New image of supermassive M87* black hole one year on
The global Event Horizon Telescope (EHT) collaboration involving UCL researcher Dr Ziri Younsi has released new images of M87*, the supermassive black hole at the centre of the galaxy Messier 87. The new images are from observations taken in April 2018, one year after the first observations of M87* in April 2017 which resulted in the first ever image of a black hole.

Experiment could test quantum nature of large masses for the first time
Experiment could test quantum nature of large masses for the first time
An experiment outlined by a UCL-led team of scientists from the UK and India could test whether relatively large masses have a quantum nature, resolving the question of whether quantum mechanical description works at a much larger scale than that of particles and atoms. Quantum theory is typically seen as describing nature at the tiniest scales and quantum effects have not been observed in a laboratory for objects more massive than about a quintillionth of a gram, or more precisely 10^(-20)g.

New research improves understanding of expansion of the Universe
The Dark Energy Survey (DES) collaboration involving UCL researchers has achieved one of the most robust measurements of the constraints on the universe's expansion to date. The international group of researchers, led by the U.S. Department of Energy's Fermi National Accelerator Laboratory (Fermilab), analysed nearly 1,500 supernovae using machine learning techniques.

Mesopotamian bricks unveil the strength of Earth's ancient magnetic field
Mesopotamian bricks unveil the strength of Earth’s ancient magnetic field
Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth's magnetic field 3,000 years ago, according to a new study involving UCL researchers. The research, published in the Proceedings of the National Academy of Sciences (PNAS) , describes how changes in the Earth's magnetic field imprinted on iron oxide grains within ancient clay bricks, and how scientists were able to reconstruct these changes from the names of the kings inscribed on the bricks.

Diamonds and rust help unveil 'impossible' quasi-particles
Diamonds and rust help unveil ’impossible’ quasi-particles
Researchers have discovered magnetic monopoles - isolated magnetic charges - in a material closely related to rust, a result that could be used to power greener and faster computing technologies. If monopoles did exist, and we were able to isolate them, it would be like finding a missing puzzle piece that was assumed to be lost Mete Atatüre Researchers led by the University of Cambridge used a technique known as diamond quantum sensing to observe swirling textures and faint magnetic signals on the surface of hematite, a type of iron oxide.

New theory seeks to unite Einstein's gravity with quantum mechanics
New theory seeks to unite Einstein’s gravity with quantum mechanics
A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime is announced today in two papers published simultaneously by UCL physicists. Modern physics is founded upon two pillars: quantum theory on the one hand, which governs the smallest particles in the universe, and Einstein's theory of general relativity on the other, which explains gravity through the bending of spacetime.

Interpreting the afterglow of a black hole's breakfast
Interpreting the afterglow of a black hole’s breakfast
An entirely new way to probe how active black holes behave when they eat has been discovered by an international team of astronomers. A sample of active black holes at the centre of 136 galaxies were found to shine in microwave and X-ray light in the same way, no matter their appetite for the surrounding galactic matter like clouds of gas and dust.

Extraordinary new space phenomenon mystifies scientists
Luminous fast blue optical transients are characterized by their intense blue light and are amongst the brightest known optical phenomena in the universe. They evolve rapidly, reaching peak brightness and fading again in a matter of days, unlike supernovae which take weeks or months. Image credit: NOIRLab/NSF/AURA/M.

Twisted magnets make brain-inspired computing more adaptable
Twisted magnets make brain-inspired computing more adaptable
A form of brain-inspired computing that exploits the intrinsic physical properties of a material to dramatically reduce energy use is now a step closer to reality, thanks to a new study led by UCL and Imperial College London researchers. Such an approach, known as physical reservoir computing, has until now been limited due to its lack of reconfigurability.

Euclid’s first images: the dazzling edge of darkness
The European Space Agency (ESA) mission Euclid, whose massive optical camera was built by an international team led by UCL researchers, has released its first full-colour images of the cosmos. This is the first time a telescope has been able to create such razor-sharp astronomical images across such a large patch of the sky, and looking so far into the distant Universe.

Graphene’s proton permeability: A switch for future energy technologies
"Understanding the connection between electronic and ion transport properties in electrode-electrolyte interfaces at the molecular scale could enable new strategies to accelerate processes central to many renewable energy technologies, including hydrogen generation and utilisation." Researchers from the National Graphene Institute at the University of Manchester have discovered a way to use light to accelerate proton transport through graphene , which could revolutionise the way we generate hydrogen.

What Guy Fawkes can teach us about the sky at night
With bonfire night on the horizon, scientists reveal just why fireworks are differently coloured and what this can teach us about stars in space. Elements commonly found in salts are used to make the colours in fireworks. The colours are caused when the elements are heated, causing them to release light in different colours, from bright blues to deep reds.

Infrared aurorae discovered at Uranus
Infrared aurorae discovered at Uranus
Planetary scientists including UCL's Professor Steve Miller have detected the infrared aurorae of the ice giant Uranus after searching for more than 30 years, in a new study published in Nature Astronomy. On Earth, the Northern and Southern Lights (aurorae) occur as a result of the interaction between the stream of charged particles known as the solar wind and our magnetic field, which funnels the particles in our atmosphere around the poles.

Black holes could come in 'perfect pairs' in an ever expanding Universe
Black holes could come in ’perfect pairs’ in an ever expanding Universe
Researchers from the University of Southampton, together with colleagues from the universities of Cambridge and Barcelona, have shown it's theoretically possible for black holes to exist in perfectly balanced pairs - held in equilibrium by a cosmological force - mimicking a single black hole. Black holes are massive astronomical objects that have such a strong gravitational pull that nothing, not even light, can escape.

Going rogue: Scientists apply giant wave mechanics on a nanometric scale
Researchers have shown how the principles of rogue waves - huge 30-metre waves that arise unexpectedly in the ocean - can be applied on a nano scale, with dozens of applications from medicine to manufacturing. Long considered to be a myth, rogue waves strike from comparably calm surroundings, smashing oil rigs and ships in their path.
