    The phosphine discovered in Venus' clouds may be a big deal. Here's what you need to know.

    Possible Marker Of Life Spotted On Venus

    Life on Venus would certainly be exciting, And it may be easier to get a sample return of the upper atmosphere than it would be to get a soil sample from Mars

    Could use garlic.
    Astronomers see a black hole 'spaghettify' a star in real time

    Coming too close can mean being instantly transformed into some very unpleasant pasta.
    By Eric Mack

    It's one of those astounding events that sounds like science fiction, but is just plain science. Astronomers say they were able to capture the process of a star being ripped into strips and devoured by a black hole in unprecedented detail.

    Nasa announces 'exciting' new discovery about the Moon.

    A live NASA broadcast from SOFIA (Stratospheric Observatory for Infrared Astronomy, a modified 747 aircraft).
    10/26/2020 1205pm EST.

    Water has been known to exist within the Moon's deep crater's shadows.
    It has been newly discovered that water also exists out in the open, on sun lit surfaces.
    Previously it had been thought water in the open would be lost to space.
    This discovery means much more water may exist on the moon.
    Water has many uses beyond drinking. Such as fuel, or media for experiments, etc.
    If water can be used from the moon, it would help reduce payload weight.
    Further research on why the water remains in the open, when exposed to sunshine, is planned.

    Sad follow up to Sept 2020 story about damaged Aerocebo Radio Telescope.
    .
    After Suffering Irreparable Damage, It’s Lights Out for the Arecibo Observatory’s Iconic Telescope
    By Rasha Aridi
    .
    After 57 years of gazing into the universe and helping astronomers unravel the cosmos' mysteries, the Arecibo Observatory's world-renowned telescope in Puerto Rico will be torn down, reports Alexandra Witze for Nature.

    The observatory has three towers equipped with cables that hold up the telescope's enormous, 1,000-foot reflector dish. In 2017, Hurricane Maria battered the already deteriorating telescope. This August, an auxiliary cable slipped out of its socket, inflicting a 100-foot-long gash in the dish. Three months later, a main cable connected to that same tower snapped, causing more devastating damage. Teams of engineers looked for remedies to help save the telescope, but repairs would be too risky for a construction team to safely undertake, reports Ashley Strickland for CNN.

    Given the age of the telescope, it would need more intensive maintenance in the future since the cables were weaker than originally thought. For this reason, the National Science Foundation (NSF) announced yesterday that plans to decommission the telescope were underway.
