    A lot of food for thought here.
    "Rather than being out on its own, the Earth is at the centre of a giant, 1,000-light-year-wide bubble, created by at least 15 supernova explosions, a new study has found.
    There are thousands of young stars at the edge of this bubble, according to astrophysicists from the Space Telescope Science Institute in Baltimore, Maryland.
    Working with experts from Harvard and Smithsonian, the team reconstructed the evolutionary history of the galactic neighbourhood over 14 million years.
    In the 1970s astronomers discovered Earth was in a cosmic void, after realising no stars had formed in 14 million years, with all stars inside this 'bubble' emerging either before it formed, or passing through on their orbit of the galactic centre.
    The new study found that multiple supernova explosions 14 million years ago blasted materials needed for star formation to the edge of a huge area of space, creating a 'superbubble' that is surrounded by a frenzy of star bursts, but with none inside.
    The team likened the discovery to a Milky Way that resembles a 'hole-y Swiss cheese', where the holes in the cheese are blasted out by supernova, allowing new starts to form in the cheese, around the holes.
    'This is really an origin story; for the first time we can explain how all nearby star formation began,' said astronomer and co-author Catherine Zucker."

    "Astronomers think they've found an 'exomoon' – a moon that exists outside our own solar system – based on data from NASA's Kepler space telescope.
    In a new paper, the experts report the discovery of a mysterious body that is almost three times the size of Earth, which they think is an exomoon.
    It's more than 20,500 miles in diameter, compared with Earth's diameter of 7,900 miles.
    It's orbiting a Jupiter-sized planet called Kepler 1708b in another solar system, 5,500 light-years away from Earth.
    The existence of any exomoon is yet to be officially confirmed, although the first potential candidate was identified four years ago.
    Since exomoons cannot be imaged directly, their presence is inferred when they pass in front of a star, momentarily dimming the star's light."

    I told my hillbilly/fundamentalist/moronic cousins that the JWST was actually going to spy on people like them because "we" are afraid Trump won't be able to reverse the 2020 election. There was a lot of "I told ya so!" in my inbox.

    Never mind it's over 800,000 miles away and still going. Oh ,and pointing the wrong way.

    Its fully deployed and 71000m away from orbit approx 1 million miles out...The Moon is only 239000 miles away from Earth...The Sun is 94 Million miles from Earth...(And still bloody hot here in Darwin).

    Where Is Webb? NASA/Webb

    An interesting side line:
    "Wavefront sensing and control was developed to sense and correct any errors in the telescope's optics. This is essential to making the 18 mirror segments work together as a single giant mirror."

    A spin off of this:
    The work performed on the telescope optics resulted in a NASA tech spinoff for diagnosing eye conditions and accurate mapping of the eye. This spinoff supports research in cataracts, keratoconus (an eye condition that causes reduced vision), and eye movement - and improvements in the LASIK procedure.
