Meteor shower to peak Saturday as Earth collides with Halley’s Comet debris

Meteor shower to peak Saturday as Earth collides with Halley’s Comet debris

Science
This weekend will feature the second meteor shower in as many weeks as Earth passes through a trail of debris left behind by one of the most well-known comets in recent history. The annual Eta Aquarid meteor shower will reach its peak on Saturday night into the early morning hours of Sunday, but the number of meteors visible to stargazers will depend on their location around the globe. "This shower happens to be one of, if not the best, showers in the Southern Hemisphere and is a moderate shower for the Northern Hemisphere," AccuWeather astronomy blogger Dave Samuhel said. "From the equator northward, they usually only produce medium rates of 10-30 per hour just before dawn," the International Meteor Organization said on its website. Meanwhile, those south of the equator can expect over ...

NASA detects atomic-force meteor explosion above the Bering Sea

Science
March 19 (UPI) -- According to NASA, a meteor exploded in Earth's atmosphere in December. The fireball exploded with a force 10 times that of the energy released by the atomic bomb dropped on Hiroshima -- the equivalent of 380 million pounds of TNT -- making it the second largest of its kind in the last 30 years. Only the Chelyabinsk meteor that exploded over southwest Russia six years ago, shattering the windows of local buildings, was larger. The Chelyabinsk blast was seen and heard by hundreds of people. Taxi cab dash cams recorded its approach. Because the latest explosion occurred over such a remote area -- Russia's Kamchatka peninsula -- the blast went unnoticed by the public. Lindley Johnson, planetary defense officer at NASA, told BBC News such a large explosion is only expected...

A meteor was the cause of an enormous explosion in the atmosphere last year, NASA has announced.The blast was 10 times more powerful than the atomic bomb dropped on Hiroshima. It was the second-largest such explosion in the last century, just behind the meteor which exploded over the Russian region of Chelyabinsk in 2013.The most recent meteor exploded over the Bering Sea, also near Russia.It was just 25.6km (16 miles) above the planet's surface and hurtling down at a steep angle of seven degrees when the friction of the atmosphere caused it to explode. The explosion was detected by US military satellites last year, and subsequently referred to NASA.According to NASA's planetary defence officer Lindley Johnson, the fireball exploded near to a common flight route, and so researchers...

A huge fireball exploded in the Earth's atmosphere in December, according to Nasa.The blast was the second largest of its kind in 30 years, and the biggest since the fireball over Chelyabinsk in Russia six years ago.But it went largely unnoticed until now because it blew up over the Bering Sea, off Russia's Kamchatka Peninsula.The space rock exploded with 10 times the energy released by the Hiroshima atomic bomb.Lindley Johnson, planetary defence officer at Nasa, told BBC News a fireball this big is only expected about two or three times every 100 years. What do we know?At about noon local time on 18 December, the asteroid barrelled through the atmosphere at a speed of 32km/s, on a steep traject...

The Perseid meteor shower dazzled spectators… again. The annual event takes place each year in early August. As the Earth passes through the debris left behind by the Swift-Tuttle comet's tail, an array of streaking lights is displayed across the night sky. Named for the constellation Perseus, because of where the meteors are viewed, the shower can be seen when looking toward the constellation in the northeastern portion of the sky between midnight and dawn.
