By Chris Skeldon The Hubble Space Telescope is one of the most powerful tools the world knows when it comes to interstellar measurements. With more than a billion images of strange and intriguing phenomena happening around the universe at your fingertips, Hubble is currently working on a large-scale task — determining how fast our universe is expanding.
The new findings now indicate that the universe is not expanding at a uniform rate. NASA suggested that “something strange” is happening in the universe due to the discrepancy in the rate of expansion of the universe around us and observations made after the Big Bang.
The study of how and how fast the universe expanded began decades ago in the 1920s, when Edwin B. Hubble found that these galaxies were moving at an increasingly irregular rate. The farther away the galaxy is from Earth, the faster it is moving away.
Since then, scientists have tried to understand the phenomenon and measure the rate of this expansion. However, with Hubble data now available, this expansion appears to be faster than models had expected. Instead of 67.5 (plus or minus 0.5) kilometers per second per megaparsec, the notes note 73 (plus or minus 1) kilometers per second per megaparsec.
Scientists are currently studying the strange phenomenon of a range of time and space “tilt markets”. These can be used to track the expansion rate of the universe as distant galaxies continue to move away from us. NASA said Hubble has calibrated more than 40 miles of markers since the telescope was launched in 1990.
As the new data begins a new assessment of our understanding of the expansion of the universe, scientists are now waiting for data from the new James Webb Space Telescope that will allow a deeper look into matter. “The Webb Space Telescope will expand Hubble’s work by showing signs of cosmic features at greater distances or at a higher resolution than Hubble can see,” NASA said.
