Our pioneering scientists from the Institute for Computational Cosmology used supercomputer simulations to reveal an alternate explanation for the Moon's origin, as a satellite placed immediately into orbit following a giant impact between Earth and a Mars-sized body.
The researchers created the highest resolution simulations yet produced to study the Moon's origin 4.5 billion years ago. Cosmic ray protons reveal new spectral structures at high energies

Cosmic rays constitute high-energy protons and atomic nuclei that originate from stars (both within our galaxy and from other galaxies) and are accelerated by supernovae and other high-energy astrophysical objects. Our current understanding of the Galactic cosmic ray energy spectrum suggests that it follows a power-law dependence, in that the spectral index of protons detected within a certain e Satellites detect methane plume in Nord Stream leak

Following unusual seismic disturbances in the Baltic Sea, several leaks were discovered last week in the underwater Nord Stream 1 and 2 gas pipelines, near Denmark and Sweden. Neither pipeline was transporting gas at the time of the blasts, but they still contained pressurised methane – the main component of natural gas – which spewed out producing a wide stream of bubbles on the sea surface.
With the unexplained gas release posing a serious question about the incident’s environmental impact, a suite of complementary Earth observation satellites carrying optical and radar imaging instruments were called

ESA astronaut Samantha Cristoforetti will soon complete her second mission to the International Space Station, Minerva.
She was launched from Kennedy Space Center in late April, and since then has supported numerous European and international science experiments, as well as taken responsibility for all operations within the US Orbital Segment. In July 2022 she performed her first spacewalk, during which she carried out work in the Russian segment to bring the European Robotic Arm into operation. At the end of September 2022, she became the first European woman to hold the role of crew commander on the Station.

A SpaceX rocket carrying a Russian crew member blasted off from Florida Wednesday on a voyage that carries significant symbolism as war rages in Ukraine.
Anna Kikina, the only female cosmonaut in service, is part of the Crew-5 mission, which also includes one Japanese and two American astronauts.

Two new communications satellites are deployed into space after launching aboard an Atlas V rocket from Cape Canaveral Space Force Station, Fla.
The United Launch Alliance launch went smoothly with liftoff at 5:36 p.m. Tuesday, followed by the jettisoning of the Atlas V's three solid rocket boosters two minutes later and the separation of its first stage about 4.5 minutes after liftoff.

SpaceX Juno gets highest-resolution close-up of Jupiter's moon Europa
Wednesday, 05 October 2022 20:14 Write a comment
Observations from the spacecraft's pass of the moon provided the first close-up in over two decades of this ocean world, resulting in remarkable imagery and unique science.
The highest-resolution photo NASA's Juno mission has ever taken of a specific portion of Jupiter's moon Europa reveals a detailed view of a puzzling region of the moon's heavily fractured icy crust.
The image covers about 93 miles (150 kilometers) by 125 miles (200 kilometers) of Europa's surface, revealing a region crisscrossed with a network of fine grooves and double ridges (pairs of long parallel lines indicating elevated features in the ice). Near the upper right of the image, as well as just to the right and below center, are dark stains possibly linked to something from below erupting onto the surface.
