China to launch dark matter satellite in mid-December
China is planning to launch its Dark Matter Particle Explorer Satellite, developed to study dark matter and high-energy particles in space, in mid-December after it left Shanghai today for the launch centre in the country’s northwest Gansu Province.
Developed by the Chinese Academy of Sciences (CAS), Dark Matter Particle Explorer (DAMPE) Satellite left Shanghai with its carrier Long March 2-D rocket and is expected to be launched at the Jiuquan Satellite Launch Centre.
An exoplanet with 5400 mph winds – which is seven times the speed of sound, or twenty times faster than anything ever recorded on Earth – has been discovered by scientists at the University of Warwick in England.
Study leader, Tom Louden, who works at the University of Warwick’s Astrophysics Group, said it is the first time a weather system has been directly mapped and measured on an exoplanet. An exoplanet is a planet outside our Solar System that orbits a star.
Warwick scientists measured the wind speeds on two sides of the exoplanet – called HD 189733b. They detected an incredibly powerful wind, travelling at more than 5400 mph, blowing from its day side to its night side.
Scientists capture image of asteroid being ripped by dead star forming Saturn-like disk
Scientists have, for the first time, captured an image of an asteroid as it was being torn apart by a dead star resulting in the formation of a glowing ring of debris similar to that of Saturn’s disk.
Christopher Manser, of the University of Warwick’s Astrophysics Group in the UK, said that they have long been aware about debris disks around white dwarfs but this is the first time that they were able to capture an image of one of these disks giving them unprecedented insight of these systems.
The image, which showed a spiral-like structure that the researchers believe is related to collisions of dust grains, revealed formations that cannot be detected in a single snapshot confirming that these systems are indeed disc-like.
