For the first time, scientists have directly detected gravitational waves -- ripples in space-time -- in addition to light from the spectacular collision of two neutron stars. This marks the first time that a cosmic event has been observed in both gravitational waves and light.
Earlier this month, NASA said it was prepared to shift its focus away from Mars, and toward the Moon, whenever the current administration gave the “go” for logistical launch. Now the organization will have to put their plans into motion, because the present administration just announced a renewed effort to get back to the Moon, and beyond.
OSIRIS-REx took a picture of the Earth-moon system on Monday (Sept. 25), a few days after performing a "gravity-assist" flyby of our planet that boosted its speed and helped set its course toward the 1,640-foot-wide (500 meters) asteroid Bennu.
A commercial effort to get humans into orbit around Mars in the late 2020s now includes a sleek vehicle to send astronauts down to the surface of the Red Planet. The aerospace company Lockheed Martin late Thursday (Sept. 28) revealed new details for its Mars Base Camp plan, an architecture aimed at building a crewed space station in orbit around the Red Planet that would support long-term exploration at Mars by astronauts on 1,000-day missions.
In August, detectors on two continents recorded gravitational wave signals from a pair of black holes colliding. This discovery, announced today, is the first observation of gravitational waves by three different detectors, marking a new era of greater insights and improved localization of cosmic events now available through globally networked gravitational-wave observatories.
For more than 50 years, Moore's Law has reigned supreme. The observation that the number of transistors on a computer chip doubles roughly every two years has set the pace for our modern digital revolution--making smartphones, personal computers and current supercomputers possible. But Moore's Law is slowing. And even if it wasn't, some of the big problems that scientists need to tackle might be beyond the reach of conventional computers.
Hurricanes have pummeled sea and land on Earth for eons -- but why do these meteorological monsters even exist? Simply put, hurricanes are the atmosphere's attempt to move heat from the warm equatorial regions toward the cold polar regions, meteorologist Phil Klotzbach of Colorado State University said.
Scientists in the United States are nervously watching from the sidelines as the annual budget skirmish heats up in Congress this week. Legislators are back in Washington DC from their August recess with an urgent list of tasks to complete before the country's fiscal year closes at the end of September. In addition to passing a budget to fund the government, they must also raise the debt ceiling so that the country does not default on its loans, and discuss providing emergency-relief funding for victims of Hurricane Harvey.
The FDA said Wednesday it approved Novartis AG's Kymriah for certain children and young adults who suffer from a form of leukemia. "We're entering a new frontier in medical innovation with the ability to reprogram a patient's own cells to attack a deadly cancer," FDA Commissioner Scott Gottlieb said.
A radical new electronic skin monitor developed by Korean and U.S. scientists tracks heart rate, respiration, muscle movement, acceleration, and electrical activity in the heart, muscles, eyes, and brain and wirelessly transmits it to a smartphone, allowing for continuous health monitoring.
