A longstanding ‘conspiracy’ in astronomy—that stars and dark matter are interacting in inexplicable ways—has been overturned by an international team of astronomers, in a paper in Monthly Notices of the Royal Astronomical Society. Go to Source Chinese astronomers have conducted multi-frequency polarimetric observations of a quasar known as 1604+159. Results of the observational campaign, published August 13 on the pre-print server arXiv, shed more light on the properties of this quasar, including its morphology and magnetic field. Go to Source The Kibble–Zurek (KZ) mechanism is a theoretical framework introduced by physicists Tom Kibble and Wojciech Zurek. This framework essentially describes the formation of topological defects while systems undergo non-equilibrium phase transitions. Go to Source The idea that NASA has encountered Alien life during the Apollo missions has aroused the curiosity of thousands of experts in the field for decades. Ever since NASA successfully landed on the moon, people have wondered whether or not the astronauts on the lunar surface—and during their trip to the moon—witnessed things they couldn’t […] A rocket engine exploded during a test launch at Britain’s new spaceport in northern Scotland, officials said Tuesday, in a setback for the UK’s fledgling space sector. Go to Source We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets—planets that orbit another star outside our solar system. Go to Source Four members of a SpaceX mission that will carry out the first ever private spacewalk arrived in Florida on Monday ahead of their takeoff next week. Go to Source Monday’s supermoon is the first of four this year. Go to Source Areas of space have wildly different temperatures depending on whether they are directly in sunlight or not. For example, temperatures on the moon can range from 121 °C during the lunar “day” (which lasts for two weeks), then drop down to -133 °C at night, encompassing a 250 °C swing. Go to Source […] Solar storms captured the imagination of much of the American public earlier this year when auroras were visible well south of their typical northern areas. As the sun ramps into another solar cycle, those storms will become more and more common, and the dangers they present to Earth’s infrastructure will continue to increase. Go to […] There’s a link between Earth’s ocean salinity and its climate. Salinity can have a dramatic effect on the climate of any Earth-like planet orbiting a sun-like star. But what about exoplanets around M-dwarfs? Go to Source Researchers have identified the specific locations from which most of the approximately 200 Martian meteorites originate. They’ve traced the meteorites to five impact craters within two volcanic regions on the red planet called Tharsis and Elysium. Their study was published recently in the journal Science Advances. Go to Source Φsat-2, ESA’s groundbreaking cubesat designed to revolutionize Earth observation with artificial intelligence, has launched. Go to Source Augmented reality (AR) has evolved from a futuristic concept to a widespread technology, thanks to advancements in microdisplay technologies, ultracompact imaging optics, and high-speed digital processors. Go to Source Scientists from the National University of Singapore (NUS) have shown that excitonic resonances and transitions between excitons can significantly increase the efficiency of generating entangled photon pairs. This could lead to the development of efficient ultrathin quantum light sources. Go to Source |
