...So, yeah. It's an impressive picture, it really is. And that's all I have to say about it! Ann Personally, I am particularly impressed by the dynamics of the event when you compare it with the size of the Earth. The effective discharge only took about 15 minutes. What tremendous energies and dis...

[...] The purple color of M78 in today's APOD was caused by the artistic choices of the people processing the image.

This galaxy looks very unique to me. I am a student of galaxies, these look brand new to me. There appear to be ~3 rings around NGC 3169 perpendicular to its plane of rotation. Has the other galaxy circled it that many times? I would love to see the simulation of these 2 galaxies interacting. Note,...

So, I'm reading that tiny NGC 3165 is also part of this triple, and at about the same distance, yet it doesn't seem to be interacting with the other two at all, either currently or in the past. Why not? Also, I note that NGC 3165 is classified as a spiral too, which would confirm that spirals reall...

[...] According to this site , both NGC 3169 and NGC 3166 have active black holes, and I have to wonder if the jet-like feature emerging from NGC 3166 is a remnant of an outburst of that galaxy's black hole. [...] Ann I think that the "jet" of NGC 3166 is an arm of NGC 3169 that was stret...

[...] The bluest parts of Jupiter are the bluish festoons, which are seen emerging from the north equatorial belt and protruding into the white equatorial zone.

This system is pretty crazy: Strange early galaxy by JWST in May 2024.png Is the strange (starforming?) galactic arm a tidal feature? If so, something is tugging at this galaxy - what?

If one assumes that, according to theory, every black hole also has an accretion disk... What theory is that? I think the overwhelming majority of black holes in the Universe have no accretion disk. This simulation shows the appearance of a black hole with an accretion disk. Simulations have also b...

On the topic of visualizations, Jean-Pierre Luminet is a French astrophysicist who made this image of a black hole 45 YEARS AGO! The first one ever apparently. Using maths, and a 1970’s computer… He’s still alive and still studying black holes today, he deserves a mention on this black hole week! (...
