Picture of the day: This wild-looking supernova remnant is nicknamed the Jellyfish Nebula. Supernovas produce some of the strangest objects in the night sky.
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..... #astronomy#space#astrophysics#astrophotography
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.
The International Astronomical Union (#IAU) are hosting an #astrophotography gallery in #VR! The event is on May 27 from 11am - 12:30pm UTC and May 28 from 8pm - 9:30pm UTC, and showcases astronomical photographs captured with a smartphone 📱🌌
The event is being held in spatial.io, which is accessible from a VR headset (Quest), or just from your computer browser (i.e. no headset needed).
Das sind die Nordamerika (links) und Pelikan Nebel (rechts) im Sternbild Cygnus. Getrennt werden die beiden Emissionsnebel durch die so genannte "Great Wall", eine gigantische Staubwolke.
Die Aufnahme ist als HOO Variante entwickelt, also als Falschfarbendarstellung, um die Verteilung der verschiedenen Gasgebiete zu zeigen.
ESO 593-8 is a stunning pair of interacting galaxies with a feather-shaped galaxy crossing the companion galaxy. This spectacular galactic dance was nicknamed by astronomers as The Bird, due to its shape in old images. It is likely that in the future the two components will merge to form a single galaxy. The couple is adorned with several star clusters of..... #astronomy#space#astrophysics#astrophotography
While we were all oohing and aahing over the Southern Lights on Saturday night I had my trusty Dwarfii with me. We'd been joined by a middle aged lady with a cellphone and enthusiasm but no knowledge, so between Aurora visits I cast about for an interesting galaxy to show her.
Rob suggested Centaurus A. This amazing celestial spectacle might be a spiral galaxy colliding with a larger elliptical galaxy, and there's a relativistic jet emitting from the supermassive black hole in the middle of it - heady stuff.
What is known for certain, from the party observing on Saturday night was that it looks a lot more like a hamburger than the galaxy nicknamed the Hamburger Galaxy ( NGC 3628 looks more like a hotdog to me) - specifically something from the Hungry Jack's / Burger King stable.
So I'm going to call it the Aussieburger Galaxy. It's possible that the supermassive black hole is the beetroot. We could definitely see the sesame seeds and the pickles.
This image is less than 200 frames, but with a bit of tweaking in Google photos it's acceptable viewing, and a bit of fun. I think the cloud coming in might have halted my stacking. I'd like to revisit this one again soon.
And the nice lady who'd wandered down to get a shot of the aurora with her old iphone? With the help of some advice and my monopod she caught it, and apparently is all fired up to get a Dwarfii of her own, and we have already set a stardate with her this week. Lovely!
The Aurora from Washington, from a star party in Duval.
It started a bit slow, but then we had this moment where it became incredibly bright & lit up the entire sky. At that moment everyone started cheering together, it was an amazing shared experience.
This turbulent and threatening structure is CG4, a cometary globule that seems to want to eat the galaxy ESO 257-19, but it is much further away. How these objects acquire their particular shape remains a topic of debate among astronomers. The characteristics that classify CG4 as a cometary globule are distinguished in this image captured by the..... #astronomy#space#astrophysics#astrophotography
Like many photographers around the world, I went on a last-ditch aurora chase on the weekend of 11 May. The huge CMEs left us with hopes of a second night of Southern Lights at low latitudes
Sadly, it was not to be. But I was determined to not come away from the adventure empty handed, and got this nice shot of the Milky Way.
Aurora Australis, from Shelly Beach at Port MacDonnell, South Australia. Cheeky five hour drive to catch this and so worth it - absolutely breathtaking to see those beams towering over me. Experience of a lifetime.
Sh2-114, also cataloged as LBN 347, is a very faint emission nebula visible in the Cygnus constellation, embedded in a much larger structure cataloged as LBN 346. This bundle of filaments seen here in a detailed wide-field image, collaboration between astronomers Tom Masterson and Kim Quick, are known as the Flying Dragon Nebula. It is a cloud that has..... #astronomy#space#astrophysics#astrophotography
Seeing the northern lights with my own eyes was an amazing experience this weekend! I wrote up a blog post about it and assembled a new video. Check it out!
