LJMU at the forefront of the search for other-Earths



Liverpool Telescope helps to track down seven new planets

The Liverpool Telescope has helped to find seven earth-sized worlds.  

The discovery of a system of seven Earth-sized planets just 40 light-years away was made possible by a team of astronomers from across the world. 

The research, published in Nature, was led by the STAR Institute at the University of Liège. It used orbiting NASA Spitzer Space Telescope in addition to ground-based facilities including the Liverpool Telescope, owned and operated by the Liverpool John Moores University Astrophysics Research Institute (ARI).

The Liverpool Telescope helped to detect the planets as they passed in front of their parent star, the ultracool dwarf star known as TRAPPIST-1. At least three of the planets could harbour oceans of water on their surfaces, increasing the possibility that the star system may play host to life. This system has both the largest number of Earth-sized planets yet found, making it a key object for future study.

Dr Chris Copperwheat, a co-author on the paper, and a member of the ARI, commented on the role of the Liverpool Telescope:

“LJMU is at the forefront of the search for other-Earths and the search for other life in the Universe. The Astrophysics Research Institute was delighted to be part of this ground-breaking research using the Liverpool Telescope. The discovery of multiple rocky planets with surface temperatures which allow for liquid water make this amazing system an exciting future target in the search for life.

“As a robotic telescope and the largest in the world, the Liverpool Telescope is very sensitive to the small, less than 1 per cent dips in brightness through which the planets are discovered. It's all automated, it’s flexible and fast, and so is ideal for this sort of time critical work. Supporting the orbiting NASA Spitzer Space Telescope observing schedule, often at very short notice, is a simple task for astronomers who can use our telescope from anywhere in the world.”

The ARI is currently in the process of designing the New Robotic Telescope, a facility which will take the Liverpool Telescope’s crown as the world’s largest robotic telescope dedicated to science, and which will be a powerful tool in the search for other-Earths, liquid water and life over the coming decades.

Video description

The Liverpool Telescope in action (note: general observations taken by the Telescope and not footage of the research announced in this release)

The Liverpool Telescope is one of the largest and most advanced fully robotic telescopes in the world, especially dedicated to the study of variable and transient astronomical phenomena. In this time-lapse video we follow this giant Meccano while observing the Universe at the Roque de los Muchachos Observatory, in the summits of La Palma (Canary Islands, Spain), one of the best places on Earth for astronomical observation.

The Liverpool Telescope, owned and operated by the Liverpool John Moores University (LJMU) Astrophysics Research Institute, is mainly used for professional astronomical research, although part of its observational time is devoted to educational projects in Spain, the Educational Project with Robotic Telescopes (PETeR) of the IAC, and in the UK, the National Schools’ Observatory (NSO) of the LJMU.

This is a production of the IAC Communication and Scientific Culture Unit and Daniel López (elcielodecanarias.com), with the collaboration of the LJMU Astrophysical Research Institute.
