It is not a quick radio ruptured, a pulsar, or low-mass star. So what in the heavens is it? Astronomers have found an unusual, repeating radio signal near the center of the Milky Way, and also it differs from any other energy signature ever studied. The center of the Milky Way, as seen by NASA's Chandra,...

Garlick Our galaxy is not as well-blended as scientists occasionally think, according to brand-new research. That new study mainly focuses on the distribution of what astronomers consider metals-- which is genuinely just every component besides hydrogen and helium, even when...
Scientists launched the first set of gamma photon data acquired by the Dark Matter Particle Explorer. Credit: DAMPE Collaboration For the very first time, in May of 2021, China's Dark Matter Particle Explorer (DAMPE) Collaboration directly observed a spectral softening of helium nuclei of around 34TeV. Now, we have even more excellent news from the satellite-based...

Now, it is back with a fantastic...
The fall of a blue ultra-diffuse galaxy into a galaxy system and its subsequent ejection as a red ultra-diffuse galaxy. Credit: MIT The results give a blueprint for finding such systems in deep space's quieter, emptier areas. By definition, dwarf galaxies are tiny and dim, with just a fraction of the stars located in the Milky...
Fast-moving debris from a supernova explosion triggered by a stellar collision crashes into material thrown out earlier, and the shocks cause bright radio emission seen by the VLA. Credit: Bill Saxton, NRAO/AUI/NSF Astronomers have found remarkable evidence that a black hole or neutron star spiraled its way right into the center of a companion star...
Vega is the fifth brightest star, excluding the sun, that can be seen from Earth. (Image credit: NASA/JPL-Caltech) A possible searing-hot planet was spotted by astronomers, orbiting Vega, one of the brightest and most known stars in the sky. Approximately the size of Neptune, the candidate alien planet lies very close to Vega, taking 2.5 Earth...
