A new model suggests the Milky Way should have an additional 100 or so very faint satellite galaxies awaiting discovery.
Scientists have been gathering a growing well of evidence that our universe may be connected via a vast array of large-scale "structures" that seem to reach out across the cosmos to synchronize the movements of galaxies that are separated by vast distances.
Researchers have clarified one of the mysteries of 2018 in the field of extragalactic astrophysics: the supposed existence of a galaxy without dark matter. New results show that the galaxy is "normal" with dark matter present.
Researchers from Yale University claim to have found stronger evidence to confirm that galaxies with little or no dark matter do really exist.
Using ESA's Gaia spacecraft and NASA’s Hubble Space Telescope, astronomers have come up with the most accurate measurement yet of the Milky Way’s total mass. It contains about 1.5 trillion times the mass of Earth’s Sun.
Scientists have found evidence that dark matter can be heated up and moved around, as a result of star formation in galaxies. The findings provide the first observational evidence for the effect known as 'dark matter heating'.
UK researcher, Jamie Farnes, suggests both dark energy and matter can be unified into a single substance — a negative-mass ‘dark fluid.’ The theory may also prove right a prediction that Albert Einstein made 100 years ago.
The mysterious dark photon will be hunted by the Positron Annihilation into Dark Matter Experiment (PADME) in Italy, which will start collecting data in the next couple of weeks.
The Planck mission launched in 2009 has finally reached its ending point. So far the standard model of cosmology has survived all the tests.
A tiny fraction of dark matter could have a charge, allowing it to interact with regular matter during the time between the Big Bang and formation of the Cosmic Microwave Background, some physicists say.
An international team of researchers using the NASA/ESA Hubble Space Telescope and several other observatories have, for the first time, uncovered a galaxy that is missing dark matter.
A small team of researchers announced that its correspondingly small telescope picked up a signal produced by the very first stars in our Universe.
The simulation consists of 18 simulations covering various scales - each a cubic mock-up of space up to 1 billion light years wide - tracing the evolution of the Universe from just after the Big Bang into the future.
The experiment has directly detected a sudden drop-off in the electrons hitting the satellite.
Dark Energy Survey scientists unveiled the most accurate measurement ever made of the present large-scale structure of dark matter in the Universe.
