Kepler’s final photos, and how you can see raw data

by Chris Burns, Slash Gear

The first and last images captured by the NASA-JPL space telescope Kepler are shown here side-by-side. This craft was launched back on March 7th, 2009, and its planned mission duration was 3.5 years. A full 9 years, 7 months, and 23 days later, it was still doing work. Now that span is over, and the final data’s come in.

Distant star is roundest object ever observed in nature

by PHYS.ORG

Stars are not perfect spheres. While they rotate, they become flat due to the centrifugal force. A team of researchers around Laurent Gizon from the Max Planck Institute for Solar System Research and the University of Göttingen has now succeeded in measuring the oblateness of a slowly rotating star with unprecedented precision. The researchers have determined stellar oblateness using asteroseismology – the study of the oscillations of stars. The technique is applied to a star 5000 light years away from Earth and revealed that the difference between the equatorial and polar radii of the star is only 3 kilometers – a number that is astonishing small compared to the star’s mean radius of 1.5 million kilometers; which means that the gas sphere is astonishingly round.
