President Obama Meets U.S. Laureates of 2010 Kavli Prizes

At the White House, President Barack Obama met the seven U.S. recipients of the 2010 Kavli Prizes to recognize and honor their seminal contributions to the three fields for which the Prizes are awarded -- astrophysics, nanoscience and neuroscience.


Cambridge academic honoured in leading cosmology award

Professor George Efstathiou, Director of the Kavli Institute for Cosmology in Cambridge, is one of four astronomers who have won this year’s Gruber Cosmology Prize.


Study Reveals Milky Way among Oddball Four Percent

New research shows our home galaxy belongs to a rare subset among the billions that populate the cosmos.


Fermi's Large Area Telescope Spots 'Superflares' in the Crab Nebula

The famous Crab Nebula supernova remnant has erupted in an enormous flare five times more powerful than any flare previously seen from the object. On April 12, NASA's Fermi Gamma-ray Space Telescope first detected the outburst, which lasted six days.


Researchers Find Two Distinct Components of High-Energy Emission from Direction of the Sun

The first 18 months of Fermi's Large Area Telescope (LAT) observations of the Sun have been combed through, and a research team reports that there are two distinct components of emission from the direction of the Sun.


"Reconstructing the Earliest Stars" in Physics Today

The April 2011 issue of Physics Today features a cover story on how cosmologists use computer simulations to gian insights written by KIPAC's Tom Abel.


Clearest Picture Yet of Perseus Galaxy Cluster

X-ray observations made by the Suzaku observatory provide the clearest picture to date of the size, mass and chemical content of a nearby cluster of galaxies.


Fermi's Large Area Telescope Sees Surprising Flares in Crab Nebula

The Crab Nebula is shocking scientists with gamma-ray flares set off by the most energetic particles ever traced to a specific astronomical object, leading researchers to rethink their ideas of how cosmic particles are accelerated.


Astronomers Detect First Carbon-Rich Exoplanet

A team led by a former postdoctoral researcher in MIT’s Department of Earth, Atmospheric and Planetary Sciences and the MIT Kavli Institute for Astrophysics, recently measured the first-ever planetary atmosphere that is substantially enriched in carbon.


Galaxy Clusters Shine New Light on Dark Energy

Scientists' murky understanding of dark energy may have just gotten a little clearer, thanks to recent work by a team of researchers that includes astrophysicist Neelima Sehgal of the Kavli Institute for Particle Astrophysics and Cosmology at SLAC.
