Microscopic messengers from the depths of space

(Phys.org)—In 1990, an important space probe was launched, tasked with the ambitious mission of orbiting the sun and scanning our star at all latitudes. However, the much-publicized mission was not solar research but the ...

In the heart of Cygnus, NASA's Fermi reveals a cosmic-ray cocoon

(PhysOrg.com) -- The constellation Cygnus, now visible in the western sky as twilight deepens after sunset, hosts one of our galaxy's richest-known stellar construction zones. Astronomers viewing the region at visible wavelengths ...

Cosmic dust found in city rooftop gutters

(Phys.org)—A small team of researchers with Imperial College London, the Natural History Museum in London, Project Stardust in Norway and Université Libre de Bruxelles in Belgium, has found samples of cosmic dust in the ...

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 ...

Light scattering on dust holds clues to habitability

We are all made of dust. Dust particles can be found everywhere in space. Disks of dust and debris swirl around and condense to form stars, planets and smaller objects like comets, asteroids and dwarf planets. But what can ...

Even brown dwarfs may grow rocky planets

(Phys.org)—Astronomers using the Atacama Large Millimeter/submillimeter Array have for the first time found that the outer region of a dusty disc encircling a brown dwarf contains millimetre-sized solid grains like those ...

VLT takes a close look at NGC 6357

(Phys.org) -- ESO's Very Large Telescope (VLT) has taken the most detailed image so far of a spectacular part of the stellar nursery called NGC 6357. The view shows many hot young stars, glowing clouds of gas and weird dust ...
