TL;DR: The Northern Sky Variability Survey (NSVS) as mentioned in this paper is the most extensive record of stellar variability across the bright sky available today, containing light curves for approximately 14 million objects.

TL;DR: In this article, ground-based and Swift photometric and spectroscopic observations of the candidate tidal disruption event (TDE) ASASSN-14li, found at the center of PGC043234 (d'90 Mpc) by the All-Sky Automated Survey for SuperNovae (ASAS-SN).

TL;DR: Astronomers report observations with the Swift Space Telescope of strong but declining ultraviolet emission from a type Ia supernova within four days of its explosion, consistent with theoretical expectations of collision between material ejected by the supernova and a companion star, and therefore provides evidence that some type IA supernovae arise from the single degenerate channel.
