A new approach for solving the dark energy mystery
What is behind dark energy - and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open questions of physics. The universe has a number of bizarre properties that are difficult to understand with everyday experience.

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.

Satellite Data Shows Sustained Severe Drought in Europe
Satellite Data Shows Sustained Severe Drought in Europe
By Falko Schoklitsch Europe lacks groundwater - a lot of groundwater. The continent has already been suffering from a severe drought since 2018. This is confirmed by satellite data analysed at the Institute of Geodesy at TU Graz. Europe has been experiencing a severe drought for years. Across the continent, groundwater levels have been consistently low since 2018, even if extreme weather events with flooding temporarily give a different picture.

A new model for dark matter
Phase transition in early universe changes strength of interaction between dark and normal matter This NASA Hubble Space Telescope image shows the distribution of dark matter in the center of the giant galaxy cluster Abell 1689, containing about 1,000 galaxies and trillions of stars. Dark matter is an invisible form of matter that accounts for most of the universe's mass.

A new model for dark matter
PRESS AND PUBLIC RELATIONS Phase transition in the early universe changes strength of interaction between dark and normal matter Dark matter remains one of the greatest mysteries of modern physics. It is clear that it must exist, because without dark matter, for example, the motion of galaxies cannot be explained.

James Webb Space Telescope identifies origins of icy building blocks of life
Interstellar molecular clouds are considered to be the birth sites of planetary systems. With the help of the James Webb Space Telescope, an international research team including the Center for Space and Habitability (CSH) at the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS discovered the deepest and coldest ice ever detected in such a molecular cloud.

NASA Measures Underground Water Flowing From Sierra to Central Valley
NASA Measures Underground Water Flowing From Sierra to Central Valley
This source accounts for about 10% of all the water that enters this highly productive farmland, including rivers and rain. In a recent study , scientists found that a previously unmeasured source - water percolating through soil and fractured rock below California's Sierra Nevada mountains - delivers an average of 4 million acre feet (5 cubic kilometers) of water to the state's Central Valley each year.

Water modified ancient asteroid
Water modified ancient asteroid
Samples from asteroid Ryugu returned by the Hayabusa2 mission contain evidence of extensive alteration by water and appear related to CI chondrites, which are believed to best represent the bulk of the solar system composition. Lawrence Livermore National Laboratory (LLNL) scientists in collaboration with an international team looked at the isotopic composition of oxygen, carbon and manganese-chromium in two Ryugu particles to help determine the source of the water and timing of the chemical reactions occurring during the alteration processes.

How was the solar system formed? The Ryugu asteroid is helping us learn
Science + Technology UCLA scientists reveal that minerals from the asteroid were produced through reactions with water more than 4.5 billion years ago Previous analyses of ancient meteorites have shown that minerals were created through chemical reactions with water as far back as 4.5 billion years ago.

Mission to Antarctica: discovery of a 7.6 kg meteorite
After spending the holidays in Antarctica, an international research team led by Vinciane Debaille - G-Time Laboratory, Free University of Brussels - has returned from its mission with a lot of meteorites.

Tumultuous migration on the edge of the Hot Neptune Desert
Tumultuous migration on the edge of the Hot Neptune Desert
A team from the University of Geneva reveals the eventful migration history of planets bordering the Hot Neptune Desert, these extrasolar planets that orbit very close to their star. All kinds of exoplanets orbit very close to their star. Some look like the Earth, others like Jupiter. Very few, however, are similar to Neptune.

Astronomers capture radio signal from distant galaxy
Astronomers capture radio signal from distant galaxy
How do stars form in distant galaxies? Astronomers have long been trying to answer this question by detecting radio signals emitted by nearby galaxies. However, these signals become weaker the further away a galaxy is from Earth, making it difficult for current radio telescopes to pick up. Now researchers from Montreal and India have captured a radio signal from the most distant galaxy so far at a specific wavelength known as the 21 cm line, allowing astronomers to peer into the secrets of the early universe.

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.

How Do Rocky Planets Really Form?
Scientists unveil a unified theory for rocky planet formation A new theory for how rocky planets form could explain the origin of so-called "super-Earths"-a class of exoplanets a few times more massive than the Earth that are the most abundant type of planet in the galaxy. Further, it could explain why super-Earths within a single planetary system often wind up looking strangely similar in size, as though each system were only capable of producing a single kind of planet.

New Results Reveal Surprising Behavior of Minerals Deep in the Earth
As you are reading this, more than 400 miles below you is a massive world of extreme temperatures and pressures that has been churning and evolving for longer than humans have been on the planet. Now, a detailed new model from Caltech researchers illustrates the surprising behavior of minerals deep in the planet's interior over millions of years and shows that the processes are actually happening in a manner completely opposite to what had been previously theorized.

Old and new stars paint very different pictures of the Triangulum galaxy
Astronomers have been gazing at the Triangulum galaxy for centuries. But they-ve never seen it quite like this. On Jan. 11 at the 241st meeting of the American Astronomical Society in Seattle, a team led by scientists at the University of Washington and the Center for Computational Astrophysics unveiled results using the Panchromatic Hubble Andromeda Treasury Triangulum Extended Region - or PHATTER - survey.

NASA Wants You to Help Study Planets Around Other Stars
NASA Wants You to Help Study Planets Around Other Stars
The Exoplanet Watch project invites you to use your smartphone or personal telescope to help track worlds outside our solar system. More than 5,000 planets have been confirmed to exist outside our solar system, featuring a wide array of characteristics like clouds made of glass and twin suns. Scientists estimate there could be millions more exoplanets in our home galaxy alone, which means professional astronomers could use your help tracking and studying them.

Eight new super-hot stars
Eight new super-hot stars
An international team of astronomers has discovered eight of the hottest stars in the universe, all with surfaces hotter than 100,000 degrees Celsius. The work was published in Monthly Notices of the Royal Astronomical Society. The paper is based on data gathered using the Southern African Large Telescope (SALT), the largest single optical telescope in the southern hemisphere, with a 10m x 11m mirror.
