WISE has its second asteroid discovery -- 2009 AG79 announced below. In this earlier infrared imagery, first discovery 2010 AB78 shows red against background stars. Queried about whether this was the first asteroidal object discovered from space, Gareth Williams at the IAU Minor Planet Center noted to A/CC that that milestone belongs to WISE's predecessor IRAS, which discovered Main Belter 3728 IRAS (1983 QF) and NEO 3200 Phaeton (1983 TB) a quarter century ago.
