Elizabeth Landau, NASA Jet Propulsion Laboratory Comet C/2013 UQ4 (Catalina) has been observed by NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft just one day after passing through its closest approach to the sun. The comet glows brightly in infrared wavelengths, with a dust tail streaking more than 62,000 miles (100,000 kilometers) across the sky. Its spectacular activity is driven by the vaporization of ice that has been preserved from the time of planet...

Whitney Clavin, NASA's Jet Propulsion Laboratory NASA's NEOWISE mission captured a series of pictures of comet C/2012 K1 -- also known as comet Pan-STARRS -- as it swept across our skies in May 2014. The comet is named after the astronomical survey project called the Panoramic Survey Telescope and Rapid Response System in Hawaii, which discovered the icy visitor in May 2012. Comet Pan-STARRS hails from the outer fringes of our solar system, from a vast and distant reservoir of...

ESA Expects The Unexpected As Rosetta Nears Comet Rendezvous
2014-06-20 09:49:28

April Flowers for redOrbit.com - Your Universe Online The European Space Agency's (ESA) Rosetta spacecraft is the first mission in history to attempt to rendezvous with a comet. The spacecraft will deploy the Philae lander to the surface of the comet and accompany it as it orbits the Sun. The comet in question is 67P/Churyumov-Gerasimenko, which is currently approximately 267,189 miles from the spacecraft. The Rosetta team released a series of images last May that detailed the extended...

Rosetta at Comet

NASA Three NASA science instruments aboard the European Space Agency's (ESA) Rosetta spacecraft, which is set to become the first to orbit a comet and land a probe on its nucleus, are beginning observations and sending science data back to Earth. Launched in March 2004, Rosetta was reactivated in January 2014 after a record 957 days in hibernation. Composed of an orbiter and lander, Rosetta's objective is to arrive at comet 67P/Churyumov-Gerasimenko in August to study the celestial...

ISEE-3 Comes Back To Visit Earth

NASA It launched in 1978. It was the first satellite to study the constant flow of solar wind streaming toward Earth from a stable orbit point between our planet and the sun known as the Lagrangian 1, or L1. Monitoring that wind helped scientists better understand the interconnected sun-Earth system, which at its most turbulent can affect satellites around Earth. In 1984, it was given a new mission and called the International Cometary Explorer. In September 1985, it passed directly...
