I have been searching online for information, but i fail to find anything concrete....

On Dec. 30, 1930, the first-ever photo of the Earth’s curvature was taken by Lieutenant Colonel Albert William Stevens, who was an officer in the U.S. Army Air Corps and an aerial photographer....

Cycle 25 solar maximum made 2025 a great year for aurora borealis (or aurora australis) on planet Earth. And the high level of solar activity should extend into 2026. So, while you’re celebrating the arrival of the new year, check out this spectacular auroral display that erupted in starry night skies over Kirkjufell, Iceland....

So, if an academic paper is published in an open journal by an average citizen with an obsession for learning from online sources. So, there are no credentials but a decent work history. A prestigious college downloads the paper. What are the possible reasons?

Hey everyone!...

As we're approaching the summer solstice, I'm going to harden my heart to the fact that it won't be getting nice and dark until, like, ten where I'm at. What are you guys going to be looking for tonight? If you're not going out, do you have any recommendations?...

So I’ve been posting space related stuff here for a while over !space to distribute content more, within the last few weeks though it was closed and now directs posting to this other mander space comm !space which is titled “Space & Astronomy”...

Hey everybody, I know it’s a little late, but I wasn’t really sure how the weather was going to be until a little while ago. I’d like to invite you all to join me in looking at the sky tonight. What’s on the menu:...

I’m planning to go to a rural spot that has a Bortle class 3 night sky around Southern California. Can anyone recommend a beginner friendly telescope with decent magnification for around $200? I’m not interested in using an accompanying smart phone app to go with it either. I’d like to see nebulae and galaxies the most....

Looking like the clouds are finally going to break tonight. The moon’s quickly heading towards the new moon, and we’ve got Virgo rising. I’m excited to get out and check some targets off my list....

I know we did Fridays last time. The weather was bad, so I kinda forgot about it. The transparency tonight is looking suboptimal, and, given my options, I might just settle for hitting some binary stars. My best view is of the eastern sky, and most everything there right now is faint fuzzies, so I don’t have especially high...

I’ve got clear skies where I’m at, and I’m ready to try and cross some things off my observation list....

Does anyone have any experience home brewing a radio telescope? I’d really like to make one myself, both because it seems fun and challenging, and because it would probably be cheaper than buying one of there are any consumer grade radio scopes. I’m aware of some tutorials online, and one concern that I have is that many of...

Hey everyone! I’m putting on stargazing classes in my city with the help of the city parks dept. It involves lugging out 12" dob (we mostly hang out ~120x mag, but I have plans to really juice the magnification if we get small classes and good seeing), some binoculars, and a green laser pointer. I just did the first one last...

The DESI Collaboration (en.wikipedia.org/…/Dark_Energy_Spectroscopic_Inst…) has released results from its first year of observations....

Observations with the LOFAR (Low Frequency Array) radio telescope last year showed that first generation Starlink satellites emit unintended radio waves that can hinder astronomical observations. New observations with the LOFAR radio telescope, the biggest radio telescope on Earth observing at low frequencies, have shown that...
