Researchers discover largest known fresh meteorite strike on Mars

[ad_1] Researchers have helped discover the largest fresh meteorite impact craters on Mars since NASA's Orbiter began scouring the planet. Since NASA's Mars Reconnaissance Orbiter began scouring the planet for them 16 years ago, Curtin University researchers have assisted in the discovery of the largest fresh meteorite impact craters on Mars, one of which contained ice at the lowest altitude ever observed. The two Curtin scientists were the only Australian representatives on a NASA-led international research team that helped make the rare discovery of two impact craters larger than 130 meters in diameter each that formed on Mars in the second half of 2021. Associate Professor Katarina Miljkovic, from Curtin's Space Science and Technology Centre and the School of Earth and Plan...

SHOCKING! Historic interstellar meteor CRASHED into Earth; NASA clocked it at 144000 kmph

[ad_1] The 2nd ever interstellar meteor that crashed into Earth was speeding at a shocking 144000 kmph, NASA shows. In 2014, a meteor was observed by NASA sensors. Back then, it wasn't thought to be of much importance apart from the fact that it was placed very far in the solar system. In 2019, NASA began looking for interstellar celestial bodies and the meteor, known as IM1, was confirmed to be the first ever interstellar meteor seen. For the unaware, interstellar celestial bodies are unique. They are any object from outer space that enters the solar system. These objects are very rare to spot since the Earth is placed in the inner circle of the solar system and asteroids and meteors don't come so close to the Sun. In fact, so far only one such space rock has been identified. Or so 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...
