<p style="text-align:center"></p> <p>Scientists using ESA’s XMM-Newton space telescope have discovered that a curious dead star has been hiding one of the strongest magnetic fields in the Universe all along, despite earlier
<p style="text-align:center"></p> <p>NASA’s Hubble Space Telescope has provided the strongest evidence yet that short-duration gamma-ray bursts are triggered by the merger of two small, super-dense stellar objects, such as a pair
<p>During a powerful solar blast on March 7, NASA’s Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun. The discovery heralds Fermi’s new
<p>Astronomers are actively hunting a class of supermassive black holes throughout the universe called blazars thanks to data collected by NASA’s Wide-field Infrared Survey Explorer (WISE). The mission has revealed
<p>The human eye is crucial to astronomy. Without the ability to see, the luminous universe of stars, planets and galaxies would be closed to us, unknown forever. Nevertheless, astronomers cannot
