Playing silly games with Google Maps, looking for the longest route by car it can still calculate (many East Asian destinations don't work) - is this it? Also learned that driving from Germany to Capetown takes 7 days while to Kabul it's only 3. Vacation planning made easy ...;-)
My first chance to go look for comet

from 51.4°N in Witten, Germany, this morning - and it WAS SO EASY! Naked eye, tail included, for some 35 minutes in astronomical and nautical twilight - and what a beauty, a 'real' comet. Facts and pics:

Plasma physics in space is (often) crazy ... like in the ion tail of comet SWAN on May 5th as brilliantly documented by Gerald Rhemann with a remote 12" telescope in Namibia: help yourself to many more of his comet pictures in (some mosaics included).
The often overlooked explanation why the Soviet Union was ahead of the U.S. for several years in the original space race ... Korolev had two telephones, von Braun only one.
Only now became aware of a spectacular detection of the aftermath of the - by now famous - Bering Strait bolide of 18 Dec. 2018 with the Terra satellite's MODIS instrument in its frame - here is a darkened version to better bring out the hovering cloud.
Bow to the masters ... the leading Austrian cometographers Gerald Rhemann and Michael Jäger just published these images of

And the winner - for the coolest comet-rise picture - today is ... just as yesterday the lonely Swiss Alps webcam ! Wonder if there is *anyone* on that mountain - on in the villages below - having a *look* at this rare sight.

Never say never in space science appreciation ... when the 'first image of a black hole' was published a cynical colleague predicted nobody would care - we now know from media analysis that several billion inhabitants of this planet have been exposed to it. Just give JWST time.

Unless Santa's HQ is at the *South* Pole where it's summer at X-mas (and any claims that it is in the European Arctic are merely to distract thieves).
Had an outstandingly clear view of the beautiful cosmic trio today from Königswinter-Heisterbacherrott, Germany, between 16:00 and 17:00 UTC, with Jupiter and Saturn almost exactly a lunar diameter from each other, 4 days before the Great Conjunction. More pictures later tonight.

Heute - in Bochum - von 3:05 bis 4:00 MESZ war der Komet klasse zu sehen, davon 1/2 Stunde mit bloßem Auge: in viele Details. Zum Aufsuchen gut geeignet: (aber mit dem Fernglas unter Capella den Horizont absuchen reicht auch schon).
By far the best

Whoa!!! A looong chromospheric arc between the cusps of the solar crescent over Pakistan in a brilliant photograph by Talha Moon Zia, shared here by permission: see for the source.
Congratulations, Hubble Tension! As I just learned in a webinar (slides from A. Riess and D. Huterer) the hard 'local' constraints on the Hubble Constant and the CMBR determination are now over 5 sigma apart ... which in particle physics would constitute a major discovery. ;-)

17 new raw images from
@NASAInSight
- all from today - have turned up on , bringing the total to 46: the robot arm camera has been busy looking in all corners of the spacecraft and on the ground it has landed on.
Sad but true: according to an internal Max Planck Institute mail to the scientists that was leaked to me, "during the ground contact this afternoon we placed eROSITA into safe mode. It is currently unclear when a return to normal operations will be possible."
At 5:39 UTC today the Hubble Space Telescope is exactly half as old as the whole space age! In the sense that the HST was launched 11889.712 days or 32.55 years ago then - and Sputnik 1 was launched precisely twice that long ago. (Picture: Hubble's release on 25 April 1990.)

Seeing this live with an open mouth I wondered whether a staging has *ever* been filmed in such quality from the ground. I mean since 1957.
Whoa, an unexpectedly dramatic high-extinction moonset! For the naked eye the Moon was dimmed so much it could hardly be seen anymore - but here and in (bottom) and (top) is what the camera saw, with high ISO and long exposures ...

Breaking News, literally! There is a star explosion under way in Perseus (near Capella in Auriga actually), with 6th magnitude - and it could be a unique nova eruption happening to a known dwarf nova, V392 Persei: in I show a chart and provide some links.
