Particle’s ’wobble’ hints at new physics
The "wobble", or rate of precession, of the muon particle in a magnetic field is different from what our best theoretical model of the subatomic world would predict, according to an experiment involving UCL researchers that strengthens evidence for new, unknown physics. The Muon g-2 experiment, carried out at the Fermi National Accelerator Laboratory in the United States, measured with unprecedented precision the rate at which the muon "wobbled" (precessed) as it circulated a 15-metre magnetic ring at nearly the speed of light.

New image of magnetic fields at black hole's edge
New image of magnetic fields at black hole’s edge
A new image of the supermassive M87 black hole has been unveiled by the Event Horizon Telescope (EHT) collaboration involving UCL researchers, giving a closer look at how the black hole interacts with the matter surrounding it. The EHT team released the first image of a black hole in 2019, revealing a bright ring-like structure with a dark central region described as the black hole's shadow.

Analysis: How can some planets be hotter than stars?
PhD candidate Quentin Changeat and Dr Billy Edwards (both UCL Physics & Astronomy) explain how we examine the atmospheres of exoplanets (planets outside our solar system) as well as what the benefits of understanding these distant planets could be. Until the early 2000s, the only known planets were located in our own neighbourhood, the Solar System.

Experts recreate a mechanical Cosmos for the world’s first computer
Researchers at UCL have solved a major piece of the puzzle that makes up the ancient Greek astronomical calculator known as the Antikythera Mechanism, a hand-powered mechanical device that was used to predict astronomical events. Known to many as the world's first analogue computer, the Antikythera Mechanism is the most complex piece of engineering to have survived from the ancient world.

Hubble sees new atmosphere forming on a rocky exoplanet
Hubble sees new atmosphere forming on a rocky exoplanet
For the first time, scientists using the NASA/ESA Hubble Space Telescope have found evidence of volcanic activity reforming the atmosphere on a rocky planet around a distant star. The planet, GJ 1132 b, has a similar density, size, and age to Earth. It is a window onto the geology of another world Paul Rimmer The planet GJ 1132 b appears to have begun life as a gaseous world with a thick blanket of atmosphere.

UofG researchers aid in historic meteorite recovery
University of Glasgow researchers have played a key role in the first successful recovery of a meteorite on UK soil in nearly three decades. Dr Luke Daly, from the School of Geographical and Earth Sciences, was part of the international collaboration which tracked the entry of a fireball over Britain on Sunday 28 February.

Source of hazardous high-energy particles located in the Sun
The source of potentially hazardous solar particles, released from the Sun at high speed during storms in its outer atmosphere, has been located for the first time by researchers at UCL and George Mason University, Virginia, USA. These particles are highly charged and, if they reach Earth's atmosphere, can potentially disrupt satellites and electronic infrastructure, as well as pose a radiation risk to astronauts and people in airplanes.

Glaciers accelerate in the Getz region of West Antarctica
Glaciers accelerate in the Getz region of West Antarctica
Glaciers in West Antarctica are moving more quickly from land into the ocean, contributing to rising global sea levels. A 25-year record of satellite observations has been used to show widespread increases in ice speed across the Getz sector for the first time, with some ice accelerating into the ocean by nearly 50%.

Astronomers identify new method of planet formation
Astronomers identify new method of planet formation
Scientists have suggested a new explanation for the abundance in intermediate-mass exoplanets - a long-standing puzzle in astronomy. In the last 25 years, scientists have discovered over 4000 planets outside our solar system. From relatively small rock and water worlds to blisteringly hot gas giants, these planets display a remarkable variety.

Portrait of young galaxy throws theory of galaxy formation on its head
Scientists have challenged our current understanding of how galaxies form by unveiling pictures of a young galaxy in the early life of the Universe which appears surprisingly mature. The galaxy, dubbed ALESS 073.1, appears to have all of the features expected of a much more mature galaxy and has led the team of scientists to question how it grew so fast.

Global ice loss increases at record rate
Global ice loss increases at record rate
The rate at which ice is disappearing across the planet is speeding up, according to new research. And the findings also reveal that the Earth lost 28 trillion tonnes of ice between 1994 and 2017 – equivalent to a sheet of ice 100 metres thick covering the whole of the UK. The research is the first of its kind to carry out a survey of global ice loss using satellite data.

New galaxy sheds light on how stars form
Detailed observations of molecular gas in a tidal dwarf galaxy have important implications for our understanding of how stars are formed. Last updated on Sunday 31 January 2021 A lot is known about galaxies. We know, for instance, that the stars within them are shaped from a blend of old star dust and molecules suspended in gas.

Magnetic waves explain mystery of Sun’s outer layer
A theory as to why the Sun's outer atmosphere differs in its chemical make-up from its inner layers has been confirmed by direct observation for the first time by scientists at UCL and the Italian Space Agency. The Sun's extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades.

Survey of the sky maps 700 million astronomical objects
Scientists at UCL and from across the world have catalogued almost 700 million astronomical objects in one of the most detailed sky surveys ever undertaken. Scientists on the international Dark Energy Survey (DES), including those from eight UK institutions, have released the second set of data - mapping over an eighth of the entire sky using one of the most sensitive cameras ever built.

Quantum tech to help weigh universe’s most elusive particle
Researchers are leading a 3.8 million project to develop quantum technology aimed at detecting the mass of a neutrino, the universe's most abundant but elusive particle of matter. UCL is playing a key role in three of the seven projects. Neutrinos are millions of times lighter than electrons and are poorly understood as they can pass through matter undetected.

Scientists to lead hunt for dark matter
Cardiff University scientists are to lead a consortium hoping to track down one of the most mysterious materials in the Universe - dark matter. The 5m Quantum-Enhanced Interferometry (QI) collaboration will use state-of-the-art quantum technology to shed more light on the material which makes up roughly 27 per cent of the Universe but has yet to be directly detected.

Galaxy mergers could limit star formation
Our astronomers have looked nine billion years into the past to find evidence that galaxy mergers in the early universe could shut down star formation and affect galaxy growth. Using a powerful Earth-based telescope they saw that a huge amount of star-forming gas was ejected into the universe by the coming together of two galaxies.
