The waxing crescent Moon passes close to Antares and is approaching Mars in the evening twilight. However, it may still be difficult to see for observers in the United Kingdom. Look out for Earthshine tonight – this is light reflected from the Earth that illuminates the darkened surface of the Moon, thereby allowing observers to see the whole of the Moon.
The images above depict the sky at 8:00 p.m. local time for Australia and North America and 5:45 p.m. for the United Kingdom.
