Asteroids and comets shower Mars with organics

Asteroids and comets appear to be a much more important supplier of organic molecules on Mars than expected. Until now, astronomers assumed that the organics on Mars mainly came from dust particles from space. Now, computer ...

Cosmic dust demystified

The solar system is a dusty environment, with trillions of cosmic dust particles left behind by comets and asteroids that orbit the sun. All this dust forms a relatively dense cloud through which the Earth travels, sweeping ...

Dust particles from afar

When in 1990 the solar probe Ulysses embarked on its 19-year-long exploration tour, the participating researchers turned their attention not only to our Sun, but also to significantly smaller research objects: interstellar ...

Study suggests space dust carries water and organic compounds

Researchers from the University of Hawaii-Manoa (UHM) School of Ocean and Earth Science and Technology (SOEST), Lawrence Livermore National Laboratory, Lawrence Berkeley National Laboratory, and University of California – ...

The mysterious case of asteroid Oljato's magnetic disturbance

(Phys.org)—Back in the 1980s, the arrival of asteroid 2201 Oljato inside the orbit of Venus heralded a flurry of magnetic activity. Now, results from ESA's Venus Express spacecraft suggest that Oljato has lost its magnetic ...

New instrument to capture stardust as part of NASA mission

Scientists and engineers at the CU Boulder will soon take part in an effort to collect a bit of stardust—the tiny bits of matter that flow through the Milky Way Galaxy and were once the initial building blocks of our solar ...
