Quantum optical cooling of nanoparticles
by
•One important requirement to see quantum effects is to remove all thermal energy from the particle motion, i.e. to cool it as close as possible to absolute zero temperature. Researchers …read more Source:: Science
Elusive star has origins close to Big Bang

•Astronomers have found what could be one of the universe’s oldest stars, made almost entirely of materials spewed from the Big Bang. …read more Source:: Science
Laser breakthrough has physicists close to cooling down antimatter
by
•For the first time, physicists at CERN have observed a benchmark atomic energy transition in anithydrogen, a major step toward cooling and manipulating the basic form of antimatter. Antimatter, annihilated …read more Source:: Science
Iron and titanium in the atmosphere of an exoplanet
by
•Exoplanets can orbit close to their host star. When the host star is much hotter than our sun, then the exoplanet becomes as hot as a star. The hottest ‘ultra-hot’ …read more Source:: Science
New model explains what we see when a massive black hole devours a star
by
•A star that wanders too close to the supermassive black hole in the center of its galaxy will be torn apart by the black hole’s gravity in a violent cataclysm …read more Source:: Science
Arrested development: Hubble finds relic galaxy close to home
