Messier 97 (top) and Messier 108 (bottom) in Ursa Major are two celestial objects that appear to be close to each other but in reality are separated by an immense distance in space.
M97, known as the Owl Nebula, is a planetary nebula located inside our own galaxy at about 2,500 light-years away and has a diameter of about 2 light years. It was discovered by Pierre Méchain in 1781 and it was included in the famous catalogue of Charles Messier as entry 97. Two prominent dark spots inside the nebula give the appearance of an owl’s face.
A planetary nebula is formed by the expanding shell of gases blown off by a dying star at the last stages of its life. The expanding shell is heated by the radiation of the central star (a very faint 16th magnitude star in this case) and it glows mostly in green light of oxygen atoms. The nebula will completely disperse into space over the next several thousand years, while the central star will cool and fade away over the next several billion years.
The estimated age of the Owl Nebula is about 6,000 to 8,000 years.
Galaxy M108, the Surfboard Galaxy, is harder to see in a telescope than M97, because its light is spread out over a larger area. It happens to lie near the same line of sight as M97 but is located at about 45 million light-years away. M108 is an edge-on spiral galaxy, heavily obscured by dust. It was also discovered by Méchain.

I gaze through the wormhole, fixed in space, experiencing the thrilling speed of of the citrus grove as it rushes past, propelled by the earth's movement, spinning and circling the sun, an ancient, frenetic dance set in motion long, long ago.
I close the wormhole and return to reading today's copy of the New York Times. Ah, a revival of Pippin opens this weekend. I must go.

Thank you to everyone who pauses long enough to look at my photo. All comments and Faves are very much appreciated
Standing by the sea, I look out into infinity.
My gaze sweeps from left to right, and I can see almost 180 degrees. With my own eyes, I can observe the curvature of the horizon. I’ve come face to face with the planet.
It does something to you, to see it with your own eyes, this incomprehensible scale of the ocean. It's liberating. You let go of left-brain knowledge and lose yourself in awe.
Our ancient ancestors all the way back to the first animals have been seeing oceans just like this, and if there are other living worlds out there, they may have similar watery expanses.
Standing by the sea, I feel the oneness of it all. I feel connected to eternity.
Absolutely thrilled to photograph Venus, Jupiter and Mars this morning! We had hazy cloud but could still make out Mars with the naked eye ;0)
And wonderful to have this photograph featured amongst so many fantastic captured from around the world!

"Planetary by My Chrmical Romance"
There might be something outside your window
But you'll just never know
There could be something right past the turnpike gates
But you'll just never know
If my velocity starts to make you sweat
Then just don't let go
And if their heaven ain't got a vacancy
Then we just, then we just, then we just
Then we just get up and go!

From Left edge tiny Comet Catalina, Venus, Mars, Moon Jupiter top Right. If you zoom in 100% there is tiny star on the left of Venus that is Comet Catalina
taken from my backyard in April/May 2021 telescope session , from two hundreds sub frames I choose 90 the best x 120 seconds exposure time each for stacking and processing in PixInsight .Thanks for looking :) I used my home build Newtonian telescope with QHY268C camera and Optolong UV/IR Cut filter . thanks for looking .
