For the first time, scientists have observed an accretion disk – also referred to as a dusty hamburger – around a young star. An accretion disk is formed by diffused material in orbital motion around a central body that is typically a star. Gravity then causes material in the disk to spiral inward towards the central body. Here, they explain how this disk feeds the central young star during the onset of an extra-solar system.

An unmanned Chinese cargo ship has successfully docked with the orbiting space lab Tiangong-2. Tianzhou-1 is 10 metres in length and is said to carry 6.5 tonnes of supplies.This would mean it is able to carry double that of rival cargo ships, claims China. The craft raises China’s hopes for its first manned space station by 2022.After removing waste from the space lab it will burn up when re-entering Earth’s atmosphere.
