Jupiter and Venus light up the evening sky
A new ‘green’ comet for 2023
There’s a new comet in the sky which is already creating a flurry of interest among amateur astronomers, visible at the end of January and early February 2023. Don’t get your hopes up too high, but just be pleasantly surprised if you manage to spot it with binoculars.But don’t expect to see it looking green as the media hype says!
See all the planets at once!
The end of 2022 gives astronomers the chance to see all the planets, plus the Moon, in the evening sky at once. The last time this was possible from the UK was in October 1997 and it won’t be seen again until February 2025. The line-up will only be visible from the whole of the UK for a short time after sunset each evening and will require a clear view of the sky towards the south-west in particular. Uranus and Neptune are in the sky but will only be spotted after twilight.
