Know Your Ocean
Even though the ocean covers seventy percent of the Earth’s surface, people tend to know more information about land than the sea. As a result, our understanding of the ocean is often incomplete or full of misconceptions. How well do you know the ocean?

Astronomers discovered a possible magnetar that emitted 40 visible-light flashes before disappearing again.
Magnetars are young neutron stars with an ultra-strong magnetic field a billion times stronger than that of the Earth. The twisting of magnetic field lines in magnetars give rise to ”starquakes”, which will eventually lead to an intense soft gamma-ray burst.
In the case of the SWIFT source, the optical flares that reached the Earth were probably due to ions ripped out from the surface of the magnetar and gyrating around the field lines.
French photographer Thierry Cohen wants to show you what the cities might look like if they went dark on a clear day, and if the photographer focused on bringing out the stars. His project Darkened Cities shows recognizable cityscapes in darkness under the night sky.
To create the images, Cohen first traveled to locations that are untainted by the light pollution of large urban areas, capturing beautiful night shots of the Milky Way floating overhead.
He then combined these photographs with manipulated photographs of various cities (e.g. San Francisco, New York City, Tokyo, Rio de Janerio) to complete the effect.
