Meteors From Comet Hartley 2 Amaze Skywatchers
This is how Comet Hartley 2 might appear in the eyepiece of a large amateur telescope. Located about eight degrees (16 full moon diameters) away from the bright star Procyon as it leaves the constellation Gemini, Comet Hartley will be best viewed high in the sky just before dawn.

Comet Hartley 2 and Earth's Ocean Water
Credit: NASA/JPL-Caltech/R. Hurt
Measurements from the Herschel Space Observatory show that comet Hartley 2, which comes from the distant Kuiper Belt, contains water with the same chemical signature as water in Earth's oceans. The findings may help explain how Earth’s surface ended up covered in water.

Twin Fireballs May Have Come From Comet Hartley 2
These two fireballs with orbits similar to the comet Hartley 2 were observed on Oct. 16. 2010 by cameras in western Ontario (left) and the southeastern USA (right). The fireballs may have been caused by meteors from the comet.

Comet Hartley 2 Gets Visit from Deep Impact Spacecraft
Credit: NASA/JPL-Caltech/UMD
NASA's Deep Impact probe took this image of comet Hartley 2 on Nov. 2, 2010, from a distance of 2.3 million kilometers (1.4 million miles). The white blob and the halo around it are the comet's outer cloud of gas and dust, called a coma. At this distance, the spacecraft captures images with a resolution of about 23 kilometers/pixel (14 miles/pixel).
