NASA Spots Something Strange In Space

( “Something strange” is happening in the universe, according to the National Aeronautics and Space Administration (NASA).

NASA arrived at this conclusion by reviewing data from the Hubble Space Telescope, which has recorded the current rate of expansion of the universe significantly quicker than the rate of expansion at the Big Bang.

NASA states that the explanation of this mismatch remains a mystery. However, Hubble data, which includes a wide range of cosmic objects that serve as distance markers, supports the hypothesis that something strange is happening, maybe involving fresh new physics.

Dark Energy Survey director Kathy Romer said that scientists had expected that gravity would slow the expansion of the cosmos over time. The cosmos is growing, but it is expanding quicker and faster as time passes; because it’s been over 14 billion years since the Big Bang, we’d anticipate the expansion to slow down as time passes.

NASA added that .one of the key arguments for the price and remarkable technological effort, when NASA dreamed of a vast space telescope in the 1970s, was to be able to discern Cepheids, stars that brighten and wane regularly visible inside our Milky Way and other galaxies.

Scientists estimated distances in the cosmos using Cepheids, discovered by astronomer Henrietta Swan Leavitt in 1912. They then employed Type Ia supernovae, exploding stars, to estimate higher distances. Scientists might estimate the Hubble constant, named after astronomer Edwin Hubble, which can be used to determine the universe’s age by calculating the expansion rate, using both ways.

Nobel Laureate Adam Riess, who directs SHOES, a group that studies the expansion rate of the cosmos, said that we’re receiving the most exact gauge of the universe’s expansion rate from the gold standard of telescopes and cosmic mile markers. This is what the Hubble Space Telescope was designed to accomplish, and we’re doing it with the greatest tools we have. This is undoubtedly Hubble’s magnum achievement because even doubling this sample size would require another 30 years of Hubble’s life.

Because of Hubble’s ability to employ a considerable sample size, Riess estimated that the chances of astronomers making a mistake were one in a million.

According to, Hubble and other observatories verified that the universe was accelerating in its expansion. Riess and collaborators got the Nobel in 2011 after Hubble, and other observatories showed that the universe was accelerating in its expansion.
