A peanut-shaped asteroid almost a mile long known as 2014 JO25 passes within 5 lunar distances of Earth on 19 April — the closest any known space rock of this size has approached our planet since September 2004. We show you how to find this fast-moving potentially hazardous asteroid in small telescopes during the UK night of 19-20 April.
Technology developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) will sit at the heart of one of the world’s biggest ever science projects, the Five hundred metre Aperture Spherical Telescope (FAST), following an agreement with the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC).
Astronomers using an orbiting radio telescope in conjunction with four ground-based radio telescopes have achieved the highest resolution, or ability to discern fine detail, of any astronomical observation ever made. The researchers were surprised when their Earth-space system revealed a core temperature hotter than 10 trillion degrees for quasar 3C 273.
