Scientists find a hot 'super-Earth' and 60 more planets, boosting chances of discovering life

The findings suggest that there are many more planets out there waiting to be found – which might support alien life

Astronomers have found 60 new planets near our own – boosting the chances of finding one that could support life.

A team of international scientists found a further 54 potential planets, meaning that in all the researchers might have discovered a full 114 planets.

And at least some of those might be like Earth, and able to support life, the researchers have said.

One of the exoplanets was a hot "super-Earth" that has a rocky surface and is found in the fourth nearest star system to our own. That planet, known as Gliese 411-b, could suggest that all the stars near our own sun have planets orbiting them – and as such that those too might be like Earth and have the conditions for supporting alien life.

The results are based on almost 61,000 individual observations of 1,600 stars taken over a 20-year period by US astronomers using the Keck-I telescope in Hawaii.

The observations were part of the Lick-Carnegie Exoplanet Survey, which was started in 1996 by astronomers Steve Vogt and Geoffrey Marcy from the University of California and Paul Butler, from the Carnegie Institute of Science, in Washington.

Dr Tuomi, who was the only European-based researcher working on the project and led analysis of the data, said: "It is fascinating to think that when we look at the nearest stars, all of them appear to have planets orbiting them.

"This is something astronomers were not convinced about, even as little as five years ago.

"These new planets also help us better understand the formation processes of planetary systems and provide interesting targets for future efforts to image the planets directly," the University of Hertfordshire scientist said.

Dr Butler said: "This paper and data release is one of my crowning achievements as an astronomer. It represents a good chunk of my life's work."

The group's paper has been accepted for publication in The Astrophysical Journal.
