New data from the Planck telescope indicates that the universe is 13.82 Billion years old — 100 million years older than we thought.

New data from the Planck telescope indicates that the universe is 13.82 Billion years old — 100 million years older than we thought.

Planck launched into space in 2009 and has been scanning the skies ever since. It reads the cosmic microwave background radiation, which is the energy signature of the Big Bang, when the universe was born.

"This light started out as a white hot glow ... it would have been blindingly bright," Charles Lawrence, U.S. Planck project scientist at NASA's Jet Propulsion Laboratory, said in a press conference today. "During 13.8 billion years the universe has expanded and this light became a very cold glow that our eyes can't see."

Voyager 1 has left the solar system

Nasa disputes that the spacecraft has finally journeyed into interstellar space

There is no dispute that the little spacecraft Voyager 1 has boldly gone where no man-made object has gone before, but has it left our solar system?

That contention was made yesterday in a paper published in the little-known Geophysical Research Letters , the journal of the American Geophysical Union

Bee venom component might offer HIV protection

A component of bee venom packaged in super-tiny blobs can knock out HIV, a new study finds. Researchers testing the delivery system in lab dishes report that these nanoparticles attach to and destroy the virus without damaging cells, offering an early glimpse of a technology that might — with a lot more testing — prevent HIV infection in some people
