Longmore 8: The Hamster Wheel Nebula
How did a hamster wheel get into space? The Hamster Wheel Nebula (Longmore 8) was discovered by Andrew Longmore in 1976 as a part of a larger survey of the southern sky. This survey employed several improvements in photographic technology, including the use of highly sensitive film, to capture deeper and fainter objects on plates that were examined by eye and catalogued. The featured image, taken at Observatorio El Sauce in Chile, depicts an intricate wheel structure of glowing hydrogen that was thrown out into space by a dying star and ionized by the leftover white dwarf. This structure was barely visible on the original plate, emphasizing the power of modern telescopes and cameras. Two opposing clumps of red hydrogen gas encased in the blue veil of ionized oxygen hint at the presence of a companion to the bright white dwarf at the wheel’s center!

Answers to common questions
Everything you need to know about the data, the forecasts, and what SkyTracko tracks for you every night.
SkyTracko shows you which planets, the Moon, the ISS, and meteor showers are visible from your city right now — cloud cover and moon phase included. Pick a city from the hero above or open the sky map to see a per-city report.
We combine NOAA's Kp index forecast with real-time cloud cover from Open-Meteo to produce a per-hour, cloud-adjusted visibility probability for each city. The forecast refreshes every 15 minutes and covers the next 72 hours.
The asteroid tracker lists every near-Earth object approaching in the next 60 days, sourced from NASA NeoWs. You can sort by closest, soonest, largest, or highest risk — and see the distance in lunar distances plus plain-language meaning ("Inside lunar orbit", "Well beyond lunar distance", etc.).
Asteroid data refreshes every minute in the browser and is synced from NASA NeoWs every six hours. Aurora and sky conditions refresh every 15 minutes. Each page shows the most recent sync time so you always know how fresh the reading is.
Yes — every feature on SkyTracko is free and requires no account. Optional sign-in is planned to let you save your favourite city and get notified about notable asteroid approaches and aurora events.
