Artificial intelligence, NASA data used to discover eighth planet circling distant star

17 December 2017 Astronomy Now

Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler-90, a Sun-like star 2,545 light-years from Earth. The planet was discovered in data from NASA’s Kepler Space Telescope.

Kepler space telescope discovers variability in the Seven Sisters

29 August 2017 Astronomy Now

The Seven Sisters, as they were known to the ancient Greeks, are now known to modern astronomers as the Pleiades star cluster – a set of stars which are visible to the naked eye and have been studied for thousands of years by cultures all over the world. A new algorithm to analyse data from NASA’s Kepler telescope has revealed insights about the behaviour of the stars.

Updated Kepler catalog contains 219 new exoplanet candidates

21 June 2017 Stephen Clark

Scientists have published a catalog of exoplanet discoveries made by NASA’s Kepler space telescope, identifying 219 previously-unknown planet candidates circling stars elsewhere in the galaxy, including 10 would-be worlds that appear to be about the same size of Earth with temperatures potentially hospitable for life.

Possible Venus twin discovered around dim star

11 April 2017 Astronomy Now

Astronomers using NASA’s Kepler space telescope have found a planet 219 light-years away that seems to be a close relative to Venus. This newly discovered world is only slightly larger than Earth and orbits a low-temperature star called Kepler-1649 that’s one-fifth the diameter of our Sun.

Kepler telescope recovered from spacecraft emergency

NASA’s Kepler planet-searching spacecraft is stable and out of emergency mode, officials said Monday, and the observatory is downlinking data to help engineers determine what caused it to suspend science operations last week.

Kepler space telescope in emergency mode

Mission controllers are trying to diagnose a problem that put NASA’s Kepler planet-hunting observatory in emergency mode nearly 75 million miles from Earth this week.

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.

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.

How an old law might bring new life to the search for habitable exoplanets

18 March 2015 Kerry Hebden

Researchers at the Australian National University and the Niels Bohr Institute in Copenhagen have calculated that billions of stars in the Milky Way will have between one and three planets in the habitable zone conducive to liquid water, by using a law proposed in 1766 that helped to discover Uranus.

NASA’s Kepler spacecraft proves it can still find planets

19 December 2014 Astronomy Now

When the primary mission of NASA’s Kepler spacecraft ended in May 2013 due to a failure of its stabilisation system, a team of scientists and engineers developed an ingenious strategy to control the spacecraft. The resulting second mission, K2, has a newfound planet — HIP 116454b
