CG 30: Cometary Globules
NASA · Picture of the Day

CG 30: Cometary Globules

They're like mountain peaks, but they are forming stars. Bright-rimmed, flowing shapes gather near the center of this rich starfield toward the borders of the nautical southern constellations Puppis and Vela. Composed of interstellar gas and dust, the grouping of light-year sized cometary globules is about 1300 light-years distant. Energetic ultraviolet light from nearby hot stars has molded the globules and ionized their bright rims. The globules also stream away from the Vela supernova remnant which may have influenced their swept-back shapes. Within them, cores of cold gas and dust are likely collapsing to form low mass stars whose formation will ultimately cause the globules to disperse. In fact, cometary globule CG 30 (upper right in the group) sports a small reddish glow inside its head, a telltale sign of energetic jets from a star in the early stages of formation.

Six ways to explore space

Every feature is live, free, and requires no account.

Getting started

How it works

From picking a city to tracking asteroids — three steps, zero sign-up.

01

Pick a city

Search any of 33,000 cities worldwide or use your current location. Each city gets a personalised sky report.

02

See the live sky

Explore an interactive panoramic view with real-time planet positions, the Moon, ISS passes, and meteor showers — adjusted for local weather.

03

Track asteroids & aurora

Monitor near-Earth objects with risk classification, and check cloud-adjusted aurora forecasts for the world's best viewing cities.

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.
