Technique pulls interstellar magnetic fields within easy reach

A new, more accessible and much cheaper approach to surveying the topology and strength of interstellar magnetic fields—which weave through space in our galaxy and beyond, representing one of the most potent forces in nature—has ...

Galaxies as 'cosmic cauldrons'

Star formation within interstellar clouds of gas and dust, so-called molecular clouds, proceeds very rapidly yet highly inefficiently. Most of the gas is dispersed by stellar radiation, revealing galaxies to be highly dynamic ...

Halfway mark for NOEMA construction

The completion of NOEMA phase 1, the first phase of the NOEMA project will be officially celebrated this Wednesday, September 19th. IRAM and its partner institutes have completed the first, decisive step towards one of the ...

Image: Star-forming filaments

The plane of the Milky Way is rich in star-forming regions, such as the one pictured in this stunning scene by ESA's Herschel space observatory. To the far-infrared eye of Herschel, this region reveals an intricate network ...

How multiple star systems evolve

Sirius is not a single star at all, but a binary system of two stars. Polaris, the north star, is actually a system of three stars. And Castor, in the constellation of Gemini, actually consists of a whopping six stars. Current ...

First look at gravitational dance that drives stellar formation

Swirling motions in clouds of cold, dense gas have given, for the first time, an active insight into how gravity creates the compact cores from which stars form in the interstellar medium. The results will be presented today, ...

Understanding star formation in the nucleus of galaxy IC 342

An international team of researchers used NASA's Stratospheric Observatory for Infrared Astronomy, SOFIA, to make maps of the ring of molecular clouds that encircles the nucleus of galaxy IC 342. The maps determined the proportion ...

Fermi finds possible dark matter ties in Andromeda galaxy

NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to ...
