Dust involved in sulfate production in clouds
Water on Moon and Earth came from same primitive meteorites, analysis shows
The water found on the moon, like that on Earth, came from small meteorites called carbonaceous chondrites in the first 100 million years or so after the solar system formed, researchers from Brown and Case ...
Cirrus clouds form around mineral dust and metallic particles, study finds
At any given time, cirrus clouds—the thin wisps of vapor that trail across the sky—cover nearly one-third of the globe. These clouds coalesce in the upper layers of the troposphere, often more than 10 ...
Melvin Calvin's moon dust rediscovered at Berkeley Lab
(Phys.org) —When Apollo 11 returned from its historic flight in 1969, the moon rocks and lunar soil collected by Neil Armstrong and Buzz Aldrin eventually found their way to some 150 laboratories worldwide. ...
Wind and cold carry dust to new heights
(Phys.org) —Scientists at China's Lanzhou University and Pacific Northwest National Laboratory found that dust lifted from the Taklimakan Desert during a dust storm had a significant effect on the regional ...
Herschel bows out with study that shows early galaxies 'cooler' than predicted
(Phys.org) —Physicists analysing observations from the Herschel Space Observatory have shown that galaxies in the early Universe were cooler than those we see around us today.
Herschel telescope bows out after successful mission
Europe's deep-space Herschel telescope has given up the ghost—running out of coolant after a successful mission to observe the birth of stars and galaxies, the European Space Agency said Monday.
Comet Lemmon, Now in STEREO
An icy interloper was in the sights of a NASA spacecraft this past weekend. Comet 2012 F6 Lemmon passed through the field of view of NASA's HI2A camera as seen from its solar observing STEREO Ahead spacecraft. ...
Microscopic dust particles found in underground railways may pose health risk
New research from the University of Southampton has found that working or travelling on an underground railway for a sustained period of time could have health implications.
Hubble brings faraway comet into view
(Phys.org) —The NASA Hubble Space Telescope has given astronomers their clearest view yet of Comet ISON, a newly-discovered sun grazer comet that may light up the sky later this year, or come so close to ...
Grains of sand from ancient supernova found in meteorites
(Phys.org) —It's a bit like learning the secrets of the family that lived in your house in the 1800s by examining dust particles they left behind in cracks in the floorboards.
ALMA pinpoints early galaxies at record speed
(Phys.org) —A team of astronomers has used the new ALMA (Atacama Large Millimeter/submillimeter Array) telescope to pinpoint the locations of over 100 of the most fertile star-forming galaxies in the early ...
Putting the stars within reach
When you look at the night sky, you see stars, a few planets, and perhaps even the Milky Way's spangled belt stretched across the middle.
Study of lunar dust may lead to better flood forecasts on Earth
Forecasters may one day be able to provide better flood warnings, thanks to the Apollo astronauts who landed on the moon more than four decades ago.
