On March 2, 2025, I released the very first version of CosmoTalker โ an offline Python library built for exploring space data like planets, galaxies, and cosmic insights.
Fast-forward to today โ over 20,000 downloads later โ I'm overwhelmed with gratitude and joy! ๐โจ
๐ What is CosmoTalker?
CosmoTalker is:
- ๐ฐ๏ธ A Python module for offline space data (perfect for hobbyists & learners)
- ๐งช Includes real-time scientific facts, search tools, and preview images
- ๐ฅ๏ธ Designed for students, developers, and space lovers alike
- ๐ Now accessible also for
.deb
(Linux-ready!)
GitHub: github.com/bhuvanesh-m-dev/cosmotalker
๐ What Happened in 5 Months?
- โ Crossed 20K+ downloads (tracked via pepy.tech)
- ๐ป Published CosmoTalker v2 with:
- Beta image preview tool
- Advanced search
- Real-time astronomical data
- ๐ฆ Packaged for multiple platforms .deb
- ๐ Launched the official webpage: bhuvaneshm.in/cosmotalker
๐ฏ Why I Built It?
As a CSE student fascinated by astronomy, I wanted to create a tool that could:
- Help students explore space concepts easily
- Work offline, so no internet = no problem
- Be lightweight and open-source
๐ก Lessons I Learned
- Documentation is everything: Good README = better user trust.
- Start small, then scale: I started with just a few planets and expanded features gradually.
- People love useful tools: Even small utilities can have a big impact.
๐ฌ What's Next?
- ๐ญ Add telescope integration via plugins
- ๐ Space mission timeline visualizer
- ๐ง AI-powered space Q&A mode (powered by Local LLMs)
- ๐ Community feedback board
๐ Thank You!
To everyone who downloaded, tested, starred โญ, and supported the journey โ I truly appreciate you. CosmoTalker will keep evolving with more starry features! ๐
