Skies on Friday

 The view of earth as darkness falls...from the space station.



A faked image from 2021, Where Night meets Day.


M. C. Escher was interested in where sky meets water.


A canoe in the Sandwich Islands by Bowers Masked. More water, but a sail to catch the wind too.

Explanation: Do we dare believe our eyes? When we look at images of space, we often wonder whether they are "real", and just as often the best answer varies. In this case, the scene appears much as our eyes would see it, because it was obtained using RGB (Red, Green, Blue) filters like the cone cells in our eyes, except collecting light for 19 hours, not a fraction of a second. The featured image was captured over six nights, using a 24-inch diameter telescope in the Sierra Nevada Mountains, in California, USA. The bright spiral galaxy at the center (NGC 7497) looks like it is being grasped by an eerie tendril of a space ghost, and therein lies the trick. The galaxy is actually 59 million light years away, while the nebulosity is MBM 54, less than one thousand light years away, making it one of the nearest cool clouds of gas and dust -- galactic cirrus -- within our own Milky Way Galaxy. Both are in the constellation of Pegasus, which can be seen high overhead from northern latitudes in the autumn.

See the Pillars of Creation like never before!
First made famous by NASA's Hubble Space Telescope in 1995, NASA's James Webb Space Telescope revisited this iconic part of the Eagle Nebula, revealing new details and hidden stars: https://go.nasa.gov/3ySxmYS

If you do Facebook, the Astronomy Picture of the Day is often quite fun to see!
