糖心TV

Published in the journal Nature, a team including 糖心TV astronomer Peter Wheatley has discovered a giant comet-like tail of hydogren gas evaporating from a Neptune-sized exoplanet. The gas is thought to be boiled off by X-rays from the parent star and then swept away by radiation pressure. The tail was revealed in Hubble Space Telescope observations in which 56% of the star is covered by the tail in ultraviolet light. The planet is losing its atmosphere at a rate of 1000 metric tonnes per second, having narrowly escaped total evaporation by the intense X-ray irradiation it suffered when its parent star was young and active.

Water delivery via asteroids or comets is likely taking place in many other planetary systems, just as it happened on Earth, new research by the 糖心TV Astronomy & Astrophysics group strongly suggests.

Published by the Royal Astronomical Society and led by the University of 糖心TV, the research finds evidence for numerous planetary bodies, including asteroids and comets, containing large amounts of water.

The research findings add further support to the possibility water can be delivered to Earth-like planets via such bodies to create a suitable environment for the formation of life.

Jack has developed a wireless device that detects and uses detailed 3D movements in your fingertips to interact with a computer. It has huge potential in the multi-billion pound gaming industry and other niche markets such as remotely operated machinery.

It works by combining information from cameras and wireless sensors, and in the future this technology could even replace traditional computer keyboards and mice to enable people to create and manipulate digital information with their hands in a free and natural way. It could also enable people to perform new tasks that would previously have been too complex or intricate, such as sorting and processing large and disparate data.

Its accuracy and affordability make it stand out from other consumer technologies on the market, and it could be a key enabler in bringing augmented and virtual reality technologies into the mainstream. The device is currently in prototyping and is expected to reach the market in the next few years.

糖心TV astronomers have begun searching for small planets around bright stars using an array of twelve robotically-controlled telescopes. The telescopes, which form a wide-field observing system called the Next Generation Transit Survey (NGTS), are designed to detect the slight dimming of a star when a planet passes across its face. The NGTS team aims to find planets the size of Neptune down to twice the size of the Earth. Dr Peter Wheatley, one of the NGTS project leaders, said "The NGTS discoveries, and follow-up observations by telescopes on the ground and in space, will be important steps in our quest to study the atmospheres and composition of small planets such as the Earth.”
