TL;DR: Radar ranging from Arecibo, Puerto Rico, to the 0.5-kilometer near-Earth asteroid 6489 Golevka unambiguously reveals a small nongravitational acceleration caused by the anisotropic thermal emission of absorbed sunlight, which is a function of the asteroid's mass and surface thermal characteristics.
Journal ArticleDOI
Venus: Volcanism and Rift Formation in Beta Regio
TL;DR: A new high-resolution radar image of Beta Regio, a Venus highland area, confirms the presence of a major tectonic rift system and associated volcanic activity.
Journal ArticleDOI
Venus - Identification of banded terrain in the mountains of Ishtar Terra
TL;DR: In this article, high resolution images obtained with the Arecibo radar system at a wavelength of 12.6 centimeters reveal numerous parallel 10- to 20-kilometer-wide bands of high radar backscatter situated on and oriented parallel to the major mountain ranges of the Ishtar Terra region of Venus.
Journal ArticleDOI
Styles of volcanism on Venus - New Arecibo high resolution radar data
TL;DR: Radar data of Venus provides strong evidence that the mountains in Beta and Eisila Regiones and plains in and adjacent to Guinevere Planitia are of volcanic origin and suggests that heat loss by abundant and widely distributed plains volcanism may be more significant than previously recognized.

TL;DR: In this paper, the time delay and Doppler frequency measurements for asteroid-radar echoes obtained at Arecibo and Goldstone during 1980-1990 were reported for 23 near-earth asteroids and three mainbelt asteroids.
