AMNH Science Bulletins: Curiosity—Searching for Carbon

The Curiosity rover is seeking environments on Mars that could support life—or could have in the past. Earlier Mars missions found signs of water, but not organic carbon—life's essential building block. Watch the Curiosity team prepare to hunt for carbon at Mount Sharp, which holds a geologic record hundreds of millions of years old.

Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History.

Iowa Impact Crater Confirmed

From AGI Public Relations (Alexandria, VA) - Scientists have recently confirmed the existence of an impact crater buried below the town of Decorah, Iowa. Scientists first discovered what they thought resembled a crater in 2008, but now it has been corroborated by an airborne geophysical survey. Scientists estimate the diameter of the crater at 5.5 kilometers wide, nearly five times the size of the Barringer Meteor Crater in Arizona.

NASA's 2020 Mars Rover Science Goals

The Mars rover Curiosity is currently traveling the surface looking for past habitable environments.  In 2020, a new Martian rover will look for signs of past life, collect samples for possible future return to Earth, and demonstrate technology for future human exploration of the Red Planet.

The Closest Star System Found in a Century

WISE J104915.57-531906

You have probably heard of Alpha Centauri and Proxima Centauri, the closest known stars to the Sun.  About 100 years ago, Barnard's Star was discovered to be only about 1.5 light years further from us than the Alpha Centauri system. Just recently, though, a Penn State astronomer discovered the third closest star system to the Sun, but this time, instead of normal stars, this system includes "brown dwarfs", which are sometimes referred to as "failed stars".
