Total Solar Eclipse – March 8, 2016

detailed total eclipse

Those lucky enough to be in parts of Southeast Asia will be able to see a total solar eclipse on Tuesday, March 8, 2016 between the hours of 2300 and 2600 GMT (6 and 9 p.m. EST) with the period of totality between 2538 and 2542 GMT (8:38 and 8:42 p.m EST). The area of totality will be a nearly 100-mile wide path shown above.

Everyone else can view the event on Slooh.com. Twitter viewers can ask questions using the hashtag #SloohEclipse.

Meteor Explodes over the Ural Mountains in Russia

At about 9:20am local time (5:20am GMT), a meteor entered the Earth’s atmosphere and exploded above the Ural Mountains in Russia, injuring more than 900 people. The injuries were mostly due to ear drum damage, broken glass, and other debris caused by a shock-wave.

“Fragments of the meteor fell in a thinly populated area of the Chelyabinsk region, the Russian Emergency Ministry said in a statement. Authorities in Chelyabinsk said the blast had been heard at an altitude of 10,000 metres (32,800ft), suggesting it occurred when the meteor or meteors entered the earth’s atmosphere” (Source: http://www.guardian.co.uk/science/2013/feb/15/meteorite-explodes-over-russian-urals-live-updates).

When the asteroid hit the earth’s atmosphere, it was going so fast that it was as if it hit a brick wall. The subsequent explosion caused at least one shockwave (there may have been more than one explosion from fragments) and that’s what caused the damage. The damage included more than smashed windows. It buckled shop fronts, set off car alarms, disrupted mobile phone signals, and a wall was damaged at the Chelyabinsk Zinc Plant as seen in the video.

Connected to  Asteroid 2012 DA14?

(What is Asteroid 2012 DA14? See previous posts Asteroid 2012DA14 to Shoot through Near Earth Orbit and Asteroid 2012DA14 – Update.)

This meteor does not seem to be connected to Asteroid 2012 DA14. The Earth travels 66,611 miles in its orbit every hour, so the Earth was 932,554 miles away from tonight’s encounter with asteroid 2012 DA14 – almost four times the distance between the Earth and the Moon. It is unlikely that this meteor wA Taste of Earth - Coveras a fragment of 2012 DA14.

REPOST: What would happen if 2012DA14 were not an asteroid, but a probe from another solar system? Of course,it isn’t, but this possibility is explored in my science fiction short story, A Taste of Earth (available free on Amazon, Smashwords, Barnes & Noble, Kobo, and others).

Did You Miss It?

Since this post is my most popular to date (next to The Standard Model in Layman’s Terms), as a public service it should be updated.

Depending on when you read this, Space.com may not be showing it any more.

Asteroid 2012 DA14 has already made its closest pass of Earth, but live video will be streamed from other telescopes as the Earth turns and as the asteroid flies off on its orbit around the sun.

5 p.m. ET (10 p.m. GMT): The Virtual Telescope Project 2.0 will present live video of the asteroid flyby from a telescope in Italy, weather permitting. Video site: Watch Virtual Telescope Project’s webcast.

6 p.m. ET (11 p.m. GMT): Weather permitting, the Clay Center Observatory in Massachusetts will stream real-time, high-definition video from 6 p.m. ET until 4 a.m. ET Saturday. Watch Clay Center video on Ustream.

9 p.m. ET (2 a.m. GMT): Slooh Space Camera plans to present several live shows about the asteroid flyby, accompanied by expert commentary. Weather permitting, imagery will be beamed to Slooh HQ from telescopes on the Canary Islands and in Arizona. Watch the show on Slooh.com.

9 p.m. ET (2 a.m. GMT): A video feed of the flyby from a telescope at NASA’s Marshall Space Flight Center will be streamed for three hours. During the live-streaming event, viewers can ask researchers questions about the flyby via Twitter or the Ustream chat window. Watch Marshall’s Ustream channel.

Asteroid 2012DA14 to Shoot through Near Earth Orbit

NASA has projected that on February 15, 2013, an asteroid about half the size of a football field will skim by Earth within near earth orbit.

nasa_2012DA14_projected_path

What:

asteroid

Designation:

2012DA14

Composition:

probably made of stone as opposed to ice or metal

Size:

about 148 feet (45 meters) long, “medium size,” about half the size of a football field

Weight:

roughly 143,000 tons

Speed:

traveling at a speed equal to twice the width of a full moon every minute

Size:

about half the size of a football field

When:

closes to Earth on Feb. 15

Where:

·         17,200 miles above our planet’s surface

·         through low earth orbit

·         closer than man-made satellites that power GPS

·         where the International Space Station and many earth observation satellites are located


“This is a record-setting close approach,” Don Yeomans of NASA’s Near Earth Object Program at JPL said in a video released by NASA this week.  “It will come interestingly close, closer than many man-made satellites. The odds of impact with a satellite are extremely remote.”

Don Yeomans is also the author of Near-Earth Objects: Finding Them Before They Find Us. He compared the asteroid to the one that leveled hundreds of square miles of Siberian forest in the “Tunguska Event” in 1908. He noted that even if DA14 did strike the planet, the impact wouldn’t be cataclysmic, unless, of course, you happened to be near it. A similar sized object created a mile wide crater in Arizona. That one was made of iron, which made it an especially potent impactor and devastated the area 50 miles around the impact site.
