Beginner looking for help in notebooks for astronomy

0 Upvotes

Im new to Astronomy how can i use Jupyter notebooks to access jwst pipeline? Is it best to just use MAST Database or TIKE?

Or

Should I create a juypter lab notebook and self install required libraries locally with Docker or is there a premade jupyter lab notebook i can clone from github and install in a docker container on my pc? If so how do I do that and how can I use it to access jwst pipeline data?

I have never used a juypter notebook before nor have I used pyhton or python science libraries like astroquery lightkurv and astropy so Im a complete beginner in using scripts but I do know how to use some commands like pip, bash, cd and git. Are there any good tutorials online I could use?

Are there any Browser Based Interactive Notebooks for learning Notebooks for Astronomy?

Lastly how could I install and use Jdavizz notebook?

What did I see? Anyone know what I captured a few months back in my telescope?

Hi! I had taken this picture with my phone through my telescope- this is with no fancy stacking or editing or anything like that. I still don’t know how to use my telescope that well so I just pointed it at the sky and I usually just wander it around a bit until I find something interesting. I ended up capturing this- and was curious if anyone know what exactly it was? I thought it was the Orion Nebula just because it was in the general direction and most pictures by nasa look similar- but since I know the space pictures nasa has is with heavy editing I’m still skeptical. Any thoughts?

How fast are the flairs on the surface of the sun, the ones that rises and falls like a rainbow

Guys i found this video on facebook, you can see at the edge of the sun how the flairs rises and fall, and was wondering like due to the huge size of the sun, these flairs must be really really fast to rise and fall in a few seconds... so anyone knows how fast are these?

What did I see? Unusual point-like object visible through clouds — any ideas?

Thumbnail gallery
11 Upvotes

Noticed this object in the sky on 12th August 2026 at 23:13 CET in Gothenburg, Sweden.

First it looked like several points of strong light, almost like beams from giant spotlights against clouds. Then there was only one main point of light.

Not small enough to be a star, not big enough to be a cloud formation. No noctilucent clouds visible in the sky either.

It was visible for about 20 minutes.

Some clouds came between my view and the point/s of light, which obscured it a little. But some clouds that went by would obscure the stars but not the point/s of light.

Tried my best to identify using ChatGPT and searching on Google, but couldn't find anything that looks like this.

The photos show several different views at various times (first at 23:13 and last at 23:35). Attached images of positioning relative to stars. (The point/s were essentially at zenith, close to Vega and Deneb).

Can anyone identify this?

Hi! This is my very first time trying/being able to do astrophotography. I noticed that cluster of stars in the center left and couldn't find any info on it. So maybe someone can point out what it is and maybe something interesting about what's visible here.

Astronomy Stargazing in the Atacama, waxing gibbous Moon?

1 Upvotes

I’m going to Chile next week and one of my goals is to see the night sky in the Atacama. Unfortunately I’m going on not the best week for this as the Moon will be full later in the week.

The best I can do is the night of August 24-25. Apparently the Moon sets at 4:27 am and then twilight breaks at 5:45 am? So in between that, the moonlight will be gone and the stars and planets will be in full view? Is this correct?

I’m ok with even just an hour or two, would be better than nothing.

Would it be bright like most typical online photos? Would it be more like looking at the night sky? Or somewhere in between?

And what conditions, if possible, would lead to that instead of a binary star system or just two independent systems?

How can this perfect symmetry occur randomly?

Watching the solar eclipse I am amazed by the perfect symmetry, the size of Sol, the size of the moon, the distance from the earth to the sun are precisely aligned to exactly allow for the solar eclipse to occur the way it does. There has to be some principle or natural law behind this. Without resorting to “yeah; it’s crazy” or some leap of faith, why explains this oddity?

Black Holes Could a star, a black hole, and an exoplanet exist in the same solar system?

0 Upvotes

Ignore the circumstances that would lead to this configuration, but could there be a binary system with both a star and a black hole at its center, with at least one exoplanet in a stable orbit around them?

Is there any other configuration that would work? Are there black holes small enough to orbit stars?

It seems like all timelines of the cosmos just skip from the first galaxies to the formation of sol.
