NASA planning to send an artificial 'star' to space. Here's all about the mission
NASA is planning to send an artificial star into space to help scientists solve some of the universe's biggest mysteries.
Led by researchers at George Mason University, this $19.5 million mission will allow scientists to calibrate telescopes and more accurately measure the brightness of stars, from those nearby to distant supernova explosions in far-off galaxies.
The mission aims to unravel key astrophysical mysteries, including the speed and acceleration of the universe's expansion.
Named after late astronomer Arlo Landolt, known for his influential stellar brightness catalogs from the 1970s to the 1990s, the mission will launch an artificial light source into space by 2029. With a known photon emission rate, this artificial star will be observed alongside real stars, allowing researchers to create new stellar brightness catalogs.
The satellite, equipped with eight lasers, will shine on ground-based optical telescopes to calibrate them for more precise observations. While invisible to the naked eye, the artificial star can be seen through a home telescope.
