    Just in case you missed it, this short video (1 minute only) showcases the ability of the James Webb telescope in a totally awesome fashion.
    The video was released 2 days ago, if you can, watch it on the biggest screen you have available, preferably a large television.
    Make sure to set the video quality on youtube to the highest your tv will handle, the higher the better (it's available in 4k), and be utterly amazed.
    The nebula the video concentrates on is 2000 lightyears away, so the light in the final picture traveled 2000 years to reach us. In comparison, light needs just one second to travel from the moon to earth, or 8 minutes to reach us from our own sun.

    That 8 minutes is 93 million miles and also known as one astronomical unit or AU.

    Quite coincidentally, the number of inches in a mile, 63,360, is almost exactly the same as the number of AU in one light year, 63,000.

    So how far has any man made object traveled from earth? The Voyager probes left mother earth 45 years ago in 1977. Voyager 1 is only 157 AU away. Voyager 2 is only 130 AU away.

    I watched a few videos on the James Webb telescope. Love space and the Science of it all. And firmly believe there is no such thing as an end to space.
