Is Einstein finally wrong? Far-off galaxies are tugging each other more tightly than Einstein’s gravity theory predicts, suggests an analysis of light from distant stars.
Now available in an online physics paper archive, the analysis by Cornell cosmologist Rachel Bean looks at how galaxies attract one another roughly one billion light-years away.

From our friends at NASA:
NASA’s Moon Mineralogy Mapper, an instrument on the Indian Space Research Organization’s Chandrayaan-1 mission, took this image of Earth’s moon. It is a three-color composite of reflected near-infrared radiation from the sun, and illustrates the extent to which different materials are mapped across the side of the moon that faces Earth. Small amounts of water were detected on the surface of the moon at various locations.
This image illustrates their distribution at high latitudes toward the poles. Blue shows the signature of water, green shows the brightness of the surface as measured by reflected infrared radiation from the sun and red shows an iron-bearing mineral called pyroxene.
