Brilliant Fireball Streaks Over U.S.
A brilliant, bright-green meteor blazed through the sky just north of Milwaukee, in U.S., early in the morning of Feb. 6 Credit: Space Science and Engineering Center (SSEC) and Department of Atmospheric and Oceanic Sciences, University of Wisconsin-Madison. The meteor streaked across the sky around 1:25 a.m., and likely landed in the Lake Michigan, according to American Meteor Society (AMS) operations manager Mike Hankey. He said the rock likely was the size of a minivan. The falling
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

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
