Something is causing nothingness to grow, squeezing its way into the gaps between galaxies to gently push the large scale structure of the Universe apart at an ever increasing rate. We call this something "dark energy".
ESA's Euclid space telescope was launched for a six-year mission to shed light on dark energy and matter and chart the largest-ever map of the universe.
Observations of supermassive black holes at the centres of galaxies point to a likely source of dark energy - the "missing" 70% of the Universe.
About a year ago, the XENON1T experiment reported an unexpected signal, or excess, over the expected background. This signal could be attributable to dark energy.
The survey, which included 400 individual scientists from 25 institutions in 7 countries, observed over 226 million galaxies. The goal of the survey was to the distribution of dark matter and the effect of dark energy.
U.S. scientists have precisely measured the total amount of matter making up the cosmos, concluding that dark energy accounts for 69 % of the total mass-energy budget with normal and dark matter being 31.5 %.
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.
An important discrepancy in measurements of the universe’s acceleration has theorists wondering whether we’ve gotten something fundamentally wrong in our understanding of the history of the universe.
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.
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.
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.
Results from the first data release of the Dark Energy Survey include eleven new stellar streams in the Milky Way galaxy.
Merging Neutron Stars Challenge Existing Theories of Gravity and Dark Energy.
New research is adding some deeper insight into the mysterious repulsive force known as dark energy, providing evidence that whatever it might be, its ghostly influence hasn't been constant over time.
