Dark matter proponents theorize that most of the known Universe is actually made of material that doesn’t interact with light, making it invisible and...
The 2017 observations from the Event Horizon Telescope (EHT) of M87*, a 6.5-billion-solar-mass black hole in the center of the giant elliptical galaxy...
Our Solar System contains a large population of icy bodies stretching well beyond the orbit of Neptune. These objects are remnants from the early formation...
At the center of the Milky Way lurks Sagittarius A*, a supermassive black hole that is four million times the mass of the Sun. Located 26,000 light-years...
In a test of Einstein’s theory of general relativity near the supermassive black hole at the center of our Milky Way Galaxy, an international group of...
In a study done in rats, a moderate daily dose of resveratrol — a natural antioxidant found in more than 70 species of plants such as grapes, cranberries,...
An international team of theoretical physicists has found that when gravity is combined with quantum mechanics, no global symmetries are possible.
Quantum...
Physicists from the AEgIS (Antihydrogen Experiment: Gravity, Interferometry, Spectroscopy) Collaboration at CERN have found a new way of making long-lived...
In the final phase of NASA’s Cassini mission, the spacecraft dived between Saturn and its innermost ring, at altitudes 1,616-2,423 miles (2,600-3,900...
At the center of our Milky Way Galaxy lies the 4-million-solar-mass black hole named Sagittarius A*. This gravitational monster is surrounded by a group...
In a new test of Einstein’s theory of gravity, a group of astronomers from the Netherlands, the United States, Australia and Canada has demonstrated...
Dr. Thomas Collett, an astrophysicist and cosmologist at the University of Portsmouth, UK, and co-authors have made the most precise test of Albert Einstein’s...
A team of planetary researchers at the University of Colorado at Boulder has offered up a new theory for the existence of strange trans-Neptunian objects...
A research team led by Rutgers University’s Professor Dennis Kent has documented a gradual shift in Earth’s orbit that repeats regularly every 405,000...
The NASA/ESA Hubble Space Telescope observed the nearby white dwarf star Stein 2051B as it passed in front of a background star. During the close alignment,...
