APOD

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

A view of mountains over clouds shows a starfield with a purple glow. Prominent on the right is the trail of a bright meteor. To the left of the meteor and connecting to the meteor is something unusual: a light brown triangular puff. Please see the explanation for more detailed information.

Meteor Dust

Explanation: What's happening to this meteor? It is shedding its outer layers as it passes through the Earth's atmosphere and heats up. The sudden high temperatures not only cause the bright glow along the dramatic streak but also melt and vaporize the meteor's component rock and ice , creating dust. Wind in the atmosphere typically blows this dust away over the next few seconds, leaving no visible trace after only a few minutes. Much of this dust will eventually settle down to the Earth . The featured image was captured in mid-December, coincident with the Geminids meteor shower . On the upper left is Sirius , the brightest star in the night sky , while in the foreground is fog-engulfed Huangshan , the Yellow Mountains of eastern China .
