In this video, Fermilab's Don Lincoln tells about the big bang theory and sketches some speculative ideas about what caused the universe to come into existence.
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.
This is a physically accurate gravitational lensing visualization of the last few orbits of a binary black hole merger. The camera is above the orbital plane of the merger, looking down.
Over a cup of coffee, astrophysicist Dan Evans chats about black holes, his research and what's on the horizon.
The deputy physics coordinator for CERN's CMS experiment Darin Acosta explains what we know about the Higgs boson and what remains to be discovered. NSF funds the CMS (Compact Muon Solenoid) experiment, which is investigating a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter.
NRAO Director Tony Beasley discusses the impact of ALMA's new high resolution observations of HL Tau.
The National Science Foundation-funded National Radio Astronomy Observatory expands on a news release related to Atacama Large Millimeter/submillimeter Array's (ALMA) high-resolution capabilities.
NSF-funded BICEP2 collaborators confirm cosmic inflation, a cataclysmic event that followed a fraction of a second after the Big Bang
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.
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.
