Yes, it is a cold, rainy morning this morning. Quite a difference a day makes. Yesterday it was warm and dry and got up in the 70's. I guess the warmest part of today happened just after midnight last night. We might think that it feels really cold sometimes and sometimes I hear a lot of complaints about the cold spells. Well, let me tell you, you ain't felt real cold.
I am going to list some of the coldest places in the universe, that we know of and have actually measured. Let me start with Triton, the largest moon of the planet Neptune. Voyager 2 recorded -391 back in 1989. Let's go out a little further to Pluto where it gets to -393 degrees.
Not cold enough for you yet? In 2011 the temperature on Eris (which is now classified as a minor planet) got down to a -393 degrees Fahrenheit. But even closer to home, the craters near our moon's pole was measured at a -415 F. Now that is getting rather chilly, isn't it? But wait!! There is a place that is 30 degrees cooler than that. (Cooler? Not quite the right adjective) Have you guessed where it is? No, it isn't a witch's . . . just colder. It is intersteller space where it has been measured at a very bone chilling -455 degrees Fahrenheit. Since absolute zero is -459.67 degrees, I would say that intersteller space is almost as cold as it can get. Oh yes, some may ask why temperature can't go below absolute zero. Well, it is where a substance has no thermal energy and where particles stop moving.
Now, I bet this little cold spell that moved in doesn't feel all that bad, does it? You all keep warm and happy, you hear?
