New evidence shows how an asteroid dust cloud triggered new life on Earth 470 meters ago Science

Astronomers have found fascinating evidence that millions of years ago an asteroid covered the earth with dust. The event dramatically cooled the planet and triggered an ice age, followed by a significant increase in new species. The work, led by Birger Schmitz of the University of Lund in Sweden, was recently published in Science Advances [veröffentlicht19659003] and provides new insights …

Twin Baby Stars Caught Feeding From Their Mother, A Twisted 'Pretzel' Of Interstellar Dust

Twin baby stars are nestled inside a "pretzel" of glowing gas and dust in a never-before-seen image captured by the Atacama Large Millimeter / submillimeter Array (ALMA) radio telescope located in northern Chile's Atacama Desert. ALMA spotted the twisted display in the Nebula Pipe. Also known as Barnard 59, this immense dark cloud of interstellar dust lies near the center …

Asteroid dust could fix global warming, scientists say

WASHINGTON – A group of Swedish researchers believe that a catastrophic asteroid collision of hundreds of millions of years ago could have the answer to the solution of climate change. The international study investigates the consequences after a huge asteroid was crushed between Jupiter and Mars and large amounts of dust were sent through the solar system. The dust had …

Asteroid dust could have triggered a massive explosion of life on Earth 466 million years ago

Nearly half a billion years ago, there was a tremendous explosion of species development on Earth that dramatically increased the biodiversity of animals – but the true cause of this event has remained a mystery. A New Release Scientists, published Wednesday in Science Advances, show that the beginning of the event coincided with the largest documented asteroid crash in the …

For an asteroid, Ryugu has surprisingly little dust on its surface

Ryugu is a decent freak. The surface of the small near-Earth asteroid is surprisingly dust-free, observations from the German MASCOT Lander Show. The asteroid, thought The dissolution of a larger body has created around 700 million years Has no atmosphere to protect it from interplanetary dust flowing through the solar system ( SN: 4/27/19, p. 4 ). These miniature rockets …

Fresh interstellar dust discovered in the snow of the Antarctic

Investigating snow in the Antarctic, researchers first discovered interstellar dust that recently fell to Earth. These results could shed light on the mysterious interstellar clouds. The solar system flies regularly, scientists said. Tons of extraterrestrial dust caused by passing comets, asteroid collisions, and exploding stars fall to the ground daily. However, scientists may not find it until long after the …

Radioactive dust from an old supernova is buried in the Antarctic

Splash Damage Radioactive dust from a supernova landed in the Antarctic from a star that exploded millions of years ago into a supernova, where it was finally buried under countless thousands of pounds of snow. After a massive excavation effort, scientists hope the study of dust reveals new secrets about the cosmic environment of our solar system, said lead researcher …
