A submillimeter survey of protostars

The formation of stars involves the complex interactions of many phenomena, including gravitational collapse, magnetic fields, turbulence, stellar feedback, and cloud rotation. The balance between these effects varies significantly ...

Magnetic storms: A window to the past

Audrey Schillings recently defended her doctoral thesis about atmospheric loss from Earth and how it varies with solar wind conditions. Audrey was employed at the Swedish Institute of Space Physics and enrolled at Luleå ...

Astronomers catch wind rushing out of galaxy

Exploring the influence of galactic winds from a distant galaxy called Makani, UC San Diego's Alison Coil, Rhodes College's David Rupke and a group of collaborators from around the world made a novel discovery. Published ...

How black holes shape galaxies

Data from ESA's XMM-Newton X-ray observatory has revealed how supermassive black holes shape their host galaxies with powerful winds that sweep away interstellar matter.

Modeling floods that formed canyons on Earth and Mars

Geomorphologists who study Earth's surface features and the processes that formed them have long been interested in how floods, in particular catastrophic outbursts that occur when a glacial lake ice dam bursts, for example, ...

Lava, not water, formed canyons on Mars

The canyon-like scars which line Mars' crust are seen by many as evidence for liquid water. But a study now suggests that a different kind of fluid – one much less hospitable to life – may actually have carved these features.

Novel archaea found in geothermal microbial mats

(Phys.org)—Our oldest national park may hold answers to questions about the activities of microbial communities that, in turn, may help in developing bioenergy technologies or safely storing carbon dioxide. Detailed analyses ...
