Moon's Age Estimated to be Slightly Less Than 4.5 Billion Years

A NASA-funded research team led by Dr. Bill Bottke of Southwest Research Institute (SwRI) independently estimated the Moon's age as slightly less than 4.5 billion years by analyzing impact-heated shock signatures found in stony meteorites originating from the Main Asteroid Belt. Their work will appear in the April 2015 issue of the journal Science.

Quenching of Star Formation Spreads from Galaxy Cores to the Outer Parts

Astronomers have shown for the first time how star formation in “dead” galaxies sputtered out billions of years ago. ESO’s Very Large Telescope and the NASA/ESA Hubble Space Telescope have revealed that three billion years after the Big Bang, these galaxies still made stars on their outskirts, but no longer in their interiors. The quenching of star formation seems to have started in the cores of the galaxies and then spread to the outer parts. The results will be published in the 17 April 2015 issue of the journal Science.

Formamide Biomolecule Detected in Five Protostellar Clouds

Complex organic molecules such as formamide, from which sugars, amino acids and even nucleic acids essential for life can be made, already appear in the regions where stars similar to our Sun are born. Astrophysicists from Spain and other countries have detected this biomolecule in five protostellar clouds and propose that it forms on tiny dust grains.

Alma Reveals Extremely Powerful Magnetic Field Very Close to Supermassive Black Hole

Astronomers from Chalmers University of Technology have used the giant telescope Alma to reveal an extremely powerful magnetic field very close to a supermassive black hole in a distant galaxy. The results appear in the 17 April 2015 issue of the journal Science.

Researchers Design All-Photonic Quantum Repeaters for Quantum Cryptography

Imagine having your MRI results sent directly to your phone, with no concern over the security of your private health data. Or knowing your financial information was safe on a server halfway around the world. Or sending highly sensitive business correspondence, without worrying that it would fall into the wrong hands.

Cornell Professor Honored with 2015 John Bardeen Prize for Theoretical Research

Vinay Ambegaokar, the Goldwin Smith Professor of Physics Emeritus, has been awarded the 2015 John Bardeen Prize in recognition of his theoretical research, which has substantially advanced understanding of unique and fundamental features of superconductivity. The late Bardeen is the only person to be awarded two Nobel Prizes in physics.
