The Hubble Space Telescope took this picture of Comet ISON on April 10, 2013, when the comet was slightly closer than Jupiter's orbit, or about 386 million miles from our sun.

In November, Comet ISON is expected to dive into the sun's atmosphere. Rolando Ligustri used a telescope at the <a href="http://www.castfvg.it/" target="_blank">CAST Observatory</a> in Italy to capture this image of it on February 28.

Comet PanSTARRS put on a show in both the Northern Hemisphere and Southern Hemispheres earlier this year. This image was taken by amateur astronomer Terry Lovejoy on February 12, 2013, from Brisbane, Australia. He used a QHY9 camera and an 8" telescope with 5 minutes exposure.

In 1986, the European spacecraft Giotto became one of the first spacecraft to encounter and photograph the nucleus of a comet. This photo shows Comet Halley's nucleus. The debris from the nucleus creates the trail of debris responsible for the Orionids meteor shower each October and the Eta Aquariids in May.

On July 3, 2005, NASA's Deep Impact fly-by spacecraft dropped its "impactor" probe into the path of Comet Tempel 1. There was a bright flash as the probe hit the comet. The images were beamed around the world in near real time on NASA TV and over the Internet. Orbiting telescopes watched from space and astronomers on the ground captured images, too.

Comet Wild 2's nucleus was photographed by NASA's Stardust spacecraft as it flew past in January 2004 and collected samples from the comet's coma. The spacecraft's return capsule ferried the samples back to Earth on January 15, 2006.

After returning the world's first particles from a comet, the Stardust capsule was packed up and shipped to the Smithsonian. The mission's principal investigator was surprised by the size and composition of the particles captured in the capsule's aerogel-lined collector.

Comet Linear was photographed by a camera on the European Space Agency's Rosetta space probe on April 30, 2004. Rosetta is on its way to study Comet 67-P/Churyumov-Gerasimenko. On June 8, 2011, Rosetta was placed in hibernation. It will wake up when it reaches the comet in mid-2014, when it will drop a small lander onto the comet's surface.

One of the most famous comets is Hale-Bopp. It was discovered independently on July 23,1995, by Alan Hale in New Mexico and by Thomas Bopp in Arizona. It was one of the brightest comets in decades and was visible to the naked eye for several months.
