Study Suggests Flattened Dark Matter Could Be Behind Milky Way’s Central Gamma-Ray Glow

/in /tarafından

For over a decade, astronomers have been intrigued by a mysterious high-energy gamma-ray glow emanating from the center of the Milky Way. This excess radiation could not be explained by known sources, such as pulsars or supernova remnants. Recent computer simulations now suggest a potential solution: the dark matter surrounding galactic centers may not be spherical, as previously assumed, but rather flattened into a discoidal shape. This configuration could produce a radiation pattern closely matching the unexplained glow observed by NASA’s Fermi space telescope. Devamını Oku

Astronomers Identify ‘Super-Earth’ GJ 251 c as a Top Candidate for Potential Alien Life

/in /tarafından

Astronomers from an international team, including researchers at Penn State, have discovered a new super-Earth exoplanet orbiting the nearby star GJ 251. Named GJ 251 c, the planet has a mass roughly four times that of Earth and is likely rocky. Importantly, it orbits within the star’s habitable zone, the range where conditions could allow liquid water to exist, making it one of the most promising candidates for potentially supporting alien life.

NASA’s Europa Clipper Could Fly Through Comet Tail, Providing Unique Look at Interstellar Material

/in /tarafından

NASA’s Europa Clipper spacecraft, currently en route to study Jupiter’s icy moon Europa, may have a rare opportunity to pass through the tail of an interstellar comet. Between October 30 and November 6, the spacecraft is expected to encounter a stream of charged particles emitted by comet 3I/ATLAS, a visitor from another star system that has been traveling through the solar system for over a year. If the timing aligns, this could allow scientists to study interstellar material directly, without the need to launch a dedicated mission to chase the comet. Devamını Oku
