Using supercomputer calculations, scientists at the Max Planck Institute for Gravitational Physics in Potsdam and from Japan show a consistent picture for the first time: They modeled the complete process of the collision of a black hole with a neutron star. In their studies, they calculated the process from the final orbits through the merger to the post-merger phase, in which according to thei New radio astronomy survey peers through cosmic dust to investigate the Milky Way

The first results from a mammoth astronomy project aimed at mapping out the origins of our 13.8 billion year old universe have been announced.
An international team of astronomers from around the globe taking part in the project named, COMAP (CO Mapping Array Project) will offer us a new glimpse into this epoch of galaxy assembly, helping to answer questions about what really caused the un ETH researchers remeasure gravitational constant

Researchers at ETH Zurich have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great potential for testing one of the most fundamental laws of nature.
The gravitational constant G determines the strength of gravity - the force that makes apples fall to the ground o Office of Space Commerce to start developing architecture for traffic management

Space weather will delay your trains
Wednesday, 13 July 2022 17:22 Write a comment
Fluctuations in space weather are disrupting train signals and causing significant delays. A project investigating the effect of solar storms on railway signals will be presented this week at the National Astronomy Meeting (NAM 2022) by Cameron Patterson, a Ph.D. student at Lancaster University.
The sun's tendency to affect technology on Earth, as well as in space, is known as space weather. In railways, electric currents caused to flow in the Earth by solar activity can interfere with the normal operation of signals, turning green signals to red even when there is no train nearby.
Patterson says: "Most of us have at one point heard the dreaded words: 'your train is delayed due to a signaling failure,' and while we usually connect these faults to rain, snow and leaves on the line, you may not have considered that the sun can also cause railway signals to malfunction.
SIRI-2 to qualify technologies for radiation detection in space
Wednesday, 13 July 2022 17:10 Write a comment
U.S. Naval Research Laboratory scientists launched the second Strontium Iodide Radiation Instrument (SIRI-2) instrument in December 2021 onboard Space Test Program (STP) Sat-6. SIRI-2, a gamma-ray spectrometer, will demonstrate the performance of europium-doped strontium iodide gamma ray detection technology with sufficient active area for Department of Defense (DoD) operational needs.
The first SIRI mission was launched Dec.
ESA fully cuts Mars mission ties with Russia, angering Moscow
Wednesday, 13 July 2022 15:37 Write a comment
The European Space Agency has officially terminated cooperation with Russia on a mission to put a rover on Mars, with Russia's space chief furiously responding by banning cosmonauts on the ISS from using a Europe-made robotic arm.
The ESA had previously suspended ties on the joint ExoMars mission, which had planned to use Russian rockets to put Europe's Rosalind Franklin rover on the red planet to drill for signs of life, due to Russia's invasion of Ukraine.
ESA Director-General Josef Aschbacher tweeted on Tuesday that because the war and resulting sanctions "continue to prevail", the agency would "officially terminate" ties with Russia on ExoMars and its landing platform.
The firebrand head of Russian space agency Roscosmos Dmitry Rogozin issued an angry response.
"Has the head of the European Space Agency thought about the work of thousands of scientists and engineers in Europe and Russia which has been ended by this decision? Is he prepared to answer for sabotaging a joint Mars mission?" Rogozin said on Telegram.

NASA's James Webb Space Telescope has captured the distinct signature of water, along with evidence for clouds and haze, in the atmosphere surrounding a hot, puffy gas giant planet orbiting a distant Sun-like star.
The observation, which reveals the presence of specific gas molecules based on tiny decreases in the brightness of precise colors of light, is the most detailed of its kind to d
