Searching For What Is Left OF Comet ISON
2013-12-05 08:56:07

NASA Just prior to its closest approach to the sun on November 28, Comet ISON went through a major heating event, and likely suffered a major disruption. At this time, scientists are not sure how much of the comet survived intact. We may be seeing emission from rubble and debris in the comet's trail, along its orbit, or we may be seeing the resumption of cometary activity from a sizable nucleus-sized chunk of ISON. Most agree that up to 90 percent of ISON was destroyed, leaving...

New Comet Discovery May Be Brightest Visitor In Past Hundred Years

Lawrence LeBlond for redOrbit.com - Your Universe Online Hale-Bopp, Haley´s, McNaught. These are just a few of the more well-known modern comets that have blazed across the night sky in our lifetime. Another comet that has been recently discovered could be added to that list next year when it makes a pass by the Sun in late 2013. The comet, named C/2012 S1 (ISON), is due to come within 1.1 million miles of the Sun on, or around, November 29, 2013. Vitali Nevski and Artyom...

Comet Corpses In The Solar Wind
2012-01-21 04:13:51

[ Watch the Video ] A paper published in the Jan. 20th issue of Science raises an intriguing new possibility for astronomers: unearthing comet corpses in the solar wind.  The new research is based on dramatic images of a comet disintegrating in the sun's atmosphere last July. Comet Lovejoy grabbed headlines in Dec. 2011 when it plunged into the sun's atmosphere and emerged again relatively intact.  But it was not the first comet to graze the sun. Last summer a smaller comet...

Some Comets Like It Hot

[ Watch the Video ] Comets are icy and fragile. They spend most of their time orbiting through the dark outskirts of the solar system safe from destructive rays of intense sunlight.  The deepest cold is their natural habitat. Last November amateur astronomer Terry Lovejoy discovered a different kind of comet.  The icy fuzzball he spotted in the sky over his backyard observatory in Australia was heading almost directly for the sun.  On Dec. 16th, less than three weeks...

Comet Survives Close Encounter With Our Sun

[ Watch the Video ] On December 16, an armada of spacecraft witnessed something that many experts thought impossible.  Comet Lovejoy flew through the hot atmosphere of the sun and emerged intact. "It's absolutely astounding," says Karl Battams of the Naval Research Lab in Washington DC.  "I did not think the comet's icy core was big enough to survive plunging through the several million degree solar corona for close to an hour, but Comet Lovejoy is still with us." The...

The Beginning Of The End For Comet Lovejoy
2011-12-16 04:03:35

The SOHO spaceborne solar observatory today captured comet Lovejoy in its field of view for the first time, indicating that the icy body is on its final destructive plunge towards the Sun. Announced on 2 December, the newly discovered comet Lovejoy is on a near-collision course with the Sun and is expected to plunge to its fiery fate late on 15 December. At its closest approach, it will pass just 140 000 km above the solar surface. At that distance, the icy comet is not expected to...

Sungrazing Comet - Wrong Place, Wrong Time
2011-10-05 11:16:14

[ Watch the Video ] NASA's Solar And HelioSpheric Observatory (SOHO) recently witnessed a sungrazing comet being eaten up by a coronal mass ejection (CME). The comet that disintegrated on October 2, 2011 was a sungrazing comet of the type known as a Kreutz Sungrazer, according to NASA. The Kreutz Sungrazers are a family of comets known for taking orbits extremely close to the Sun.  This family is believed to be fragments of one large comet that broke up several centuries ago....

The sun has just experienced a storm"”not of explosive flares and hot plasma, but of icy comets. "The storm began on Dec 13th and ended on the 22nd," says Karl Battams of the Naval Research Lab in Washington, DC. "During that time, the Solar and Heliospheric Observatory (SOHO) detected 25 comets diving into the sun. It was crazy!" Sundiving comets"”a.k.a. "sungrazers""”are nothing new. SOHO typically sees one every few days, plunging inward and disintegrating as solar heat...

NASA scientists have spotted a comet in space being 'eaten' as it flies too close to the sun, Dailymail UK reported. Footage captured by NASA's solar-focused agency - Solar and Helioscopic Observatory (SOHO) - showed the Kreutz Sungrazer as it made its fateful approach. Click on "Related Video" above to see a video. Experts say Kreutz Sungrazers are characterized by orbits that take them extremely close to the Sun. German astronomer Heinrich Kreutz theorized that they are fragments of one...
