Earth-size habitable-zone planet found in archived Kepler data

19 April 2020 Astronomy Now

Researchers taking a second look at archived Kepler data find a mislabled Earth-size exoplanet in a red dwarf’s habitable zone.

TESS finds its first Earth-size planet in host sun’s habitable zone

7 January 2020 Astronomy Now

NASA exoplanet-hunting TESS satellite has found its first habitable-zone Earth-size planet and another orbiting an eclipsing binary system.

News

New study suggests tighter restrictions on exoplanet habitability

11 June 2019 Astronomy Now

New research indicates a star’s habitable zone may be narrower than previously believed, making it tougher for ET to evolve and thrive.

News

Low-mass star simulations favour water-rich, Earth-sized planets

24 October 2016 Astronomy Now

Astrophysicists at the University of Bern conducting computer simulations of the formation of planets orbiting in the habitable zone of low-mass stars, such as the red dwarf Proxima Centauri, show that these planets are most likely to be roughly the size of the Earth and to contain large amounts of water.

Potentially-habitable planet discovered around nearest star Proxima Centauri

24 August 2016 Keith Cooper

A planet with at least 1.3 times the mass of Earth has been discovered orbiting within the habitable zone of the nearest star to our Sun, Proxima Centauri, which is just 4.2 light years away.

A new Goldilocks for habitable planets

22 August 2016 Astronomy Now

The search for habitable, alien worlds beyond our Solar System needs to make room for a second “Goldilocks,” according to a Yale University researcher. The new study suggests that simply being in the habitable zone isn’t sufficient to support life.

NASA’s Kepler mission announces largest collection of exoplanets ever discovered

10 May 2016 Astronomy Now

NASA’s Kepler mission has verified 1,284 new planets — the single largest finding of planets to date. Of the nearly 5,000 total planet candidates found to date, more than 3,200 now have been verified, and 2,325 of these were discovered by the space telescope. Launched in March 2009, Kepler is the first NASA mission to find potentially habitable Earth-size planets.

No. 4 A planet like Earth?

2 January 2016 Keith Cooper

There was great media excitement in July when it was announced that the Kepler Space Telescope had discovered the most Earth-like planet yet, but appearances can be deceiving.

News

Magnetic fields likely protect Earth-like planets around small stars

30 September 2015 Astronomy Now

Earth-like planets orbiting close to small stars probably have magnetic fields that protect them from stellar radiation and help maintain surface conditions that could be conducive to life, according to research from astronomers at the University of Washington just published in the journal Astrobiology.

News

New Kepler planet could be Earth’s closest cousin yet

23 July 2015 Keith Cooper

A super-earth discovered by NASA’s Kepler Space Telescope and orbiting an older version of our Sun, is tantalising astronomers as potentially being the closest thing to a world like Earth.
