Space travel is a bit safer than expected

Analysis of data from the MATROSHKA experiment, the first comprehensive measurements of long-term exposure of astronauts to cosmic radiation, has now been completed. This experiment, carried out on board and outside of the International Space Station, showed that the cosmos may be less hostile to space travelers than expected.

Ground-based detection of super-Earth transit paves way to remote sensing of exoplanets

Astronomers have measured the passing of a super-Earth in front of a bright, nearby Sun-like star using a ground-based telescope for the first time. The transit of the exoplanet 55 Cancri e is the shallowest detected from the ground yet. Since detecting a transit is the first step in analyzing a planet's atmosphere, this success bodes well for characterizing the many small planets that upcoming space missions are expected to discover in the next few years.

Exo-Earths and the search for life elsewhere: a brief history

The criteria for life on other planets is the focus of the 4th Australian Exoplanet Workshop, hosted by the University of Southern Queensland this week. The first in this series on exoplanets looks at the story so far in the search for life elsewhere in the universe.

NASA opens Cube Quest Challenge for largest-ever prize of $5 million

Competitors have a shot at a share of $5 million in prize money and an opportunity to participate in space exploration and technology development, to include a chance at flying their very own CubeSat to the moon and beyond as secondary payload on the first integrated flight of NASA's Orion spacecraft and Space Launch System rocket.

It's filamentary: How galaxies evolve in the cosmic web

How do galaxies like our Milky Way form, and just how do they evolve? Are galaxies affected by their surrounding environment? An international team of researchers proposes some answers. The researchers highlight the role of the 'cosmic web' on the evolution of galaxies that took place in the distant universe, a few billion years after the Big Bang.

Philae's triple play

A short but significant 'thud' was heard by the Cometary Acoustic Surface Sounding Experiment (CASSE) as Philae made its first touchdown on Comet 67P/Churyumov-Gerasimenko. The two-second recording from space is the very first of the contact between a man-made object with a comet upon landing.

Unravelling the mystery of gamma-ray bursts

A team of scientists hope to trace the origins of gamma-ray bursts with the aid of giant space 'microphones.' Researchers are trying to work out the possible sounds scientists might expect to hear when the ultra-sensitive LIGO and Virgo detectors are switched on in 2015.
