Old and fast spinning neutron stars called millisecond pulsars could be responsible for an unexplained signal from the center of our Milky Way, reports a team of astrophysicists in a new study published in Nature Astronomy.
Back in 2009, gamma-ray data from the Fermi-Large Area Telescope revealed an unexplained, apparently diffuse, signal from the center of the Milky Way. The origin of thi Tracing The Remnants Of Andromeda's Violent History

A detailed analysis of the composition and motion of more than 500 stars revealed conclusive evidence of ancient a collision between Andromeda and a neighboring galaxy. The findings, which improve our understanding of the events that shape galaxy evolution, were presented by Carnegie's Ivanna Escala Monday at the meeting of the American Astronomical Society.

Momentus Inc. (NASDAQ: MNTS) has provided its third Mission Update since the launch of its Vigoride-3 spacecraft on May 25.
As we previously stated in earlier updates on the inaugural flight of the Vigoride orbital transfer vehicle, the spacecraft experienced anomalies after its launch on May 25. Since that time, we have continued work to address the anomalies and identify root causes. Of Smartphone technology provides satellites with increased computing power

Reliable and powerful computers play a central role in spaceflight - for example, computer systems in satellites enable sophisticated Earth observation missions. The German Aerospace Center is developing a new computer architecture that will provide On-Board Computers (OBCs) with more power as well as enabling them to repair themselves.

ESA’s new Ariane 6 heavy-lift rocket is a critical step closer to inaugural launch, following completion of tests to validate launch pad/launcher systems that will keep the vehicle topped up with liquid hydrogen and liquid oxygen in the critical moments before liftoff.
While on the launch pad at Europe’s Spaceport in French Guiana, Ariane 6 relies on a “cryogenic connection system” of umbilical cords carrying its hydrogen and oxygen fuel – liquified at -250C and -180C respectively – as well as helium and nitrogen used for flushing and purging. The tests seen in this video showed that retraction
