A new study published in the Astrophysical
Journal Letters has reported that the universe is expanding faster than
expected. According to scientists, this would require new physics to better
understand the cosmos.
New measurements from NASA’s Hubble Space
Telescope has confirmed that the Universe is expanding about 9% faster than
expected based on its trajectory seen shortly after the Big Bang. The
astronomers had used Hubble to observe 70 pulsating stars called Cepheid
variables in the Large Magellanic Cloud.
The Hubble Space Telescope (HST) is world’s
first space-based optical telescope that was launched into low Earth orbit in
1990. It still remains operational. It has been named after astronomer Edwin
It is one of NASA’s Great Observatories. NASA’s
series of Great Observatories satellites are four large, powerful space-based
astronomical telescopes. The telescopes other than Hubble include the Compton
Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space
