Preliminary trajectory
A fireball in the sky above the Pacific Northwest led dozens of people to report sightings to the American Meteor Society on Wednesday. The FOX 12 newsroom started receiving reports of a bright light flashing across the sky around 6 a.m. Wednesday.

AMS experts said it appears the decent-sized meteor entered the Earth's atmosphere in Washington state, traveled in an east-to-west direction and landed in the Pacific Ocean. "It went from one horizon to the other, never fading," said one witness. A report out of Tigard said it "traveled east to west across the entire visible sky - very long."

Another witness, out of Gladstone, described it as "the longest lasting shooting star I've ever seen."

There were also reported sightings in British Columbia, Alberta, Montana and Washington. Because of cloud cover in the Seattle area, there were very few reported sightings there. Experts at OMSI say a fireball is another term for a very bright meteor, generally brighter than magnitude -4, which is about the same magnitude of the planet Venus in the morning or evening sky.

Paying lip service to the cosmic threat: UN votes to 'fight' asteroids by creating 'global warning network'... maybe

Even the United Nations is taking the threat of asteroids hitting our planet seriously. Last week, the U.N. General Assembly approved measures to coordinate detection and response to asteroid strikes that could level cities and possibly destroy our civilization.

Specifically, the agency voted to create an International Asteroid Warning Network made up of scientists, observatories and space agencies around the planet to share information about newly discovered asteroids and how likely they are to impact Earth. The group will also work with disaster relief organizations to help them determine the best response to an asteroid impact like the one that rattled the Russian city of Chelyabinsk in February. The U.N. will also set up a space mission planning advisory group to look into how humans might deflect an asteroid heading our way -- the best options, the costs and the technologies needed. The results of that study will be shared with space agencies throughout the world.

The General Assembly also agreed that the existing U.N. Committee on the Peaceful Uses of Outer Space would monitor threats from asteroids and help plan and authorize a deflection campaign if necessary.

Comment: Given the current state of the world, humans voting on pooling resources to deflect asteroids is like ants voting to prevent the boulders rolling down the hill from hitting their colony. And these UN diplomats might even realise this on some level. They can say all the things they want, vote endlessly on measures everyone should take, but at this point it's far too late. Practical, physical technologies should have already been developed, tested and worked out.

But no! Instead they had wars to fight and money to make... to hell with protecting and advancing the welfare of mankind.

In Space - November 19: This image taken with a meteorite tracking device developed by George Varros, shows a meteorite as it enters Earth's atmosphere during the Leonid meteor shower November 19, 2002. The device, which is deployed on board a NASA DC-8, tracks and photographs meteorites.
Several people in the Portland Metro area reported seeing a fireball in the sky Wednesday morning, moving east to west.

Three different viewers contacted KGW to say they had seen it just before 6 a.m.

"I was out walking my dog this morning around 5:55 a.m. and saw what looked like someone lit a tennis ball on fire and threw it," viewer John Kisling said. "It took a couple seconds to traverse the sky."

An expert told KGW it was a piece of an asteroid burning up when it hit the atmosphere.

"Fireballs are not uncommon," said Dick Pugh of the Portland State University Meteorite Labratory. "The question is: Did it make it all the way down?"


Comment: No, the question is: why are they now common?

This illustration shows the trajectory of asteroid 2013 UV3, in blue, as it flies by Earth.
A space rock the size of a tractor-trailer is set to fly harmlessly by Earth today (Oct. 29), zipping between our planet and the moon.

"Small asteroid 2013 UV3 will safely pass Earth Oct. 29," reads a Twitter post from NASA's Near-Earth Object Program (@AsteroidWatch), based at the agency's Jet Propulsion Laboratory (JPL) in Pasadena, Calif.

The space rock was first observed just a few days ago, on Oct. 25, according to data from JPL. The asteroid's path, illustrated in this video animation, (below) will bring it inside the orbit of the moon, which typically circles Earth from a distance of about 239,000 miles (384,600 kilometers).

Paleontologist presents origin of life theory

Origin of Life Theory

Most researchers believe that life originated in deep-sea hydrothermal vents. About 4 billion years ago, Earth was a watery planet; ocean stretched from pole to pole; any life synthesis would be dilated. It needed a protected basin.
It has baffled humans for millennia: how did life begin on planet Earth? Now, new research from a Texas Tech University paleontologist suggests it may have rained from the skies and started in the bowels of hell.

Sankar Chatterjee, Horn Professor of Geosciences and curator of paleontology at The Museum of Texas Tech University believes he has found the answer by connecting theories on chemical evolution with evidence related to our planet's early geology.

"This is bigger than finding any dinosaur," Chatterjee said. "This is what we've all searched for - the Holy Grail of science."

Thanks to regular and heavy comet and meteorite bombardment of Earth's surface during its formative years 4 billion years ago, the large craters left behind not only contained water and the basic chemical building blocks for life, but also became the perfect crucible to concentrate and cook these chemicals to create the first simple organisms.

He will present his findings Oct. 30 during the 125th Anniversary Annual Meeting of the Geological Society of America in Denver.

As well as discovering how ancient animals flew, Chatterjee discovered the Shiva Meteorite Crater, which was created by a 25-mile-wide meteorite that struck off the coast of India. This research concluded this giant meteorite wreaked havoc simultaneously with the Chicxulub meteorite strike near Mexico, finishing the dinosaurs 65 million years ago.

Ironically, Chatterjee's latest research suggests meteorites can be givers of life as well as takers. He said that meteor and comet strikes likely brought the ingredients and created the right conditions for life on our planet. By studying three sites containing the world's oldest fossils, he believes he knows how the first single-celled organisms formed in hydrothermal crater basins.

"When the Earth formed some 4.5 billion years ago, it was a sterile planet inhospitable to living organisms," Chatterjee said. "It was a seething cauldron of erupting volcanoes, raining meteors and hot, noxious gasses. One billion years later, it was a placid, watery planet teeming with microbial life - the ancestors to all living things."

27 fireballs recorded over U.S. on 26 October 2013

Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics. Daily results are presented here on Spaceweather.com.

On Oct. 26, 2013, the network reported 27 fireballs.
(16 sporadics, 7 Orionids, 1 Leonis Minorid, 1 epsilon Geminid, 1 Southern Taurid, 1 xi Draconid)

A large, vibrant meteor lit up sky over Liberal early this morning, and one man who witnessed the meteor was impressed.

While dodging traffic turning into National Beef's north entrance at Eighth Street and U.S. Highway 54 this morning, Leader & Times Managing Editor Larry Phillips witnessed a large meteorite streaking through the sky just west of Liberal.

"Just as I was coming into town - at 65 mph - as always, two eastbound cars turned right in front of me onto Eighth Street," Phillips said. "I hit my bright lights and my brakes.

"As I passed the intersection just behind the second car turning in, I caught a large white light out of my peripheral vision in my upper right side of the windshield," he continued. "It was too large and moving too fast to be a plane, and then a large tail started developing, and I knew it was a meteor.

Meteor spotted shooting across the Colorado sky


A meteor shot across the sky Thursday morning.

Chris Peterson, who works at the Cloudbait Observatory, said after comparing two videos, he believes it began over Mead and ended over Yuma.

It traveled about 125 mi. and the height was about 28 mi. Peterson estimates the meteor's speed to about 35,000 mph.

While that sounds fast to some, it classifies the meteor as a low, slow meteor, which will most likely to drop meteorites.

Peterson also said this meteor is not part of the Orionid meteor shower, which peaked a few days ago and still has some minor activity.

This is a sporadic meteor that's unassociated with any other showers.

The largest-discovered fragment of a Russian meteorite, weighing around 570 kilograms, has been lifted from the bed of Lake Chebarkul in the Urals.

The huge meteorite chunk split into three pieces when scientists tried to weigh it. The precise weight could not be established because the heavy object broke the scales.

"The preliminary examination... shows that this is really a fraction of the Chelyabinsk meteorite. It's got thick burn-off, the rust is clearly seen and it's got a big number of indents. This chunk is most probably one of the top ten biggest meteorite fragments ever found," said Sergey Zamozdra, associate professor of Chelyabinsk State University, as cited by Interfax news agency.

He explained that it was important to establish the weight of the fragment in order to learn more about the qualities of the whole of the meteorite.

The lifted chunk was taken to the regional natural history museum. The plan is to have a small sample of it X-rayed to determine what minerals it consists of.
