Milky Way May Have 100 Faint Satellite Galaxies

A new model suggests the Milky Way should have an additional 100 or so very faint satellite galaxies awaiting discovery.

Something is syncing the movements of galaxies

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.

The mystery of the galaxy with no dark matter

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.

Unusual galaxies defy dark matter theory

Researchers from Yale University claim to have found stronger evidence to confirm that galaxies with little or no dark matter do really exist.

Milky Way tips the scales at 1.5 trillion solar masses

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.

Dark matter on the move

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'.

Our universe: An expanding bubble in an extra dimension

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.

Astonishing New Theory Could Explain Universe’s Missing 95%

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.

A swarm of robots assembled to detect effects of dark energy

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.

Dark Matter and Energy Are Real Reveals Final Data of Planck Mission

The Planck mission launched in 2009 has finally reached its ending point. So far the standard model of cosmology has survived all the tests.

Life May Be Billions of Times More Common in the Multiverse

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.

Could dark matter atoms explain a recent observation?

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.

Hubble finds first galaxy in the local universe without dark matter

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.

Simple telescope picks up hint of the Universe’s first stars, 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.

Hubble data indicate universe growing faster than expected

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.
