#KnowledgeBit: #Polar #Ring #Galaxies are some of the most spectacular looking galaxies that we can see.

Beyond just being beautiful, they provide important clues about the formation and growth of galaxies over time

The Bubble Nebula - NGC7635 - C11
Imaged in mono, LRGB mostly for stars, the rest is Ha/Oiii/Si.

The Bubble Nebula, catalog NGC7635 and C11, a faint nebula about 11,000 light years away with the appearance of a bubble cause by expanding gases from the central star. Imaged over several nights from Savannah, GA USA using monochrome imaging that isolates the RGB colors and different gas colors with filters. This uses about 12 hours total imaging across the 7 filters. The separate stacks of exposures get combined in post processing. This may get a future edit that could look very different.

Approximately 13.8 billion years ago, the Big Bang is hypothesized to have occurred, kickstarting our universe and eventually life on our small, blue world. While the Big Bang has yet to be directly…

Across ~13,000 galaxies outside rich clusters, links between shape and cosmic-web location weaken at lower stellar mass, though dense regions still differ. An observed correlation, not a proven formation mechanism.

I purchased a ZWO Seestar S50 Pro #smart #telescope a few weeks ago. I've taken advantage of some clear skies to #photograph some #nebula and #galaxies. Being so much easier and faster to set up is huge for taking advantage of an hour or two of clear dark skies.

🔭 Jets light up hidden gas clouds

Astronomers stacking quasar light behind radio galaxies found jets punch through the surrounding gas, lighting up dense pockets invisible to other measurements of the same gas.

MaNGA stellar motions, H I line widths and halo masses suggest less inner dark matter in massive halos than TNG100/EAGLE predict. Follow the mass estimates and their model and sample assumptions.

How does galaxy shape relate to the cosmic web? A COSMOS2020 study separates local density from web distance across stellar masses. Its ~13,000 galaxies span groups and the field, excluding rich clusters.
