An international group of astronomers, led by a physicist at the University of St Andrews, has revived an alternative gravity theory.
Headed by Dr Indranil Banik of the School of Physics and Astronomy at St Andrews, the study revealed a high predicted rotation speed of gas in a dwarf galaxy consistent with the previously debunked theory known as Milgromian Dynamics (MOND).
An earlier Human's motion perception revealed by spaceflight: study

Spaceflight, apart from exploring the unknown universe, can also help us, the inhabitants of Earth, to understand how gravity is affecting our brain in its visual perception.
Humans have evolved under the constant influence of gravity, though normally we don't notice it.

Full steam ahead for carbon dioxide monitoring mission

The Copernicus Anthropogenic Carbon Dioxide Monitoring mission has taken another step forward as ESA authorises the mission’s prime contractor, OHB, to continue the development of the first satellite that will take it to being launch-ready and, in parallel, start production on the mission’s second satellite. Celebrated at ESA’s Living Planet Symposium in Bonn, this contract rider follows an initial contract that was signed in 2020.
Did NASA find a mysterious doorway on Mars? No, but that's no reason to stop looking
Monday, 23 May 2022 13:09 Write a comment
For the past 10 years, NASA's Curiosity rover has been trundling around the surface of Mars, taking photos in its quest to understand the history and geology of the red planet and perhaps even find signs of life.
Last week it took a photo which appeared to show a doorway carved into the rock. It's the sort of thing that on Earth might indicate an underground bunker, such as an air-raid shelter.
Seeing is not always believing
At first sight, the picture is totally convincing. At second sight, maybe not. The passage seems to go in only a short way before the steeply descending roof meets the floor.
And then those killjoys at NASA tell us its only about 45 cm high. Still, who said Martians had to be the same height as us? But thengeologists point out several straight-line fractures can be seen in this site, and the "doorway" is where they happen to intersect.
Such a pity. It would have been so exciting if it had been a real doorway.

Swarm unveils magnetic waves deep down
Monday, 23 May 2022 12:00 Write a comment
While volcanic eruptions and earthquakes serve as immediate reminders that Earth’s insides are anything but tranquil, there are also other, more elusive, dynamic processes happening deep down below our feet. Using information from ESA’s Swarm satellite mission, scientists have discovered a completely new type of magnetic wave that sweeps across the outermost part of Earth’s outer core every seven years. This fascinating finding, presented today at ESA’s Living Planet Symposium, opens a new window into a world we can never see.

Japan and the United States said Monday they want to put the first Japanese astronaut on the Moon as the allies deepen cooperation on space projects.
No non-American has ever touched down on the lunar surface, and Japan has previously said it hopes to achieve a Moon landing by the end of this decade.

An autonomous spacecraft exploring the far-flung regions of the universe descends through the atmosphere of a remote exoplanet. The vehicle, and the researchers who programmed it, don't know much about this environment.
With so much uncertainty, how can the spacecraft plot a trajectory that will keep it from being squashed by some randomly moving obstacle or blown off course by sudden, gal Kongsberg Defence and Aerospace orders three surveillance satellites from NanoAvionics
