In the Universe, dark matter and standard matter "talk" to each other using a secret language. This "discussion" happens thanks to gravity, scientists say, but not in a way they can fully comprehend. A new SISSA study published in "The Astrophysical Journal" sheds light on this long-standing issue.
The authors of the research, Ph.D Student Giovanni Gandolfi and supervisors Andrea Lapi and Spinning stars shed new light on strange galactic signal

Researchers from The Australian National University (ANU) have found an alternative explanation for a mysterious gamma-ray signal coming from the centre of the galaxy, which was long claimed as a signature of dark matter.
Gamma-rays are the form of electromagnetic radiation with the shortest wavelength and highest energy.
Co-author of the study Associate Professor Roland Crocker said What is CAPSTONE?

A microwave oven-sized CubeSat weighing just 55 pounds will serve as the first spacecraft to test a unique, elliptical lunar orbit as part of the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE). As a pathfinder for Gateway, a Moon-orbiting outpost that is part of NASA's Artemis program, CAPSTONE will help reduce risk for future spacecraft by vali Blue Canyon Technologies expands into GEO with its first cubesat

Blasting Earth's location out to potential aliens is a controversial idea. Two teams of scientists are doing it anyway

If a person is lost in the wilderness, they have two options. They can search for civilization, or they could make themselves easy to spot by building a fire or writing HELP in big letters. For scientists interested in the question of whether intelligent aliens exist, the options are much the same.
For over 70 years, astronomers have been scanning for radio or optical signals from other civilizations in the search for extraterrestrial intelligence, called SETI. Most scientists are confident that life exists on many of the 300 million potentially habitable worlds in the Milky Way galaxy.
