“Good evening all. A little bit of a surprise for you tonight. As you may, or may not, know. Mr. Walrus is away on vacation so lots of things are on hiatus including the FCF. But there is still something going on. We wanted to ask all you loyal posters of IMAO for your opinion. What do you like best about IMAO? What would you change? What might we try? What’s the airspeed velocity of an unladen Swallow? Please take the time and be honest, nothing will happen to you. Well, I do hear that you might have The Emu pay you a visit for a little “yakking”. How bad can that be? So have at it and Mr. Walrus will return later in May.”

Straight Line of the Day: Why Is Neptune Cooling Down?

Neptune Is Cooling Down and Scientists Don’t Know Why
Space.com | Tereza Pultarova

Two decades worth of observations revealed unexpected cooling of the solar system’s most distant planet, Neptune, amid its astronomical summer.

Neptune is orbiting 30 times farther away from the sun than Earth with one year lasting 165 Earth years. The ice giant’s seasons, too, last much longer than those on Earth ― more than 40 Earth-years each.

As the planet moved into its southern summer over the past two decades, astronomers observed its average global temperatures plummet by a staggering 14 degrees Fahrenheit (8 degrees Celsius).

The observed cooling, however, wasn’t uniform, the researchers said in the statement.

Measurements of Neptune’s stratosphere, the second lowest layer of the planet’s atmosphere, revealed a warming trend above Neptune’s south pole. This data set, which only contained data from a two-year period between 2018 and 2020, revealed a speedy warming of about 20 degrees F (11 degrees C). The scientists said that such polar warming has never been observed on Neptune before.
