Vaporizing Meteor Photobombs the Lacerta Nebula
Today's window into deep space: Vaporizing Meteor Photobombs the Lacerta Nebula. The story behind the image:
Why this matters
Today's highlight centers on deep-space objects, the Moon, solar activity. Understanding how these objects form and move is the bridge between a pretty photo and the live, data-driven sky we render on the globe.

The science, from NASA's Astronomy Picture of the Day
What's happening to this meteor? This bright meteor streak appeared and disappeared quickly during a long exposure of the Great Lacerta Nebula, seen faintly in red toward the center of the image. The meteoroid, likely a small pebble, creates its glow partly by heating and exciting surrounding air in Earth's atmosphere, but itself vaporizes and leaves wind-blown gas and dust with colors that give clues to its composition. The featured image was captured last month from Death Valley Observatories in Nevada, USA. This month, though, is particularly good for seeing meteors. Presently there are three meteor showers ongoing, although they are currently competing for visibility with the glow of a bright gibbous Moon. The most active of these showers, the Perseids, will be busiest in about 10 days -- after the Moon has dimmed considerably. This year, the Perseids peak nearly coincides with not only a new Moon, but, from some locations, one that totally eclipses the Sun. Sky Surprise: What picture did APOD feature on your birthday?
