The mystery of methane on Mars may finally be solved as scientists Monday confirmed the presence of the life-indicating gas on the Red Planet as well as where it might have come from.
In the 15 years since a European...
Two giant radio galaxies have been discovered with South Africa's powerful MeerKAT telescope. These galaxies are thought to be amongst the largest single objects in the Universe. The discovery has been published today in Monthly Notices of the Royal Astronomical...
It lacks the drama of a shape-shifting alien creature, but another threat looms over the prospect of generations-long, interstellar space travel: Explorers arriving on Xanadu could face problems communicating with previous and subsequent arrivals, their spoken language having changed...
On Mars there are ‘Marsquakes’ which may produce hydrogen in the same way as on Earth.Credit: University of Aberdeen
Analysis of rocks in the Outer Hebrides has provided a tantalising clue that Mars may contain habitats which can potentially support...
An international research team led by Université de Montréal astrophysicist Lauren Weiss has discovered that exoplanets orbiting the same star tend to have similar sizes and a regular orbital spacing. This pattern, revealed by new W. M. Keck Observatory...

Lawrence Livermore National Laboratory (LLNL) scientists are part of a national planetary defense team that designed a conceptual spacecraft to deflect Earth-bound asteroids and evaluated whether it would be able to nudge a massive asteroid – which has a...
By reviving a technique capable of combining specialized gamma-ray telescopes to one giant virtual instrument, scientists have measured the diameters of individual stars hundreds of light-years away. The team used the four VERITAS telescopes (Very Energetic Radiation Imaging Telescope...
The rediscovery of a lost planet could pave the way for the detection of a world within the habitable "Goldilocks zone" in a distant solar system.
The planet, the size and mass of Saturn with an orbit of thirty-five days,...
