Planets are formed when dust and rock in a disk around a young star collide and combine to form ever larger bodies. This so-called accretion is not yet fully understood. Astrophysicists at the University of Duisburg-Essen were able to make significant observations of collision speed and electrical charge of the particles through experiments on a […] Almost five years ago, much of the world went quiet for several weeks due to the COVID-19 lockdowns. It went so quiet, in fact, that scholars published a 2024 article in the Monthly Notices of the Royal Astronomical Society: Letters claiming the lack of human activity likely led to the moon’s surface temperatures cooling down […] Using observations from 2017 and 2018, the Event Horizon Telescope (EHT) Collaboration has advanced our understanding of the supermassive black hole at the center of Messier 87 (M87*). This study marks a significant step toward multi-year analysis at horizon scales, in order to investigate the black hole’s turbulent accretion flow. It utilizes a vastly improved […] Using the MeerKAT telescope in South Africa, an international team of astronomers has detected 26 new Galactic radio transients. Most of them turned out to be rotating radio transients (RRATs). The finding is detailed in a research paper published Jan. 14 on the arXiv preprint server.

These devices act as rulers for measuring light, enabling breakthroughs in telecommunications, environmental monitoring, and even astrophysics. But building compact and efficient frequency combs has been a challenge—until now.

Their impressive results in many sciences have helped develop society and humanity as we know of it today. The Antikythera mechanism is according to researchers another product of Greece. There is no […] History had it all working apparently… the first world war happened thousands of years ago according to researchers who have found evidence of the first major military conflict at Jebel Sahaba.At a time when we were commemorating the (barely) one hundred years of the so-called First World War, researchers have discovered traces of […] Go to Source The ISS’s orbit is slowly decaying. While it might seem a permanent fixture in the sky, the orbiting space laboratory is only about 400 km above the planet. There might not be a lot of atmosphere at that altitude. However, there is still some, and interacting with that is gradually slowing the orbital speed of […] Two NASA rocket missions are taking to the Alaskan skies in hopes of discovering why some auroras flicker, others pulsate, and still others are riddled with holes. Understanding these peculiar features is part of NASA’s goal to understand the space environment around our planet, which can affect both spacecraft and astronauts. Go to Source […] When NASA and the Indian Space Research Organization’s (ISRO) new Earth satellite NISAR (NASA-ISRO Synthetic Aperture Radar) launches in coming months, it will capture images of Earth’s surface so detailed they will show how much small plots of land and ice are moving, down to fractions of an inch. Go to Source […] Astronomers have discovered extremely powerful winds pummeling the equator of WASP-127b, a giant exoplanet. Reaching speeds up to 33,000 km/h, the winds make up the fastest jet stream of its kind ever measured on a planet. The discovery was made using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) in Chile and provides unique […] There’s a universe full of black holes out there, spinning merrily away—some fast, others more slowly. A recent survey of supermassive black holes reveals that their spin rates reveal something about their formation history. Go to Source |
