Active galactic nuclei (AGN) are among the most dramatic and interesting phenomena in extragalactic astronomy. [38] A new study conducted by a team of astronomers from Poland and South Africa provides more insights into the nature of Hen 3-160, a symbiotic binary system in the southern Milky Way. [37] There are more than 3,900 confirmed planets beyond our solar system. Most of them have been detected because of their "transits"—instances when a planet crosses its star, momentarily blocking its light. [36] Rice University physicists have created the world's first laser-cooled neutral plasma, completing a 20-year quest that sets the stage for simulators that re-create exotic states of matter found inside Jupiter and white dwarf stars. [35] An international group of astronomers has detected an intense and extremely luminous gamma-ray flare from one of high-redshift blazars known as DA 193. [34] Our universe could be the mirror image of an antimatter universe extending backwards in time before the Big Bang. [33] "As you celebrate New Year's Day, cast an eye upward and think for a moment about the amazing things our country and our species can do when we set our minds to it," Stern wrote in the New York Times on Monday.
