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.
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.
Swedish researchers have devised a new model for the Universe, that may solve the enigma of dark energy. They proposes a new structural concept of a universe that rides on an expanding bubble in an additional dimension.
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 Dark Energy Spectroscopic Instrument, or DESI, is being assembled for a five-year mission at the prime focus of the Mayall Telescope, to measure the spectra of more than 30 million galaxies and quasars.
The Planck mission launched in 2009 has finally reached its ending point. So far the standard model of cosmology has survived all the tests.
While there is no physical evidence that parallel universes exist, the theories that explain how our universe came to be seem to suggest that they are inevitable.
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.
Lengthy observations by the Hubble Space Telescope indicate the universe is expanding faster than predicted by standard models and that Einstein’s cosmological constant, thought by many to define dark energy, may not be so constant after all.
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.
Results from the first data release of the Dark Energy Survey include eleven new stellar streams in the Milky Way galaxy.
