16’2022 (2022-01-16) – Aurora

Today, I learned about:

This time of the year in the Northern hemisphere, there can appear an interesting phenomenon in the sky. It is called aurora borealis (Northern lights) and the further north you go, the bigger the chance of experiencing it. When it is winter season in the Southern hemisphere, six months from now, there is also the same phenomenon there, called aurora australis (Southern lights).

When I lived in Sweden during the 1970s and 1980s, I was lucky to have that view twice. The first was in September 1973 in Ystad on the extreme Southern coast and the second time was in Stockholm in mid-winter in 1982. And now I am informed that most parts of Sweden have had the chance to see “norrsken”, the Swedish denomination, during this weekend. The following photo was shot by my friend Arthur in Stockholm shortly after midnight on Saturday 15’2022 (2022-01-15). It was taken from Södermalm towards Strandvägen and Djurgården. Thank you, Arthur, for this Swedish (de)light!

It was one of those rare occasions when also the southern parts of Sweden could see the phenomenon of aurora borealis. Arthur Ribas took this photo from Södermalm in Stockholm, looking out over Djurgården, shortly after midnight on Saturday 22’2022 (2022-01-15).

If you want to discover what Northern lights really are, take a look in reference #1 below.

Another thing that I heard of these days is that in the USA, on 7’2022 (2022-01-07), man for the first time received a heart from a genetically altered pig. You can read more about it reference #2 below.

And today, in the morning radio news show Godmorgon, världen on Radio Sweden was discussed more about that heart transplant, if the patient’s body will accept it and not reject it, which ethical aspects we can apply to this case, if it will be possible to start using transplanted organs from animals, etc. If you understand Swedish, I urge you to listen to the interesting conversation in reference #3.

That’s what I learned in school today!
