The formation process involved two stages, said Mitchell Begelman, a professor and the chair of CU-Boulder's astrophysical and planetary sciences department. The predecessors to black hole format...
Physics and Astronomy |Rosetta passed over the ocean, just South of the Indonesian island of Java, at exactly 08:45:40 CET, at a speed of 13.34 km/s with respect to Earth at an altitude of 2481 km. The swingby was pre-plann...
Physics and Astronomy |The calculation of variations in the sea level is relatively simple. It is by far more complicated to then determine the change in the water mass. A team of geodesists and oceanographers from the Univ...
Earth Sciences |The findings show that "stellar nurseries" within the first galaxies gave birth to stars at a much more rapid rate than previously expected, the researchers from Durham's Institute for ...
Physics and Astronomy |"Those minor to moderate events along the San Jacinto fault relieve some of the stress built by the constantly moving tectonic plates," said Shimon Wdowinski, research associate professor at...
Earth Sciences |The system works well, and millions rely on it every day, but what tells the GPS satellites where they are in the first place? "For GPS to work, the orbital position, or ephemeris, of the...
Information Technology |This happens during Saturn's equinox, when the sun is directly over Saturn's equator. At this time, the rings, which also orbit directly over the planet's equator, appear edge-on to the...
Physics and Astronomy |The galaxy cluster, known as JKCS041, beats the previous record holder by about a billion light years. Galaxy clusters are the largest gravitationally bound objects in the Universe. Finding such a lar...
Physics and Astronomy |Scientists have a long and unsuccessful history of attempting to convert hydrogen to a metal by squeezing it under incredibly high and steady pressures.Metallic hydrogen is predicted to be a h...
Power and Electrical Engineering |According to the map, the sinking effect in the south could add between 10 and 33 per cent to the projected sea-level rises caused by global warming over the next century. *The projections are...
Earth Sciences |NPL, along with collaborators, produced technical reports for the European Space Agency. The conclusions demonstrated that the lasers were a suitable method for measurement in such missions.Fo...
Physics and Astronomy |So accustomed are we to the sunshine, rain, fog and snow of our home planet that we find it next to impossible to imagine a different atmosphere and other forms of precipitation. To be sure, D...
Physics and Astronomy |But it was a far more modest observatory, located just above sea level in rural Levy County and just down the road from the UF campus, that proved key to a new discovery about what one astronomer term...
Physics and Astronomy |This collective condition is called - named for its intellectual fathers - Bose-Einstein condensate. Physicists at the Physikalisch-Technische Bundesanstalt (PTB) have now succeeded for the first time...
Physics and Astronomy |The flashes, known as gamma ray bursts, are beams of high energy radiation – similar to the radiation emitted by explosions of nuclear weapons – produced by jets of plasma from massive dying stars. ...
