Team radar from across several institutions were busy this month observing many targets of interest, including Comet 46P/Wirtanen, near-Earth asteroid 2003 SD220, and 7 other NEAs. The cross-institution teams used the NASA-funded Arecibo S-band planetary radar to study these objects in order to measure their astrometry, size, and characterize their surfaces. Read More

Second day observing near-Earth asteroid 2003 NW1 and we are being able to get radar images for the first time for this asteroid.
Third day observing comet 46P/Wirtanen. We'll be observing it at Arecibo every day until December 18th. It's closest approach to Earth at ~30 lunar distances will be on December 16th, and the data will only keep getting better each day.

Flea on Pluto? Arecibo Observatory Helps Provide Unprecedented View of Pulsar
Pulsar Astronomy
May 25, 2018:
Imagine being able to see a flea on the surface of Pluto. That’s a good way to describe what the Arecibo Observatory in Puerto Rico helped a group of Canadian researchers do. Read More
Pulsar Watchers Close In On Galaxy Merger History
Pulsar Astronomy
Feb 28, 2018
For the past twelve years, a group of astronomers have been watching the sky carefully, timing pulses of radio waves being emitted by rapidly spinning stars called pulsars, first discovered 50 years ago. These astronomers are interested in understanding pulsars, but their true goal is much more profound; the detection of a new kind of gravitational waves. With a new, more sophisticated analysis, they are much closer than ever before.
