A team of scientists analyzed the chemical elements in the faintest known galaxy and determined that it is effectively a fossil galaxy left over from the early universe.
Astronomy & Space
Astronomy may well be the oldest science of all, seeking answers to questions such as: "Where did it all come from?" and "Are we alone?" But, today's astronomers are focusing on phenomena our forbearers never imagined—planets orbiting other stars, for example; black holes the size of our solar system; galaxies being driven apart by invisible "dark energy"; ripples in the fabric of space and time; and of course the big bang, where time itself began.
How do you detect planets that are hundreds of light years away?
A conversation with Daniel Whiteson and Jonathan Feng
Accelerators can probe artwork's origins
The segment used real satellite data and six computational models to create a vision that is both beautiful and scientifically accurate. Its long, swooping scenes reveal how different parts of the climate system interact at very different scales.
In this week's episode we discover the oldest fossil evidence of modern, venomous snakes in Africa. We discover what was going on in the earliest moments of our universe just after the Big Bang, and finally we learn about a new weather radar network in Texas.
Students and amateur astronomers in small western U.S. communities help scientists measure Kuiper Belt objects out beyond Neptune
Engineers have teamed up with a world-renowned origami expert to solve one of space exploration's greatest (and most ironic) problems: lack of space.
This week's episode explores silicon chip technology that could possibly extend cell phone battery life, babies and higher math ability, a drone helping farmers better manage their crops, and finally how more than 83,000 volunteer citizen scientists helped an international research team catalog over 300,000 nearby galaxies.
This short teaser video introduces us to the mission of Firefly, a CubeSat built by undergraduate students with the partnership of Goddard Space Flight Center and the National Science Foundation.
Members of the Dark Energy Survey collaboration explain what they hope to learn by studying the southern sky with the world's most advanced digital camera, mounted on a telescope in Chile.
Several different types of stars and their flickers translated into audio files
The cosmic fireworks that characterize a starburst galaxy can abruptly fizzle out after only a relatively brief period of star formation, and astronomers want to know why.
This week's episode of NSF Science Now explores sea turtle locomotion by researchers at Georgia Institute of Technology, new images from the Gemini North telescope of comet ISON, also how researchers at the University of Illinois at Urbana Champaign have created the first digital cameras that mimics insects' unique, 180-degree vision and finally we'll explore Antarctica through a unique Rutgers University program documentary about science on the frigid continent.
NSF Science Now series spotlights NSF science and engineering research and discoveries
We depend on the Sun for heat and light, but there's a lot more going on than meets the eye," says NCAR solar physicist Scott McIntosh. On a whirlwind tour of the Sun's magnetic forces, MacIntosh describes the impact solar storms can have on Earth's environment and explains how scientists study this powerhouse of mass and energy.
U.S. astronaut Tom Marshburn and Canadian astronaut Chris Hadfield, both on board the International Space Station as part of Expedition 34, sent greetings and congratulations for the inauguration of ALMA, March 13, 2013.
The impact of comets on the surface of Jupiter are a fairly common experience. At the University of Central Florida, astronomers Joseph Harrington and Csaba Palotai are leading a project that studies precisely how these impacts happen, and also provides valuable information about what might happen if such a comet struck Earth.
Using new technology at the telescope and in laboratories, researchers have discovered an important pair of prebiotic molecules in interstellar space.
When a meteor hits the earth, there is the possibility that it brings something very rare along with it: cosmic stardust older than our Solar System.
