Gone in a (cosmological) flash: a team of astronomers found 72 very bright, but quick events in a recent survey and are still struggling to explain their origin. Miika Pursiainen of the University of Southampton will present the new results on Tuesday 3 April at the European Week of Astronomy and Space Science.
AAVSO observers contribute key data to a rare microlensing exoplanet event with an Earth-like planet of 9.2 Â± 6.6 M_earth. This is the closest lensing system reported so far. Beautiful light curve in figure 1, showcasing synergy between AAVSO, ASAS-SN, FO, SL and CSAI.
