Astonishing discovery! 5 meteorites found in Antarctica; may contain secrets of Earth

[ad_1] Meteorites discovered in Antarctica could hold the key to unlocking the mystery of Earth’s formation. Here's what you need to know. One of the two polar ice caps on Earth, Antarctica is a desolate place known for its vast expanse of ice. The majority of the continent is covered in ice and snow, making it the coldest, windiest and driest continent on Earth. The conditions are so harsh on this continent that it maked it so inhospitable that no permanent human settlements exist here. Only researchers who work in temporary research stations are stationed here. Despite being inhospitable, Antarctica is home to a wide variety of unique ecosystems. Diverse array of microorganisms also exist here, with most of them trapped in the ice which is millions of years old.Now, scientists have ...

Space junk, not meteorites, remains biggest threat to spacecraft

[ad_1] Russian announced on Wednesday a February mission to the International Space Station to pick up crew members left stranded after a strike damaged the capsule that was to take them home. Dodging the kind of meteorite strike that forced Russia to plan a space station rescue mission is nearly impossible, yet the greater threat to spacecraft is actually the man-made debris in orbit, experts say.Russian announced on Wednesday a February mission to the International Space Station to pick up crew members left stranded after a strike damaged the capsule that was to take them home. Didier Schmitt, the European Space Agency's head of human and robotic exploration, said it was not rare for tiny meteorites to hit the space station. The micrometeorites can be travelling at speeds from 10 to...

Genius NASA gun to protect Mars Sample Return spacecraft by shooting down meteorites

[ad_1] NASA is preparing a meteorite protective measure for its Mars Sample Return spacecraft with the help of this gun. Spacecrafts are very advanced but highly sensitive vehicles which have to withstand the tremendous pressure of the vacuum in space. Although they are built to withstand the harsh conditions of outer space, they are still at a risk of being damaged by asteroids and meteorites. Even the smallest meteorite could damage the spacecraft enough to jeopardize the mission. NASA recently concluded its first planetary defense test to protect Earth against potential asteroid impacts. It seems like the space agency is planning the same strategy for its other spacecraft.NASA is currently testing a light-gas gun which hatter micrometeorite fragments and other space debris to prote...

This meteorite hit a car in New York!

[ad_1] Peekskill meteorite had slammed into a car back in 1992 with a speed of 14.16 kmps. Know what had happened. You must have seen a streak of light passing in the night sky a number of times. These so-called ‘shooting stars,” have different names depending on how they reach the Earth. NASA explains that meteorites are objects in space that range in size from dust grains to small asteroids. Consider them as “space rocks." Occasionally, these space rocks enter Earth's atmosphere to burn up and they can be seen as fireballs or “shooting stars”, which are known as meteors. However, in case, a meteoroid survives the travel through the atmosphere and hits the ground on Earth then it's called a meteorite, NASA explained. But do you know, there is a famous Meteorite named Peekskill w...

These mysterious meteorites on Earth spawned by GIGANTIC 6561-foot asteroid?

[ad_1] Dark veined meteorites are a big space mystery. But researchers believe they came from a dangerous asteroid. In February 2013, a meteorite exploded over the city of Chelyabinsk, Russia and rained small pebbles all over the streets. These broken down pieces of the meteorite had a strange and mysterious pattern on them. They were covered in thin dark stripes. This had confused the scientists for a long time because meteorite remains can come in different colors due to the composition of the particles, but they never appear with stripes. After studying the event and finding more examples of it in space, it was revealed that this was caused due to a process called shock darkening but it was not understood why this did not happen to other meteorite remains. Notably, this confusing q...

Touch the skies! NASA scientist hot in hunt for fiery meteorite that crashed to Earth

[ad_1] NASA scientist has literally taken to the sky to track the meteorite that tore through Utah. Weeks after a fiery meteorite into Earth, a scientist from NASA has taken to the skies to track down the path of the meteorite. The meteorite had crashed in Utah. Peter Jenniskens boarded a KSL-TV chopper to look for a hole in the ground where the meteorite hit the earth. He said, “"We're literally looking for a hole in the ground, yeah, because the soil here is fairly soft and it looks like the rocks are just punching through." The empty hole that Jenniskens did discover shows no evidence of the rock, but the information will help Jenniskens in tracking the details as he said, “So, it does look like something was dug out here,...

Almost 10,000 meteorites hit Earth every year

[ad_1] How many meteorites hit Earth every year? Fewer than 10,000, but is it dangerous for living organisms? Find it out here. Have you seen a shooting star? Well these are not exactly stars but are burning rocks from space that enter the Earth's atmosphere. According to the information provided by the American Meteor Society (AMS), Meteoroids are the smallest members of the solar system and whenever a meteoroid plows into the Earth's atmosphere, it will create a brief flash of moving light in the sky, called a meteor (which appears to be a shooting stars). If remnants of the parent meteoroid survive the trip through the atmosphere to reach the ground, then these remnants are called meteorites. But how many meteorites hit t...
