClimateChange and #Climate.

Since 2019, I completely boycott planes, and I travel by #train (long distance) and #bike (short distance) as much as I can.

My other interests include #photography (visit my Flickr gallery in my profile) #Astronomy#Space

Oh, in case you don't know where Aix-Marseille is (trick: in 🇫🇷 ), the image below (credit: #NASA / JPL-Caltech / Space Science Institute) is indicating where I am, as seen from #Saturn...

... and where you also are, together with 8B people as part of 2M species 😀

This rare image taken on July 19, 2013, by NASA's Cassini spacecraft has shows Saturn's rings and our planet Earth and its moon in the same frame. At the time, Cassini was 2013 from a distance of about 898.414 million miles (1.445858 billion kilometers) from Earth. It is only one footprint in a mosaic of 33 footprints covering the entire Saturn ring system (including Saturn itself) taken by Cassini's wide-angle camera.
