For an early astronomical treat to usher in the New Year, seek out the natural pyrotechnics of the rich Quadrantid meteor shower. Peak shooting star activity occurs within a four-hour window centred on a prediction of 8am GMT on 4 January 2020 – a time that favours UK skywatchers at astronomical dawn, or North American observers around local midnight.

Mars lies highest in the sky to the south soon after sunset at the beginning of July for observers in the UK, so you should not waste any opportunities to view the Red Planet while it is close and still relatively large in size. Tharsis, the great Martian volcanic plateau that is home to the largest volcanoes in the solar system, is turned toward Earth in the first week of the month.

Re-evaluating data collected 20 years ago by NASA’s now retired Mars Global Surveyor, researchers say the martian moon Phobos could have originated in the aftermath of a titanic planetary collision that blasted surface material into space.
