Astronomers have discovered the first known asteroid with a ring. Asteroid 10199 Chariklo, an asteroid orbiting between Saturn and Uranus, is the first object known to have a ring that isn’t a gas giant. The two concentric rings are dense, thin, and bright according to astronomers. The outer ring is 3 km wide and the inner ring is 6.5 km wide with a gap of 9 km between the rings. Chariklo is 250 km wide.
On February 26, NASA announced the discovery of an addition 715 planets found by the Kepler space observatory. These 715 planets are in orbit around 305 distinct stars and NASA has said that four of the planets orbit in the Golidlocks zone, where life is possible. THe new planets join nearly 1,000 previously discovered extrasolar planets and are from data collected by Kepler between its launch in 2009 and 2011.
China’s Jade Rabbit lunar rover, also known as Yutu, suffered a potentially mission ending breakdown which prevents it from hibernating during the 14-day long lunar night. If it does not enter hibernation mode, the rover may cease to function. The Chinese space agency issued a light-hearted news release, written as if by the rover, to announce the issue.
The ESA’s Herschel Space Observatory has detected signs of water vapor being ejected from Ceres, the largest asteroid. The two plumes, which are in different regions of the asteroid, are probably sublimation of ice into clouds of vapor or ice volcanoes. Scientists have believed that Ceres might have water for more than thirty year, but this was the first proof.
China landed the Chang’e 3 probe on the Moon at Sinus Iridium on December 14 at 8:11 a.m. EST. The probe carries the lunar rover Yutu and makes China the third country, along with the US and the Soviet Union, the successfully send probes to the Moon. This is the first soft landing on the moon since the Soviet Union’s Luna 24 landed in 1976. China launched Chang’e 3 on December 2 and it has been in Lunar orbit since December 7.
In 1953, Fritz Leiber published The Wanderer, about a planet that moved through interstellar space, without a sun to orbit. Scientists have now announced the discovery of PSO J318.5-22, a gas giant located 80 light years from Earth that does not orbit a primary. With only six times the mass of Jupiter, the planet is believed to be 12 million years old, relatively young for a planet. The lack of a primary makes it easier for scientists to study the planet.
Former JPL Director Bruce C. Murray (b.1931) died on August 29. Murray served as director of the Jet Propulsion Laboratory from 1976 through 1982, a period that saw the launch of the Voyager probes. While serving as director, Murray co-founded, along with Carl Sagan and Louis Friedman, the Planetary Society, in 1980, to support research related to astronomy, planetary science, exploration, public outreach, and political advocacy.
The Russian Olympic Committee has announced that all gold medals awarded on February 15, 2014 at the Winter Olympics in Sochi, Russia will contain pieces of the meteorite that exploded over the Russian city of Chelyabinsk on February 15, 2013. Seven sets of gold medals will be awarded on the anniversary of the meteor strike, including Men’s 1,500 meter Speedskating, Women’s 1,000m and Men’s 1,500m Short Track, Women’s Cross-Country Skiing Relay, Men’s K-125 Ski Jump, Women’s Super Giant Slalom, and Men’s Skeleton.
Astronomer Mark Showalter has discovered a fourteenth moon of Neptune while examining old imagery of the planet taken by the Hubble Space Telescope. The new moon, currently called S/2004 N 1, is believed to be twelve miles in diameter and orbiting Neptune at a distance of 65,400 miles, between the orbits of the moons Larissa and Proteus. This is the sixth moon Showalter has been involved in discovering, including the two recently named Plutonian moons, Styx and Kerberos.
Amazon founder Jeff Bezos has announced that a privately funded effort has located and recovered two of Apollo 11’s first stage F1 engines located on the ocean floor about 350 miles from Cape Canaveral in 3 miles of water. The engines were part of the first stage booster that lifted Apollo 11 on the flight that resulted in the first manned landing on the moon.
