Researchers at Universitat Autonoma de Barcelona have successfully created a magnetic wormhole connecting two regions of space. This breakthrough technology could lead to more comfortable MRI scans and new medical applications.
Astronomers have solved a mystery over blue hook stars, which form when a star's outer layers are destroyed by rapid rotation. The international team found that these stars consume hydrogen fuel more slowly due to their high spin rates.
The UK-led Beagle 2 Mars Lander has been found on the Martian surface, ending the mystery of its disappearance in 2003. The lander's partial deployment confirms that it successfully touched down on Mars on Christmas Day 2003.
Scientists at NIST and IU developed a tool that calculates fundamental properties of most atoms with historic accuracy, improving the prediction of atomic properties for fields like nuclear medicine and astrophysics. The technique enables precise determination of base energy levels, crucial for fundamental atomic research.
Intermediate-mass black holes can grow in galaxy gas disks through a mechanism similar to giant planet formation. The 'runaway growth' phenomenon allows stellar black holes to swallow stars and increase their mass, potentially creating an intermediate-mass black hole.
