Read moreThe targets of this search were two nearby neutron stars known to have strong magnetic fields, as well as the Milky Way's center, which is estimated to host half a billion neutron stars. Since no signal was seen, the team was able to impose the strongest limits to date on axion dark matter particles of a few micro electron-volt mass.

Read moreDespite searching with the Chandra X-ray Observatory and Hubble Space Telescope, astronomers have no evidence that a distant black hole estimated to weigh between 3 billion and 100 billion times the mass of the sun is anywhere to be found. This missing black hole should be in the enormous galaxy in the center of the galaxy cluster Abell 2261, which is located about 2.7 billion light-years from Earth.

Read moreAstronomers discovered an exotic binary system composed of two young planet-like objects, orbiting around each other from a very large distance. Although these objects look like giant exoplanets, they formed in the same way as stars, proving that the mechanisms driving star formation can produce rogue worlds in unusual systems deprived of a Sun.
