NASA Astronomy Picture of the Day:

Why are the regions above sunspots so hot? Sunspots themselves are a bit cooler than the surrounding solar surface because the magnetic fields that create them reduce convective heating. It is therefore unusual that regions overhead -- even much higher up in the Sun's corona -- can be hundreds of times hotter. To help find the cause, NASA directed the Earth-orbiting Nuclear Spectroscopic Telescope Array (NuSTAR) satellite to point its very sensitive X-ray telescope at the Sun. Featured here is the Sun in ultraviolet light, shown in a red hue as taken by the orbiting Solar Dynamics Observatory (SDO). Superimposed in false-colored green and blue is emission above sunspots detected by NuSTAR in different bands of high-energy X-rays, highlighting regions of extremely high temperature. Clues about the Sun's atmospheric heating mechanisms come from NuSTAR images like this and shed light on solar nanoflares and microflares as brief bursts of energy that may drive the unusual heating.

Is this now the time
to flee to the sky,
on gossamer wings?
Important to do,
much harder to say,
when changes are made,
to benefit all,
in the care to be received.
Why do I feel,
I have failed my vows
and deserted my wife.
"It's all for the better",
someone will state.
I know this is true.
It had to happen,
of this, there's no doubt.
Why am I not ecstatic,
being by her side,
in a memory unit,
I'm just along for the ride.

NASA Astronomy Picture of the Day:

Why is the Moon on top of this building? Planning. It took the astrophotographer careful planning -- including figuring out exactly where to place the camera and exactly when to take the shot -- to create this striking superposition. The single image featured was taken in the early morning hours of November 19, near the peak of the partial lunar eclipse that was occurring as the Moon passed through the Earth's shadow. At this time, almost the entire Moon -- 99.1 percent of its area -- was in the darkest part of the Earth's shadow. The building is the Gran Torre Santiago building in Chile, the tallest building in South America. Although the entire eclipse lasted an impressive six hours, this image had to be taken within just a few seconds to get the alignment right -- the Earth's rotation soon moved the building out of alignment. The next Earth-Moon eclipse will be a total eclipse of the Sun that will occur on December 4 -- but only be visible from the bottom of our world.

Frederick Douglass (1817 - 1895) - Born Frederick Augustus Washington Bailey. He was an American abolitionist, social reformer, writer, orator and statesman. He escape from slavery in Maryland and became a national leader of the abolitionist movement. Known for his oratory and antislavery writings. He was described by abolitionists in his time as a living counterexample to slaveholders' arguments that slaves lacked the intellectual capacity to function as independent American citizens.
Douglass wrote three autobiographies, describing his experiences as a slave and later times of his life. Douglass also actively supported women's suffrage, and held several public offices.

NASA Astronomy Picture of the Day:

Here comes Comet Leonard. Comet C/2021 A1 (Leonard) was discovered as a faint smudge in January 2021 when it was out past Mars -- but its orbit will take the giant shedding ice-ball into the inner Solar System, passing near both Earth and Venus in December before it swoops around the Sun in early January 2022. Although comets are notoriously hard to predict, some estimations have Comet Leonard brightening to become visible to the unaided eye in December. Comet Leonard was captured just over a week ago already sporting a green-tinged coma and an extended dust tail. The featured picture was composed from 62 images taken through a moderate-sized telescope -- one set of exposures tracking the comet, while another set tracking the background stars. The exposures were taken from the dark skies above the Eastern Sierras (Mountains), near June Lake in California, USA. Soon after passing near the Earth in mid-December, the comet will shift from northern to southern skies. APOD Editor (RJN) Online Monday: NASA's Best Space Images (& Videos)
