A star you can see with the naked eye has kept astronomers guessing for decades with its unusually powerful X-rays. Now, thanks to highly precise observations from Japan’s XRISM space telescope, scientists have finally uncovered the source: a hidden white dwarf companion pulling in material and generating extreme heat. This discovery not only solves a 50-year-old mystery surrounding Gamma Cassiopeiae, but also confirms the existence of a long-predicted type of binary star system.

Honor 600 vs. 600 Pro

The age-old question - the Pro or the non-Pro? This time it's either the Honor 600 or the Honor 600 Pro. The latter brings a handful of useful features and hardware upgrades over the regular Honor 600, but also adds another €300 to the bill. Sure, you get a more powerful chipset and a telephoto camera, but the vanilla 600 gets you a long way at a much lower cost.... Read more

For more than 200 years, scientists have struggled to pin down the exact strength of gravity — and one physicist spent a decade chasing the answer while keeping his own results hidden from himself. Stephan Schlamminger and his team at NIST painstakingly recreated a landmark French experiment designed to measure “big G,” the universal gravitational constant that governs everything from falling apples to galaxies. When he finally opened a sealed... Read more

Scientists have achieved something that once sounded almost impossible: using ordinary sunlight to create quantum-linked photon pairs, a phenomenon normally dependent on precise laboratory lasers. By building a sun-tracking system that funnels sunlight through optical fiber into a special crystal, researchers generated strongly correlated photons capable of performing “ghost imaging,” where images are reconstructed indirectly through quantum correlations. Remarkably, the sunlight-powered setup produced imag Read more

Time might be even stranger than Einstein imagined. Physicists are now exploring the possibility that a single clock could exist in a quantum superposition, ticking both faster and slower at the same time — almost like Schrödinger’s cat being both alive and dead simultaneously.
