Astronomers create AI to better communicate their stellar research
An international team of scientists, led by a researcher at The University of Manchester , have developed a novel AI (artificial intelligence) approach to distil technical astronomy terminology into simple understandable English in their recent publication. new research is a result of the international RGZ EMU (Radio Galaxy Zoo EMU) collaboration and is transitioning radio astronomy language from specific terms, such as FRI (Fanaroff-Riley Type 1), to plain English terms such as "hourglass" or "traces host galaxy".

Jupiter icy moon explorer prepares to discover new worlds
Jupiter icy moon explorer prepares to discover new worlds
A Jupiter-exploring mission, which includes hardware provided by UCL scientists, is due to take off tomorrow (Thursday 13 April)m and will investigate whether some of the planet's icy moons are home to conditions that could support life. The European Space Agency's Jupiter Icy Moons Explorer (JUICE) will spend eight years travelling to the Jupiter system.

Small stars may host bigger planets than previously thought
Small stars may host bigger planets than previously thought
Stars with less than half the mass of our Sun are able to host giant Jupiter-style planets, in conflict with the most widely accepted theory of how such planets form, according to a new study led by UCL and University of Warwick researchers. Gas giants, like other planets, form from disks of material surrounding young stars.

Scientists have new tool to estimate how much water might be hidden beneath a planet's surface
Scientists have new tool to estimate how much water might be hidden beneath a planet’s surface
In the search for life elsewhere in the scientists have traditionally looked for planets with liquid water at their surface. But, rather than flowing as oceans and rivers, much of a planet's water can be locked in rocks deep within its interior. We wanted to investigate whether these planets, after such a tumultuous upbringing, could rehabilitate themselves and go on to host surface water Claire Guimond Scientists from the University of Cambridge now have a way to estimate how much water a rocky planet can store in its subterranean reservoirs.

Astronomers measure the heartbeat of spinning stars
Astronomers measure the heartbeat of spinning stars
An international team of scientist have used the MeerKAT radio telescope to observe the pulsing heartbeat of the universe as neutron stars are born and form swirling lightning storms which last for millions of years. Radio pulsars are spinning neutron stars from which we can observe flashes of radio waves in the manner of light pulses from a lighthouse.

First evidence that black holes are the source of dark energy
First evidence that black holes are the source of dark energy
Observations of supermassive black holes at the centres of galaxies point to a likely source of dark energy - the 'missing' 70% of the Universe. The measurements from ancient and dormant galaxies show black holes growing more than expected, aligning with a phenomenon predicted in Einstein's theory of gravity.

Meteorites reveal likely origin of Earth's volatile chemicals
Meteorites reveal likely origin of Earth’s volatile chemicals
Meteorites have told researchers the likely far-flung origin of Earth's volatile chemicals, some of which form the building blocks of life. They found that around half the Earth's inventory of the volatile element zinc came from asteroids originating in the outer Solar System - the part beyond the asteroid belt that includes the planets Jupiter , Saturn , and Uranus.

Space collaboration including Sussex scientist makes icy discovery which sheds light on the building blocks of life
In a development believed to shed light on the building blocks of life, an international team of scientists, including Prof Wendy Brown from the University of Sussex, has discovered diverse ices in the darkest, coldest regions of space so-far measured, which are around 500 light years from Earth. The discovery within a molecular cloud was made by scientists from the IceAge project, an international consortium of academics using the James Webb Space Telescope (JWST), to observe the building blocks of life.

Astronomical collaboration maps the structure of our Galaxy’s magnetic field
Almost a decade after starting observations of the sky in the northern hemisphere in the microwave range, the QUIJOTE Collaboration has presented the most accurate description we have of the polarisation of the emission of the Milky Way at these wavelengths. This is a window of observation not previously explored, which provides complementary information to that obtained previously by space mission (Planck and WMAP) dedicated to the study of the cosmic microwave background radiation (CMB), the fossil radiation left behind by the Big Bang.

'little hurricanes' to weigh and date planets around young stars
’little hurricanes’ to weigh and date planets around young stars
Little -hurricanes- that form in the discs of gas and dust around young stars can be used to study certain aspects of planet formation, even for smaller planets which orbit their star at large distances and are out of reach for most telescopes. It's extremely difficult to study smaller planets that are far away from their star by directly imaging them: it would be like trying to spot a firefly in front of a lighthouse.

How magnetic waves interact with Earth's bubble
How magnetic waves interact with Earth’s bubble
A new study involving UCL has uncovered how magnetic waves are transmitted past a standing shock wave, known as the bow shock, that forms ahead of Earth as a result of the solar wind hitting our magnetic bubble (magnetosphere). Shock waves occur in air when a plane travels faster than the speed of sound and also occur in plasma (a fourth state of matter that makes up 99% of the visible Universe) in space.

Mysteriously bright flash is a black hole jet pointing straight toward Earth, astronomers say
Mysteriously bright flash is a black hole jet pointing straight toward Earth, astronomers say
Astronomers have determined the source of an incredibly bright X-ray, optical and radio signal appearing from halfway across the Universe. The signal, named AT 2022cmc, was discovered earlier this year by the Zwicky Transient Facility in California. Findings published today in Nature Astronomy, suggest that it is likely from a jet of matter, streaking out from a supermassive black hole at close to the speed of light.

Non-detection of key signal allows astronomers to determine what the first galaxies were - and weren’t - like
Researchers have been able to make some key determinations about the first galaxies to exist, in one of the first astrophysical studies of the period in the early Universe when the first stars and galaxies formed, known as the cosmic dawn.

Shock waves trigger black holes' powerful jets
Shock waves trigger black holes’ powerful jets
Powerful jets of material released by black holes are accelerated far into space by shock waves within the jets, an international collaboration involving UCL researchers has found. The study, published in Nature , helps to solve a decades-old mystery about how these jets are produced. The research team was able to rule out alternative causes of the jets - such as magnetic reconnection - and, out of a number of theoretical models of how the particles in the jets are accelerated, showed that just one model was correct.

Worldwide dataset captures Earth in finest ever detail
A global open-source dataset of high-resolution images of Earth - the most extensive and detailed of its kind - has been developed by experts led by UCL with data from the European Space Agency (ESA). The free dataset, WorldStrat, will be presented at the NeurIPS 2022 conference in New Orleans. It includes nearly 10,000km² of free satellite images, showing every type of location, urban area and land use from agriculture, grasslands and forests to cities of every size and polar ice caps.
