• New Telescope Will Watch Entire Southern Sky in Infrared

    From Internetado@21:1/5 to All on Tue May 26 20:55:36 2020
    When it's complete, a new infrared telescope in Australia will give
    astronomers an unprecedented glimpse of the universe.

    The Dynamic Red All-Sky Monitoring Survey (DREAMS) is expected to be
    completed early next year, at which point scientists will be able to
    watch supernovae, star mergers, and other epic cosmic events in "real
    time" - giving scientists a more detailed understanding of the universe
    than ever before.

    DREAMS' camera will be able to map the entire southern sky in surveys
    that take just three days, allowing astronomers to rapidly find and
    track cosmic events.

    "By monitoring the sky continuously and rapidly, we will be able to
    search for varying and explosive phenomena," Anna Moore, Director of
    the Australian National University Institute for Space, said in a press release. "This 'real-time' astronomy, which allows us to study events
    taking place over months, weeks or days instead of millions of years,
    is a window into the great unknown."

    In this case, "real-time" doesn';t mean astronomers will see things
    like an exploding star when the actual explosion happens - that light
    still needs to travel for untold millions of years to reach Earth.
    Instead, the camera will let them gather more data of the event as its
    signal reaches Earth, sort of like upgrading from a single photograph
    to a flipbook.

    "DREAMS will allow us to 'see' the universe in an entirely new way,"
    Moore added.[...]
