    Here in Nili Fossae, we see layered bedrock as horizontal striations in the light toned sediments in the floor of a canyon near Syrtis Major. (Note: illumination is from the top of the picture) The ancient layered rocks appear in pale whitish and bluish tones. They are partially covered by much younger ripples made up of dust and other wind blown sediments. The rock of the nearby canyon wall is severely fractured and appears to have shed sand and rocks and boulders onto the floor. This canyon did not form by fluvial erosion: it is part of a system of faults that formed a series of graben like this one, but water probably flowed through Nili Fossae in the distant past.

    Although NASA’s Hubble Space Telescope has taken many breathtaking images of the universe, one snapshot stands out from the rest: the iconic view of the so-called “Pillars of Creation.” The jaw-dropping photo, taken in 1995, revealed never-before-seen details of three giant columns of cold gas bathed in the scorching ultraviolet light from a cluster of young, massive stars in a small region of the Eagle Nebula, or M16.

    And now, in celebration of its upcoming 25th anniversary in April, Hubble has revisited the famous pillars, providing astronomers with a sharper and wider view.

    Gorgeous.

    Did you enjoy the Sandra Bullock movie?

    This might seem like a stupid question or something basic, but I'll ask it anyways at the risk of being laughed at. Is the color in the pictures/images and in the NASA YouTube video a true representation of colors in space? Are they filtered or are they approximations of what the human eye would see or really accurate? What is 4K?

    I believe they are colored in using a process for accuracy. I forgot how it works right now.
    4K is better than HDTV. Meaning it has 4000 pixels a line rather than 1080.

    I believe NASA has a process they use to color it in.
    4K is 4 times better then normal 1080 HDTV.

    NASA has a process for accurately coloring the photos. It's interesting if you have time to look it up.
    4K is higher resolution HDTV by 4 times as much, has to do with number of pixels per line.

    I don't have anything substantial to add to this conversation, other than I am enjoying learning new things and this is a cool topic. The pictures on the thread are fantastic and learning about the different sites to check out the Stars are cool. The main reason that I popped in was because it was cool to see the character "Inky" next to the word space. Random and nothing to do with space. More pictures of space and stars please. They are stunning!

    Here's Pyramid and Colonial Peaks from the Diablo Lake Overlook.

    Milky Way on the right, Mt Shuksan on the left. Ann Lake was about a five mile hike, and the lights are other people camping for the night.

    This one is my favorite. Moonset over the Pasayten Wilderness. The bright red on the horizon is light pollution from Vancouver BC and from Seattle.

    Armstrong Mountain, Horseshoe Basin, in the eastern Pasayten. This was a ten mile hike. I shot this during the Perseid meteor shower and was disappointed not to get any of them.

    Aurora. These were barely visible, and just gray. But the camera is more sensitive than the eye.

    @NorthCascades you're pictures are phenomenal

    There aren't that many people doing astro landscapes. It's a lot of fun. Challenging and frustrating, and it involves a lot of standing around in the cold for hours, but it's fun. I never expect any of these to actually work out, so I'm always delighted when I get something pretty.

    It's ok! Less gravity = weigh less

    But less gravity does not equal less mass or volume

    Sorry! Lol.
