Water is the most abundant yet least understood liquid in nature. It exhibits many strange behaviors that scientists still struggle to explain. While most liquids get denser as they get colder, water is most dense at 39 degrees Fahrenheit, just above its freezing point. This is why ice floats to the top of a drinking glass and lakes freeze from the surface down, allowing marine life to survive c Netherlands completes deal to buy PAC-3 missile defense units

The U.S. Air Force has selected the 179th Airlift Wing base in Mansfield, Ohio, as the location for the Air National Guard's first Cyber Warfare Wing.
Col. Todd Thomas, 179th Airlift Wing commander, said in a press release Thursday it would be a difficult transition, but a change that he strongly believes the airmen can make.

The study of active asteroids is a relatively new field of solar system science, focusing on objects that have asteroid-like orbits but look more like comets, with visual characteristics such as tails.
Because finding an active asteroid is such a rare event, fewer than 30 of these solar system bodies have been found since 1949, so there is still much for scientists to learn about them. Roughly only one out of 10,000 asteroids are classified as active asteroids, so an enormous number of observations will be needed over the span of many years to yield a larger sample for study.
Through funding from a National Science Foundation (NSF) Graduate Research Fellowship Program (GRFP) award in 2018, doctoral student Colin Orion Chandler in Northern Arizona University's Department of Astronomy and Planetary Science just launched an ambitious new project, Active Asteroids, which is designed to engage volunteers in the search for more of these enigmatic objects.
