"'It’s difficult to say exactly how many asteroids will be lost… but preliminary results suggest that for every five near-Earth asteroids we discover, we lose one solely due to constellation interference. That’s if no mitigation measures are taken.'"
The Sun emitted a strong solar flare, which peaked at 6:54 am UT on May 10, 2024. The Solar Dynamics Observatory, which observes the Sun constantly, captured an image of this event, as seen in the bright flash towards the center of the image. Solar flares are powerful explosions of energy that can affect radio communications, electrical power grids, navigation signals and..... #astronomy#space#astrophysics#astrophotography

Today's distraction from my work: the results of the Royal Astronomical Society's Bullying and Harassment Survey. It's not good. Or surprising.
"[The] survey... showed that disabled people, women, Black and minority ethnic, and LGBTQ+ people are much more likely to be bullied and harassed than men and White, straight, and non-disabled people.
...Two-thirds of respondents who reported complaints felt their concerns had been handled inadequately."
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) #astrodon#academicchatter#astronomy
A two panel mosaic of our central star in H-alpha light ☀️
I really wanted to try the Daystar Quark from my local astronomy club and this is one of the first proper images that came out of this session.
Have gone trough quite a lot of iterations in post processing, because I could not understand what was missing... now I know, it was the crazy "inverted" color palette.
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.
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..... #astronomy#space#astrophysics#astrophotography
i also managed to image this afternoon's ISS solar transit using my Hydrogen Alpha Telescope. The detail on the solar disk is fascinating! #ISS#spacestation#astronomy
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.
Who says you cannot shoot dark nebulae from the city? This is LDN694, one of my most beloved targets. A copious star field just barely blocked by a dark nebula which resembles a void.
