Using data from the 8.2-metre Subaru Telescope, an international team led by Japanese researchers has made a 3-D map of 3,000 galaxies 13 billion light-years from Earth. Based on this comprehensive survey — the first such study at this great distance — the team was able to confirm that Einstein’s general theory of relativity is still valid.
Super-luminous supernovae (SLSNe) are a relatively new and rare class of stellar explosions, 10 to 100 times brighter than normal supernovae. According to a new model, researchers have found that highly magnetised, rapidly spinning neutron stars called magnetars could explain the energy source behind SLSNe.
You might think that astronomers could easily tell the difference between a black hole and a white dwarf — but nature can be deceptive. Astronomers from the Sloan Digital Sky Survey (SDSS) have just announced the results of a new study that reveals the true origin of puzzling light from nearby galaxies.
Around 37,000 citizen scientists combed through 430,000 images to help an international team of researchers to discover 29 new gravitational lens candidates through Space Warps — an online classification system which guides citizen scientists to become lens hunters, giving the public a chance to make their own scientific discoveries.
