Latest Cosmic dust Stories
Eleven months ago, NASAâ€™s Stardust mission touched down in the Utah desert with the first solid comet samples ever retrieved from space. Since then, nearly 200 scientists from around the globe have studied the minuscule grains, looking for clues to our solar system.
A new image from NASA's Spitzer Space Telescope is helping astronomers understand how stardust is recycled in galaxies. The cosmic portrait shows the Large Magellanic Cloud, a nearby dwarf galaxy.
Each year nearly 40,000 tons of cosmic dust fall to Earth from outer space. Now, the first successful chronological study of extraterrestrial dust in Antarctic ice has shown that this amount has remained largely constant over the past 30,000 years
In 1987 a massive star exploded in a neighboring galaxy, an event called a supernova. It was the closest supernova to Earth since the invention of the telescope centuries ago. Major observatories and millions of people worldwide turned to watch the death of this star.
Astronomers using NASA's Spitzer Space Telescope think they may have found the source in type II supernovae, the violent explosions of the universe's most massive stars.
Particles from any icy comet that were collected and returned to Earth aboard a NASA science satellite show dozens of minerals that form only in extreme heat -- a finding that complicates theories about how the solar system formed, scientists said on Monday.
NASA's Stardust spacecraft was placed into hibernation mode yesterday. Stardust successfully returned to Earth samples of a comet via its sample return capsule on Jan. 15. The spacecraft has logged almost seven years of flight.
Scientists have made the first positive link between a breakup event in the main asteroid belt and a large quantity of interplanetary dust particles deposited on Earth.
Pristine comet samples returned this weekend by the Stardust spacecraft after a 2.9-billion-mile (4.7-billion-km) journey wildly exceeded scientists' expectations, project managers said on Thursday.
The newly returned Stardust space capsule arrived Tuesday at NASA's Johnson Space Center, where the space agency said scientists will unlock its internal canister and take a first peek at comet debris particles it was supposed to capture during a seven-year journey.
Nebula -- in astronomy, observed manifestation of a collection of highly rarefied gas and dust in interstellar space. Prior to the 1960s this term was also applied to bodies later discovered to be galaxies, e.g., the so-called Great Nebula in the constellation Andromeda. In 1864, William Huggins confirmed William Herschel's conclusion that nebulae are not swarms of stars by determining that the spectra of nebulae are made of bright lines characteristic of radiating gases. Diffuse...
