Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
stellarium
- Stellarium is a free GPL software which renders realistic skies in real time
- Constellations are younger than continents

Not sure what this would be. Ive seen it for years and thought it was just a weirdly rectangular cluster of stars. What do you guys think?
They're the Plieades. For future reference you can check on what's in the sky with software like Stellarium.

NROL-22 TLE DATA SMOKING GUN. (USA 184—-~~>”USA 184 r”). YAHTZEE ! ✈️🌏🛰🎯👀😱
Btw, seems it is gone because the account was deleted https://github.com/Stellarium/stellarium/discussions/3277 back in June of 2019

‘Limited' UFO disclosure believed to be used soon as a strategy of deception as end times Bible prophecy being fulfilled indicates. The truth about the future and how to be prepared.
We have been experiencing distress and perplexity of nations upon the earth unlike anything in modern history. There have been record hurricanes, cyclones, typhoons, and flooding globally which appears to relate to “the sea and the waves roaring” and according to research using the Stellarium Astronomy Software, this was a one time alignment on September 23, 2017 involving the sun, moon, and stars that accurately matches the reading of Revelation 12:1-2 word-for-word, the last book of the Bible foretelling the end of the age.

When it comes to software what do you use and can you go a little bit into detail on how to use it
Stellarium - Planning out targets and just seeing what's up in the sky on any given night
- Any free space simulators like universe sandbox 2 ?

Floating Feature: A Sky Built Before Us - The History Of The Stars
I did a bit of poking around using Stellarium and found two stars that I thought were admirable candidates, and I wasn't sure why Nell and Ruggles didn't think so: Phecta and Megrez, Gamma and Delta Ursae Majoris. These are the two stars that make the left side of the 'scoop' of the big dipper. According to Stellarium they were at their closest to being in a north-south alignment in the year -2586, that is 2587 BCE, with right ascensions differing by just 1.28 s (0.00036°). They were 15° and 20° from the pole at the time.

I'd like to share my personal web project. Those who are into astronomy might wanna see this.
But if you need an API i think stellarium.org has an one.

Portable, cross-platform, reliable 3D library?
If I wanted to build an app like Stellarium, displaying a 3D model, but not requiring fast animation, not a game, more visualization, what libraries should I be considering for the display/UI portion of this program?
gpredict
- ELI5: If there are many satellites orbiting earth, how do space launches not bump into any of them?

Orbit and footprint viz
I didn't watch the video but Gpredict has tracking and a map showing the orbit path and ground footprint for satellites you select.

My homemade QFH antenna, with some images I’ve captured from NOAA and Meteor satellites.
I'm using sdrpp with Doppler correction with gPredict. I record the signal in sdrpp and then process it with noaa-apt.

Interfacing a go-to mount with the Orbitron software.
Your missing the point basically they mean upgrade your software to Gpredict satellite tracking software (GPL) which has Linux and Windoze versions. http://gpredict.oz9aec.net/ Gpredict uses hamlib to control both radios and mounts. Hamlib supports many radios and mount support includes Meade, Celestron and iOptron IEQ45 alt-az mounts via AUSCOM standard software. Once done the next part is ensuring you set up you com ports to appropriately control your devices radio and mount and making sure the appropriate devices are set-up in the software. Note if your com ports change say because you replug something, don't forget to update the port details otherwise coms will fail and the relevant device won't be usable. Check out the documentation and there are a number number of set-up videos on YouTube if needed.

FOSS for Amateur Radio
LWN usually has great content but they've missed out on so much free ham software in this article that I use regularly.
My main HF rig is an older Yaesu FT-950. I tapped the IF and brought it out of the chassis where it is plugged into a cheap RTLSDR. I then access that RTLSDR (with free drivers) with GQRX (free software for visualizing anything compatible with SoapySDR or GNU radio), and the result is that I get a panadapter that is arguably better than what's available on $2000 radios. Short video here: https://photos.app.goo.gl/uP9zMMbiiiSmHYvM8
As for VHF/UHF stuff, I would be hopeless if it wasn't for GPredict on my laptop making it simple to track LEO satellites. https://github.com/csete/gpredict Short video here: https://photos.app.goo.gl/eg87BWpt2XnJdGFp7
I also run an APRS igate, which is powered by direwolf: https://sielicki.github.io/posts/radio-scanner-aprs-igate/ , https://github.com/wb2osz/direwolf

Making Sense of Satellite Data, Open Source Workflow
It hasn't been updated in a couple years now, but `gpredict` is a nice desktop program that will show projections of satellite orbits and predict upcoming passes.
