ANIMATION “Sterile neutrinos” are theoretically predicted new particles that offer an intriguing possibility in the quest for understanding the dark matter in our universe. Unlike the known “active” neutrinos in the Standard Model (SM) of particle physics, these sterile neutrinos do not interact with normal matter as they move through space, making them very difficult to […]

Using data from several instruments onboard Rosetta, CASTRA’s team has modeled the properties of cometary dust in the environment of Comet 67P.

The US Defense Advanced Research Projects Agency (Darpa) has recently commissioned three private companies, Blue Origin, Lockheed Martin and General Atomics, to develop nuclear fission thermal rockets for use in lunar orbit. Such a development, if flown, could usher in a new era of spaceflight. That said, it is only one of […]

Saturn’s moon Enceladus, with its geysers of water (artist’s illustration), could be the target for a future European flagship mission. EUROPEAN SPACE AGENCY/SCIENCE OFFICE The biggest space missions gestate for the longest time. Today, the European Space Agency (ESA) revealed the three broad science themes it wants to pursue for […]

ANIMATION Graphene can be used for ultra-high density hard disk drives (HDD), with up to a tenfold jump compared to current technologies, researchers at the Cambridge Graphene Centre have shown. The study, published in Nature Communications, was carried out in collaboration with teams at the University of Exeter, India, Switzerland, […]
