In preparation for the imminent arrival of NASA’s Juno spacecraft, astronomers have used ESO’s Very Large Telescope to obtain spectacular new infrared images of Jupiter as part of a campaign to create high-resolution maps of the giant planet. These observations will help astronomers to better understand the gas giant ahead of Juno’s close encounter next month.
Some of the world’s leading amateur and professional astronomers are meeting on 12-13 May to prepare for a campaign of ground-based global observations in support of NASA’s Juno mission to Jupiter. Delegates from 13 countries in Europe and around the world are meeting at the Observatoire de la Côte d’Azur in Nice, France.
Scientists have determined that comets produce X-ray emission when particles in the solar wind strike the comet’s atmosphere. Recently, astronomers announced the results of a study using data collected with NASA’s Chandra X-ray Observatory of two comets — C/2012 S1 ISON and C/2011 S4 PanSTARRS — when both were relatively close to Earth.
