Researchers have developed a new conceptual framework for understanding how stars similar to our Sun evolve. Their framework helps explain how the rotation of stars, their emission of x-rays, and the intensity of their stellar winds vary with time.
NASA's planet hunter, the Kepler space telescope, has captured the brilliant flash of an exploding star's shock wave - what astronomers call the 'shock breakout' of a supernova - for the first time in visible light wavelengths.
An international team of scientists using the NASA/ESA Hubble Space Telescope has combined images taken with the Wide Field Camera 3 with the unprecedented ultraviolet spatial resolution of the Space Telescope Imaging Spectrograph to successfully dissect the young star cluster R136 in the ultraviolet for the first time.
How does the ice on the polar caps change? And which are the geological characteristics of the Earth's crust beneath? What is the structure of the boundary between the Earth's crust and mantle? Geophysicists will be able to answer these questions in the future using gravity field measurements from ESA's GOCE gravity satellite.
A research team using the Atacama Large Millimeter/submillimeter Array (ALMA) has detected the faintest millimeter-wave source ever observed. By accumulating millimeter-waves from faint objects like this throughout the Universe, the team finally determined that such objects are 100% responsible for the enigmatic infrared background light filling the Universe.
A recent observational campaign involving more than two dozen optical telescopes and NASA's space based SWIFT X-ray telescope allowed a team of astronomers to measure very accurately the rotational rate of one of the most massive black holes in the universe.
By pushing NASA's Hubble Space Telescope to its limits, an international team of astronomers has shattered the cosmic distance record by measuring the farthest galaxy ever seen in the universe. This surprisingly bright infant galaxy, named GN-z11, is seen as it was 13.4 billion years in the past, just 400 million years after the Big Bang.
