The rotation period of Uranus was estimated to be 17.24 hours in 1986 from radio auroral measurements made by NASA’s Voyager 2 spacecraft. The post Astronomers Measure Rotation Rate of ...

Researchers from ETH Zurich, SETI Institute, the Università di Roma ‘Tor Vergata’ and the University of Belgrade have explored how many exoplanets astronomers should observe and understand before declaring that ...

The mass of the supermassive black hole in the center of the Large Magellanic Cloud, a small satellite galaxy of the Milky Way, is about 600,000 solar masses. The post ...

For a century, astronomers have been studying Barnard’s star in the hope of finding planets around it. The post Astronomers Find Evidence for Four Sub-Earth Exoplanets around Barnard’s Star appeared ...

Using data from the APOGEE survey, astronomers from the Leibniz Institute for Astrophysics Potsdam, the University of Vienna and Paris Observatory have reconstructed the properties of ‘hidden’ stars within the ...

One of these exoplanets, HD 20794d, is likely to be a rocky planet in the habitable zone of its parent star, the G-dwarf HD 20794. The post Astronomers Confirm Presence ...

Using data from the NASA/ESA Hubble Space Telescope and the the Keck Cosmic Web Imager at W.M. Keck Observatory, astronomers have identified nine rings -- more than previously detected by ...

The candidate planetary system, detected with the microlensing method, is thought to move at least 540 km per second (1.2 million mph). The post Astronomers May Have Discovered Fastest-Moving Exoplanet ...

An Einstein ring (also known as an Einstein-Chwolson ring or Chwolson ring) is created as the light from distant objects, like galaxies, pass by an extremely large mass, like a ...

Astronomers have imaged planetesimal belts in 74 planetary systems as part of the REsolved ALMA and SMA Observations of Nearby Stars (REASONS) survey. The post Astronomers Discover Exocometary Belts around ...
