Latest Space dust Stories
Using the Very Large Telescope Interferometer in near-infrared light, a team of astronomers observed 92 nearby stars to probe exozodiacal light from hot dust close to their habitable zones and combined the new data with earlier observations.
Current theories suggest that rocky planets like Earth start their lives as microscopic bits of dust tinier than a grain of sand. However, astronomers have recently discovered that filaments of star-forming gas near the Orion Nebula might be full of pebble-sized particles.
Seven rare and microscopic particles of space dust collected by instruments onboard NASA’s Stardust mission could be the first samples of contemporary interstellar dust ever obtained by scientists.
A team of scientists at NASA's Ames Research Center has successfully reproduced, right here on Earth, the processes that occur in the atmosphere of a red giant star and lead to the formation of planet-forming interstellar dust.
Dust that originates from comets, asteroids and leftover debris from the birth of the Solar System could deliver water and organic material to the Earth and other terrestrial planets, according to a recent Proceedings of the National Academy of Science paper.
The molecular clouds that float about the universe hold the ingredients for star formation, say researchers at University of California, San Diego.
Interstellar magnetic fields can be found throughout the Milky Way and other similar galaxies. They are thought to be a key regulator in star formation and the propagation of cosmic rays.
Astronomers using the Mopra Telescope in Coonabarabran, Australia have begun mapping the location where stars are born.
Heliophysics nuggets are a collection of early science results, new research techniques, and instrument updates that further our attempt to understand the sun and the dynamic space weather system that surrounds Earth.
