Artist’s depiction of OSIRIS-REx in orbit around Bennu. Currently, the spacecraft is searching for other Trojan asteroids near Earth. Image Credit: NASA Asteroids are some of the most ancient objects in the Solar System, relics left over from the time when the planets first started forming and evolving. For this reason, scientists are […] 
Time-lapse view of the asteroid Euphrosyne as seen by NASA’s WISE spacecraft on May 17, 2010. WISE was later renamed to NEOWISE in 2013. Image Credit: NASA/JPL-Caltech Near-Earth asteroids, also known as Near Earth Objects (NEOs), are some of the best studied space rocks in the Solar System, primarily due to the fact […] This graphic depicts the orbit of comet C/2013 A1 Siding Spring as it swings around the Sun in 2014. On Oct. 19, 2014, the comet will have a very close pass at Mars. Its nucleus will miss Mars by about 82,000 miles (132,000 kilometers). Credit: NASA/JPL-Caltech Earth’s invasion fleet at Mars is about […] The notion of Planet X, a hypothetical massive planet orbiting the Sun beyond the known reaches of the Solar System, has held great appeal for the general public for many decades. The newest results from NASA’s WISE mission, however, indicate that no such planet exists. Image Credit: Warner Bros.
Deeply ingrained in […] Image Credit: NASA/JPL-Caltech The true identity of centaurs, the small celestial bodies orbiting the Sun between Jupiter and Neptune, is one of the enduring mysteries of astrophysics. Are they asteroids or comets? A new study of observations from NASA’s Wide-field Infrared Survey Explorer (WISE) finds most centaurs are comets. […] Image Credit: NASA WASHINGTON — NASA announced Tuesday a Grand Challenge focused on finding all asteroid threats to human populations and knowing what to do about them. […] An asteroid “family” is comprised of fragments of a parent body that was broken up during a collision. Image Credit: NASA / JPL / Caltech NASA’s Wide-field Infrared Survey Explorer (WISE) has found new members of asteroid families. This was accomplished by reviewing millions of images collected during the asteroid-hunting part of the […] Asteroid exploration has taken on renewed importance in recent years, with the close passage of 2012 DA14 in February 2013 drawing worldwide public attention. In addition to the proposed NEOCam telescope mission, NASA has announced plans for this Asteroid Retrieval Spacecraft, which may culminate in a mission as early as 2021 to bring […] An asteroid will make a very close approach to Earth on Feb. 15, and NASA is preparing for the encounter. Image Credit: Jeff Darling An asteroid is barreling toward Earth! But no worries … there’s no need to get Bruce Willis into a space shuttle and have him save us with a nuclear […] Artist’s impression of an asteroid approaching the Earth. Image Credit: Jeff Darling Be afraid – but not too afraid. It’s true that at some point, if we don’t take steps to prevent it, a big dumb object is going to smash into the Earth so hard that civilization as we know it will […] |
