Water discovered on ‘Super-Earth’ raises first real hope of alien life

“Finding water in a potentially habitable world other than Earth is incredibly exciting'

“Finding water in a potentially habitable world other than Earth is incredibly exciting'

The extreme gravity would make walking impossible, and the sunlight is so fierce that developing cancer would be inevitable.

Although Hubble did not carry any instruments capable of spotting signs of life - such as methane - new telescopes will soon be launched which can hunt for biosignatures, and may finally answer the question of whether we are alone in the universe.

“This study marks a new era in exoplanet research, crucial to ultimately place the Earth, our only home, into the greater picture of the Cosmos. It brings us closer to answering the fundamental question: Is the Earth unique?”

In constant, K2-18b is wet and warm enough for life to have evolved. It is around twice the size of Earth and eight times the mass, orbiting a highly-active red dwarf star. Although its star is far cooler than our Sun, the planet is much closer to the star, so has a temperature range similar to Earth.

“We don’t really know what it’s like down there. It could be a waterworld, the surface could be quite wet, or we may have an entirely dry surface.

“Maybe this is not quite your vacation destination just yet, but life may have evolved differently there.”

The technique is called ‘transit spectroscopy’ and takes advantage of the fact that when a planet passes in front of its host star a small chunk of light is filtered through its atmosphere, leaving a footprint of the chemicals in that atmosphere.

“Over 4,000 exoplanets have been detected but we don’t know much about their composition and nature.

Dr Colin Vincent, Head of STFC’s Astronomy Division, said: “Finding other planets that might have the capability to support life is one of the holy grails of the astronomy community.

“This discovery by UK researchers is a giant leap forward in this endeavour, opening a new world of possibilities.

I'm intrugued by news from the planet hunters. It must be a childhood's sci-fi. Still, with all our science we've the knowledge to live sustainably on earth without the good sense to take our own advice. We'll always dream of distant worlds, but we're nowhere near ready for them. Highly unlikely to be actual life there

Why ‘hope’? It really isn’t. Yes but it'll take 110 light years to get there 😂😂😂😂😂 What advantages could we possibly glean from this information, interesting and fascinating though it is, when roughly a quarter of the world’s population don’t even have access to clean drinking water? Wouldn’t funds be better spent on projects that could benefit humankind? 🤷‍♀️

K2-18b: Water vapour discovery means giant 'super-Earth' could support lifeK2-18b: Scientists say discovery of water vapour on enormous Earth-like planet means it could support life Been there in holiday. Building new housing complex. I put ten thousand doombies on one as a deposit. It’s called the UK in 5 years. Awesomely Mind blowing 🤯

Scientists find WATER on a planet 110 light years from EarthScientists from University College London have discovered water vapour on the exoplanet K2-18b, which is twice the size of Earth and eight times the mass, and say it's the right temperature for life. Oh. 11 light years. 66 trillion miles. We are saved! Great news can we send all the remainers there Not again
