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.

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.

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.

TESS dates an ancient collision with our galaxy
TESS dates an ancient collision with our galaxy
A single bright star in the constellation of Indus, visible from the southern hemisphere, has revealed new insights on an ancient collision that our galaxy the Milky Way underwent with another smaller galaxy called Gaia-Enceladus early in its history. An international team of scientists led by the University of Birmingham adopted the novel approach of applying the forensic characterisation of a single ancient, bright star called ν Indi as a probe of the history of the Milky Way.

How heavy is Dark Matter? Scientists radically narrow the potential mass range for the first time
How heavy is Dark Matter? Scientists radically narrow the potential mass range for the first time
Scientists have calculated the mass range for Dark Matter - and it's tighter than the science world thought. Their findings - due to be published in Physical Letters B in March - radically narrow the range of potential masses for Dark Matter particles, and help to focus the search for future Dark Matter-hunters.
