[...] 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. I don't remember seeing a lot of blue near the Great Red Spot, however. Consider these tips on how to draw Jupiter: https://c02.purpledshu...

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? The massive object distorting the galaxy must be off to the left. And really, what is that orange hamburger-like o...

HST: Close up of the irregular galaxy NGC 4753 NASA/ESA | Original release 2024 May 13 [...] GOTD4Y Jac NGC 4753 looks like a typical lenticular galaxy, with a few elegant strands of dust weaving across the core, as if the clothing of the galaxy has been unraveled and only a few thin strands are le...

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! (...

Is there even a definition of a "bar" based on something other than mere appearance? Is it simply dust/gas that is apparently concentrated more or less predominantly along a line through the galaxy core? Well. When I look at the galaxy in IR, it doesn't remind me much of a bar either. ......

I wonder why does SSDS fish have a collar (just like APOD fish does) and neither GLIMPSE nor SPITZER fish do? Good point. Well I think that since both work in the IR range, the view changes from dark dust clouds to bright warm gas clouds which appear practically equally bright in the front and back...

Once again a masterpiece! Congratulations to the Deep Sky Collective team. Be sure to click twice on the image to see the Nova up close, gorgeous object!

Still not much of a definitive bar in M61 at all compared to your other examples. And I'm not convinced of the "inner" bar in NGC 1365 either! "A bar is in the eye of the beholder" it seems. I just told you that I don't necessarily always trust Wikipedia, but now I'm going to qu...

In context from a wider field of view image at one of the links in the text: fish head, heart, and soul nebulas.jpg I still find the area very exciting even in IR. https://live.staticflickr.com/65535/53692377213_263792ee09_b.jpg jac berne (SSDS/GLIMPSE) https://live.staticflickr.com/65535/536912714...
