Over the past decade or so, a number of astrophysics studies have detected an excess of gamma-ray radiation at the center of our galaxy. Despite the many attempts to understand this unexpected surplus of radiation, now known ...
Using a 3-D mapping technique, astronomers from Sweden and Germany have explored a nearby molecular cloud known as Orion A. The new study unveils more details about the structure and nature of this cloud. The research was ...
Black holes, regions in space with such an intense gravitational field that no matter or radiation can escape from them, are among the most mysterious and fascinating cosmological phenomena. Over the past five years or so, ...
The hypothetical Planet Nine, assumed to be lurking somewhere in the outskirts of our solar system, may not be a planet at all. A new study, published September 24 on the arXiv pre-print server, suggests that the mysterious ...
The universe is continuously expanding, yet the exact rate at which it does so remains unclear, and has so far only been approximated using NASA's Hubble Space Telescope and other similar instruments. Moreover, in recent ...
Astronomers on Wednesday unveiled the first photo of a black hole, one of the star-devouring monsters scattered throughout the Universe and obscured by impenetrable shields of gravity.

A team with members from institutions across the U.S. has used an existing solar model to predict the ability of exoplanets to withstand localized stellar wind. In their paper published in Proceedings of the National Academy ...
(Phys.org)—Recent gravitational wave detections have allowed physicists to confirm with greater and greater precision what Einstein predicted over 100 years ago in the theory of general relativity: that gravity does not ...
(Phys.org)—High-energy protons, nuclei, and other particles are constantly showering down on Earth's atmosphere from space, but the origins of these cosmic rays is unknown. One possibility is that the cosmic rays come from ...
(Phys.org)—A collaborative of researchers from several U.S. universities has published a new paper that explains the major contradictions presented by the prevailing cold dark matter (CDM) cosmological model, and proposes ...
