This talk will describe near-Earth asteroids (NEAs) recently imaged by radar at Arecibo and Goldstone. In the past year, 25 NEAs have been detected by radar, 19 of them for the first time. Highlights include new images of 25143 Itokawa (1998 SF36), the target of Japan's Hayabusa mission, which is sched- uled to rendezvous with the asteroid this summer; 11066 Sigurd, a 3.5-km-long contact binary that is shaped like a peanut; 1998 ST27, a binary with a dis- tantly orbiting and rapidly spinning satellite; 3908 Nyx, topographically rugged, kilometer-sized object made of basalt; and 2004 MN4, which in April 2029 will make the closest approach to Earth (only 5.7 Earth radii) ever predicted.
