After a three-year shutdown for repairs and upgrades, the collider has resumed shooting protons around its 17-mile electromagnetic underground racetrack. In early July, the collider will begin crashing these particles together to create sparks of primordial energy.
The observations from the European Space Agency’s Gaia probe cover almost two billion stars — about 1 percent of the total number in the galaxy — and are allowing astronomers to reconstruct our home galaxy’s structure and find out how it has evolved over billions of years.
NASA’s effort will be led by Simons Foundation President David Spergel and Daniel Evans of NASA’s science mission directorate, and would examine observations of events that cannot be identified as aircraft or known natural phenomena.
On certain types of machine learning tasks, quantum computers have an exponential advantage over standard computation, researchers report in Science. And the team showed that the advantage holds up in real-world tests.
