Still seems hard to believe that the energy released can beat fusion. I wonder what percent of the infalling matter's mass gets converted to energy in the accretion disk. Or is that not happening at all and all the energy ultimately coming from the change in gravitational potential energy? (Hmm, I ...

The word “intervening universe” here is the same meaning of "intervening galaxy" or it's the late period of universe from a timeline perspective? Anyone please explain me more information about this term "intervening universe", I am a bit confused here, thanks. I take it to be a...

See that big gap between the larger galaxy's inner and outer arms? It makes sense to me that something may have passed through that gap to widen it. My guess is that this is what astronomers think. My guess is that most astronomers think that these relatively undisturbed galaxies are simply passing...

Yeah. Now why exactly is that? At least one crater still does have very prominent rays, so why don't all of them? And another stark difference is the absence of edge bumpiness on this "terminator moon". Again, why? <<The opposition surge (sometimes known as the opposition effect, oppositi...

I was surprised that solar storms could cause satellites to fall out of obtaining orbit ! It was a consequence of the method they use, which is to release the constellation into a very low orbit (which would be short-lived even without an increase in solar activity) and then boost them up, individu...

https://upload.wikimedia.org/wikipedia/commons/0/04/IC342_RGB2.jpg Take a look at the picture of IC 342 by Sean Curry. As you can see, the core of the galaxy is bright and overexposed, and we can't see any details in it. (But we can indeed see that there appears to be star formation in the bar to t...

Very nice, it certainly does bring out some of the features. On the other hand, it reduced the visibility of rays. To the point that I'm like "Where's Tycho?" Yeah. Now why exactly is that? At least one crater still does have very prominent rays, so why don't all of them? And another star...

By looking at the number of craters, can it be determined from which directions the Moon was struck? It has been struck uniformly. There is no preferred direction. https://upload.wikimedia.org/wikipedia/commons/8/89/14-236-LunarGrailMission-OceanusProcellarum-Rifts-Overall-20141001.jpg <<Oceanus Pr...

I spotted a light in the uninhabited South Sandwich Islands, which seemed unlikely. A quick check and the fact that the image dates from 2016 confirmed what it must be: the erupting volcano Havfruen Peak on Bristol Island as it did erupt that year. How about " Mount Sourabaya , a cone near the...

is it just me or is there really a bar in the core? But it actually looks more impressive in infrared light! Here you can also see the bar very clearly. Agreed, in IR it's much more apparent that there's some bar structure there. https://upload.wikimedia.org/wikipedia/commons/f/f7/Hubble%27s_Hidden...

The enemy of stellar collapse is angular momentum ! One might assume that: 1) stars with the most angular momentum will also collapse the slowest and, hence, allow more time for stellar magnetic fields to escape/reconnect during the collapse process; 2) while stars with the least angular momentum w...

Since NGC 4561 is 50 million light years distant, and thus as seen 50 million light years ago, can we assume that the integration of the two galaxies has taken place?

NO. Galactic collision relaxation times would probably be on the order of a few billion years.
