NASA: Strange things are happening in our universe

The US National Aeronautics and Space Administration (NASA) says something strange is happening in our universe. Scientists are studying new data from the Hubble Space Telescope. They say that the expansion rate of the universe has become much faster than expected.

The expansion of the universe.

This new study analyzed 30 years of data from the famous space telescope, providing the most accurate estimate yet of how fast the universe is expanding.

Nobel laureate Adam Riess, of NASA's Space Telescope Management Science Institute (STScI) and Johns Hopkins University (Baltimore, Maryland), said the biggest update on the Hubble constant and results The results of distance markers of galaxies show that the cosmic distance has expanded twice as much as before.

'You're getting the most accurate measurement of the expansion rate of the universe, from the telescope's gold standard and the cosmic mile,' he said.

The Hubble constant is a very special number. It can give scientists a long-standing view of the universe.

NASA says the Hubble telescope has calibrated more than 40 of these mile markers since it was launched into space in 1990.

Research into how the universe is expanding and its expansion rate dates back to 1920. When measurements by Edwin P Hubble and Georges Lemaitre showed that our extragalactic galaxies are not standing still. In fact, they are moving away from us, as NASA explained in a blog post.

Mr. Hubble added that galaxies are moving at an unequal, and increasing, speed. The farther galaxies are from Earth, the faster they move. Since then, scientists have been trying to understand the phenomenon and measure the rate of this expansion. Now, however, with data from Hubble, it seems that the aforementioned expansion is even faster than the models predicted.

Observations show that the megabytes per second (Mb/s) speed is not the expected 67.5 (± 0.5) km/s, but 73 (±1) km/s.

Observations also show that other galaxies are accelerating away from our own Milky Way.

But scientists still haven't been able to figure out why, so for now all they can say is that something strange is going on.

Officials said: 'The reason for this difference remains a mystery. But the Hubble data, which includes various cosmic objects as distance markers, supports the idea that something strange is going on. It may involve an entirely new physical transformation.'

When it comes to measuring stars, the Hubble Space Telescope is one of the most powerful instruments the world has ever known. Hubble is currently on a larger mission to determine how quickly our universe is expanding.

As new data begins a new round of our assessment of the expansion of the universe, scientists are now awaiting data from the new James Webb Space Telescope, which will allow us to deepen our understanding of the universe. this problem.

NASA said: 'The James Webb Space Telescope will expand on Hubble's work to display these cosmic landmarks at greater distances or with sharper resolutions.'

This telescope has just been launched into space and will soon deliver the first observations.
