– Universe Universe News NASA's Hubble Telescope Sees Farthest Galaxy Ever Seen NASA’s Hubble Space Telescope has spotted the farthest galaxy ever seen, stretching back to within a few hundred million years of the Big Bang. The galaxy is so far away, its light has taken 13.2 billion years to reach our telescopes — about 750 million years after the Big Bang. The Discovery of the First Exoplanet Around a Sun-Like Star In 1995, a group of astronomers from the Geneva Observatory announced the discovery of the first exoplanet around a sun-like star. The planet, 51 Pegasi b, orbits the star 51 Pegasi in the constellation Pegasus, located about 50 light-years from Earth. NASA’s Chandra Telescope Shows Vast Halo of Hot Gas Around Milky Way NASA’s Chandra X-ray Observatory has discovered a vast halo of hot gas that extends hundreds of thousands of light-years above and below the plane of the Milky Way. The halo is made up of particles that were heated to millions of degrees by supernovae explosions and other energetic events. Videos The Universe: From the Big Bang to Now This video takes a look
The concept of dark energy is often proposed to account for the accelerated expansion of the universe observed in cosmological studies. However, this phenomenon may not stem from energy itself but rather from the complex interplay of geometrical and observational effects.
Astronomers have discovered a galaxy that has been "frozen in time" for billions of years. Like a celestial dinosaur fossil, this galaxy could reveal the secrets of cosmic evolution.
