Novel way to 'see' the first stars through the fog of the early Universe
Novel way to ’see’ the first stars through the fog of the early Universe
A team of astronomers has developed a method that will allow them to -see- through the fog of the early Universe and detect light from the first stars and galaxies. The first stars were surrounded by clouds of hydrogen, which absorb light really well, so it's hard to detect or observe the light behind the clouds directly.

Cyborg collaboration finds 40,000 ring galaxies
Cyborg collaboration finds 40,000 ring galaxies
Human and machine intelligence worked together to find 40,000 ring galaxies, scientists at the National Astronomy Meeting will announce today. Dr Mike Walmsley of The University of Manchester will present the new work, describing how this "cyborg" approach measured the shapes of millions of galaxies.

New radio astronomy survey peers through cosmic dust to investigate the Milky Way
New radio astronomy survey peers through cosmic dust to investigate the Milky Way
The first results from a mammoth astronomy project aimed at mapping out the origins of our 13.8 billion year old universe have been announced today. An international team of astronomers from around the globe taking part in the project named, COMAP (CO Mapping Array Project) will offer us a new glimpse into this epoch of galaxy assembly, helping to answer questions about what really caused the universe ' s rapid increase in the production of stars.

World's largest and most sensitive dark matter detector comes to life
World’s largest and most sensitive dark matter detector comes to life
The world's most sensitive dark matter experiment has gathered its first result, moving us a step closer to understanding one of the biggest mysteries of the Universe. It shows the experiment is successfully operating after years of set up by a team involving UCL researchers. The international project "LUX-ZEPLIN Dark Matter Experiment (LZ)" based at the Sanford Underground Research Facility in South Dakota, US is intricately and innovatively designed to find direct evidence of dark matter - an invisible substance thought to make up most of the mass of the Universe.

Slow spin of early galaxy observed for the first time
Slow spin of early galaxy observed for the first time
One of the most distant known galaxies, observed in the very earliest years of the Universe, appears to be rotating at less than a quarter of the speed of the Milky Way today, according to a new study involving University of Cambridge researchers. For the study, published in The Astrophysical Journal Letters , an international team of researchers analysed data from a galaxy known as MACS1149-JD1 (JD1), obtained from observations by the Atacama Large Millimeter/submillimeter Array (ALMA), an assembly of radio telescopes in Chile.

Chandra Observatory shows black hole spins slower than its peers
Chandra Observatory shows black hole spins slower than its peers
Astronomers have made a record-breaking measurement of a black hole's spin, one of two fundamental properties of black holes. NASA's Chandra X-ray Observatory shows this black hole is spinning slower than most of its smaller cousins. This is the most massive black hole with an accurate spin measurement and gives hints about how some of the universe's biggest black holes grow.

Powerful Tonga volcano eruption triggered atmospheric gravity waves reaching the edge of space
Powerful Tonga volcano eruption triggered atmospheric gravity waves reaching the edge of space
Hunga Tonga-Hunga Ha-apai eruption in January was unique in observed science, creating waves that reverberated around Earth, reaching 100km into the ionosphere. The eruption of the Hunga Tonga-Hunga Ha-apai submarine volcano on 15 January 2022 was one of the most explosive volcanic events of the modern era, a new study has confirmed.

Climate damage caused by growing space tourism needs urgent mitigation
Climate damage caused by growing space tourism needs urgent mitigation
A formidable space tourism industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL. Published today in the journal  Earth's Future , researchers from UCL, the University of Cambridge and Massachusetts Institute of Technology (MIT) used a 3D model to explore the impact of rocket launches and re-entry in 2019, and the impact of projected space tourism scenarios based on the recent billionaire space race.

Astronomers link 64 telescopes to observe the structure of the Universe ahead of the SKAO launch
Astronomers link 64 telescopes to observe the structure of the Universe ahead of the SKAO launch
An international team of astronomers have for the first time combined the power of 64 radio telescope dishes to detect the faint signatures of neutral hydrogen gas across cosmological scales. The feat was achieved using the South African-based MeerKAT telescope, a precursor to the world's largest radio observatory, the SKA Observatory (SKAO), which will probe the Universe in unprecedented detail.

Galaxies form through mergers
Galaxies form through mergers
Examples of galaxy pairs found in this study - here are examples of detected systems which are within close proximity to each other Credit- C.Mundy C.Conselice et al Astronomers in the UK announce today that have established how galaxies like our own Milky Way formed over 10 billion years of cosmic time through an abundance of separate galaxies colliding together.

No signs (yet) of life on Venus
No signs (yet) of life on Venus
The unusual behaviour of sulphur in Venus- atmosphere cannot be explained by an -aerial- form of extra-terrestrial life, according to a new study. Even if -our- Venus is dead, it-s possible that Venus-like planets in other systems could host life Paul Rimmer Researchers from the University of Cambridge used a combination of biochemistry and atmospheric chemistry to test the -life in the clouds- hypothesis, which astronomers have speculated about for decades, and found that life cannot explain the composition of the Venusian atmosphere.

Largest chemical map of the Milky Way unveiled
Largest chemical map of the Milky Way unveiled
The European Space Agency's Gaia mission involving UCL researchers has released a new treasure trove of data about our home galaxy, including the largest chemical map ever produced and the full 3D motions of 35 million stars. Gaia is ESA's mission to create the most accurate and complete multi-dimensional map of the Milky Way.

Scientists explain why Uranus and Neptune are different colours
Scientists explain why Uranus and Neptune are different colours
Layers of haze particles are responsible for the different blue hues of the ice giants Neptune and Uranus. Neptune and Uranus have much in common - they have similar masses, sizes, and atmospheric compositions - yet Neptune looks distinctly bluer than its planetary neighbour Uranus. New research led by Professor Patrick Irwin, Department of Physics , University of Oxford suggests that a layer of haze that exists on both planets is behind the different hues of blue.

First image of black hole at centre of our galaxy
The first image of the supermassive black hole at the centre of our own Milky Way galaxy has been produced by a global team involving UCL researcher Dr Ziri Younsi. The result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the centre of most galaxies.
