What it does
Cosmic Facts brings NASA's deep space data into one premium app. Browse daily Earth photos from 1M km away (DSCOVR satellite), track ISS in real-time, calculate orbital mechanics with real physics, and explore 6,000+ confirmed exoplanets. 50+ features including 3D Solar System, APOD archive, asteroid tracker, space weather, 84 lessons across 12 topics, and quizzes. Free forever, no ads, no signup. Built solo by an Indian developer who couldn't find a non-bloated space app he liked.

Atlas of Space2025 · atlasof.space · ▲770Hello HN! Sharing a recent side project of mine, the Atlas of Space, that I built out to explore the Solar System. As a long-time space nerd, I realized recently that I didn't have a good intuition on the scale, speed, and relative orientation of the celestial bodies around us. So over the break I built out a kind of spatial Wikipedia to click around and learn about planets, moons, asteroids, and other bodies orbiting the Sun. The physics is all simulated in the browser using simple Newtonian mechanics. There's a lot left to do from here, including modeling objects in non-Keplerian orbits…

Beautiful 3D ISS tracker with live video and near-realtime clouds2024 · iss.matteason.co.uk · ▲139This is a little hobby project that I hope you enjoy. You can see where the International Space Station is now, with live HD video from NASA, on a realistic 3D globe. The positions of the sun and moon are also accurate, though distances aren't to scale. The clouds are also near-realtime; I span that out into a separate project at https://clouds.matteason.co.uk, where the cloud images I create from EUMETSAT data are freely available. I've got more features almost ready to go, like the ability to turn off all UI, toggleable clouds and turning off the day/night cycle I'd love for…
- DADailySpace, Android app for exploring space photos and rocket launchesJan 2026 · play.google.com · ▲7
Hi HN, I’ve always been fascinated by space and how much is happening beyond what we usually see day to day. I wanted a simple way to explore space photography and learn what I was actually looking at, without jumping between lots of different sites or long articles. So I built DailySpace, an Android app for exploring a large collection of space photos with short and clear explanations. You can browse thousands of images of galaxies, nebulae, planets, stars, black holes, Earth, and different NASA missions organized into categories or found through search. As I kept using it myself, I added…

Parallel agents, diff reviewer, and multi-model comparisons

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
