Glaciers' Rapid Retreat Should Be 'Alarm Bell To Everyone's Ears'
New studies show Antarctic glaciers are retreating at record pace.

There’s new data on Antarctica’s melting glaciers, and for anyone worried about the effects of climate change, it’s cold comfort indeed.

A pair of studies by researchers at NASA and the University of California at Irvine (UCI) show that glaciers in the continent’s western region are growing thinner ― and retreating at the fastest rate ever observed.

A broad expanse of glowing gas and dust presents a bird-like visage to astronomers from planet Earth, suggesting its popular moniker - The Seagull Nebula. This portrait of the cosmic bird covers a 1.6 degree wide swath across the plane of the Milky Way, near the direction of Sirius, alpha star of the constellation Canis Major. Of course, the region includes objects with other catalog designations: notably NGC 2327, a compact, dusty emission region with an embedded massive star that forms the bird’s head (aka the Parrot Nebula, above center). Dominated by the reddish glow of atomic hydrogen, the complex of gas and dust clouds with bright young stars spans over 100 light-years at an estimated 3,800 light-year distance.

Parece um quadro de Van Gogh, mas na verdade são nuvens na atmosfera de Saturno vistas pela sonda Cassini no infravermelho.
It looks like a Van Gogh’s painting, but actually it is a picture of Saturn’s clouds as seen in the infrared by the Cassini probe.

I have such a love/hate relationship with NASA like when you get their snapchats from the space station all like, omg look at the view tonite!!!1! #space #nofilter, all i want is to send them a snapchat back with the single star i can see from my window all like, look buddy not everyone can see the most incredible thing in the universe every night, like, check your privilege, NASA.

How the Apollo Lunar Modules were Smashed for Science

Each lunar module cost about $149,000,000; adjusted for inflation that’s just under one billion dollars per spacecraft. For all that money, not one was brought home to put on display in a museum. Not only was the Apollo lunar module not designed to survive reentry through the Earth’s atmosphere, each was abandoned or destroyed during its mission. The descent stages served as the launch pads for the ascent stages, so were all left in place on the Moon. The ascent stages, on the other hand, met a far more destructive end.

The story of the lunar module ascent stages goes hand in hand with the story of NASA doing seismic experiments on the Moon. Seismology, measuring how shock waves move across and through a planetary body, can tell scientists a lot about that body’s surface and internal structure. Seismologists do this on Earth by studying earthquakes, so NASA decided to do the same type of investigation on the Moon.
