Qr Bbpost Mother of Pearl clouds!  Those are very rare- how often do you get to see them there?

A few times a year here, usually between December and February.  They typically form over the mountains.

Since I moved a bit uphill with a view many years ago, low clouds have been something which never fails to fascinate.  It can be really nice to look out of the window in the morning to discover that the city is gone and replaced by a white plain or desert changing every minute.  Here's a little coll...

36945 I actually thought space began where the exosphere merges with space, which would be around 600 miles or 1000 km up. There's no hard limit, but 100 km is often used, though this is way to low for an orbit.  Fast moving meteors will leave a glowing trail up to 120-130 km, so the atmosphere sti...

36897 By the way the Spacer era has now begun, Sir Richard Branson just launched into space! https://twitter.com/i/events/1414167242728644622 He reached an altitude of 53.5 miles. "Poor man's space".  Surely an awesome experience, but in my opinion, suborbital flights don't really count.

Actually,  I think we could keep all the CO2 on Mars if we could add enough nitrogen, oxygen and water to get at least the pressure we have on Earth.  But even though Mars is cold, such an atmosphere would eventually leak due to Mars' low gravity.

Floating cities of Venus is an old idea, and might not be a less far fetched idea than permanent bases on Mars.  In both cases the communities will be highly dependent on Earth for supplies.  Such settlements are basically space stations with extra challenges.  There is no "second Earth". ...

Unusual weather

It's going to be pretty hot on Sunday even at 66 degrees north in Norway.  The national record is 35.7C, which will probably stand, and the local record for this place is 35.0C.  This is the forecast for Mosjøen:

Most such UFO videos from aircrafts appear to be illusions of some kind.  Like parallax effects and misjudged distances, which can make the object (birds or whatever) appear to have insane speed.  It's hard to tell from the videos alone, but if we had the speed, altitude, focal length and other data...

No filters or eclipse glasses necessary.  Just lucky to see anything through the clouds.

Qr Bbpost  How fa away are we from hover cars?

If the cars are locked to magnetic tracks, it's really a train, isn't it?  And in a future like that personal cars have become obsolete.
