A hypervelocity white dwarf might be left over from a Type Ia supernova. Today’s paper studies the white dwarf in detail.
Astronomers study a gravitationally lensed emission line galaxy, with implications for the characteristics of early galaxy populations.
The new high-resolution, hydra-headed PEPSI spectrograph is now in operation. One of the first targets it investigated is an ancient, planet-hosting star.
After accidentally observing the wrong star this paper’s authors discovered a previously-unknown solar twin, a type of star which can help shed light on a number of questions in astronomy.
Magnetic fields always make things more compiclated. In today’s paper, the authors studied their effect on the atmosphere of white dwarf stars.

With the imminent launch of the James Webb Space Telescope next year, many scientists are asking what is next? Today’s bite, which focuses on a recent workshop on global coordination: future space-based Ultraviolet-Optical-Infrared Telescopes, hopefully represents the first steps towards the next big space telescope.
