Detecting water in space and why it matters

Miguel Pereira Santaella, Research Associate at the Oxford University Department of Physics, discusses his newly published work observing never before seen water transitions in space. He breaks down how the discovery will ...

ALMA spots possible formation site of icy giant planet

Astronomers found signs of a growing planet around TW Hydra, a nearby young star, using the Atacama Large Millimeter/submillimeter Array (ALMA). Based on the distance from the central star and the distribution of tiny dust ...

Rosetta captures comet outburst

In unprecedented observations made earlier this year, Rosetta unexpectedly captured a dramatic comet outburst that may have been triggered by a landslide.

Behind the scenes of protostellar disk formation

For a long time the formation of protostellar disks – a prerequisite to the formation of planetary system around stars – has defied theoretical astrophysicists: In a dense, collapsing cloud of gas and dust, the magnetic ...

Dust counter got few 'hits' on Pluto flyby

A student-built University of Colorado Boulder instrument riding on NASA's New Horizons spacecraft found only a handful of dust grains, the building blocks of planets, when it whipped by Pluto at 31,000 miles per hour last ...

The frigid Flying Saucer

The international team, led by Stephane Guilloteau at the Laboratoire d'Astrophysique de Bordeaux, France, measured the temperature of large dust grains around the young star 2MASS J16281370-2431391 in the spectacular Rho ...

Planetary influences on young stellar disks

A newborn star typically has a disk of gas and dust from which planets develop as the dust grains collide, stick together and grow. Stars older than about five million years lack evidence for these disks, however, suggesting ...

Mercury gets a meteoroid shower from comet Encke

The planet Mercury is being pelted regularly by bits of dust from an ancient comet, a new study has concluded. This has a discernible effect in the planet's tenuous atmosphere and may lead to a new paradigm on how these airless ...
