Free Astronomy Magazine November-December 2020

The 2021 edition of one of our most popular products, the ESO Calendar, is now available and can be purchased from the online ESOshop and in the ESO Supernova Planetarium & Visitor Centre. The calendar’s cover features a spectacular starscape around the relatively unknown central object, Gum 15, a nebula in which stars are being born. The image also features one of the closest supernova remnants to Earth, which exploded between 11,000 and 12,300 years ago and is located 800 light-years away from our cosmic home. For the month of March, the bright band of the Milky Way arcs above the ALMA antennas on the Chajnantor plateau. One of the closest stellar nurseries to Earth, the Orion Nebula, is the chosen image for July and the massive 3-tonne blank for the Extremely Large Telescope’s (ELT) secondary mirror is the star of September. Finally, in December the viewer will feel they are speeding towards the centre of our galaxy, thanks to a clever photographic technique used on an observation of the Milky Way. These are just a few highlights, we invite you to view the individual pages of the ESO Calendar 2021 here. The calendar has a total of 14 pages, and is available for 9.50 EUR in the ESOshop — but stock is limited so don’t delay!
