OUR Hubble Space Telescope is currently on a mission to estimate the expansion of the universe, so a lot of data has been collected and some of these results have been made public. The collected data led the US space agency NASA indicate that “something strange” is happening to the universe.

This is due to a discrepancy in the rate of expansion of the universe around us and in observations made after the Big Bang.

These new discoveries indicate that the universe is not expanding at the same rate as scientists expected, but is instead expanding at a faster rate than expected.

Thus, scientists are now striving to understand this new phenomenon and be able to measure this expansion rate, because it is important to understand what conditions cause the Universe to behave in this way.

Expansion and James Webb Telescope

The study of the expansion of the universe is not something new, in fact it began several decades ago, more precisely in 1920, when Edwin P. Hubble and Georges Lemaitre suggested that galaxies outside ours were not stationary, that is, they were moving away from us.

Hubble, will even add that the more this galaxy is removed from the planet Earth, the faster it will move away. However, with the Hubble data available today, instead of 67.5 (plus or minus 0.5) kilometers per second per megaparsec (astronomical unit of distance, equivalent to 1 million parsecs), observations point to 73 (plus or minus 1) kilometers per second per megaparsec, suggesting a much higher speed than the expected model.

This strange phenomenon is being studied by scientists in conjunction with space and time “indicative markets” that can be used to track the expansion rate of the universe as these distant galaxies continue to move away from us.

“The Webb Space Telescope will expand on Hubble’s work by showing these cosmic landmarks at greater distances or with finer resolution than Hubble can see,” NASA said.

OUR NASA also reported that he has calibrated over 40 markers since launch Hubble telescope in 1990. And with the launch James Webb Space TelescopeScientists hope that with the new data collected, they will be able to gain a deeper understanding of this subject.
