I still think they should build out a lunar crater radio telescope out there on the dark side of the moon. The radio silence and scale would be impossible to get any other way.
That’s an interesting thought I hadn’t considered. The Webb is about as quiet as we’re going to get anywhere near our orbit, but a lunar compound could very easily be much larger, and would be a great deal easier to service/upgrade.
Astronomy is constantly discovering never-befor observed phenomenon. The idea that you can simulate realistic images of anything requires you to have sufficient knowledge of reality, and astronomy keeps showing us that we don’t have that.
The only way I can see this being helpful is to train algorithms for what is already known and can be safely filtered out, making it easier to detect new observations
Neat to see a 6-7 solar mass black hole spotted. First one without a companion star to give it away! As we get better at finding black holes of this size, will be interesting to see if they end up explaining part of the “dark matter” problem.
Astronomers have generally thought that massive black holes at the centers of galaxies expel gas in jets of material only during their formative years, when the central black hole is gobbling up gas and stars and producing lots of radiation. This makes them stand out as what astronomers call active galactic nuclei (AGN), or quasars.
If, as the new study suggests, the ionized hydrogen halo around galaxies is more diffuse, but also more extensive, than thought, this implies that the central black holes may actually become active at other times in their lives.
I love how we keep finding more and more about the role that black holes play in our universe.
