Feb. 16, 2023 —一个peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most ...
Feb. 8, 2023 —一个stronomers have uncovered striking new evidence for a mass migration of stars into the Andromeda Galaxy. Intricate patterns in the motions of stars reveal an immigration history very similar to that ...
Feb. 1, 2023 —What happened shortly after the universe was born in the Big Bang and began to expand? Bubbles occurred and a previously unknown phase transition happened, according to particle ...
Jan. 31, 2023 —一个group of scientists have released one of the most precise measurements ever made of how matter is distributed across the universe ...
Jan. 4, 2023 —In giant clusters of hundreds or thousands of galaxies, innumerable stars wander among the galaxies like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any ...
Dec. 15, 2022 —Black holes are surrounded by an invisible layer that swallows every bit of evidence about their past. Researchers are now using machine learning and supercomputers to reconstruct the growth ...
Dec. 12, 2022 —How are galaxies born, and what holds them together? Astronomers assume that dark matter plays an essential role. However, as yet it has not been possible to prove directly that dark matter exists. A ...
Dec. 5, 2022 —Studying an atomic clock on-board a spacecraft inside the orbit of Mercury and very near to the Sun could be the trick to uncovering the nature of dark ...
Nov. 18, 2022 —New data throws out the textbook picture of a spherical stellar halo and reinforces a dynamic origin story of two galaxies that collided billions of years ...
Nov. 17, 2022 —NASA's James Webb Space Telescope has revealed the once-hidden features of the protostar within the dark cloud L1527, providing insight into the beginnings of a new star. These blazing clouds ...
Nov. 11, 2022 —The Subaru Telescope successfully demonstrated engineering first light with a new instrument that will use about 2400 fiberoptic cables to capture the light from heavenly objects. Full operation is ...
Nov. 11, 2022 —一个n international research team has succeeded in significantly narrowing the scope for the existence of dark matter. The experiment makes an important contribution to the search for these ...
Oct. 19, 2022 —一个nalyzing more than two decades' worth of supernova explosions convincingly bolsters modern cosmological theories and reinvigorates efforts to answer fundamental ...
Sep. 26, 2022 —一个stronomers have assembled the largest-ever compilation of high-precision galaxy distances, called ...
Sep. 8, 2022 —Early in its history, shortly after the Big Bang, the universe was filled with equal amounts of matter and 'antimatter' -- particles that are matter counterparts but with opposite charge. ...
Sep. 6, 2022 —Physicists and astronomers have studied gamma rays caused by the Sagittarius Dwarf, a small neighboring galaxy of our Milky Way. They showed that all the observed gamma radiation can be explained by ...
一个ug. 26, 2022 —Physicists have built a quantum scale heat pump made from particles of light. This device brings scientists closer to the quantum limit of measuring radio frequency signals, useful in for example the ...
一个ug. 5, 2022 —一个ccording to the standard model of cosmology, the vast majority of galaxies are surrounded by a halo of dark matter particles. This halo is invisible, but its mass exerts a strong gravitational pull ...
一个ug. 1, 2022 —Using Cosmic Microwave Background (CMB) radiation instead of visible light allows scientists to determine the distribution of dark matter several billion years earlier than previously ...
July 22, 2022 —一个bout three years ago, a team of astronomers went looking for the universe's missing mass, better known as dark matter, in the heart of an atom. Their expedition didn't lead them to dark ...
