Kepler's K2 mission confirms 104 Earth-like planets

An international team of astronomers has confirmed a treasure trove of new exoplanets spotted by NASA's Kepler spacecraft during its K2 mission. Kepler was launched in 2009 to search for Earth-like planets around Sun-like stars. Scientists describe the region where an exoplanet might be the right distance away from a star to …

Science non-fiction: Newly spotted alien world bathes in glow of three stars

A newly discovered planet is wedged in-between three stars and experiences triple sunrises and sunsets every day, according to new research published in Science. The planet, HD 131399Ab, is 340 light years away from Earth and can be found in Centaurus constellation – one of the largest constellations in the sky. "HD 131399Ab …

Planet 9 a captured alien, astroboffins suggest

Astroboffins have boldly suggested that the hypothetical trans-Neptunian Planet 9 is in fact an exoplanet captured by our young Sun from another star. That's according to astronomers from Sweden's Lund University and the Laboratoire d'Astrophysique de Bordeaux, who questioned the plausibility of a planet some ten times the …

Astroboffin discovers exoplanet by accident ... in 1917

A reexamination of astronomical records has shown that an astronomer unknowingly snapped an exoplanet during the First World War – well before such bodies were confirmed in the 1990s. In 1917 Dutch-American astronomer Adriaan van Maanen, working at the Mount Wilson Observatory (then part of Carnegie Observatories), took a …

Short weekend break: Skegness or exoplanet HD 189733b?

Our recent piece examining the extreme weather on exoplanet HD 189733b prompted some readers to suggest that conditions on the distant hot Jupiter are in fact more benign than those enjoyed by visitors to British seaside resort Skegness. Well, for those of you thinking of taking a short weekend break over Xmas, the better to …

Red dwarf superflares batter formerly 'habitable' exoplanet

Humanity may have to rethink colonisation plans for exoplanet Kepler-438b, since what was hailed earlier this year as a candidate to support life as we know it, has now been declared decidedly inhospitable. The planet - a probably rocky world with a diameter 12 per cent bigger than Earth - was identified back in January, …

Today's exoplanet weather: 1,000°C, glass rain, 8,700 km/h winds

Those readers who enjoy complaining about the weather might like to consider a short weekend break on 'hot Jupiter' exoplanet HD 189733b, where conditions will give them something to really moan about. Studies of HD 189733b – discovered in 2005 transiting the star HD 189733, which lies some 63 light years from Earth in the …

Ideal solar system for SECOND EARTH found – and it's just 186 light-years away

There are hundreds of known exoplanets - worlds in orbit around other stars than our own Sun. The trouble is, because of the means used to detect them, that they tend to be big and very close to their faraway suns - and thus, sadly, not potential Earthlike habitable worlds. But that may have changed today. Excited astronomers …

ATTENTION SETI scientists! It's TOO LATE: ALIENS will ATTACK in 2049

Today, top experts on aliens will debate one of the most pressing issues of modern times: to wit, should the human race send out signals with the aim of letting any possible extraterrestrial beings know we are here? But the brainboxes assembled in San Jose for the annual shindig of the American Association for the Advancement …

Boffins open 'space travel bureau': Come relax on exoplanet Kepler-16b, says NASA

Pics NASA appears to be transforming itself into an intergalactic travel agency after issuing a series of cheery posters of exoplanets. "Kepler-186f is the first Earth-size planet discovered in the potentially 'habitable zone' around another star, where liquid water could exist on the planet's surface," said NASA's blurb. Visit …

ALIEN EARTH: Red sun's habitable world spotted 470 light years away

The discovery of new planets likely to be able to support life along Earthly lines has been announced, with one of the most promising candidates for alien and/or human habitability located just 470 light-years away. The new exoplanets have been discovered by analysis of data from the Kepler space telescope, and bear the tags …

Astronomers spot hint of first EXOMOON, possibly

Thanks to the work of the Kepler space telescope and Earth-bound observations, we have now caught sight of nearly 2,000 exoplanets: planetary bodies orbiting distant stars. But now astronomers think they've caught the first sighting of an exomoon orbiting one of these distant planets. Planetary moons are relatively common in …

Alien planet is just like EARTH - except for ONE tiny detail

Four hundred light-years away in the constellation Cygnus there lies a G-type star very much like our own Sun. Orbiting it is a world scientists believe is very similar to Earth in both size and composition. This faraway planet, discovered by the Kepler space telescope and so dubbed Kepler-78b, is not a potential second home …
