SpaceX's new Starlink satellites produce 32 times more radio noise than their predecessors, causing concerns among astronomers about their interference with radio astronomy observations.
Radio astronomy uses supersensitive antennas to detect faint radio signals emitted by stars, black holes and other objects in the universe. Researchers working at the Low Frequency Array (LOFAR) in the Netherlands, one of the world's most sensitive radio observatories, have now found that SpaceX's growing megaconstellation of internet-beaming satellites is blinding their instruments. During a series of observations conducted in July, the researchers found that Starlink satellites crisscrossing the sky above the array appear up to 10 million times brighter than some of the most precious targets of radio astronomy research.
