Decisions on the future of a joint robotic mission between NASA and the European Space Agency to demonstrate the ability to deflect an asteroid on a collision course with Earth have been put off until later this year after European governments declined to fully fund their part of the project in December.
NASA’s Dawn spacecraft has continued its survey of the dwarf planet Ceres this year, discovering rock-bound ice hidden just beneath the airless world’s rugged surface and a handful of icy outcrops inside craters in the northern hemisphere, raising hopes that Ceres could have once held a buried habitable ocean of liquid water.
Las Cumbres Observatory have partnered with Asteroid Day 2016 and Universe Awareness to create a website which allows you to use a global network of robotic telescopes to take pictures of two asteroids — 2002 KL6 and 2010 NY65 — currently passing close to Earth. On the website you can join the international campaign to study and raise awareness about asteroids.
According to a new international study, most (>80 percent) of the water inside the Moon was delivered by asteroids similar to carbonaceous chondritic meteorites during the early lunar evolution, approximately 4.5—4.3 billion years ago. A similar delivery of water to the Earth would have been occurring within this same interval of time.
By combining data from two space observatories, astronomers have revealed something surprising: a 955-mile-wide dwarf planet named 2007 OR10 is significantly larger than previously thought. Although its 547-year-long elliptical orbit brings it nearly as close to the Sun as Neptune, 2007 OR10 is currently twice as far from the Sun as Pluto.
