Trihydrogen, H3+, is called the molecule that made the universe, where it plays a greater role in astrochemistry than any other molecule. While H3+ is astronomically abundant, no scientist understood the mechanisms that form it from organic molecules. Until now. Using lasers, Michigan State University scientists have unlocked the secret and published their results in the current issue of Scientific Reports...

‘Cold’ Great Spot discovered on Jupiter

The Great Cold Spot was first discovered on Jupiter using observations taken of Jupiter's auroral region by the CRIRES instrument on ESO's Very Large Telescope. The images on the left show the bright arcs of Jupiter's infrared aurora on two separate nights, the top left image on 17 October and three images taken 31 December 2012, as the planet slowly rotates. However, the Great Cold Spot cannot be seen clearly until these images are saturated so that the entire aurora becomes white, as shown on the right. Here, the planet glows as a result of the temperature of the upper atmosphere, and the distinct regions of cooling that reveal the Great Cold Spot can be seen. Based on data from VLT/ESO.
