Got a western facing window? Have need to be 'just getting up' in the night? Combine the two, have a peep out to the west around 3 or 4am if you're up and about.
Venus as a morning star* just now is absolutely stunning; shining bright like a miniature moon; no wonder, as Lucifer the light-bringer, it played such a part in the communual psychey in days gone by. It is a major object in the sky and much over-looked: it is nothing short of awesome! Pre-light-polution or out on the moors it must have been utterly magnificent.
I would imagine also - in fact I'm certain, that if you marked its position above the horizon just at sun rise - by so many fingers' width at arms-length - that you would be able to spot it during the day the same distance ahead of the sun.
Lots of cool points on offer there!
Ahem, - east facing window for morning planets
Jupiter and Saturn are good in the west in the evening though.
How strange. Ta.

There's a possible announcement tomorrow of a suggestion of evidence for life on Venus

An article on EarthSky.org that seems to have jumped the gun on an embargo date, then removed, but was Google Cached,

ETA - almost did an LPM on that one...

My avatar was a scientific result that was later found to be 'mistaken' - I rarely claim to be 100% correct
ETA 5/8/20: I've been advised that the result was correct, it was the initial interpretation that needed to be withdrawn
Meta? I'd say so!

I remember when there was discussion of what might have been microbial remnants on a bit of Mars rock, mid to late 1990s, Terry Pratchett said something close to "I want so much for this to be true that I hope the scientists are trying their hardest to prove that it isn't". I couldn't have phrased it better.

Well I did find Phosphine Detected In The Atmosphere of Venus

It wouldn't be such a good sign if phosphine were detected in the atmosphere of my lab.

Ah well, it looks as though the paper about the black hole at the centre of the Earth has been retracted now:

Have you considered stupidity as an explanation

This probably has more information about Space Mission Operating Systems than you need, but it is an interesting read.

Early tomorrow evening, if it's clear, you can put extend your arm and your fist can cover over 79% of all the moons in the Solar System.

The Arecibo Telescope can't be repaired after it's last hurricane damage, and will now be decommissioned.

with a 900-ton instrument platform hanging 450 feet above
900 tons! that's 30 centurion tanks worth!
(And wiki concurs)
In the pics it looks like two open girder cradles -some large stage lighting gantries- with the technical gubbinry hanging below, wouldn't have said it was more than ten tons.
Them's some cables and pylons!
