Just six light-years away, Barnard's star moves in Earth's night sky faster than any other star. This red dwarf, smaller and older than our Sun, is among the least active red dwarfs known, so it represents an ideal target to search for exoplanets. Now, an international team led by researchers from the Spanish National Research Council (CSIC) has found a cold Super-Earth orbiting around the Barnard´s star, the second closest star system to Earth.
An international team including five Carnegie astronomers has discovered a frozen Super-Earth orbiting Barnard's star, the closest single star to our own Sun. The Planet Finding Spectrograph on Carnegie's Magellan II telescope was integral to the discovery. To find this cold Super-Earth, the team combined 20 years of data from seven different instruments, all of which were 'stitched' together to form one of the largest and most-extensive datasets ever used for this method of planet detection.

Earth's water may have originated from both asteroidal material and gas left over from the formation of the Sun, according to new research. The new finding could give scientists important insights about the development of other planets and their potential to support life.
When planet Earth formed, it grabbed a lot of hydrogen, a precursor to water, from the gas surrounding the newborn Sun. This source has long been neglected for geochemical reasons now shown to be incorrect.
Galaxy evolution can be chaotic and messy, but it seems that streams of cold gas spraying out from the region around supermassive black holes may act to calm the storm.
The cosmos is a void dotted with stars and an ever-increasing number of newly-observed planets beyond our solar system. Yet, how these stars and planets formed out of clouds of interstellar dust and gas remains mysterious. The study of black holes provides clues that could help solve this mystery.
Combined observations of Comet McNaught -- one of the brightest comets visible from Earth in the past 50 years -- have revealed new insights on the nature of comets and their relationship with the Sun.
