    • Jimmy Carter was U.S. president and Elvis Presley was still alive in 1977, the year Voyager 1 was launched.
    • Back in 1990, Voyager 1's last picture showed Earth as nothing more than a 'Pale Blue Dot'.
    • Voyager 1 is now traversing interstellar space – here's what our solar system looks like from there.

    • The idea of growing food from CO2 dates back to NASA 50 years ago.
    • Two companies are bringing high-quality, CO2-derived protein to market.
    • CO2-based foods provide an environmentally benign way of producing the protein we need to live.

    NASA images of Mars reveal largest canyon in the solar system

    Valles Marineris on Mars is 10 times longer and three times deeper than Earth's Grand Canyon.

    • The HiRISE instrument aboard NASA's Mars Reconnaissance Orbiter captured high-resolution images of Valles Marineris.
    • Valles Marineris stretches roughly 2,500 miles across the Martian surface, and was likely formed by geologic faulting caused by volcanic activity.
    • NASA's Perseverance rover is set to land on Mars in February 2021, where it will search for signs of ancient life.

    • Researchers recently used a huge telescope in Hawaii to study primordial black holes.
    • These black holes might have formed in the early days from baby universes and may be responsible for dark matter.
    • The study also raises the possibility that our own universe may look like a black hole to outside observers.
