ESA’s Euclid telescope will study how matter and dark energy form the universe.
REPUBLIKA.CO.ID, JAKARTA—Rocket SpaceX Falcon 9 carrying a telescope Euclid belonging to the European Space Agency (ESA) successfully lifted off from Cape Canaveral, Florida, last week. The telescope will study how matter and dark energy form the universe.
Euclid is equipped with a number of powerful tools. First, there’s the 600-megapixel camera that astronomers will use to image a third of the night sky over the next six years.
Second, Euclid was equipped with a near-infrared spectrometer and photometer to measure the galaxy’s redshift. In conjunction with data from ground observatories, the information will help scientists estimate the distances between different galaxies.
Euclid’s flight brings hope for physicists to determine whether Albert Einstein’s general theory of relativity works differently on cosmic scales. It’s possible that spacecraft could revolutionize our understanding of physics and offer a glimpse into the ultimate fate of the universe.
“If we are to understand the universe in which we live, we need to unravel the nature of dark matter and dark energy and understand the role they play in shaping our cosmos. To answer this fundamental question, Euclid will provide the most detailed map of the extra-galactic sky,” said ESA’s Director of Science, Carole Mundell. EngadgetMonday (3/7/2023).
Euclid would travel roughly one million miles to the solar system’s second Lagrange point. That is the same area of space where the James Webb Space Telescope has been operating for the past year.
It took Euclid about a month to travel there and another three for ESA to test the spacecraft’s instruments before Euclid can begin sending data back to Earth.
