NASA: Universe expanding faster than expected

  1. 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.
  2. 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.
  3. 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 Hubble.
  4. 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 Telescope
