If I understood this correctly, they analyzed incredibly blurry images and concluded that there are clouds of gas around galaxies, then they extrapolated the found gas up to all or almost all galaxies and concluded that it can fulfill the calculated expectations.
What I understood is kind of the opposite–they already knew there were hidrogene clouds around galaxies but analyzed some almost imperceptibly blurry images and found they were bigger than currently thought. They're blurry because they were taken in some wavelength not observable until now that is scattered by the ionized gas.
Seems like you’re on the west coast (USA). Me too.
I’m hoping I get to duck out for a bit and take it all in after bedtime and chores. I won’t be able to pull out a telescope tonight, but sometimes binoculars surprise me.
You probably won’t see much in terms of globular clusters in binos. I feel like you should be able to resolve the Leo triplet in them, though I expect it would be a challenge. Probably your best bet is the beehive cluster in Cancer, which should be near the Zenith, the little beehive cluster in Canis Major, and some of the easier double stars (the second star out from the cup on the handle of the big dipper- mizar and alcor- is great) and the Orion belt stars. Good luck!
Wow, I never see NGC 4945 pop up in the news, science or otherwise. I looked at it as part of my undergraduate thesis 20 years ago, so I’m always keeping an eye out for it, and almost every time I get a ping it turns out to be M88 or the Sculptor galaxy.
Hi there! For a beginner-friendly telescope under $200 that’s great for nebulae and galaxies in a Bortle class 3 sky, I’d recommend checking out the award-winning options from TelescopeAdvisor. The 2025 Telescope Advisor Awards highlight some fantastic manual scopes perfect for your needs—no smartphone apps required! Something like a 4.5-inch or 5-inch reflector with decent magnification could be ideal for spotting deep-sky objects in Southern California’s rural skies. Visit Award Winning Telescopes to see the top picks—well worth a look for your stargazing adventure!
