Ancient micrometeoroids carried specks of stardust, water to asteroid 4 Vesta

The formation of our solar system was a messy affair. Most of the material that existed before its formation—material formed around other, long-dead stars—was vaporized, then recondensed into new materials. But some grains of that material, formed before the sun’s birth, still persist. Source: https://phys.org/news/2020-06-ancient-micrometeoroids-specks-stardust-asteroid.html…

A new catalog of infrared dark clouds

Infrared dark clouds (IRDCs) are dark patches of cold dust and gas seen in the sky against the bright diffuse infrared glow of warm dust in our galaxy. These IRDCs, massive and rich in molecules, are natural sites for star birth—one of the main reasons why astronomers are actively studying them. IRDCs were first detected by two early space infrared missions,…

Did galactic crash trigger solar system formation?

Observations made with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed the telltale signs of a star system being born. Around the young star AB Aurigae lies a dense disc of dust and gas in which astronomers have spotted a prominent spiral structure with a ‘twist’ that marks the site where a planet may be forming. The observed…
