A sanitizer in the galactic center region

An international group of researchers reports the first identification iso-propanol in interstellar space, a substance which is used as a sanitizer on Earth. Iso-propanol is the largest alcohol detected so far, demonstrating the increasing complexity of members of one of the most abundant classes of molecule that can be found in space.

Reading between the lines to model our galaxy's central black hole

Researchers were able to use the unique subtle flickering of the bright glow of orbiting gas to construct the most accurate model to date of our own galaxy's central black hole, providing insight into properties such as its structure and motion.

A novel crystal structure sheds light on the dynamics of extrasolar planets

Scientists evaluated how the atomic structure of magnesium germanate changes under extremely high pressures. They discovered that the mineral adopted the structure of a compound called thorium phosphide. This, they think, could be an important component of the deep interiors of large, rocky extrasolar planets.

A blueprint for life forms on Mars?

The extremely salty, very cold, and almost oxygen-free environment under the permafrost of Lost Hammer Spring in Canada's High Arctic is the one that most closely resembles certain areas on Mars. So, if you want to learn more about the kinds of life forms that could once have existed - or may still exist - on Mars, this is a good place to look.

Astronomers find evidence for most powerful pulsar in distant galaxy

Astronomers have discovered one of the youngest known neutron stars - possibly as young as only 14 years. The dense remnant of a supernova explosion was revealed when bright radio emission powered by the pulsar's powerful magnetic field emerged from behind a thick shell of debris from the explosion.
