July 13, 2023 —Scientists have applied a promising new method to search for dark matter particles in a particle accelerator. The method is based on the observation of the spin polarization of a particle beam in a ...
July 12, 2023 —科学家获得至关重要的见解火星的历史and potential for supporting ...
July 11, 2023 —Mars rovers have teams of human experts on Earth telling them what to do. But robots on lander missions to moons orbiting Saturn or Jupiter are too far away to receive timely commands from Earth. ...
July 11, 2023 —Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called 'impossible early galaxy ...
July 3, 2023 —Quasars are the supermassive black holes at the centres of early galaxies. Scientists have unlocked their secrets to use them as 'clocks' to measure time near the beginning of the ...
June 29, 2023 —Scientists have revealed a uniquely different image of our galaxy by determining the galactic origin of thousands of neutrinos -- invisible 'ghost particles' which exist in great quantities ...
June 29, 2023 —A study offers new insights into how water from melting ice could have played a recent role in the formation of ravine-like channels that cut down the sides of impact craters on ...
June 29, 2023 —Galaxies are not scattered randomly across the universe. They gather together not only into clusters, but into vast interconnected filamentary structures with gigantic barren voids in between. This ...
June 29, 2023 —Black holes, some of the most captivating entities in the cosmos, possess an immense gravitational pull so strong that not even light can escape. The groundbreaking detection of gravitational waves ...
June 29, 2023 —You can't see or feel it, but everything around you -- including your own body -- is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing ...
June 28, 2023 —The star would have inflated up to 1.5 times the planet's orbital distance -- engulfing the planet in the process -- before shrinking to its current size at only one-tenth of that ...
June 28, 2023 —For the first time, the James Webb Space Telescope has revealed starlight from two massive galaxies hosting actively growing black holes -- quasars -- seen less than a billion years after the Big ...
June 27, 2023 —Magnetotactic bacteria, which can align with the Earth's magnetic field, have been discovered in a new location. Previously observed on land and in shallow water, analysis of a hydrothermal vent ...
June 22, 2023 —The cosmos is a unique laboratory for testing the laws of physics, in particular those of Euler and Einstein. Euler described the movements of celestial objects, while Einstein described the way in ...
June 22, 2023 —Isotope ratios found in meteorites suggest that a supernova exploded nearby while the Sun and Solar System were still forming. But the blast wave from a supernova that close could have potentially ...
June 22, 2023 —Astronomers studying a powerful gamma-ray burst, may have detected a never-before-seen way to destroy a star. Unlike most GRBs, which are caused by exploding massive stars or the chance mergers of ...
