It’s time to begin a new mini-series. And today @AstronomyCast start with the dwarf galaxies, which flock around larger galaxies like the Milky Way. Are they the building blocks for modern structures?

Sep 13th: Milky Way’s Stellar Streams Highlight Dark Matter
Recent observations of twelve different stellar streams around the Milky Way have revealed the effects of dark matter, similar to how lights on a Christmas Tree reveal the shape of the tree in dark.
Jun 5th: Too Big, Too Soon: Massive Early Galaxies Defy Expectations
One of JWST’s top jobs is to peer deeper into the Universe than ever before, watching as the first galaxies came together. What’s going on and what does it mean for cosmology?
Apr 15th: Physicists Hunt for a Mirror Universe Galaxy
Is the many-worlds interpretation of quantum mechanics science? While we may not be able to say what exactly science is, I can say that I prefer to have my science with a little bit of data. For me to recognize science when I see it, it has to come with some observations or something verifiable
Apr 8th: Galactic Immigration In The Andromeda Galaxy
Galaxies grow through mergers with other galaxies. Using the Dark Energy Spectroscopic Instrument (DESI) astronomers have studied the merger history of the Andromeda Galaxy for the first time. So today we will learn about the immigration history of the Andromeda Galaxy.
Feb 25th: How to Train Your Galaxy
Today @cosmicsavannah discus about how to recreate the formation of galaxies inside a supercomputer with Dr. Rob Yates as he explains how he uses semi-analytic simulations to try and understand how various elements are created and dispersed around galaxies.
Feb 18th: The Cartwheel Galaxy From the Webb Space Telescope
NASA’s James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation and the galaxy’s central black hole. Webb’s powerful infrared gaze produced this detailed image of the Cartwheel and two smaller companion galaxies against a backdrop of many other galaxies. This image provides a new view of how the Cartwheel Galaxy has changed over billions of years.
Feb 8th: AI Reveals Black Holes and Galaxies Grow up Together
Astronomers recently found that the growth of a galaxy and the growth of the supermassive black hole, or SMBH, at its center have a lot in common.
Dec 9th: The Science of the L1527 “Butterfly” with Dr. Karl Stapelfeldt
Time for weekly news with @WSHCrew about Artemis 1, asymmetry in galaxy distribution, Mars occultation by Moon, gamma ray burst, and discussion with Dr. Karl Stapelfeldt about the science of hourglass/butterfly of L1527 amazing structured.
Sep 7th: Explosions Help Us Measure Distances in the Universe
How do astronomers measure extremely large distances in the far away corners of the Universe? So this would be the top step on the cosmic distance ladder.
