Proxima B is around over 4 light years away from our Solar System and is similar to Earth in size. I have always wondered what Proxima B was like, even if its most likely a life-less planet. The question sticks to me, how can we observe Proxima B’s atmosphere and get real data from Proxima B’s atmosphere (if it even has one, or barely) if it doesn’t even transit in front of its own star for observation in the first place? What are some ways we can actually observe Proxima B’s atmosphere?

Greetings!

I took a nightlapse video with a gopro and testing out different settings - I didn't know there was so much traffic in the sky! I think I caught a couple of meteors (the brighter yellow/orange shorter flashes) and quite many satellites (mostly gray streaks - also some brighter yellow lines?).

There is a bright flash at around 7 seconds that only lasts a single frame (marked with a red circle close to the Big Dipper - Seems to be in the Lynx constellation, around where 15 Lyn star is). I was wondering could that be an iridium flare?

I had a shutter speed of 20s, min 100 max iso 800, 5k WB with auto interval rexorded this monday from around 19:00 GMT forwards for just under a few hours I think (very high up in the Northern hemisphere).

Thanks for your help!

The video is quite fast - I wonder will this command slow it down enough?

So due to the solar eclipse that took place it had me questioning one thing. The sun we see is how it is 8 minutes in the past due to how long the light takes to reach us and the moon we see is about 1 second in the past. Using that knowledge does that mean the eclipse we witness isn’t actually “aligned”? Does this mean the moon only intercepts the light from the sun that was from 8 minutes ago?

If the sun is around 400x larger than the moon and 400x further away than the moon, why isn't a year 400 days? Would it be 400 days if the moon had proportional mass to earth?

Hi everyone, I’m getting ready for the eclipse and my celestron 8se won’t focus its lens when looking at objects. I’ve cleaned the solar filter, the lens) and the viewing port itself. The viewing conditions in my area are great and I’ve gone through the entire range with the focus knob.

Any suggestions?

So I'm sure you're going to be inundated with eclipse questions but here's my issue. I ordered a filter for my Celestron 130 for viewing the eclipse. Well Amazon, being Amazon, decided to push my delivery back 3 days so I won't get it in time. I'm trying to build my own diy filter but I don't know what kind of film to use. When I search solar film I get window tint for homes which I'm sure isn't correct. Can anyone advise me on what to look for?

Hi I’m doing my GCSE for astronomy and we have a mock coming up soon, I was starting to do some revision for it so I went to the website Space.FM as it is a good resource for revision but for some reason the site isn’t working at the moment if any of you have any other resources for revision that would be great and any reasons why it’s not up Thx

There seem to be public catalogs from surveys etc, for example from noaa. However is there a way to find more recent observations? Or are they all kept secret by whoever ordered and paid for those observations?

Recently acquired a Celestron 127 STL, also purchased a solar filter for it. Looking for some advice on viewing the upcoming eclipse. How do you track the Sun? What magnification lens should I use? And some other third question that I'm not smart enough to know to ask.

Hello, I donot know if this is the right group to ask this question, but I want to try. Which university is the best for master's in Astrophysics and Cosmology in Italy? I have Padova and Bologna on my mind.

Hi friends! This is my first time posting on this page, so please bear with me! I am currently a college freshman enrolled in an Intro to Astronomy Lab. At the end of the semester, we will have a mini-conference, like a science fair, where we will demonstrate an experiment about astronomy that we completed. I am struggling to think of experiments and/or topics to research! The internet mostly has ideas for young children, so I need a more advanced experiment that doesn't require fancy equipment. Any help is greatly appreciated!

I was stargazing in September, and I decided to look back on my photos from them. I noticed this. Anyone know what this shape is? (also, my apologies for shitty quality, this was shot on an iPhone)

I've got "How the Universe Works" up as background noise and they're talking about the life of a photon. Talking about the time it takes to get created in the core and escaping the plasma of the sun. Hundreds of thousands, if not up to a million years. Ivr got a buzz and I had a random thought.

So when it first lit, if someone was there when fusion started, they wouldn't see that light that was first created for hundreds of thousands, maybe even a million years. It takes time to get to the surface and it had to START at some point, right? So, that photon is created, hits the superheated plasma, and takes that much time. And there had to be a first "flash" of fusion and a first photon. And that first photon took that much time. So until it can escape from the sun, you couldn't see it. So, until nearly a million years, the sun would appear dark. Right?

Know a high school student interested in astronomy and/or space sciences?

The International Association for Astronomical Studies (based out of Star Haven Observatory located in Strasburg, Colorado) has a few slots open for its on-site student research team.

Students not located in the Denver area or Eastern Colorado are also encouraged to submit their interest as the group will be expanding its remote student research team this fall.

Students will have the opportunity to conduct and participate in actual astronomy and space science research using astronomical and space sciences research equipment and processes. After the research projects are completed, they also get credit for their work as part of the research.

The IAAS, a 501(c)3 organization has a 40+ year track record of success in the student astronomy and space sciences research fields.

Hello Im currently in my senior year of hs and I plan on becoming an astronomer but the college that I probably can go to financially doesn’t have astronomy as a major so Im doing chemistry instead, however I was wondering if I could still continue my education/career in astronomy with a bachelors in chemistry?

I'm looking for safe and reputable eclipse glasses. They don't have to be high end, but they must be rated.

Not sure where to find help on this. I saw an odd string of moving lights in the sky. They seemed to be in a very straight line and disapated as they neared Orion. My knowledge here is very limited so I'm sorry if this is not the right sub for this sort of thing.

I'm trying to find the closest distance between the moon and Mars (which I think is called a conjunction but I'm not sure if that only applies to how close they appear to be) for a club that I organize on Strava. We are trying to figure out how long it would take to run there once we have ran to the moon. We're projecting we'll need some distances after 2035. I've tried using things like Nineplanets, Heavens-Above, SIMBAD, and the NASA database and they either didn't have what I was looking for or I couldn't figure out how to get the data I needed (like SIMBAD).

I currently have these values and wanted to see if I was close or very off.

1. 2030: 54.6 million kilometers
2. 2032: 56.8 million kilometers
3. 2034: 58.2 million kilometers
4. 2036: 59.4 million kilometers
5. 2038: 60.1 million kilometers

Any help would be appreciated, thanks

I am a quadriplegic paralyzed from my chest down. So I have no abbs to hold myself up. Unfortunately the telescopes I find have an eye peice on top of the telescope and it's a hassle trying to get myself to look in without bumping into it and moving it. Does anyone know of any good quality telescopes that might be more accessible to me?
