A Night with the Stars
Professor Brian Cox takes a celebrity audience through the most challenging concepts in physics from the lecture theatre of the Royal Institution of Great Britain. With the help of fellow scientist Jim Al-Khalili and guests Simon Pegg, Sarah Millican, James May and Jonathan Ross, he shows how diamonds are made up of nothingness, and how one such precious gem in the heart of London is in communication with the largest diamond in the cosmos. He also reveals how things can be in two places at once and why everything that people can see and touch in the universe actually exists.

Astronomers detect oxygen in space
For the first time, astronomers have found molecular oxygen, which makes up about 20 percent of our air on Earth, in space. Using the large telescope aboard the Herschel Space Observatory, a team of researchers from the European Space Agency and NASA detected the simple molecule in a star-forming region of the Orion Nebula, located about 1,500 light-years from Earth. This takes astronomers one step closer to discovering where all of the oxygen in space is hiding.

NGC 4755: A Jewel Box of Stars
The great variety of star colors in this open cluster underlies its name: The Jewel Box. One of the bright central stars is a red supergiant, in contrast to the many blue stars that surround it. The cluster, also known as Kappa Crucis contains just over 100 stars, and is about 10 million years old.

Men and women can now thank a dozen brain regions for their romantic fervor.
Researchers have revealed the fonts of desire by comparing functional MRI studies of people who indicated they were experiencing passionate love, maternal love or unconditional love. Together, the regions release neurotransmitters and other chemicals in the brain and blood that prompt greater euphoric sensations such as attraction and pleasure. Conversely, psychiatrists might someday help individuals who become dangerously depressed after a heartbreak by adjusting those chemicals.
Passion also heightens several cognitive functions, as the brain regions and chemicals surge. “It’s all about how that network interacts,” says Stephanie Ortigue, an assistant professor of psychology at Syracuse University, who led the study. The cognitive functions, in turn, “are triggers that fully activate the love network.” Tell that to your sweetheart on Valentine’s Day.
