... of over 4100 metres above sea level, these detectors are sensitive to fleeting flashes of light known as Cherenkov radiation, that have energies from 100 gigaelectronvolts (GeV) to 100 teraelectronvolts (TeV). The observatory has recently been...
...Red Planet’s surface helping it to sustain liquid water all year-round while protecting it from harmful ultraviolet (UV) radiation. Sound fantastical? Not necessarily, as a new study by scientists in the US and UK have found that such a situation has...
... is no exception. Owing to its intense temperature, the star emits large amounts of heat, and ultraviolet and X-ray radiation – an environment that should make it exceedingly difficult to form a large planet, but that is what Janson and colleagues...
