- May 3, 2013 - NASA's Fermi, Swift See 'Shockingly Bright' Burst
- A record-setting blast of gamma rays from a dying star in a distant galaxy has wowed astronomers around the world. The eruption, which is classified as a gamma-ray burst, or GRB, and designated GRB 130427A, produced the highest-energy light ever detected from such an event.

- Three unusually long-lasting stellar explosions discovered by NASA's Swift satellite represent a previously unrecognized class of gamma-ray bursts (GRBs). Two international teams of astronomers studying these events conclude that they likely arose from the catastrophic death of supergiant stars hundreds of times larger than the sun.

- While performing an extensive X-ray survey of our galaxy's central regions, NASA's Swift satellite has uncovered the previously unknown remains of a shattered star. Designated G306.3–0.9 after the coordinates of its sky position, the new object ranks among the youngest-known supernova remnants in our Milky Way galaxy.

- Feb 25, 2013 - Swift/UVOT CALDB Update
- A new CALDB file describing the long term change in the sensitivity of the Swift/UVOT was released on January 18, 2013. The new file corrects the update on June 6, 2012, which erroneously produces no change in sensitivity instead of the actual gradual decline of 1.0% to 1.5% per year depending on filter. A more complete description of the file and its updates is available in this PDF. General information about the use of Swift CALDB files is available at the Swift Calibration page.
