The James Webb Telescope provides new data on the expansion rate of the universe.
Key findings include:
The telescope's advanced infrared capabilities allow for more precise measurements of cosmic distances.
It helps scientists to measure the Hubble Constant at 70.4 kilometers per second per megaparsec, with a 3% margin of error.
This measurement aligns more closely with data from the cosmic microwave background (CMB), which is 67.4 ± 0.7%.
The Webb telescope's high resolution and sensitivity enable observations of fainter stars at greater distances.
This reduces uncertainties in distance measurements due to cosmic dust and variations in star brightness.
Scientists plan to use the Webb Telescope to observe the Coma cluster for direct Hubble Constant measurements.
