This event was first identified by the Wide-field X-ray Telescope on June 28, 2026. The source does not fit any known class of cosmic explosion.What's confirmed:The Wide-field X-ray Telescope on the Einstein Probe mission detected X-ray transient EP260628c starting at 2026-06-28 16:22:49 UTC.EP260628c is located at R.A. = 339.500 deg and Dec = 53.226 deg with a radius uncertainty of 2.7 arcmin.The absorption-corrected 0.5-4 keV flux for EP260628c is 1.3 (+7.6/-0.6) x 10^-10 erg cm^-2 s^-1.A previously detected source c https://www.live-feeds.com/feed/einstein-probe-detects-mysterious-x-ray-transient-that-doesn-t-fit-any-known-classhttps://www.live-feeds.com/feed/einstein-probe-detects-mysterious-x-ray-transient-that-doesn-t-fit-any-known-class#u17442Mon, 29 Jun 2026 14:41:43 +0000The Einstein Probe has identified unusual X-ray transients that do not fit known astronomical classes. One event, EP260623a, was located 6.8 billion light-years away in Pegasus. Astronomers are investigating if these flashes result from intermediate-mass black holes destroying white dwarf stars.What's confirmed:The Einstein Probe detected an X-ray transient that does not fit any known class.X-ray transient EP260623a was detected on June 23, 2026, at a distance of 6.8 billion light-years in Pegasus.The Einstein Probe is a Chinese space telescope.Still unconfirmed:The event may have been an inte
