A mind-blower for a Friday evening:

This deceptively simple-looking graph is a spectrum of gravitational waves ringing through the Milky Way.

The waves may be caused by a chorus of supermassive black holes colliding all across the universe. Whoa!

A decade-long effort to build a machine to unlock the promise of nuclear fusion fell victim to budget constraints and competing science, and was shut down the day it was dedicated. It was never turned on.

Uh oh. The ambitious European-Japanese BepiColombo mission to Mercury has experienced a worrisome "glitch" in its thrusters.

Engineers are scrambling for a fix so the spacecraft can enter orbit around Mercury late next year, as planned.

BepiColombo got some enticing previews of Mercury during its 2021 flyby of the planet.

These images come from the spacecraft's little monitoring camera. The real ones (assuming the spacecraft pulls through) will be far more spectacular.

in 1902.

Greek archaeologist Valerios Stais discovers the Antikythera mechanism, an ancient mechanical analog computer.

The mechanism is composed of at least 30 bronze gears housed in a wooden frame. It features dials, pointers, and inscriptions that correspond to various astronomical cycles. The front dial is believed to show the zodiac and the solar and lunar calendars, while the back dials include the Metonic, Saros & Callippic cycles.

Today in my Astro Sci-Comm class we tried something new: we watched clips of 4 astronomers, & discussed the wildly different speaking/presenting styles. Of course I chose these to be VERY different in style. Only 1 was a chaotic train wreck (spoiler, it was me from +10yrs ago)

I feel like all that time I’ve been practicing shading is starting to pay off.

Sitting atop a fractal surface of black holes, Tribert tries to make Adenine, one of the molecules in DNA, but he didn’t get it quite right, probably because he got distracted by the cats. Maybe next time, Tribert.

After years of searching, astronomers have finally detected an atmosphere on a rocky planet around another star.

But what a strange planet it is! 55 Cancri e seems to be blanketed in carbon dioxide gas bubbling out of a global ocean of lava. Like an image out of Dante's Inferno.

- Holmberg IX

https://www.universomagico.net/2024/05/holmberg-ix.html

This scattered collection of stars is actually an irregular dwarf galaxy called Holmberg IX. It resides just off the outer edge of Messier 81, a large spiral galaxy located 11.8 million light years from the Milky Way and located in the direction of the Ursa Major constellation. This image taken by the Space Telescope shows that Holmberg IX belongs to a type of.....

Astronomers discover new Earth-sized world orbiting an ultra-cool star

https://phys.org/news/2024-05-astronomers-earth-sized-world-orbiting.html

"Next steps for the project could include follow-up observations by the James Webb Space Telescope, which would deliver important insights into the planet's surface mineralogy, and the potential for an atmosphere."

I predict the next big cult of the Sun will be started by radio astronomers, whose life has become way too much dependent on the cycles of solar activity these days.
Human sacrifices of post-docs and phd will be the next step I guess. 😬

#UMPlus - Barnard 344 by Lóránd Fenyes

https://www.universomagico.net/2024/05/barnard-344-por-lorand-fenyes.html

The image by astronomer Lóránd Fényes shows the dark cloud Barnard 344, which lies ahead of a larger complex called the Gamma Cygni Nebula, to which it is closely related. Dark clouds like Barnard 344 become visible when in front of bright objects, such as emission nebulae or dense star fields. These clouds contain a large amount of dust and.....

"While there are still hurdles to overcome and challenges to solve before LSST can deliver on its extraordinary promises, thankfully, dealing with tiny bits of space junk likely won’t be one of them."

https://aasnova.org/2024/05/15/huge-survey-vs-tiny-space-junk/

(There's always a "yes, but".)

Yes, but: those tiny bits of debris contribute most to an expected rise in diffuse night sky brightness for ALL observatories.

Hier ist ein Vergleich von gestackten Bildern, die ich von M101 mit meinem #EvoGuide 50ED und #SkyWatcher Az-GTi aufgenommen habe.
Das erste Bild wurde letztes Jahr im Juli mit einer ASI224MC aufgenommen. Es ist ein Stack von 2550 Bildern mit jeweils 3s Belichtung, insgesamt 7650s.
Obwohl es letzte Nacht windig war, konnte ich 50 Bilder mit 120s Belichtungszeit aufnehmen (6000s Gesamtbelichtungszeit). Diesmal wurde eine ASI533MC-Pro verwendet.

Today's H-alpha in good seeing conditions at 17:00 UTC.

There are not many days on which H-alpha views of the Sun include prominences that visualize the magnetic field lines above active regions particularly well, but today is definitely one of those days.

A pseudo-coronographic image of the limb of the Sun in the light of hydrogen alpha showing prominences extending above the solar limb in bright red hues. The solar disc is rendered artificially black. The prominence shown here curls around the magnetic field lines of an active region just beyond the solar limb, forming open and closed loops.
