Regulus, the pendulum, and a supermassive black hole in Leo I dwarf galaxy

Earlier we wrote about the famous double star Regulus (Alpha Leonis), and why it is known as the 'Pendulum' by amateur astronomers, as well as the small Milky Way satellite galaxy Leo I in the same field of view:

Now the really interesting news is that Leo I seems to harbour a supermassive black hole. This really turns everything upside down about what we understood of galaxy evolution. Which is that in principle, all galaxies have a massive black hole in their centre. They evolve and grow together. Small galaxy - small black hole, large galaxy - large black hole! Well, apparently not:

Or, see a short YouTube video here:

Our image is not great, it was made with a small telescope in our backyard from a town, during full moon. But the story makes it worth posting here. (And PlateSolve tells me we have yet another galaxy in the image, IC 591!)

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
