A new federal study suggests that household dust containing a common flame retardant may be linked to an increase in cats getting sick from overactive thyroids. That could be a warning sign for how young children could get exposed to the chemical. picked by misswinkle 1 year ago

Dust has been a nuisance because it has obscured galaxies, and the stars within them, by absorbing the radiation they emit. But more recently dust has started to present opportunities because it emits radiation itself as a consequence of being heated up by nearby stars. Aided by new observing instruments and sophisticated computer software, this radiation enables astronomers to reconstruct what li... read full post picked by AutumnLotus 1 year ago

Explosions of small stars, long thought to create stellar dust, actually sweep dust away, scientists discovered. For years, researchers have observed swirling dust clouds around systems called recurring novas, which periodically explode. New images of a distant nova have now overturned astronomers' long-standing assumption that the dust originates in the blasts. picked by AutumnLotus 9 months ago

Newborn stars peek out from beneath their natal blanket of dust in this dynamic image of the Rho Ophiuchi dark cloud from NASA's Spitzer Space Telescope. Called "Rho Oph" by astronomers, it's one of the closest star-forming regions to our own solar system. Located near the constellations Scorpius and Ophiuchus, the nebula is about 407 light years away from Earth. picked by AutumnLotus 8 months ago

British scientists have unlocked one of the secrets behind how cancer spreads around the body. The breakthrough could help pave the way for a generation of drugs that would halt up to 90 per cent of cancers in their tracks. Such drugs could be particularly effective against breast and lung tumours - two of the biggest killers. picked by AutumnLotus 9 months ago

Dust littered the early universe and seeded the formation of rocky planets such as the Earth. Astronomers have found 10,000 Earth masses worth of dust surrounding Cassiopeia A, the remnants of a supernova about 11,000 light-years away from our planet. The NASA Spitzer Space Telescope observations show silicates, carbon, iron oxide, aluminum oxide and other dust-forming chemicals around the blown-o... read full post picked by AutumnLotus 10 months ago

Researchers have dated the earliest step in the formation of the solar system - when microscopic interstellar dust coalesced into mountain-sized chunks of rock - to 4,568 million years ago, within a range of about 2,080,000 years. The dates established by analyzing a particular type of meteorite, called a carbonaceous chondrite, which represents the oldest material left over from the formation of ... read full post picked by AutumnLotus 10 months ago

Here on Earth, no one pays much heed to dust or sand blasted out by a rocket launch because "atmospheric drag rapidly slows the lightweight particles so they fall harmlessly to the ground a few meters from the blast," he explains. But on the Moon? "There is no atmosphere to slow tiny particles." Small grit can travel enormous distances at high speeds, scouring everything in it... read full post picked by Maven 11 months ago
