Telescope maps cosmic rays in Magellanic clouds

A radio telescope in outback Western Australia has been used to observe radiation from cosmic rays in two neighbouring galaxies, showing areas of star formation and echoes of past supernovae.

Balloon-borne telescope looks for cosmic gamma rays

Cosmic gamma rays can provide us with important insights into high-energy phenomena in our universe. The GRAINE (Gamma-Ray Astro-Imager with Nuclear Emulsion) collaboration aims to record high-energy cosmic gamma rays at ...

The origins of the cigar-shaped alien 'asteroid' 'Oumuamua

One of the highlights of 2017 was the discovery of the first object in our solar system that definitely came from somewhere else. At first we thought it was a comet, then an asteroid, and now the International Astronomical ...

Exchanges of identity in deep space

By reproducing the complexity of the cosmos through unprecedented simulations, a new study highlights the importance of the possible behaviour of very high-energy photons. In their journey through intergalactic magnetic fields, ...

Water on the moon?

Prior to the Apollo missions to the moon, scientists speculated that volatiles - including water - may have accumulated in permanently shaded regions at the poles. Then the Apollo era brought the return of lunar samples, ...

Parkes telescope takes on the Roger Federer of space

Using the moon and the GPS system, scientists have turned CSIRO's 64-m Parkes radio telescope in eastern Australia into a new tool for finding the highest-energy particles nature can hurl at us. The work is being presented ...

Turning the moon into a cosmic ray detector

Scientists from the University of Southampton are to turn the Moon into a giant particle detector to help understand the origin of Ultra-High-Energy (UHE) cosmic rays - the most energetic particles in the Universe.

Electric sparks may alter evolution of lunar soil

The moon appears to be a tranquil place, but modeling done by University of New Hampshire and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties ...

First H.E.S.S. II data reveal promising pulsar signal

Following the intensive commissioning phase of the largest Cherenkov telescope worldwide (H.E.S.S. CT5), the H.E.S.S. collaboration has announced the detection of cosmic gamma rays of 30 gigaelectronvolts (GeV). The High ...
