About Astroneo

Our Mission

The universe is unimaginably vast — spanning 93 billion light-years in observable diameter, containing more than two trillion galaxies, and hosting an estimated 10²⁴ stars. For most of human history, exploring this cosmic expanse required access to expensive telescopes, university observatories, and dense academic papers written for specialists.

Astroneo was built to change that. We created a platform where anyone with an internet connection can search our catalog of over 8,800 stars, explore detailed profiles of black holes including Sagittarius A* and M87*, interact with 3D simulations of cosmic objects, use an augmented reality sky map tied to their real-time GPS location, and read science-accurate educational articles written in plain language.

Everything on Astroneo is and will always be free. We believe that access to knowledge about our universe is a fundamental right — not a privilege reserved for those who can afford a subscription.

What We Offer

Astroneo brings together multiple tools under one roof to give users the most comprehensive free astronomy experience on the web:

• Star Search & Explorer: Search and browse our catalog of 8,800+ real stars, each with spectral classification, distance, luminosity, temperature, and constellation data sourced from the HYG stellar database.
• Black Hole Profiles: Detailed, accurate profiles of famous black holes — including Sagittarius A* (the supermassive black hole at the center of the Milky Way), M87* (the first black hole ever imaged), Cygnus X-1, V404 Cygni, and TON 618 — with visualizations and scientific data.
• Interactive Sky Map: A real-time augmented reality sky map that uses your device's GPS and orientation to show you exactly what stars and constellations are above you at any moment.
• 3D Simulations: Explore 3D interactive models of black holes, complete with accretion disks and relativistic jet visualizations.
• AstroBot AI Assistant: An AI-powered chatbot trained to answer questions about astronomy, space science, and our universe — available on every page.
• Astronomy Blog: Regularly updated articles covering deep-space discoveries, stargazing guides, telescope tutorials, and educational deep-dives into cosmological concepts.
• Upcoming Events: A calendar of upcoming astronomical events — meteor showers, eclipses, planetary conjunctions, and more.

Our Technology

Astroneo is built with modern web technologies designed to deliver a fast, accessible, and beautiful experience across all devices. Our frontend is built with Next.js and TypeScript, ensuring fast server-side rendering and excellent SEO. Our 3D visualizations use WebGL and Three.js to render realistic astronomical simulations directly in the browser without requiring any plugins or downloads.

Our star catalog data is sourced from the HYG Database (a compilation of the Hipparcos, Yale Bright Star, and Gliese catalogs) and enhanced with data from NASA's HORIZONS system, ESA's Gaia mission, and the SIMBAD Astronomical Database maintained by the Strasbourg Astronomical Data Center.

Our AI assistant (AstroBot) is powered by Google's Gemini AI model, fine-tuned to provide accurate, scientifically grounded answers to astronomy questions. All astronomical data displayed on the platform is cross-referenced against multiple authoritative sources before being published.

Our Story

Astroneo began in 2024 as a personal project by a developer passionate about both astronomy and accessible web technology. The original concept was simple: create a star search tool that was faster, more beautiful, and more informative than anything that existed at the time.

As the project grew, so did its scope. User feedback poured in requesting black hole profiles, an interactive sky map, a blog, AI chat, and more. Today, Astroneo serves thousands of users monthly — from school students doing astronomy projects to amateur astronomers planning their next observing session to professional researchers looking for a quick reference tool.

The platform is maintained and continuously improved by a small, dedicated team committed to scientific accuracy, elegant design, and the democratization of astronomical knowledge.
