Emory University researchers have identified the first fish known to have switched from ultraviolet vision to violet vision (the ability to see blue light). The discovery links molecular evolution to functional changes in the organism and the environmental factors that drive those changes. Evolutionary geneticist and study leader Shozo Yokoyama says the findings, reported in […]
A two-hour exposure of Jupiter using a prototype Multi-Conjugate Adaptive Optics (MCAO) instrument mounted on the ESO’s Very Large Telescope (VLT) has produced the sharpest whole-planet picture ever taken from an Earth-based telescope. Taken by astronomers from the University of California, Berkeley, and the European Southern Observatory (ESO), the series of 265 snapshots reveal changes […]
A new adaptive optics system has allowed University of California – Los Angeles (UCLA) astronomers to capture the first clear pictures of the center of our galaxy, including the area believed to harbor a super-massive black hole. The new system allows the Keck telescope in Hawaii to “see” clearly through the distorting effects of the […]
