After centuries of studying the stars through telescopes, the arrival of the space age has enabled humanity to take a closer look at what we see, and don't see, in the night sky. Among the most powerful tools that space scientists have come to rely upon in studying other planets is remote sensing. With...

Rainbow-coloured jets in the cosmic cloud BHR 71 point to a celestial smash occurring 600 light-years away from Earth -- and NASA's Spitzer Space Telescope provides an exclusive peek at the "jet-setting" stars inside. The hot, young-stars can be seen in the Spitzer image (middle panel...

Title: Ages for illustrative field stars using gyrochronology: viability, limitations and errors Authors: Sydney A. Barnes We here develop an improved way of using a rotating star as a clock, set it using the Sun, and demonstrate that it keeps time well. This technique, called gyrochronology, pe...

The ESO Very Large Telescope Interferometer, which allows astronomers to scrutinise objects with a precision equivalent to that of a 130-m telescope, is proving itself an unequalled success every day. One of the latest instruments installed, AMBER, has led to a flurry of scientific results, an a...
