Life in the Universe, Reflected by the Moon

Earthshine – a poetic, fanciful word for the soft, faint glow on the Moon when the light from the Sun is reflected from the Earth's surface, onto the dark part of the Moon. And as unlikely as it might seem, astronomers have used Earthshine to verify there’s life in the Universe: Us. While we already know about life on our own world, this technique validates that faint light from distant worlds could also be used to find potential alien life.

“We used a trick called earthshine observation to look at the Earth as if it were an exoplanet,” said Michael Sterzik from the European Southern Observatory. “The Sun shines on the Earth and this light is reflected back to the surface of the Moon. The lunar surface acts as a giant mirror and reflects the Earth’s light back to us — and this is what we have observed with the VLT (Very Large Telescope).”

The Nerdiest Video Game Ever!



New iPhone game is first NOAA app and only the second NASA game app. Just as with the real GOES-R, the challenge with Satellite Insight is to keep up with the massive influx of weather and other environmental data.

NASA has a job opening. Wanted: People of all ages to sort, stack, and catalogue terabytes of simulated data from a satellite that launches in 2015. Agile thumbs required.

Sorting terabytes of data? It's more fun than it sounds.

In fact it's a game: Satellite Insight. The Space Place Team at the Jet Propulsion Laboratory created the entertaining app for iPhones to get the word out about GOES-R, an advanced Earth science satellite built by NOAA and NASA. Described by the Los Angeles Times as possibly the nerdiest game ever,"Satellite Insight" may be downloaded for free from Apple's app store. Be careful, though, once you start playing it's hard to stop. Some reviewers have likened it to Tetris, one of the most popular video games of all time.

Recent Geologic Activity on the Moon?


Newly detected series of narrow linear troughs are known as graben, and they formed in highland materials on the lunar farside. These graben are located on a topographic rise with several hundred meters of relief revealed in topography derived from LROC stereo images. Image Credit: NASA/GSFC/Arizona State University/Smithsonian Institution.

Recent images from NASA’s Lunar Reconnaissance Orbiter Camera provide evidence that the lunar crust may be pulling apart in certain areas. The images reveal small trenches less than a kilometer in length, and less than a few hundred meters wide. Only a small number of these features, known as graben, have been discovered on the lunar surface. There are several clues in the high-resolution images that provide evidence for recent geologic activity on the Moon.

Skydiver Prepares for Record-Setting Freefall from the Edge of Space



In 2010, we reported on Felix Baumgartner and his upcoming attempt to break the sound barrier with his body, in a freefall from the edge of space. Part science experiment, part publicity stunt, part life-long ambition, the Red Bull Stratos mission will have Baumgartner traveling inside a capsule with a stratospheric balloon to 36,500 meters (120,000 feet), where he will step out and attempt a record-setting highest freefall jump ever. The mission was delayed by two years by a lawsuit, but Baumgartner’s jump is now back on, and will be attempted later this year, perhaps late summer or early fall 2012.

Hubble’s 1923 Nova in Andromeda Erupts Again!




On December 11, 1923, Edwin Hubble discovered a nova in the Andromeda galaxy. Novae occurring in our Milky Way’s sister galaxy have proven to be not that uncommon, as there have been over 800 novae detected in M31 in the last 100 years. Hubble’s 1923 discovery became known as M31N 1923-12c, the third nova discovered in December of 1923.

Product Spotlight - Meade 6" SCT LS LightSwitch Telescope

For a lot of telescope users, aligning the telescope is always a frustrating experience - even when it is considered a "Go To". There's always something you have to know... Be it the perfectly correct time, the date, your latitude or longitude. How many new users have been stumped by not knowing the names of the alignment stars? Or not being able to see an alignment star that is blocked by a tree or a house? All of these little things can add up to beginning an observing evening in an unpleasant way and that's not what enjoying astronomy is all about.
