Astronomers used data from three X-ray satellites and found a black hole that spins at about 50% the speed of light!
Astronomers used X-ray data from NASA’s Chandra X-ray observatory and ESA’s XMM-Newton satellite as well as ultraviolet data from Sloan Digital Sky survey (SDSS) and found evidence that dark energy is getting stronger with time!!
Scientists used the Fermi telescope to measure the entire amount of starlight ever emitted! According to the measurement, the number of photons (particles of visible light) that escaped into space after being emitted by stars translates to 4×1084!! This is 4 followed by 84 zeros!!!
