Lightest black hole or heaviest neutron star? Manchester astronomers uncover a mysterious object in Milky Way
An artist's impression of the system assuming that the massive companion star is a black hole. The brightest background star is its orbital companion, the radio pulsar PSR J0514-4002E. The two stars are separated by 8 million km and circle each other every 7 days. An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.

Galaxy mergers solve early Universe mystery
Galaxy mergers solve early Universe mystery
A team of astronomers, led by the University of Cambridge, has used the NASA/ESA/CSA James Webb Space Telescope to reveal, for the first time, what lies in the local environment of galaxies in the very early Universe. This has solved one of the most puzzling mysteries in astronomy - why astronomers detect light from hydrogen atoms that should have been entirely blocked by the pristine gas that formed after the Big Bang.

Astronomers detect oldest black hole ever observed
Astronomers detect oldest black hole ever observed
Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to death. It's a new era: the giant leap in sensitivity, especially in the infrared, is like upgrading from Galileo's telescope to a modern telescope overnight Roberto Maiolino The international team, led by the University of Cambridge, used the NASA/ESA/CSA James Webb Space Telescope (JWST) to detect the black hole, which dates from 400 million years after the big bang, more than 13 billion years ago.

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
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.

Dark Energy Survey provides unprecedented detail on the expansion of the universe
A decade-long analysis of nearly 1,500 supernovae sheds new light on the mysterious dark energy that makes up around 70 per cent of the universe. Results from the Dark Energy Survey (DES) are consistent with the standard cosmological model of a universe that is expanding at an accelerating rate, but they hint at the exciting possibility that the density of dark energy may have varied over time.

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
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.

Six planets in synchronised 'dance' lasting a billion years
Six planets in synchronised ’dance’ lasting a billion years
An international collaboration involving UCL researchers has discovered six planets orbiting their central star in a rhythmic beat, a rare case of an "in sync" gravitational lockstep that could offer deep insight into planet formation and evolution. The findings, published in Nature , are particularly valuable as the planets are likely to have been performing this same rhythmic dance ever since the system formed more than a billion years ago.

’Bouncing’ comets could deliver building blocks for life to exoplanets
How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers from the University of Cambridge have shown how comets could deposit similar building blocks to other planets in the galaxy. It's possible that the molecules that led to life on Earth came from comets, so the same could be true for planets elsewhere in the galaxy Richard Anslow In order to deliver organic material, comets need to be travelling relatively slowly - at speeds below 15 kilometres per second.
