Considering the recent Meteorite that struck Russia…could this be somehow related to the undiscovered Comet?

A surprise meteor shower spotted in February was likely caused by cosmic “bread crumbs” dropped by an undiscovered comet that could potentially pose a threat to Earth, astronomers announced today (July 27).
The tiny meteoroids that streaked through Earth’s atmosphere for a few hours on Feb. 4 represent a previously unknown meteor shower, researchers said. The “shooting stars” arrived from the direction of the star Eta Draconis, so the shower is called the February Eta Draconids, or FEDs for short.
The bits of debris appear to have been shed by a long-period comet. Long-period comets whiz by the sun very infrequently, so it’s tough to

Earth Collided Head-On With Comet In January

Night turned briefly into day over a wide area in California and Nevada at 5:21:44 a.m. PST on Thursday morning January 17th, creating hopes of another extraterrestrial surprise delivery of meteorites, but this bright fireball did not drop meteorites on the ground. This was a head-on collision with a small perhaps 1-meter sized comet, rather than the glancing blow of a stronger asteroid. The comet matter was almost instantly turned into dust and gas.

Comet Lovejoy Survives Fiery Plunge Through Sun, NASA Says

Comet Lovejoy plunged through the sun’s corona at about 7 p.m. EST today (midnight GMT on Dec. 16), coming within 87,000 miles (140,000 kilometers) of our star’s surface. Temperatures in the corona can reach 2 million degrees Fahrenheit (1.1 million degrees Celsius), so most researchers expected the icy wanderer to be completely destroyed.But Lovejoy proved to be made of tough stuff. A video taken by NASA’s Solar Dynamics Observatory (SDO) spacecraft showed the icy object emerging from behind the sun and zipping back off into space.
“Breaking News! Lovejoy lives! The comet Lovejoy has survived its journey around the sun to reemerge on the other side,” SDO researchers tweeted today.
SDO is one of many instruments that scientists — eager to record and study the comet’s presumed demise — trained on Lovejoy as it streaked toward the sun.
“We have here an exceptionally rare opportunity to observe the complete vaporization of a relatively large comet, and we have approximately 18 instruments on five different Read more…
Two Comets to Pass Close to Earth in Early October
As mentioned before in previous blogs, Comet Elenin will pass close to Earth in six weeks or so. We had previously talked about the theories out there with this comet. To read them, please click here and here.
For even better treat, on Oct. 7, Comet Honda will brighten to a magnitude 5 in the constellation Leo and favor a horizon view before sunrise for Northern sky observers.
That is not all, Comet Honda will join Comet Elenin, and both will be visible on that morning in the same wide field of view in binoculars and camera lenses, a rare treat with two comets at once! You should be able to get some spectacular photos of this event. I will have to remind you as we get closer to the event so that you can post some pictures for me.

Comet’s Death by Sun Photographed for First Time
 |
| The Solar Dynamics Observatory AIA imager (observing in extreme ultraviolet light) actually spotted a sun-grazing comet as it disintegrated over about a 15 minute period (July 6, 2011), something never observed before. The angle of the comet’s orbit brought it across the front half of the Sun. Given the intense heat and radiation, the comet simply evaporated away completely. The comet was probably a member of the Kreutz sun-grazer family. CREDIT: NASA/SDO/AIA |
The death of a comet that plunged into the sun was captured on camera this month for the first time in history, scientists say.
The comet met its fiery demise on July 6 when it zoomed in from behind the sun and melted into oblivion as it crashed into the star. It was NASA’s Solar Dynamics Observatory (SDO), a satellite orbiting Earth that studies the sun, which witnessed the comet’s death-blow.
One of the SDO spacecraft’s high-definition imagers “actually spotted a sun-grazing comet as it disintegrated over about a 15 minute period (July 6, 2011), something never observed Read more…
New Mineral (Wassonite)Found in Antarctic Meteorite
A meteorite discovered in Antarctica in 1969 has just divulged a modern secret: a new mineral, now called Wassonite.The new mineral found in the 4.5-billion-year-old meteorite was tiny — less than one-hundredth as wide as a human hair. Still, that was enough to excite the researchers who announced the discovery Tuesday (April 5).
“Wassonite is a mineral formed from only two elements, sulfur and titanium, yet it possesses a unique crystal structure that has not been previously observed in nature,” NASA space scientist Keiko Nakamura-Messenger said in a statement.
The mineral’s name, approved by the International Mineralogical Association, honors John T. Wasson, a UCLA professor known for his achievements across a broad swath of meteorite and impact research.
Grains of Wassonite were analyzed from the meteorite that has been officially designated Yamato 691 enstatite chondrite. Chondrites are primitive meteorites that scientists think Read more…
