NASA’s OSIRIS-REx spacecraft continues its so far flawless journey to asteroid Bennu, after successfully completing its first Trajectory Correction Maneuver (TCM-1) on Oct. 7. According to the mission’s Deputy Principal Investigator, the probe is currently in good health and all of its instruments are working properly.

Now you might wonder, how exactly playing bingo could help astronomers uncover the mysteries of elusive dark matter? Well, instead of playing this game literally, an international team of researchers, has proposed a project named BINGO (Baryon acoustic oscillations In Neutral Gas Observations) to build a special purpose radio telescope that could provide crucial insight on the real nature of dark energy. So, does this mean we could be hearing astronomers shouting out loud: “Bingo!” or rather “BINGO!”, when solving another astronomical conundrum?
Nearly a week after its launch, Orbital ATK’s Cygnus spacecraft berthed with the International Space Station (ISS) on Sunday, October 23, 2016, at 10:53 a.m. EDT (14:53 GMT), 250 miles (402 kilometers) above the Indian Ocean. The capsule is now attached to the nadir (Earth-facing) port on the station’s Unity module.
Astronomers have discovered possible evidence for water on the surface of the largest metallic asteroid in the solar system. Named 16 Psyche, the bolide is one of the most massive in the Asteroid Belt, measuring 186 miles across and consisting of almost pure nickel-iron metal. It is thought to be the remnant core of a planetary embryo that was mostly destroyed by impacts billions of years ago.

NASA’s Mars Reconnaissance Orbiter (MRO) has confirmed the worst fears of the ExoMars team by identifying new markings on the surface of the Red Planet that are believed to be related to Europe’s Schiaparelli test lander, which arrived at Mars on Oct. 19. Schiaparelli’s signal cut off about 50 seconds before its planned touchdown.
University of Idaho researchers have spotted patterns in Uranus’ rings that hint at the presence of two tiny, previously undiscovered moonlets orbiting the solar system’s seventh planet. Rob Chancia, a doctoral student in the UI College of Science Department of Physics, spotted the patterns while examining decades-old data on Uranus’ rings obtained by the Voyager 2 spacecraft in 1986. He noticed the amount of ring material on the edge of the alpha ring, one of the brightest of Uranus’ multiple rings, varied periodically. A similar, even more promising pattern occurred in the same part of the neighboring beta ring.
A group of citizen scientists and professional astronomers, including Carnegie’s Jonathan Gagné, joined forces to discover an unusual hunting ground for exoplanets. They found a star surrounded by the oldest known circumstellar disk—a primordial ring of gas and dust that orbits around a young star and from which planets can form as the material collides and aggregates.
