Through the lens of the Hubble and James Webb Space Telescopes, scientists are zeroing in on the Hubble Constant, a vital measure that indicates the universe’s expansion rate.
Recent studies, especially those involving the JWST, have provided more precise measurements, crucial for understanding the universe’s broader properties.
Understanding the Hubble Constant In recent years, we’ve witnessed incredible advancements in our understanding of the universe, thanks to the Hubble Space Telescope (HST) and its successor, the James Webb Space Telescope (JWST). Both telescopes have revolutionized astronomy, uncovering stunning discoveries.
Among their shared focus has been refining the Hubble Constant, a key measurement that links the speed at which distant galaxies are moving away with their distances. A recent study confirms that JWST has validated earlier findings from HST, providing more precision in this critical measurement. READ MORE...
For decades, scientists have been grappling with what is considered to be the most fundamental question about the cosmos: How fast is our universe expanding?
The rate of expansion influences everything from how galaxies form to how they might one day drift apart.
Determining the expansion rate of the universe, a number called the “Hubble constant,” shapes our entire understanding of the cosmos, its age, and its ultimate fate.
“Hubble tension” expansion conundrum Unfortunately, though many brilliant minds have dedicated their lives to finding the answer to this riddle, all who have tried thus far have failed, running repeatedly into a brick wall that has come to be known as the “Hubble tension.”
Adam Riess, a physicist at Johns Hopkins University in Baltimore, has been at the forefront of this debate. “With measurement errors negated, what remains is the real and exciting possibility that we have misunderstood the universe,” Riess admitted. READ MORE...
