time, at 13.035 billion light-years. In other words, the universe was only 630 million years old when this burst occurred. 29 April 2009: Swift detected GRB 090429B, which was found by later analysis published in 2011 to be 13.14 billion light-years distant (approximately equivalent to 520 million years after the Big Bang), even farther than GRB 090423. 16 March 2010: Swift tied its record by again detecting and localizing four bursts in a single day. 13 April 2010: Swift detected its 500th GRB. 28 March 2011: Swift detected Swift J1644+57 which subsequent analysis showed to possibly be the signature of a star being disrupted by a black hole or the ignition of an active galactic nucleus. "This is truly different from any explosive event we have seen before", said Joshua Bloom of the University of California, Berkeley, the lead author of the study published in the June issue of Science. 16 and 17 September 2012: BAT triggered two times on a previously unknown hard X-ray source, named Sw J1745-26, a few degrees from the Galactic Center. The outburst, produced by a rare X-ray nova, announced the presence of a previously unknown stellar-mass black hole undergoing a dramatic transition from the low/hard to the high/soft state. 2013: Discovery of ultra-long class of gamma-ray bursts 24 April 2013: Swift detected an X-ray flare from the Galactic Center. This proved not to be related to Sgr A* but to a previously unsuspected magnetar. Later observations by the NuSTAR and the Chandra X-ray Observatory confirmed the detection. 27 April 2013: Swift detected the "shockingly bright" Gamma-ray burst GRB 130427A. Observed simultaneously by the Fermi Gamma-ray Space Telescope, it is one of the five closest GRBs detected and one of the brightest seen by either space telescope. 3 June 2013: Evidence for kilonova emission in short GRB 23 April 2014: Swift detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star. The initial blast from this record-setting series of explosions was as much as 10,000 times more powerful than the largest solar flare ever recorded. 3 May 2014: Detection of a UV Pulse from an iPTF discovered young Type Ia SN June–July 2015: The brown dwarf OGLE-2015-BLG-1319 was discovered using the gravitational microlensing detection method in a joint effort between Swift, Spitzer Space Telescope, and the ground-based Optical Gravitational Lensing Experiment, the first time two space telescopes
