Kepler spacecraft, nearly out of fuel, suspends exoplanet search

9 July 2018 Astronomy Now

The Kepler spacecraft, nearly out of fuel, has suspended its search for exoplanets pending the downlink of stored data. Flight controllers hope to resume observations in August for as long as the dwindling propellant holds out.

With fuel running low, Kepler begins 18th observing campaign

27 May 2018 Astronomy Now

NASA’s Kepler Space Telescope began its 18th observing campaign on 12 May, an 82-day run focusing on star clusters, galaxies and a handful of solar system bodies as the spacecraft nears the end of its life. Among its targets is 99942 Apophis, an asteroid expected to pass close by Earth in 2029.

TESS planet hunter snaps test photo showing 200,000 stars

18 May 2018 Astronomy Now

NASA’s planet-hunting TESS satellite has completed a gravity assist flyby of the moon and sent back an initial test image from one of its four cameras showing about 200,000 stars. Science operations are expected to begin in mid June.

Kepler Space Telescope sheds light on fast-evolving supernovae

26 March 2018 Astronomy Now

NASA’s Kepler Space Telescope has captured a difficult-to-detect, fast-evolving supernova in the act of blowing up and rapidly fading away, allowing astronomers to rule out competing theories and come up with a plausible explanation.

Mysterious dimming of Tabby’s Star may be caused by dust

7 October 2017 Astronomy Now

One of the most mysterious stellar objects may be revealing some of its secrets at last. Called KIC 8462852, also known as Boyajian’s Star, or Tabby’s Star, the object has experienced unusual dips in brightness — NASA’s Kepler space telescope even observed dimming of up to 20 percent over a matter of days. In addition, the star has had much subtler but longer-term enigmatic dimming trends, with one continuing today.

Kepler finds Tabby’s Star is mysteriously dimming

8 August 2016 Keith Cooper

The so-called ‘most mysterious star in the galaxy’, also known as KIC 8462852, Tabby’s Star, the WTF (‘where’s the flux’) star and the ‘alien megastructure star’, has become even stranger according to new analysis of old observations from Kepler.

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.
