Gravitational waves could prove the existence of the quark-gluon plasma

Computer models of merging neutron stars predicts how to tell when this happens Goethe University Frankfurt Neutron stars are among the densest objects in the universe. If our Sun, with its radius of 700,000 kilometres were a neutron star, its mass would be condensed into an almost perfect sphere with a radius of around 12…

Kepler-1649c: Earth-Size, Habitable Zone Planet Hides in Plain Sight

From NASA April 16, 2020 A team of transatlantic scientists, using reanalyzed data from NASA’s Kepler space telescope, has discovered an Earth-size exoplanet orbiting in its star’s habitable zone, the area around a star where a rocky planet could support liquid water. Scientists discovered this planet, called Kepler-1649c, when looking through old observations from Kepler, which the…

An update on Comet ATLAS…it is breaking apart

Guest post by Paul Dorian This photograph was taken in Switzerland a few days and it shows three fragments of Comet ATLAS confirming what other amateur astronomers have witnessed…the breaking apart of this once-promising comet.

Doubts about basic assumption for the universe

Study by the Universities of Bonn and Harvard questions a fundamental principle of cosmology University of Bonn No matter where we look, the same rules apply everywhere in space: countless calculations of astrophysics are based on this basic principle. A recent study by the Universities of Bonn and Harvard, however, has thrown this principle into…

Hubble Finds Best Evidence for Elusive Mid-Sized Black Hole

From NASA March 31, 2020 Astronomers have found the best evidence for the perpetrator of a cosmic homicide: a black hole of an elusive class known as “intermediate-mass,” which betrayed its existence by tearing apart a wayward star that passed too close. Weighing in at about 50,000 times the mass of our Sun, the black…

Astronaut urine to build moon bases

FECYT – Spanish Foundation for Science and Technology The modules that the major space agencies plan to erect on the Moon could incorporate an element contributed by the human colonizers themselves: the urea in their pee. European researchers have found that it could be used as a plasticizer in the concrete of the structures. NASA,…

Chandra Data Tests ‘Theory of Everything’

March 19, 2020 One of the biggest ideas in physics is the possibility that all known forces, particles, and interactions can be connected in one framework. String theory is arguably the best-known proposal for a “theory of everything” that would tie together our understanding of the physical universe. Despite having many different versions of string…
