For those reasons the world should focus immensely on how energy can become cheaper.  Extracting oil, coal and gas is a complex operation, and reservoirs are diminishing, so these energy sources will for the most part become obsolete if energy prices drop.

35376 a day time meteor!  I wonder how bright that was? Roughly full moon brightness.  Only sort of daytime.  It's polar night and the sun was 6 - 7 degrees below the horizon, so it was twilight.  Only Mars and a few bright stars were visible (if you know where to look).  The shallow angle and the ...

More good stuff.  This was a northern Taurid, an unusually bright meteor belowing to this swarm.  The entry mass was probably several 10's of kilos.  The Taurids and comet Encke probably belong to an older comet which disintegrated.  The cameras in Skibotn are new and I calibrated them last night.  ...

This is pretty sad, was this still the largest radio telescope in the world?

No, FAST is larger.  Still sad, though.

To me healthy means reasonably varied and a quantity matching your activity level.  Which does not exclude junk food, unless a single junk food meal matches your activity level so it becomes the single meal of the day.

I've seen the "healthy food" is too expensive argument many times, but really?  Healthy food doesn't need to be anything fancy.  In fact, one healthy bit in this is not to eat too much, which naturally makes things cheaper.  Sounds to me like a convenient excuse for not bothering to prepar...

Not sure where those numbers are from, but in Norway I think it's up to 80% if low pay, less if you earn more.  This is regardless of covid-19 if you lose your job, but the duration has been temporarily extended from half a year to almost a year because of covid-19.  Beyond that period other options...

Sigh.  "Emergency" because some statistics, which in a sane world only weather nerds would find interesting, has become tabloid.  I don't know what "go green" means in NZ, but doing things based an imagined emergency generally doesn't result in quality decisions.  The takeaways, ...

More on the fireball in Japan.

News reports on fireballs are certainly on the rise in recent years.  The reason is of course that there are many more high quality surveillance cameras.  These videos are effective click-baits.

Some finds  for Covid-19 by health authorities in Norway (data from 1 June through 30 November): Mortality rate by age: 0-39: 0.0022% 40-59: 0.020% 60-69: 0.18% 70-79: 0.91% 80+: 4.0% All: 0.12% About 90% of the Covid-19 related deaths have been in the 70+ age group. They note: 73,000 have been inf...

35315 Statistically how common do you think something like this is? Certainly weekly somewhere in the world.  Two such events in the same geographical area (southern Sweden) within 3 weeks, however, are rare.  Such events are usually years apart. There was another event  in Japan  just one hour bef...

35311  Looking forward to getting more stats on the meteor (speed, angle, initial orbit?) if/when they're determined. My initial estimates are: entry speed: 13 km/s inclination: 22.4° radiant ra: 21:50 (327.7°) radiant dec: -37.5° Looks like a typical asteroid belt object.  It was visible for at le...

35304 Wow, would you say that fireball is brighter than -11 (the brightness of the full moon), it looks like maybe -13 to me! I haven't tried to estimate, but it's way brighter than than -13.  More like -17 or even -18, though briefly.  Meteors brightness is usually normalised to the brightness as ...
