Tracking a mysterious group of asteroid outcasts

High above the plane of our solar system, near the asteroid-rich abyss between Mars and Jupiter, scientists have found a unique family of space rocks. These interplanetary oddballs are the Euphrosyne (pronounced you-FROH-seh-nee) asteroids, and by any measure they have been distant, dark and mysterious — until now.

Distributed at the outer edge of the asteroid belt, the Euphrosynes have an unusual orbital path that juts well above the ecliptic, the equator of the solar system. The asteroid after which they are named, Euphrosyne — for an ancient Greek goddess of mirth — is about 156 miles (260 kilometers) across and is one of the 10 largest asteroids in the main belt. Current-day Euphrosyne is thought to be a remnant of a massive collision about 700 million years ago that formed the family of smaller asteroids bearing its name. Scientists think this event was one of the last great collisions in the solar system.

A new study conducted by scientists at NASA's Jet Propulsion Laboratory in Pasadena, California, used the agency's orbiting Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) telescope to look at these unusual asteroids to learn more about Near Earth Objects, or NEOs, and their potential threat to Earth.

NEOs are bodies whose orbits around the sun approach the orbit of Earth; this population is short-lived on astronomical timescales and is fed by other reservoirs of bodies in our solar system. As they orbit the sun, NEOs can occasionally have close approaches to Earth. For this reason alone — the safety of our home planet — the study of such objects is important.

Meteor explosion caught on camera in Santa Cruz, California

Image
While shooting some timelapses, we saw a huge bright flash in the sky. It even lit up the entire ground. We looked up and saw a huge streak across the sky of burning dust.

I did the calculations and the dust fell from the sky for at least 50 frames of my timelapse. Each exposure was 15 seconds long, so that means the burning dust fell for 12.5 minutes. CRAZY!!! This was shot at Shark Fin Cove just north of Santa Cruz on July 21st, 2015 by @PermaGrinFilms.

Meteor captured streaking through Jervis Bay sky, Australia

It’s not every day you get to see, let alone photograph, bioluminescence and then throw a meteor into the equation. But that is what Vincentia photographer Maree Clout has managed to capture.
Up in the sky, it's a bird, it's a plane, no, it's a meteor.

And let's just throw in a bit of bioluminescence for good measure.

That's exactly what Vincentia photographer Maree Clout managed to capture at Jervis Bay last Wednesday night.

Along with Corinne Le Gall, whose superb photograph of bioluminescence on display in Jervis Bay featured in Wednesday's South Coast Register, Ms Clout spent three nights last week trying to capture the natural phenomenon.

During one of her 15-second exposures Ms Clout also managed to capture a meteor among the star laden night sky.

Cometary fragment crossing the atmosphere (archive).
A comet has exploded over the province of Cuenca and fragments of it have been seen from one of Spain's largest observatories in Toledo.

Scientists at the La Hita complex say comet number 169P/NEAT, which flew over the central region of Castilla-La Mancha on Wednesday night and the early hours of Thursday morning burnt out in the sky 79 kilometres above ground over the town of Cañamares.

Shards of rock plummeted downwards at a speed of 80,000 kilometres per hour and broke up when they hit the earth's atmosphere in a violent impact that turned them into bright balls of fire.

This was first seen at 23.50hrs mainland Spain time above Portugal and, at 00.07hrs, the largest and fastest fragment impacted with the atmosphere above the province of Málaga on the south coast, creating a fireball as bright as the moon.

Over two dozen witnesses reported a bright, slow moving fireball over central Texas last night slightly after 9:00 PM local time. Most reports were clustered around Austin and San Antonio. An analysis of the witness reports estimates that the fireball was traveling from the south to the north just west of San Antonio.

A Potteries star-gazer captured the moment a meteor lit up the skies across North Staffordshire.

Martin Kessel captured the object as it flew over Weston Coyney in the early hours of Thursday morning.

The former Newcastle-under-Lyme High School pupil has a camera set up to monitor the skies over Stoke-on-Trent - in the hope of capturing activity in the atmosphere and beyond.

And Martin was in luck, posting the video on his Youtube channel, where he described it as 'large, very bright meteor or fireball' which passed over at 2.02am.

Vietnam, Laos investigating mysterious light followed by explosion

A strange streak of light flashes in the sky near the border between Vietnam and Laos on July 8, 2015.
Vietnamese officials are cooperating with colleagues in Laos to identify what created a streak of light in the sky and a big explosion sound after that around the border area on Wednesday night.

As of Thursday afternoon, border guard forces still have not identified the cause of the phenomenon. An army representative has ruled out the possibility of an air crash. Vo Van Tuan, deputy chief commander of Vietnam's army, said there has been no report of any issue with a civil or military flight in the area at the time.

Tuan said a piece of space debris could have burned up, causing the light and the explosion. Locals spotted the strange light flashing at around 9 p.m., then something fell and exploded. Curiosity caused heavy traffic jams stretching two kilometers along a national highway in Ha Tinh Province. Dang Vu Tuan Son, head of the Vietnam Astronomy and Cosmology Association, told Nguoi Lao Dong (Laborer) newspaper that the item was more likely a meteor than space junk. Son said space junk is usually small and would not cause such a big explosion.

"But we have to find the debris to know exactly what it was."
