First near-Earth triple asteroid Press Release
These radar images of near-Earth asteroid 2001 SN263 were obtained on 2008 Feb 12 and 13. The resolution is 75m (250 feet) per pixel. Because the moons are rotating more slowly than the larger "primary", they appear narrower to the radar, which measures distance and speed. Arecibo transmitted 500 000 Watts toward the asteroid, but the echo power received with Arecibo's ultra-sensitive detectors and processed into these images totals less than a billionth of a billionth of a billionth of a watt. Arecibo is both the world's most powerful radar transmitter and the world's most sensitive radio receiver.

Neutron stars can be more massive, while black holes are more rare, Arecibo Observatory
Neutron stars and black holes aren't all they've been thought to be. In fact, neutron stars can be considerably more massive than previously believed, and it is more difficult to form black holes, according to new research developed by using the Arecibo Observatory in Arecibo, Puerto Rico. Paulo Freire, an astronomer from the observatory, will present his research at the American Astronomical Society national meeting in Austin on Jan. 11.

Arecibo telescope finds critical ingredients for the soup of life in a galaxy far, far
Astronomers from Arecibo Observatory radio telescope in Arecibo, Puerto Rico, have detected for the first time the molecules methanimine and hydrogen cyanide -- two ingredients that build life-forming amino acids -- in a galaxy some 250 million light years away.

Arecibo telescope's global users converge on nation's capital to plan threatened observatory's scientific future
WASHINGTON, D.C. -- More than 70 astronomers gathered on Capitol Hill this week, not to talk about the demise of a major national research facility, but to plan for its scientific future. With optimism, the group was planning the next 15 years of research for Puerto Rico's Arecibo Observatory, the home of the world's largest radio telescope.
