NASA's Hubble Telescope and James Webb Space Telescope: Advancing Our Understanding of the Universe

NASA's Hubble Telescope, with its decades-long exploration, has aided scientists in comprehending the universe's expansion rate. The recent launch of the James Webb Space Telescope has furthered this research, confirming that the universe is expanding faster than initially anticipated. By utilizing JWST's enhanced capabilities, studies have been conducted to measure the present expansion rate by observing pulsating stars, leading to surprising conclusions about the universe's expansion driven by mysterious dark matter and dark energy.
