Here's an illustrated view from Feb 2 with Mercury, Venus and the quarter Moon across the evening sky along the ecliptic at their respective angles away from the Sun. Mercury is nearing its angle of greatest elongation on Feb 10. A quarter Moon is always 90° from the Sun.pic.twitter.com/wojcDf4Yzu

Someone asked me to do an explainer for why we only see one side of the Moon, showing that it still rotates. Well, accumulating so many animations now that I can say "here's one I made earlier!" –pic.twitter.com/UZYKBZw49p

And today SpaceX launched another set of 60 satellites to litter the sky, while the ones already in orbit risk colliding. We’ve trashed the Earth now we’re trashing the sky. All for profit.https://twitter.com/physhelp/status/1222522797471059969 …

The brightest planet meets the faintest, as Venus passed 1/4 of a degree (very close!) by Neptune on Jan 27, with both worlds near 4th magnitude Phi Aquarii, all in the blue twilight.

This is Comet
#PanSTARRS C/2017 T2, the green glow, passing above the Double Cluster in Perseus last night, Jan 25. The comet might brighten later this spring. Let's hope!@universetoday@SkyNewsMagazine@skyatnightmagpic.twitter.com/aTQZBAPAOG

Orion on January 25 with Betelgeuse still dim, here in two views: sharply focused and defocused to better show the stars' brightness. To the eye and camera
#Betelgeuse looked similar to magnitude 1.6 Bellatrix. I don't see it brightening yet.@universetoday@SkyNewsMagazinepic.twitter.com/nkmr5agOVG

This Sunday, Jan 26, at ~21:45UT (16:45 EST, 14:45 CET),
@NASASun Parker Solar Probe will break its own record to become the fastest human-made object in history!
At that time it'll exceed 95.3km/s, and go on to reach a disturbingly fast 109.2km/s on Jan 29 (~09:40UT)!

Betelgeuse! Getting all the attention lately for being dim. And it is! About a magnitude fainter than usual and getting dimmer? This was Jan 22, with the red giant in a telescopic close-up set in the rich starfields of Orion.

The comet, C/2017 T2 PanSTARRS, that might brighten to become a decent binocular object later this spring. On Jan 22 it was approaching the Double Cluster in Perseus as a green blob at top here.

Scorpius in the snow! Here he is rising at dawn on Jan 21, accompanied by Mars (above reddish Antares — the "rival of Mars" — at right of centre) and the waning crescent Moon at left.
