    Does anyone wonder what out night sky might have looked like 4 billion years ago?

    Due to the things in the universe having been closer to one another, I wonder how that would have affected the gravity on earth. If you don't know, gravity is infinite, though decaying in distance. Therefore having the universe closer together, you would have more things essentially "pulling" at you, essentially reversing some of the earths gravity.

    Also, since it is earlier in the universe's life, galaxies would be less formed, and space would look more sporadic. With the whole universe being quite a bit more compact at that point, there would be no night and day, only day of varying light sources.

    Other stars would have been close enough that we would be able to see them almost like we see out sun, though quite a bit smaller in most cases.

    Lobster Nebula

    [​IMG]

    Located around 8000 ly away in the constellation of Scorpius, NGC 6357 (Lobster Nebula) is a region filled with vast clouds of gas and tendrils of dark dust. These clouds are forming stars, including massive hot stars which glow a brilliant blue-white in visible light.

    It may look like something from The Lord of the Rings, but this fiery swirl is actually a planetary nebula known as ESO 456-67. This object lies in the constellation of Sagittarius (The Archer).

    In this image, it is possible to see the various layers of material expelled by the central star. Each appears in a different hue - red, orange, yellow, and green-tinted bands of gas are visible, with clear patches of space at the heart of the nebula.

    If I've read right, our sun is actually moving thru the galaxy at something like 550k mph, still that's impressive :)

    Cigar Galaxy (M82) is ~ 12 million ly away in Ursa Major. It's a starburst galaxy meaning it has a very high rate of new star formation. The galaxy is five times brighter than entire Milky Way and produces stars 10 times faster.

    That would be the explosion itself happening much earlier. I think he just meant those images we are capturing now are 6500 years ago, which would be correct. The date of the explosion would be 6500 years before 1054 AD.

    A photo of spiral galaxies NGC 3169 and 3166. Shells, plumes, arcs of stars and even shared dust lanes are some of the features that highlight this very deep image.

    Spiral galaxy IC 5052. The blue light marks pockets of extremely hot newborn stars.

    A star formation complex in the constellation of Ophiucus containing the youngest known protostar IRAS 16293-2922B - perhaps only ~ 10 000 years old.

    I will never let this thread die.

    That's NGC 7497 galaxy

    [​IMG]

    M81 & M82 galaxies

    Galaxies in both images bathe in foreground dust. Think of it as a smudge on your window when you’re looking out at a distant mountain.

    A supernova that was witnessed by astronomer Tycho Brahe in 1572.
    The explosion spewed elements like silicon and iron into space at speeds of more than 5000 km/s. When that ejecta rammed into surrounding interstellar gas, it created a shock wave -- the equivalent of a cosmic "sonic boom". This reverse shock wave racing inward at 1000 times the speed of sound is heating the remnant and causing it to emit X-ray light.

    This image shows Stephan’s Quintet – NGC 7317, NGC 7318a, NGC 7318b and NGC 7319 – a compact group of galaxies located ~ 280 million ly away. A prominent foreground galaxy called NGC 7320 is not a member of the group.

    No problem Warlock, glad you like the pictures. Here's more new space images:

    [​IMG]

    Dragon's Head Nebula is ~ 160000 ly from Earth. This photo released today. Bigger version here: NGC 2035

    [​IMG]

    Cat's Eye Nebula (NGC 6543) is ~ 3000 ly from Earth, was formed about a thousand years ago.

    A spiral galaxy known as Topsy Turvy Galaxy (NGC 1313) located ~ 13 million ly way.

    The magenta spots in this image show two ultraluminous X-ray black holes . The black hole closer to the center of the galaxy is about 70 to 100 times that of our sun. The other black hole is probably smaller, about 30 solar masses.

    This X-ray nebula appears to look like a human hand. The ghostly shape comes courtesy of a pulsar star called PSR B1509-58 that is just 12 miles in diameter. The nebula itself is 150 ly across. This pulsar is spinning completely around almost 7 times every second and is releasing energy into its environment at a prodigious rate - presumably because it has an intense magnetic field at its surface, estimated to be 15 trillion times stronger than the Earth's magnetic field. Energy leaves mostly via neutrino emission.
    Chevalr1c and Ahhzz say thanks.
