The radio signature is exactly what we’d expect from a water-rich comet,” said one of the researchers, which captures the ...

The distribution of normal matter precisely determines gravitational acceleration in all common types of galaxies, a team led by Case Western Reserve University researchers reports. The team has shown ...

One point of evidence in support of dark matter is the way in which the speed of stars, gas and dust in a galaxy varies with their distance from the center of the galaxy, known as the galactic ...

What can be inferred if a comet from another star system accelerates in a manner that our models cannot fully account for? That is the question at the center of the latest storm of scientific ...

Figure 1: Generation and application of microvortices. A simple calculation of the radial acceleration from the average flow rates in the microchannel overestimates the acceleration that we observed ...

Dynamic galaxy: can the rotation of the spiral galaxy NGC 1232 be explained by MOND? (Courtesy: ESO) Can modified Newtonian dynamics (MOND) explain the curious behaviour of rotating galaxies? Two ...

Electrons trapped in the Van Allen radiation belt surrounding the Earth can have several megaelectronvolts of energy. Scientists believe that either these charged particles originate from the outer ...

The team has shown this radial acceleration relation exists in nearby high-mass elliptical and low-mass spheroidal galaxies, building on last year's discovery of this relation in spiral and irregular ...
