Supercomputer simulations unlock space weather puzzle
Scientists have long questioned why the bursts of hot gas from the Sun do not cool down as fast as expected, and now a UCL-led team of researchers have used a supercomputer to find out why. The team will now compare their simulations with 'real' data from the European Space Agency's flagship Solar Orbiter mission, with the hope that it will confirm their predictions and provide a conclusive answer.

Detector Technology Developed at Berkeley Lab Yields Unprecedented 3D Images, Heralding Far Larger Application to Study Neutrinos
Detector Technology Developed at Berkeley Lab Yields Unprecedented 3D Images, Heralding Far Larger Application to Study Neutrinos
By Bill Schulz An experiment to capture unprecedented 3D images of the trajectories of charged particles has been demonstrated using cosmic rays as they strike and travel through a cryostat filled with a ton of liquid argon. The results confirm the capabilities of a novel detector technology for particle physics developed by researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) in collaboration with several university and industrial partners.

Furthering the exploration of space
Furthering the exploration of space
Durham's researchers are helping to build some of the world's most powerful new telescopes to further our exploration of space. Our astronomers and cosmologists are also involved major international projects that will hunt two of the universe's most mysterious ingredients - dark matter and dark energy - and investigate how the universe formed.

Building a universe in a supercomputer
Building a universe in a supercomputer
You can't physically crash a planet into another planet in a lab to see what happens or look quite far enough back in time to see how the universe might have formed. So what do you do? At Durham we use supercomputer technology to simulate the universe as we seek to unravel its mysteries. How do galaxies form? What are dark matter and dark energy? And what will be the ultimate fate of the universe? COSMA supercomputer The COSMA supercomputer - with the memory of about 25,000 high-powered laptops - allows researchers to answer these big cosmological questions.

Impacting life on Earth
Our Astronomy and Cosmology research is having an impact on life here on Earth. Our researchers are using their skills to help newborn babies, stop the spread of Covid-19 and protect coffee plants. Newborn babies Drawing on their experience of dealing with huge amounts of astronomical data, our researchers have worked with the NHS to establish the standard for recognising vital signs in healthy newborn babies.

Discovery of methanol in a 'warm' planet-forming disk
Discovery of methanol in a ’warm’ planet-forming disk
Astronomers have identified the molecule methanol in the 'warm zones' of a protoplanetary disk circling a star about 360 light years from Earth. The finding is significant because although methanol - CH3OH - is one of the simpler complex carbon-based molecules, it is a precursor chemical involved in the creation of more complex substances such as amino acids and proteins, the building blocks of life.

The Symmetry Between Electrons and Muons Looks ’Shaky’
Experimental hints of possible new physical phenomena beyond the Standard Model Using data acquired on the worldwide biggest and strongest particle accelerator, the Large Hadron Collider (LHC) at the CERN European particle physics laboratory in Geneva (Switzerland), scientists involved in the LHCb experiment have found hints of possible new physical phenomena.

Supernovae Twins Open Up New Possibilities for Precision Cosmology
Supernovae Twins Open Up New Possibilities for Precision Cosmology
By Bob Cahn Cosmologists have found a way to double the accuracy of measuring distances to supernova explosions - one of their tried-and-true tools for studying the mysterious dark energy that is making the universe expand faster and faster. The results from the Nearby Supernova Factory (SNfactory) collaboration, led by Greg Aldering of the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), will enable scientists to study dark energy with greatly improved precision and accuracy, and provide a powerful crosscheck of the technique across vast distances and time.

FASER is born: new experiment will study particles that interact with dark matter
FASER is born: new experiment will study particles that interact with dark matter
The newest experiment at CERN, the European Organization for Nuclear Research, is now in place at the Large Hadron Collider in Geneva. FASER , or F orw a rd S earch E xpe r iment, was approved by CERN's research board in March 2019. Now installed in the LHC tunnel, this experiment, which seeks to understand particles that scientists believe may interact with dark matter, is undergoing tests before data collection commences next year.

6000 hours of research to hear gravitational waves
6000 hours of research to hear gravitational waves
Remember the days before working from home? It's Monday morning, you're running late to beat the traffic, and you can't find your car keys. What do you do? You might try moving from room to room, casting your eye over every flat surface, in the hope of spotting the missing keys. Of course, this assumes they are somewhere in plain sight; if they're hidden under a newspaper, or fallen behind the sofa, you'll never spot them.

’Campfires’ offer clue to solar heating mystery
Miniature solar flares nicknamed "campfires", recently discovered near the surface of the Sun, are about 1,000 to 5,000 km tall and between 1-1.5 million degrees hot, finds a new study co-authored by UCL researchers. The study compared data from Solar Orbiter, the Sun-observing mission by ESA and NASA, with observations from NASA's Solar Dynamics Observatory to triangulate the height of the campfires.

How long is a day on Venus’ Scientists crack mysteries of our closest neighbor
Venus is an enigma. It's the planet next door and yet reveals little about itself. An opaque blanket of clouds smothers a harsh landscape pelted by acid rain and baked at temperatures that can liquify lead. Now, new observations from the safety of Earth are lifting the veil on some of Venus' most basic properties.

Black hole-neutron star collisions may settle dispute over Universe’s expansion
Studying the violent collisions of black holes and neutron stars may soon provide a new measurement of the Universe's expansion rate, helping to resolve a long-standing dispute, suggests a new simulation study led by researchers at UCL. Our two current best ways of estimating the Universe's rate of expansion - measuring the brightness and speed of pulsating and exploding stars, and looking at fluctuations in radiation from the early Universe - give very different answers, suggesting our theory of the Universe may be wrong.

Icy clouds could have kept early Mars warm enough for rivers and lakes
Simulation led by UChicago geoscientist finds missing piece to Martian climate puzzle One of the great puzzles of modern space science is neatly summed up by the view from NASA's Perseverance, which just landed on Mars: Today it's a desert planet, and yet the rover is sitting right next to an ancient river delta.

Durham among first to use Hubble successor
Durham's astronomers are playing a key role in the biggest scientific programme to be carried out on the new successor to the Hubble Space Telescope. Our scientists will use NASA's James Webb Space Telescope (JWST) to hunt for dark matter and investigate early galaxy formation. The JWST is the largest, most powerful space telescope ever built and is scheduled for launch in October 2021 before beginning operations in 2022.
