Arctic sea ice thinning faster than expected
Sea ice in the coastal regions of the Arctic may be thinning up to twice as fast as previously thought, according to a new modelling study led by UCL researchers. Sea ice thickness is inferred by measuring the height of the ice above the water, and this measurement is distorted by snow weighing the ice floe down.

Dark Energy Survey releases most precise look yet at the universe’s evolution
The Dark Energy Survey collaboration announced it has created the largest-ever maps of the distribution and shapes of galaxies, tracing both ordinary and dark matter in the universe out to a distance of more than 7 billion light-years. The analysis, which includes the first three years of data from the survey, is consistent with predictions from the current best model of the universe.

Dark matter mapped using light from 100 million galaxies
The largest ever map of dark matter - invisible matter thought to account for 80% of the total matter of the Universe - has been created by a team co-led by UCL researchers, as part of the international Dark Energy Survey (DES). As matter curves space-time, astronomers are able to map its existence by looking at light travelling to Earth from distant galaxies; if the light has been distorted, this means there is matter in the foreground, bending the light as it comes towards us.

Experiments validate the possibility of helium rain in Jupiter and Saturn
Experiments validate the possibility of helium rain in Jupiter and Saturn
Nearly 40 years ago, scientists first predicted the existence of helium rain inside planets composed primarily of hydrogen and helium, such as Jupiter and Saturn. But achieving the experimental conditions necessary to validate this hypothesis hasn't been possible - until now. In a paper published today by Nature , scientists reveal experimental evidence to support this long-standing prediction, showing that helium rain is possible over a range of pressure and temperature conditions that mirror those expected to occur inside these giant gas planets.

Giant Planets Found in the Stellar Suburbs
In the neighborhood that makes up our solar system, the giant planets-Jupiter and Saturn-reside in the chilly outer regions, while smaller planets tend to orbit closer to the sun. Our planet Earth lives in an intermediate tropical zone well-suited to life. Planet hunters have long wondered: Is this same type of planetary configuration common around other stars throughout our galaxy or are we unique? The best way to find out is to do a census of the planetary denizens of the galaxy.

The Universe is hotter than expected
The Universe is hotter than expected
Researchers at the University of Geneva have succeeded in reconciling cosmological theory and observations of the Universe by considering that it is hotter than previously thought. Astrophysicists still encounter various inconsistencies between cosmological theory and measurements made with various research instruments.

Milky Way no freak accident, astronomers say
Milky Way no freak accident, astronomers say
Detailed study by University of Sydney astronomers of a galaxy 320 million light years away reveals striking similarities to our own home. The first detailed cross-section of a galaxy broadly similar to the Milky Way, published today , reveals that our galaxy evolved gradually, instead of being the result of a violent mash-up.

An inconstant Hubble constant? U-M research suggests fix to cosmological cornerstone
An inconstant Hubble constant? U-M research suggests fix to cosmological cornerstone
More than 90 years ago, astronomer Edwin Hubble observed the first hint of the rate at which the universe expands, called the Hubble constant. Almost immediately, astronomers began arguing about the actual value of this constant, and over time, realized that there was a discrepancy in this number between early universe observations and late universe observations.

Imaging technique could help identify where landslides are likely
Each year, landslides kill thousands of people around the world and cause catastrophic property damage. But scientists are still trying to better understand the circumstances that cause them. Doing so would go a long way toward helping people predict where landslides could occur and how severe they might be.

Dating the stars - scientist provide most accurate picture yet
Dating the stars - scientist provide most accurate picture yet
Scientists have succeeded in dating some of the oldest stars in our galaxy with unprecedented precision by combining data from the stars' oscillations with information about their chemical composition. The team led by researchers at the University of Birmingham, surveyed around a hundred red giant stars, and were able to determine that some of these were originally part of a satellite galaxy called Gaia-Enceladus, which collided with the Milky Way early in its history.

Scientists hunt for evidence of 'lensed' gravitational waves
Scientists hunt for evidence of ’lensed’ gravitational waves
Scientists searching for evidence of lensed gravitational waves have published new research outlining the most recent findings on their quest for the first detection of these elusive signals. Gravitational lensing has been predicted by Einstein himself, and observed by scientists for decades: light emitted by distant objects in the Universe is bent by the gravitational pull of very massive galaxies, as they cross the line-of-sight of the light source.
