Over the coming weeks we will feature, in no particular order, each of the final 16 selected images and winners will be announced by Royal Museums Greenwich on 17 September. The winning images are to be showcased at the Royal Observatory Greenwich in an exhibition opening 18 September.
Many of you may have tracked down an asteroid with binoculars or a telescope, but have you ever seen one with the naked eye? If not, then June presents you with an opportunity to see the brightest, 4 Vesta, at a close opposition. What’s more, ringed planet Saturn lies close by to act as a convenient guide.
If you’re an early riser in the British Isles, let the waning crescent Moon be your guide to three naked-eye planets – Mars, Jupiter and Saturn – at dawn on 18 and 19 March 2020. This celestial conjunction occurs in the constellation of Sagittarius where you can see all four Solar System bodies within the span of a fist at arm’s length. Look for attractive binocular conjunctions too.
Peering deep into the heart of our home galaxy, the Milky Way, the Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Most of the stars pictured in the image are members of the Milky Way nuclear star cluster, the densest and most massive star cluster in the galaxy. Hidden in the centre is the Milky Way’s resident supermassive black hole.
