Halley’s Comet Meteors, Dazzling Mars And Halloween’s ‘Blue Moon’

Posted on

October is always a great month to go stargazing, and in 2020 it’s got some truly unmissable sights.

In the northern hemisphere October means longer nights, and when the clocks change it makes stargazing a possible in the early evening.

It’s also the month that the jewels of the winter night sky begin to return; the unmissable Andromeda Galaxy—the closest giant galaxy to our Milky Way—is becoming visible right after dark while towards the end of the month the sparkling Pleiades star cluster will rise in the east before midnight.

The planets are lingering. Jupiter and its four Galilean moons shine brightly in the southwest after dark with dimmer Saturn in tow, but this month it’s the turn of Mars to dominate post-sunset skies as it comes to opposition. Meanwhile, Venus sparkles in the pre-dawn skies.
