#UMPlus - Full View of NGC 7793
https://www.universomagico.net/2025/03/vista-completa-de-ngc-7793.html
NGC 7793 is a spiral galaxy located in the Sculptor constellation and lies at a distance of about 13 million light-years from the Milky Way. It is one of the brightest galaxies in the Sculptor Group, one of the closest galaxy groups to our Local Group. The image shows the spiral arms and a small.....

Am Samstag gibt es eine Sonnenfinsternis. Sagt Meton. Und der muss es wissen.
On this day 16 years ago, our distributed computing project @einsteinathome began searching for radio pulsars for the first time.
Previously, volunteers were able to donate computing time on their computers to search for gravitational waves from rotating neutron stars (still mysterious remnants of exploded stars).
Starting 24 March 2009, new applications were available that allowed Einstein@Home volunteers to search Arecibo radio telescope data for radio pulsars (special neutron stars) in close binary systems.
New JWST image just dropped.
This object is called Herbig-Haro 49/50. It's the outflow of a still-forming star hidden from view to the lower right of the orangish cone of material oriented diagonally in this image.
As stars form they eject excess matter in the direction of their poles of rotation. That material encounters the interstellar medium in the vicinity and lights up in response. "Like the wake of a speeding boat, the bow shocks in this image have an arc-like appearance as the fast-moving jet from the young star slams into the surrounding dust and gas."
Purely by coincidence, the outflow lines up with a distant background galaxy, which is the circular pinkish/blue object at upper left.

Webb unmasks true nature of the Cosmic Tornado
The NASA/ESA/CSA James Webb Space Telescope has captured a beautiful juxtaposition of the nearby protostellar outflow known as Herbig-Haro 49/50 with a perfectly positioned, more distant spiral galaxy.

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 ｣

Postdoctoral positions in Computational Relativistic Astrophysics at our Potsdam institute
The “Computational Relativistic Astrophysics” department at the @mpi_grav in Potsdam led by Masaru Shibata announces the opening of postdoc appointments (2 years).
The department is currently composed of two group leaders, one senior scientist, and several postdoc researchers and students.
It focuses on several research topics in relativistic computational astrophysics including neutron star merger, collapsar, stellar core collapse and explosion, formation of supermassive black holes, and multi-messenger astronomy.

What does it mean to be human? My talk and conversation at Synapse 2025 in New Delhi about black holes, the universe, us, and the divine now on YouTube. I had lots of wonderful discussions afterwards and felt really at home among this crowd. Lots of synergies.

Using ALMA, in which we are a partner, astronomers have found oxygen in the most distant known galaxy!
The galaxy, known as JADES-GS-z14-0, is so far away that we see it as it was when the Universe was less than 300 million years old, about 2% of its present age.
Researchers had thought that this early on the Universe was still too young to have galaxies ripe with heavy elements. Yet this record-breaking detection indicates that JADES-GS-z14-0 has about 10 times more heavy elements than expected, making scientists rethink how quickly galaxies formed in the early Universe.

How will the universe end? A changing understanding of dark energy may provide a new answer.
@AssociatedPress reports: "The big question is whether this dark energy is a constant force, which scientists have long thought, or whether the force is weakening, a surprising wrinkle tentatively proposed last year."
In the old days, we started to get excited when there was a five sigma detection (and probably 7 when you had to compare different experiments with different systematics)
