    Three astronomical observatories with dome-shaped roofs are set against a star-filled night sky, with visible galaxies and nebulae.
    The Dark Energy Camera at the Cerro Tololo Inter-American Observatory captured the images of Starlink satellites.
    Scientists in cleanroom suits work on a large, round optical component, likely a lens or mirror, in a cleanroom setting.
    This 1.5-meter-diameter lens will be part of the biggest digital camera ever built, which will be installed at the Vera C. Rubin Observatory under construction in Chile. Astronomers are worried that megaconstellations of communications satellites will harm the camera’s products.
    A black-and-white image of a night sky shows numerous stars and streaks of light, indicating meteor trails.
    When Iridium launched its constellation of satellites in the late 1990s, the satellites’ streaks were sometimes visible when sunlight struck their solar arrays or antennas at night.

    These four companies are farthest along in developing megaconstellations.
