Why so many asteroid close approaches lately?
Every month about 40 known or recently discovered asteroids come within 0.05 astronomical units, or about 19 lunar radii, from our planet. In some cases, such as in the month of December 2016, four or even five objects reach their closest approach distance on the same day. Clusters of asteroid flybys often attracts the interest of the media and of the public, but are these occurrences unusual? Upon applying statistical considerations to the present discovery

Reported by Victor Bar, NEOShield-2 Agent in Israel At the beginning of the school year, a first of its kind project has began for the 8th grade gifted students of Ahad Haam Junior High School at the city of Petach-Tikva in Israel, the asteroid threat and mitigation measures based on the NEOShield-2 project. After having an online meeting with the school principal manager, teachers, parents and the NEOShield-2 Public Outreach coordinator, we created the project format
Newly lab-made metallic hydrogen could revolutionize spaceflight
After almost one century of being predicted by physicists, metallic hydrogen is claimed to be a reality according to two scientists from Harvard University, Professor Isaac Silvera and Dr. Ranga Dias. The scientists described this rare creation in a paper published in Science on January 26. “This is the holy grail of high-pressure physics,” Professor Silvera explained. “It’s the first-ever sample of metallic hydrogen on Earth, so when you’re looking at it, you’re looking at
New study on Ceres’ surface shows: asteroids might be camouflaged
Ceres is the largest object in the asteroid belt and for being much larger than the rest of the other objects it was classified as a dwarf planet in 2006. Since first discovered, in 1801, Ceres has been surprising scientists and the latest study on its surface just deepened the mystery around the dwarf planet. Using data primarily gathered by SOFIA, NASA’s Stratospheric Observatory for Infrared Astronomy with DLR partnership, a team
