    It's amazing that Herschel Space Observatory managed to get such details which Spitzer Space Telescope and Hubble couldn't.
    There's enough dust to make around 30 000 - 40 000 Earths. :)
    We can see these filaments of dust in the far-infrared region of the electromagnetic spectrum (right part of the image).

    Looks beautiful!

    6500 light years away... so what we are seeing has already happened 6500 years ago right?

    Ancient Chinese saw that explosion in 1054 AD :) It was so bright that you could easily read a book in the nighttime :D

    So let's do some math: distance is 6500 ly and Chinese saw that in 1054 AD. It means it happened much much earlier.

    Correct.


    Or so I thought. Is there a reason that the light from the nebula would travel faster than light? or has the distance between us and the crab nebula expanded between now and 1054 AD?

    They said that it was seen in 1054 and lasted for two years. What we see now is all the radiation that left after the explosion.

    So I think actual explosion happened 6500 (distance) + 1054 (when it was observed) = 7554 years ago :confused: I might be wrong


    Lol here it says that Crab Nebula is 6000 ly away, gosh :rolleyes:

    Some other goodness (brand new images) I wanna post here:



    [​IMG]

    NGC 5189 is a planetary nebula that lies 1800 ly away in the southern constellation Musca. The gorgeous image above shows the glowing streamers of oxygen, sulfur and hydrogen that are being blown far into space from the hot star HD 117622 at its heart.

    Ok now some other crazy stuff :D

    [​IMG]

    Cygnus Loop, the gaseous remains of a supernova that occurred 5000-10000 years ago, spans an area nearly 45 times the width of the full Moon in the sky. First noted in 1784 by William Herschel. This remnant is located 1500 ly away in the constellation Cygnus.

    In the image, hydrogen alpha, sulphur, and oxygen ions correspond to the red, green, and blue color values, respectively.

    Picture above is a preview. Actual image is One of the Largest Astronomical Images Ever Made so if you've got balls click here. It's full-size 1.7 GB TIFF image (600 megapixels) ahahaha. Or you can see smaller versions here

    If the distance to the nebula is 6500 ly, then the blast actually took place 6500+958=7458 years ago realtime. And it was observed on Earth in 1054 (958 years ago).

    i was just looking at the crab nebula last night with my mew telescope, of course it was not a brilient at this but still i LOVED it along with jupiter and a few double stars that i had a good look at.

    I have not done this sense my early teens, and i was texting my gf at midnight telling her every little thing i saw (she apreciated been woken up to hear all that)

    Fair enough.

    That's sweet.

    Yeah and now more :D


    Here we have new image of Zeta Ophiuchi (bright blue star at center)

    Death of one star sent other star rushing through space with enormous speed... would you ever imagine that ... :D

    Crrrrrrrowd of stars :D NGC 6388

    [​IMG]

    This image from the NASA/ESA Hubble Space Telescope shows NGC 6388, a dynamically middle-aged globular cluster in the Milky Way. While the cluster formed in the distant past (like all globular clusters, it is over 10 billion years old), a study of the distribution of bright blue stars within the cluster shows that it has aged at a moderate speed, and its heaviest stars are in the process of migrating to the centre.

    Another cool pic taken by Hubble. A baby star.

    And here's video:



    Groovy.

    people alive in 1054 AD aren't exactly ancient.

    Thank you for finding the great ones Drone!!! It takes time to sift through all pictures of the heavens to find the best ones like these!

    A bunch of pics for today. No worries, only brand new hot and sexy images:

    [​IMG]

    The heart of the barred spiral galaxy NGC 1097

    [​IMG]

    The globular cluster 47 Tucanae

    [​IMG]

    Spiral galaxy M101 (the Pinwheel Galaxy)

    [​IMG]

    An archetypal dwarf galaxy NGC 5477

    http://cdn.physorg.com/newman/gfx/news/hires/2013/galexreveals.jpg

    And finally ... giant barred spiral galaxy NGC 6872. It's the largest known spiral galaxy.

    The spiral is ~ 522,000 ly across from the tip of one outstretched arm to the tip of the other, which makes it about five times the size of the Milky Way.

    IC 4970, the small disk galaxy interacting with NGC 6872, is located above the spiral's central region.

    Brand new image of Lupus 3 (a dark cloud in the constellation of Scorpius, 600 ly from Earth)

    Darkness creates the light. How fascinating.

    Toddler stars, that's cute.

    New image of clouds of cosmic dust in the region of Orion.

    [​IMG]

    The image shows the region around the reflection nebula NGC 1999 in visible light. While these dense interstellar clouds seem dark and obscured in visible-light observations, APEX’s LABOCA camera can detect the heat glow of the dust and reveal the hiding places where new stars are being formed.

    M106 is a spiral galaxy, located a little over 20 million ly away. At its heart, as in most spiral galaxies, is an active supermassive black hole.

    [​IMG]

    A new sweeping image from NASA's WISE showing the tangle of clouds and stars that lie in Orion's Sword.

    Image of NGC 1973, the Running Man Nebula, located roughly 1500 ly from Earth in the constellation of Orion.
