A newly discovered comet is making a kamikaze dive into the sun today, just hours after a solar storm sent a massive cloud of charged particles streaking into space. As Spaceweather.
Student of Petrozavodsk State University and an amateur astronomer Artem Novichonok discovered a new comet. Novichonok found the object studying pictures made by the automated astronomy station TAU in Kabardino-Balkaria.
Dwarf Comet 45P/Honda Mrkos Pajdusakova on August 15, 2011, at 08.16 GMT (12.16 GMT) will approach the Earth at a distance of 0.06 astronomical units (8.9 million kilometers). At this point, the comet will be in the circumpolar constellation Mensa, and it can not be observed in the northern hemisphere
American astronomers have discovered in the spectrum of comet C/2010 X1 Elenin traces of hydrocyanic acid. Michal Drahus from the University of California at Los Angeles and his colleagues observed Comet Elenin using James Clark Maxwell (JCMT) 15-meter submillimeter telescope on July 30, located on Mauna Kea in the Hawaiian Islands.
Russian astronomers have discovered a second comet in six months, received the designation P/2011 NO1.
The first russian comet over 20 years, called C/2010 X1 (Elenin), discovered in December 2010, astronomer Leonid Yelenin of the Institute of Applied Mathematics of the Keldysh
New findings from NEOWISE, the asteroid and comet-hunting portion of NASA’s Wide-field Infrared Survey Explorer mission, show that comet Hartley 2 leaves a pebbly trail as it laps the sun, dotted with grains as big as golf balls.Previously, NASA’s EPOXI mission, which flew by the comet on Nov. 4, 2010, found golf ball to basketball-sized fluffy ice particles streaming off comet Hartley 2.
The European Space Agency’s Rosetta spacecraft pursued the comet 67-P/Churyumov-Gerasimenko for more than seven years. And now finally Rosetta can take a series of 52 pictures from a distance of about 101 million miles (163 million kilometers) from comet 67-P/Churyumov-Gerasimenko.67-P/Churyumov-Gerasimenko is about 2.4 miles (4 km) across and completes one orbit around the sun every 6.6 years.
The second time, in the last ten days, one of NASA’s twin STEREO spacecraft fixes the case of the comet, flying toward the sun. As and the last time, that happened in mid-May, an attempt to impact the comet with the sun accompanied by powerfull coronary emissions
The researchers observed Hartley-2 six times during the summer, fall and winter of 2010.All data which will be collected by Mumma’s team and detailed images of the comet taken by NASA’s EPOXI mission show that the comet’s core is not uniform.
