It’s actually so true
I'm Bob Wilton & this is my blog Skyward Awe. Posts revolve around Astronomy & Aviation, however anything science related is likely to show up.
The sun is about to come up over the South Pacific Ocean in this colorful scene photographed by one of the Expedition 35 crew members aboard the Earth-orbiting International Space Station between 4 and 5 a.m. local time, May 5, 2013.
The space station was at a point above Earth located at 27.4 degrees south latitude and 110.1 degrees west longitude, a few hundred miles east of Easter Island.

Sounding Off in the Ionosphere
Last night, NASA launched a pair of rockets from the Marshall Islands to paint the upper atmosphere red and white. It was part of a project called EVEX designed to observe special “neutral winds” in the ionosphere.
The ionosphere extends into what we call “outer space”, and is part of Earth’s electromagnetic shield protecting us from solar sterilization. When low-energy sunlight reacts with the upper atmosphere, we see a phenomenon called “airglow” (which you’ll probably recognize from photos like this). When high-energy particles from the solar wind strike the polar upper atmosphere, we get auroras (click here to learn more about those).
Of course, that means that disturbances way up there can block important signals like GPS transmissions, which makes generals and smartphone users rather angry. So to study how odd ionosphere winds can cause glitches, NASA launched two rockets a few minutes apart, each arriving simultaneously at different ionosphere altitudes. They released harmless chemicals that react with the thin air to make brilliant clouds that can be tracked from the ground.
It also kind of looks like a space ghost-baby is about to be made.
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?

This concludes my tumblog, my thanks to all who followed. I hope it was enjoyed.
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.
