In the recent past, space missions dedicated to the study of astrophysical signals in the high-energy spectrum revealed a series of enigmatic excesses not predicted by the theoretical models. In order to find an explanation for these anomalies, many solutions have been proposed. The most exciting hypothesis invokes the contribution […]

Heart of darkness: A view of the accretion disc around the supermassive black hole, with jet-like structures flowing away from the disc. The extreme mass of the black hole bends spacetime, allowing the far side of the accretion disc to be seen as an image above and below the black […]

ANIMATION On April 20, 2021, ESA will host the 8th European Conference on Space Debris from Darmstadt, in Germany. Scientists, engineers, industry experts, and policymakers will spend the virtual four-day conference discussing the latest issues surrounding space debris. They will exchange the latest research, try to come up with solutions […]

Credit: NASA/JPL-Caltech The Ingenuity team has identified a software solution for the command sequence issue identified on Sol 49 (April 9) during a planned high-speed spin-up test of the helicopter’s rotors. Over the weekend, the team considered and tested multiple potential solutions to […]

A standoff detonation of a nuclear device irradiates an asteroid and deposits energy at and beneath the surface. In this work, two neutron yields (50 kt and 1 Mt) and two neutron energies (14.1 MeV and 1 MeV) were the primary case studies compared side-by-side. The black dots represent the […]

Credit: Australian National University Researchers at the Australian National University (ANU) have harnessed a technique that helps telescopes see objects in the night sky more clearly to fight against dangerous and costly space debris. The researchers’ work on adaptive optics—which removes the haziness caused by turbulence in the atmosphere—has been […]
