Dark inflation opens up a gravitational window on the first moments after the Big Bang
Jun 08, 2018
Dark matter and dark energy may have driven inflation, the exponential expansion of the universe moments after the Big Bang. A new cosmological model proposed by physicists at the University of Warsaw, which accounts for ...
Cosmic voids and galaxy clusters could upend Einstein
Jun 05, 2018
It will be possible to use new astronomical mappings of hundreds of thousands of cosmic voids and galaxy clusters to test Einstein's theory of relativity by looking for small deviations in gravity at vast distances – a ...
Could a multiverse be hospitable to life?
May 14, 2018
A Multiverse—where our Universe is only one of many—might not be as inhospitable to life as previously thought, according to new research.
Tiny distortions in universe's oldest light reveal clearer picture of strands in cosmic web
Apr 10, 2018
Scientists have decoded faint distortions in the patterns of the universe's earliest light to map huge tubelike structures invisible to our eyes – known as filaments – that serve as superhighways for delivering matter ...
Astronomers find 72 bright and fast explosions
Apr 02, 2018
Gone in a (cosmological) flash: a team of astronomers found 72 very bright, but quick events in a recent survey and are still struggling to explain their origin. Miika Pursiainen of the University of Southampton will present ...
Beyond the WIMP: Unique crystals could expand the search for dark matter
Mar 20, 2018
A new particle detector design proposed at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) could greatly broaden the search for dark matter—which makes up 85 percent of the total mass ...
Can strongly lensed type Ia supernovae resolve one of cosmology's biggest controversies?
Mar 01, 2018
In 1929 Edwin Hubble surprised many people – including Albert Einstein – when he showed that the universe is expanding. Another bombshell came in 1998 when two teams of astronomers proved that cosmic expansion is actually ...
Six decades of cosmology
Feb 28, 2018
"Cosmologists are often wrong but never in doubt," Russian physicist Lev Landau once said. In the early days, astronomers began by observing and modelling stars in different stages of evolution and comparing their findings ...
Astronomers reveal secrets of most distant supernova ever detected
Feb 20, 2018
An international team of astronomers, including Professor Bob Nichol from the University of Portsmouth, has confirmed the discovery of the most distant supernova ever detected – a huge cosmic explosion that took place 10.5 ...
New chapter begins for kitt peak telescope
Feb 12, 2018
When the Mayall first opened its eye to the sky 45 years ago, it was one of the largest optical telescopes in existence. Designed to be versatile, its mission was to assist astronomers in addressing the wide diversity of ...
