I still think when we look through a powerful telescope, we're seeing WHAT IS THERE AT THAT MOMENT.
Just a belief I have personally.
Does a photon of light travel "forever" in a straight line? Light can be bent by the gravitational force of another object (such as a black hole)
Why are stars seen as pinpoint spots of light? Distance determines the size of the pinpoint and none of them are close other than our own sun.
Shouldn't the star's light be spread out in all directions making the light diffused? If space was as filthy dirty as the air in downtown LA, yes, but it's not. For the most part

Those questions touch on what's known as the "Night Sky Paradox"
https://en.wikipedia.org/wiki/Olbers'_paradox
It's actually pretty fundamental to current thinking on the expanding nature of the universe.
As to what photons do, they will travel forever at the speed of light (in whatever medium they're traveling through) until and unless something happens to them. Stuff happens to photons all the time.
The inviolable nature of c (the speed of light "in a vacuum") leads to some interesting effects all by itself. The speed of light is an upper limit, but it depends on the medium through which light passes (which is also true of the speed of sound... but I digress). The speed of light in a vacuum is different than the speed of light through glass, or water.
One very real consequence of this is the blue light seen in water tanks in certain nuclear reactors. This
glow is called Cherenkov Radiation and is a direct result of what happens when something traveling "at the speed of light" in one medium crosses a transition into another medium in which the
speed of light is lower. Something's gotta give! And something does -- the excess velocity 'bleeds off' in the form of energy -- in the case of Cherenkov Radiation, in the form of "blue light" photons.

We are. However, 'THAT MOMENT' occurred at some point in our past.

Viewed from the perspective of a light beam/photon particle, there is no time.
Has to be that way, because the speed of light is an "inviolable" constant. For example, suppose you were on a train going 75% of the speed of light in one direction. Another train moving at 75% of the speed of light passes you going the other direction. What's the speed of the other train from your observation point? 150% of the speed of light, right? Wrong-o-rama, since it can't be.
No problem -- as long as the rate of time passage decreases with increasing velocity.
At the speed of light, "It's always five o'clock" is absolutely true, not just "somewhere".
This effect (time moving slower as the speed of light is approached), known as time dilation, was nicely explained by astrophysicist Dr. Brian May, albeit in his side hustle.

For those that are interested....Mark your calendar for June 24th @4:20am. For the first time in 100 years, you may get a glimpse of the unusual sky occurrence on that morning when all five planets (Mercury, Venus, Mars, Jupiter, and Saturn) and the moon will be visibly lined up simultaneously.
https://www.chaosmosnews.net/2022/06/05/dont-miss-rare-alignments-of-5-planets-for-first-time-in-100-years/?fbclid=IwAR3j1VjGwjsHxdZHgfsHVu1DP6cQV17M5UmZJXvsKmszga5tay747uZ6vZ4
So, the very day I posted about ^^^this^^^, apparently NASA took a shot of the aligned planets from Chile.
The planet Mercury has wandered about as far from the Sun as it ever gets in planet Earth's sky. Near the eastern horizon just before sunrise it stands over distant Andes mountain peaks in this predawn snapshot from the valley of Rio Hurtado in Chile.
June's other morning planets are arrayed above it, as all the naked-eye planets of the Solar System stretch in a line along the ecliptic in the single wide-field view. Tilted toward the north, the Solar System's ecliptic plane arcs steeply through southern hemisphere skies. Northern hemisphere early morning risers will see the lineup of planets along the ecliptic at a shallower angle tilting toward the south. From both hemispheres June's beautiful morning planetary display finds the visible planets in order of their increasing distance from the Sun.

Here is another thing that fascinates me. Aurora Vortex's. These are sometimes visualized by lightning type flashes (although I have personally never seen any video to support this...).
Even cooler, is what can happen ABOVE them.....check this out....

Here's another date that we should be keeping an eye on. July 12, 2022 - NASA is scheduled to release the first images taken by the James Webb Space Telescope. Testing and calibration has been completed, target camera temps have been achieved (minus 449°F – just 11°F above absolute zero) and the first images look to be very promising.
https://theconversation.com/the-james-webb-space-telescope-is-finally-ready-to-do-science-and-its-seeing-the-universe-more-clearly-than-even-its-own-engineers-hoped-for-184989?fbclid=IwAR2C60Wqb6SmCnOQ1PuqDq5IRSpWVgzBXGW16YToTel76I6zc1My_RDtbBk
The MIRI camera, image on the right (below), allows astronomers to see through dust clouds with incredible sharpness compared with previous telescopes like the the Spitzer Space Telescope, which produced the image on the left.
The Webb will be able to detect galaxies completely hidden by dust and undetectable by telescopes like Hubble. Exciting times! I don't know about you but I can't wait for the first images to start rolling in.

Astronomers Have Captured the Most Detailed Image Yet of a Monster Galaxy 12.4 Billion Light Years Away.

The previous captures we had...
From the article wrote:This ‘monster galaxy’ is approximately 12 billion light-years from Earth and generates new stars 1,000 times faster than our own Milky Way galaxy. Scientists used Chile’s $1.5 billion ALMA Observatory to capture views of the galaxy with a resolution ten times higher than any previous attempt, dubbed ‘COSMOS-AzTEC-1.’

Anybody know how to tow this? Asteroid worth up to $700 quintillion mapped in highest resolution yet.
The 16 Psyche asteroid is scheduled to be visited by a NASA probe that will launch later in 2022. The spacecraft will visit the asteroid belt occupying the region between Mars and Jupiter, comprising remnants from the solar system's formation. One such remnant is the 16 Psyche asteroid, thought to be the core of an ancient planet, which contains a large number of valuable metals.

For some reason, out of all of the incredible space photos, that photo has got to be either my all time favorite or at the very least, one of the top 5. This is one of those pictures that got lost in the vast abyss of the picture thread. Thanks man!

Our own moon. Without the moon, we would have far less (if any) tectonic plate shift, tides would go to a highly argued 50% height to 75% drop in height, we wouldn't have any seasons due to no stabilization of Earth tilt (basically, we would simply wobble erratically), over time within our days would be altered (we used to have 4 hour days billions of years ago) and the loss of the "flexing" of the Earth could cause some rather strange and unknown effects with earthquake and volcanic activity.
It is thought that without the moon? We wouldn't be here right now. None of us.

Nothin' special -- but I was out photographing lightning bugs again last night. The night sky was fairly pretty (given that it's early summer), so I snapped a few photos.
