The older we get, the less we know (cosmologically)

(Phys.org) -- The universe is a marvelously complex place, filled with galaxies and larger-scale structures that have evolved over its 13.7-billion-year history. Those began as small perturbations of matter that grew over ...

NASA considers sending a telescope to outer solar system

Light pollution in our inner solar system, from both the nearby glow of the Sun and the hazy zodiacal glow from dust ground up in the asteroid belt, has long stymied cosmologists looking for a clearer take on the early Universe.

An alien code close to home: Seeking ET beyond the radio silence

Any intelligent extraterrestrial life that exists probably won't announce itself by blowing up the White House, or win over the hearts of children as a lovable alien with a glowing finger. Many scientists simply hope to find ...

Dark matter mystery deepens

(PhysOrg.com) -- Like all galaxies, our Milky Way is home to a strange substance called dark matter. Dark matter is invisible, betraying its presence only through its gravitational pull. Without dark matter holding them together, ...

Students plot experiments for YouTube Space Lab

Teenagers around the world on Monday were invited to design experiments that will be conducted on the International Space Station and streamed for all to see on YouTube.

Cosmic coincidence

Cosmologists tend not to get all that excited about the universe being 74% dark energy and 26% conventional energy and matter (albeit most of the matter is dark and mysterious as well). Instead they get excited about the ...

Scientists model physics of a key dark-energy probe

Ohio State University researchers are leveraging powerful supercomputers to investigate one of the key observational probes of "dark energy," the mysterious energy form that is causing the expansion of the universe to accelerate ...

New data suggests the universe is clumpier than thought

(PhysOrg.com) -- After analyzing data from the Sloan Digital Sky Survey (SDSK), cosmologist Shaun Thomas and colleagues from the University College of London, have concluded that the universe is "clumpier" than scientists ...
