    The American Meteor Society (AMS) took to Twitter on December 7 to confirm that what he saw was in fact, a meteor. AMS received reports from 146 people about the fireball event. The society noted it was primarily visible from Pennsylvania, but eyewitness accounts were also reported from twelve other states: New York, Maryland, Virginia, Ohio, Delaware, Connecticut, New Jersey, Rhode Island, West Virginia, New Hampshire, Massachusetts and Washington, DC.

    Asteroid Florence will pass by Earth on Sept. 1, 2017, at a distance of 4.4 million miles (7 million kilometers). Image Credit: NASA / JPL-Caltech A large rock will fly past Earth on Sept. 1, 2017, at a distance of 4.4 million miles (7 million kilometers). Asteroid 3122 Florence, named after modern nursing founder Florence Nightingale, is the largest object to make a close-encounter since NASA began tracking near-Earth objects (NEO) in the 1990s. “While many known asteroids have passed by closer to Earth than Florence will on Sept. 1, all of those were estimated to be smaller,” said Paul...

    Radar images obtained between August 29 and September 1, when Florence came closest to Earth, reveal that the asteroid is about 2.8 miles (4.5 kilometers) in size, the US space agency said. It said the two moons were probably between 300-1,000 feet (100-300 meters) across. The inner moon takes approximately eight hours to revolve around Florence while the outer moon takes between 22 and 27 hours, NASA said. NASA said the radar images of Florence, which was discovered in 1981, were obtained by the Goldstone Deep Space Communications Complex in California.

    A MASSIVE asteroid that could have destroyed New York City skimmed past Earth – and NASA had no clue. The large space rock – dubbed 2017 VL2 – passed the planet on November 9 at an astonishing distance of just 73,000 miles, which is considered tiny in space terms. Space boffins think that if the rock measuring between 16 and 32 metres had hit, it could’ve wiped a major city such as New York off the map. The rock belongs to the Apollo group of asteroids and was first seen at ATLAS-MLO observatory in Hawaii a day later. It was...

    Upsurge in big earthquakes predicted for 2018 as Earth rotation slows Scientists say number of severe quakes is likely to rise strongly next year because of a periodic slowing of the Earth’s rotation Scientists have warned there could be a big increase in numbers of devastating earthquakes around the world next year. They believe variations in the speed of Earth’s rotation could trigger intense seismic activity, particularly in heavily populated tropical regions. Although such fluctuations in rotation are small – changing the length of the day by a millisecond – they could still be implicated in the release of vast...

    The world’s earliest alphabet, inscribed on stone slabs at several Egyptian sites, was an early form of Hebrew, a controversial new analysis concludes. Israelites living in Egypt transformed that civilization’s hieroglyphics into Hebrew 1.0 more than 3,800 years ago, at a time when the Old Testament describes Jews living in Egypt, says archaeologist and epigrapher Douglas Petrovich of Wilfrid Laurier University in Waterloo, Canada. Hebrew speakers seeking a way to communicate in writing with other Egyptian Jews simplified the pharaohs’ complex hieroglyphic writing system into 22 alphabetic letters, Petrovich proposed on November 17 at the annual meeting of the American...

    A gigantic space rock called 3200 Phaethon is due to brush ‘quite close’ to our planet on December 17, Russian astronomers have revealed. This huge asteroid is thought to cause the beautiful Geminids meteor shower which will take place between December 13 and 14, causing hundreds of bright meteors to illuminate the night sky as they burn up in Earth’s atmosphere. But NASA has also described it as a ‘potentially hazardous asteroid whose path misses Earth’s orbit by only 2 million miles‘ – which is tiny in galactic terms. It’s about half the size of Chicxulub, the rock which wiped...

    To recap, when `Oumuamua was first observed on October 19th, 2017, by astronomers using the University of Hawaii’s Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), the object (then known as C/2017 U1) was initially believed to be a comet. However, subsequent observations revealed that it was actually an asteroid and it was renamed 1I/2017 U1 (or 1I/`Oumuamua). Follow-up observations made using the ESO’s Very Large Telescope (VLT) were able to place constraints on the asteroid’s size, brightness, composition, color and orbit. These revealed that `Oumuamua measured some 400 meters (1312 feet) long, is very elongated, and spins on its axis...

    Yet another Jovian fireball? On May 26th, amateur astronomers recorded a rare impact flash in Jupiter's north polar region. Jupiter just got beaned for the sixth time (that we know about)! On the evening of May 26th, between 19:24.6 and 19:26.2 Universal Time, Sauveur Pedranghelu, a French amateur from Corsica, detected an impact flash live on video in Jupiter's north polar region. The flash was very brief, lasting only about 0.7 second, and displayed two brightness peaks. A bright dot — about the size of Europa when seen in transit — marked the site of impact at latitude 51° north...

    Every object in our Solar System that takes the plunge from out beyond Neptune to our inner reaches, where the rocky planets lie, will become a comet. As it nears the Sun, its ices melt, creating the tails we associate with them, and also creating a debris path that can create meteor showers if they cross Earth's orbit. For thousands of years, the most consistent, spectacular meteor shower has been the Perseids, created by Comet 109P/Swift-Tuttle. At its incredibly large size (26 kilometers across) and speed, it contains nearly 30 times the energy of the asteroid strike that wiped out...

    Astronomers around the world are trying to track down a small, fast-moving object that is zipping through our solar system. Is a comet? An asteroid? NASA's not sure. The space agency doesn't even know where it came from, but it's not behaving like the local space rocks and that means it may not be from our solar system. If that's confirmed, NASA says "it would be the first interstellar object to be observed and confirmed by astronomers." NASA says astronomers are pointing telescopes on the ground and in space at the object to get that data. For now, the object...

    The IAU also approved an official scientific designation for 'Oumuamua: 1I/2017 U1. This is a first-of-its-kind moniker; the "I" stands for "interstellar." Previously, small objects like 'Oumuamua have received standard comet or asteroid designations, which sport a "C" or "A," respectively, in place of the "I." 'Oumuamua was first spotted on Oct. 19, by astronomers using the Pan-STARRS1 telescope in Hawaii. The smallish object was first classified as a comet but then regarded as an asteroid, after further observations revealed no evidence of a coma (the fuzzy cloud of gas and dust that surrounds a comet's core). Analysis of 'Oumuamua's trajectory soon...

    To date, every comet humanity has seen inside the Solar System has come from the Solar System, whether it's the Kuiper Belt or the billions of comets believed to make up the Oort Cloud. Now, however, it looks like astronomers might have found a comet of interstellar origin. They've used Hawaii's Pan-STARRS 1 telescope to track C/2017 U1, an object with a very eccentric, hyperbolic orbit (that is, moving quickly enough to escape gravitational pull) that wasn't connected to the Sun. The trajectory suggests that it's a comet which escaped from a nearby star, rather than something knocked out a...

    Now, new data reveal the interstellar interloper to be a rocky, cigar-shaped object with a somewhat reddish hue. The asteroid, named ‘Oumuamua by its discoverers, is up to one-quarter mile (400 meters) long and highly-elongated—perhaps 10 times as long as it is wide. That aspect ratio is greater than that of any asteroid or comet observed in our solar system to date. While its elongated shape is quite surprising, and unlike asteroids seen in our solar system, it may provide new clues into how other solar systems formed. The observations and analyses were funded in part by NASA and appear...

    The site of what is now Rotterdam's Yangtzehaven was inhabited by humans in the Middle Stone Age. At a depth of 20 metres, in the sea bed, unique underwater archaeological investigation found traces of bone, flint and charcoal from around 7000 BC. These finds are the very first scientific proof that humans lived at this spot in the Early and Middle Stone Age. Up to now, very little was known about this period in particular, the Early and Middle Mesolithic, so far to the west of the Netherlands...
