The astronomy and space news at phys.org over the past few weeks has been so awesome, recommended to anyone interested in these topics. https://phys.org/space-news/ Please Register or Log in to view the hidden image!
Because you have been following the astronomy news lately, that doesn't mean everyone has been. But I do understand why you didn't figure that...
Look, if you want to raise a topic for discussion, do it. But don't just tell us to go and look something up, to see what is, or isn't, happening. That's just dumb.
There is a fascinating article in a women's magazine you might not have noticed "How the colour of your nail polish on your toenails can affect your sex life" https://toenailpolishimportantinfo/yaright/ awesome, recommended to anyone interested in these topics.

I didn't tell you to look anything up. Merely suggested that there has been some interesting developments lately that are worth knowing about if you interested. I raised millions of topics to discuss. You are not worthy of discussing anything with... Expired chemist?
Colour - natural although the two big toes currently natural is bruised colour Broken link - magazine out of business. Something about to many stupid articles Please Register or Log in to view the hidden image!
You see phy.org is still in business? probably got something to do with too many interesting articles, especially the recent ones I find. Do you like any of the recent astronomy articles?
That may very well true However I have a wide range of interest and I am guessing, like many (most) on the net, are bombarded with "look at me" postings Astronomy itself has many facets Don't think a science forum needs reminding ANY site connect with space will (would) have awesome articles Perhaps a bit more detail ie - note the latest details about Dark Energy - might help a person who has a interest in Dark Energy Or if you have a interest in Micro Asteroids start a thread with that as title This thread could be just look at me links ie to generalised Needs a more focused subject (probably not toenails Please Register or Log in to view the hidden image! ) Please Register or Log in to view the hidden image!
offered IMHO: a far better site for just space and astronomy news would be Universe today: https://www.universetoday.com/ joining the site gives you access to news as well as the potential to be involved with not only Fraser Cain's video production but the interviews, guest appearances, and much more. You can join the Weekly Space Hangout with like minded people who help produce the show and have the ability to chat (like on slack.com) with several PhD's helping explain the astrophysics or science behind what is happening (Dr. Pam, Dr. Matt, Dr. Sutter, Dr. Cartier, etc). Moreover, you can also hit up https://cosmoquest.org/x/ and actually participate in citizen science with Dr. Pam et al if you like more than just astronomy and space, check out https://www.sciencedaily.com enjoy
Thank you for posting that, BdS. I don't really understand why some people here might want to flame you for sharing something that you like, think is valuable, and think that others might like too. I see that as a good thing and again thank you for it. This board would be a better place is it included less personality-battles and divisive moralizing, and more directions to stimulating and free educational material. A website that I like and recommend for discussion of spacecraft engineering (as opposed to astronomy per se) is Tim Dodd's "Everyday Astronaut" website. He makes videos explaining various aspects of "rocket science" that are understandable by laymen. Tim's making quite a reputation for himself with his videos, he recently scored a 15 minute one-on-one interview with Jim Bridenstine, the NASA Administrator, and earlier a similar one-on-one interview with Elon Musk. (Both of whom are fans of his site.) https://everydayastronaut.com/ An example is his discussion of SpaceX's Raptor engine, which necessarily includes a little primer on how various representative rocket engines work, their fuel flow cycles, pressures, temperatures and pump arrangements. (Do you know what a "preburner" is?) https://everydayastronaut.com/raptor-engine/ Please Register or Log in to view the hidden image!
offered IMHO only: it's most likely because of where it is posted: > Astronomy, Exobiology, & Cosmology and let's not forget trolling ... I don't know if you have it or not but here are two links to some free educational material: https://ocw.mit.edu/courses/find-by-topic/ http://www.iop.org/
Here's something kind of interesting from Phys.org's astronomy and space news: A group of Japanese astrophysicists think that it's possible for planets to form not only in stellar accretion disks, but in black-hole accretion disks as well, including the super-massive black holes at the center of galaxies, which may play host to really huge planetary systems. Since the inner reaches of these accretion disks would be extremely energetic, it's hypothesized that these proposed planets might be distant, parsecs out from the black hole. And it's speculated that a single super-massive black hole might have lots of these planets. They say: "Planetary systems are ubiquitous -- more than four thousand exoplanets have been discovered thus far. However, proplanetary disks around stars may not be the only site for planet formation in the universe. Here we propose a new site of "planet" formation: the circumnuclear disk around supermassive plack holes (SMBHs)." But they also say... "Observing planets around SMBHs should be challenging. The standard techniques to detect exoplanets around stars, i.e., Doppler spectroscopy, transit photometry, gravitational micro-lensing, or direct imaging are hopeless. Photometry by a hard X-ray interferometer in space might be a possible solution, but the occultation of the accretion disk by the "planets" would be hard to distinguish from the intrinsic time variability of AGNs. The other, indirect way is detecting spectral changes in the mm-wave length due to opacity variation associated with the dust growth as used in protoplanetary disk." https://phys.org/news/2019-11-planets-black-hole-possibility-bizarre.html The abstract https://arxiv.org/abs/1909.06748 The paper: https://arxiv.org/pdf/1909.06748.pdf Listen up, Science Fiction writers!

They are the largest known gravitationally bound structures in the universe, and could serve as excellent laboratories for studying galaxy evolution and cosmology." Do all the galaxies in the cluster orbit each other, is that how they are bound to the cluster? or do they all orbit a common center?
