Dark matter is slowing the spin of the Milky Way's galactic bar
Dark matter is slowing the spin of the Milky Way’s galactic bar
The spin of the Milky Way's galactic bar, which is made up of billions of clustered stars, has slowed by about a quarter since its formation, according to a new study by UCL and University of Oxford researchers. For 30 years, astrophysicists have predicted such a slowdown, but this is the first time it has been measured.

Astronomers spot a 'blinking giant' near the centre of the Galaxy
Astronomers spot a ’blinking giant’ near the centre of the Galaxy
Astronomers have spotted a giant 'blinking' star towards the centre of the Milky Way, more than 25,000 light years away. There are certainly more to be found, but the challenge now is in figuring out what the hidden companions are, and how they came to be surrounded by discs, despite orbiting so far from the giant star Leigh Smith An international team of astronomers observed the star, VVV-WIT-08, decreasing in brightness by a factor of 30, so that it nearly disappeared from the sky.

French ESA astronaut Thomas Pesquet to continue experiments on foams
French ESA astronaut Thomas Pesquet to continue experiments on foams
Studying how liquid foams evolve over time is difficult, if not impossible, on Earth because of gravity. The FOAM-C experiment, which began in 2020, was designed to study liquid foams in zero gravity on board the ISS. New samples will be set up by French astronaut Thomas Pesquet on Friday, June 11. The FOAM-C experiment studies the properties of liquid foams in zero gravity.

Over 500 new FRBs detected in single year due to CHIME telescope
Fast radio bursts, or FRBs, blaze for a few milliseconds before vanishing without a trace. Their origins are unknown, and their appearance is unpredictable. In the decade following their discovery in 2007, only 140 FRBs had been seen. Now, thanks to the launch of a large stationary telescope in the interior of British Columbia in 2018, the number of new FRBs detected has almost quadrupled - for a total of 535.

CIBER-2 Takes Its First Flight
The Cosmic Infrared Background Experiment-2 (CIBER-2) took its first flight late on June 6 Pacific Time, soaring into space for a short time aboard a NASA rocket. The experiment is measuring a mysterious glow of infrared light that fills our skies called the cosmic infrared background. The origins of CIBER go back to 2007, when NASA's Spitzer Space Telescope made measurements of the cosmic infrared background, which appears as a splotchy pattern on the sky.

Astronomers apply their skills to cancer research
Astronomers apply their skills to cancer research
You might not think that studying the universe could benefit research into serious illnesses like cancer, but Durham's astronomers have joined forces with cancer researchers to improve the diagnosis and treatment of patients. We're working with the NHS, healthcare researchers and biotech experts on the £1million CUP-COMP project to improve outcomes for people with cancer of unknown primary (CUP).

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.

Looking deep into the universe
Looking deep into the universe
How is matter distributed within our universe? And what is the mysterious substance known as dark energy made of? HIRAX, a new large telescope array comprising hundreds of small radio telescopes, should provide some answers. Among those instrumental in developing the system are physicists from ETH Zurich.

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.

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.
