The physical properties of dense molecular clouds

Small, dense interstellar clouds of gas and dust, containing hundreds to thousands of solar-masses of material, are suspected of being the precursors to stars and stellar clusters. These so-called cores, with gas densities ...

Herschel sees budding stars and a giant, strange ring

The Herschel Space Observatory has uncovered a weird ring of dusty material while obtaining one of the sharpest scans to date of a huge cloud of gas and dust, called NGC 7538. The observations have revealed numerous clumps ...

Without a trace: Cells keep to one direction by erasing the path

(Phys.org) —Migrating cells, it seems, cover their tracks not for fear of being followed, but to keep moving forward. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have now shown ...

Fragments falling onto the Sun

(Phys.org) —Stars form as gravity coalesces the gas and dust in an interstellar cloud until the material develops clumps dense enough to become stars. Even after a star begins to burn its nuclear fuel it continues to grow ...

A ghostly 'ladder' in Saturn's F ring

Saturn's F ring is certainly a curious structure. Orbiting the giant planet 82,000 kilometers above its equatorial cloud tops, the F ring is a ropy, twisted belt of bright ice particles anywhere from 30-500 km wide. It can ...
