On dark energy...

It is interesting but...not sure if I would claim the word 'final' as the final word about it. There are variants and diverse routes on this path. Possibly the 'path integral' has not yet fully unfold. Nature is amazing and, moreover, tentative theories do provide a wide range of scenarios to consider. https://www.forbes.com/sites/startswithabang/2019/07/26/we-have-already-entered-the-sixth-and-final-era-of-our-universe/

As the new PM walks into Number 10 he will be greeted with applause by Downing Street staff - but there is one employee who is notoriously hard to impress.
Larry the cat currently holds the official role of Chief Mouser to the Cabinet Office, a position that's said to date back hundreds of years.
So how have previous PMs warmed to their four-legged civil servant over the years? A cross-species special relationship or a classic case of feline indifference? 
 
 

Zodiacal Road

Explanation: What's that strange light down the road? Dust orbiting the Sun. At certain times of the year, a band of sun-reflecting dust from the inner Solar System appears prominently just after sunset -- or just before sunrise -- and is called zodiacal light. Although the origin of this dust is still being researched, a leading hypothesis holds that zodiacal dust originates mostly from faint Jupiter-family comets and slowly spirals into the Sun. Recent analysis of dust emitted by Comet 67P, visited by ESA's robotic Rosetta spacecraft, bolster this hypothesis. Pictured when climbing a road up to Teide National Park in the Canary Islands of Spain, a bright triangle of zodiacal light appeared in the distance soon after sunset. Captured on June 21, the scene includes bright Regulus, alpha star of Leo, standing above center toward the left. The Beehive Star Cluster (M44) can be spotted below center, closer to the horizon and also immersed in the zodiacal glow.

BBH -> GWs

The Honourable Schoolboy

Not most recent but worthy to think about, if looking up, N-hemisphere, towards about N-E or NW, compass location hourly dependent. BBH. And yes, a graphic location of the top source of GWs. Up there... You can really see the area, from your balcony, window.... And if you want to know more (You should, U know...) please have a look at http://grg.uib.es/publico/ . Very nice, really.
