Spiral arms: Protoplanetary disk around a young star exhibits spiral structure

Thu, 29 Sep 2016 15:51:05 EDT

Astronomers have found a distinct structure involving spiral arms in the reservoir of gas and dust disk surrounding the young star Elias 2-27. While spiral features have been observed on the surfaces of protoplanetary disks, these new observations, from the ALMA observatory in Chile, are the first to reveal that such spirals occur at the disk midplane, the region where planet formation takes place. This is of importance for planet formation: structures such as these could either indicate the presence of a newly formed planet, or else create the necessary conditions for a planet to form. As such, these results are a crucial step towards a better understanding how planetary systems like our Solar system came into being.

Rosetta measures production of water at comet over two years

Thu, 29 Sep 2016 09:06:46 EDT

Over the past two years, Rosetta has kept a close eye on many properties of Comet 67P/Churyumov-Gerasimenko, tracking how these changed along the comet's orbit. A very crucial aspect concerns how much water vapour a comet releases into space, and how the water production rate varies at different distances from the Sun. For the first time, Rosetta enabled scientists to monitor this quantity and its evolution in situ over two years.

Experiment to investigate antibacterial properties of materials in space

Wed, 28 Sep 2016 07:32:13 EDT

Everybody knows a clean house is a healthy place to live, but what if you live on the International Space Station? Air and water are constantly recycled and waste can only be removed when a spacecraft departs for Earth every few months. For the six astronauts living in humanity's habitat in space, keeping the Station clean is an important part of their life to avoid bacteria and fungus. Every Saturday is cleaning day, when the whole crew wipe surfaces, vacuum and collect waste.

Precision measurements of exoplanet velocities

Wed, 28 Sep 2016 07:32:04 EDT

The search for exoplanets via the radial velocity technique has been underway for nearly thirty years, measuring the wobbles in a star's motion caused by the presence of orbiting bodies. The method has been very successful and has detected hundreds of exoplanets, but has been overtaken (at least in numbers of detections) by the transit method, which looks for dips in the star's light.

The ultraviolet diversity of supernovae

Wed, 28 Sep 2016 07:31:38 EDT

Supernovae, the explosive deaths of massive stars, are among the most momentous events in the cosmos because they disburse into space all of the chemical elements that were produced inside their progenitor stars, including the elements essential for making planets and life. One class of supernovae (Type Ia) provides yet another benefit: these objects are considered to be standard distance candles. They result when enough material from an orbiting companion star falls onto the progenitor star to trigger it to explode.
