Flat dark matter sheet solves local galaxy motion puzzle
Astronomers have used advanced computer simulations to show that the matter distribution just beyond the Local Group is organized in a vast, flattened structure of dark matter that extends tens of millions of light years. This large scale sheet surrounds the Milky Way and the Andromeda Galaxy and is bordered above and below by enormous voids where galaxies are absent.
For almost a century, Musk merges xAI into SpaceX in bid to build space data centers

Jammertest: strengthening satellite navigation
Video:
00:03:39
Satellite navigation is essential to everyday life, from tracking your morning jog to landing air ambulances. But as reliance on satellite navigation grows, so do the risks associated with its interruption, natural or intentional. To strengthen European resilience in navigation, the European Space Agency (ESA) takes part annually in Jammertest.
Organised on the remote island of Andøya, Norway, Jammertest is the world’s largest open air testing campaign for jamming and spoofing resilience. In September 2025, ESA engineers attended Jammertest with ESA’s mobile navigation lab to test how different systems respond to interference. After this, the data are analysed
