Satelliti in orbita: la luce riflessa oscura lo Spazio

Le costellazioni di satelliti in orbita bassa rischiano di compromettere fino al 96% delle immagini dei telescopi spaziali, secondo uno studio Nasa. Il boom commerciale nello Spazio ha effetti visibili sul cosmo osservabile

hubble 35 anni — In celebration of the NASA/ESA Hubble Space Telescope’s 35 years in Earth orbit, an assortment of compelling images have been released today that were recently taken by Hubble. This stretches from the planet Mars (top left) to dramatic images of stellar birth (bottom left) and death (top right), to a magnificent neighbouring galaxy (bottom right). After over three decades of perusing the restless universe, Hubble remains a household word as the most well-recognized telescope in scientific history. [Image description: Composite shows four Hubble images in quarters. At top left is a crisp view of Mars in shades of orange, blues, and browns. At top right is planetary nebula NGC 2899, which is shaped like a single macaroni noodle, with its central torus appearing semi-transparent and blue/green, and top and bottom edges in orange. At bottom left is a tiny portion of the Rosette Nebula. Very dark gray material shaped like a V takes up the center. At bottom right is barred spiral galaxy NGC 5335 with a milky yellow center that forms a bar surrounded by multiple blue star-filled spiral that wrap up counterclockwise.]

Il cielo notturno non è più solo delle stelle: il crescente numero di satelliti orbitanti sta interferendo con le immagini raccolte dai telescopi spaziali. Uno studio della Nasa avverte che la luce riflessa dai satelliti potrebbe compromettere gran parte delle osservazioni future.
