Astronomers discover the ‘Mighty Mouse’ of stellar remnants

Published on 08/10/2014 

An international team of astronomers has found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar – a dense stellar remnant left over from a supernova explosion – ever recorded.

The most detailed exoplanet weather map ever

In this artist illustration the Jupiter sized planet WASP-43b orbits its parent star in what is one of the closest orbits ever measured for an exoplanet of its size — with a year lasting just 19 hours. The planet is tidally locked meaning it keeps one hemisphere facing the star, just as our Moon keeps one face toward Earth. The colour gradient on the planet represents the temperature across its atmosphere. This is based on data from a recent study that mapped the temperature of WASP-43b in more detail than has been done for any other exoplanet. Credit ESA, NASA.

This is an artist's concept of the silhouette of the extrasolar planet HAT-P-11b as it passes its parent star. The planet was observed as it crossed in front of its star in order to learn more about its atmosphere. Credit: NASA/JPL-Caltech
