Washington, November 6 (IANS) The Space Telescope Science Institute (STScI) in the United States has launched a new initiative with NASA’s Hubble Observatory to examine more than 300 nearby stars.
Called ULLYSES, short for UV Legacy Library of Young Stars as Essential Standards, it is Hubble’s largest observation program ever in terms of the time Hubble will devote to it, NASA said Thursday.
“One of the main goals of ULLYSES is to form a comprehensive reference sample that can be used to create spectral libraries that capture the diversity of stars, ensuring a legacy dataset for a wide range of astrophysical topics,” program leader Julia Roman -Duval of STScI said in a statement.
“ULLYSES is expected to have a lasting impact on the future research of astronomers around the world.”
Hubble sits above Earth’s atmosphere, which filters out most of the UV radiation from space before it reaches Earth’s telescopes.
Hubble’s ultraviolet sensitivity makes it the only observatory up to the task because young stars radiate much of their energy into the UVs as they grow chaotically in jumps and feed on falling gas and dust.
The goal of the program is to provide astronomers with a much better understanding of star birth and how it relates to everything from planets to the formation and evolution of galaxies.
Astronomers want to learn how young, low-mass stars affect the evolution and composition of the planets that form around them.
