Dance of electrons measured in the glow from exploding neutron-stars
The temperature of elementary particles has been observed in the radioactive glow following the collision of two neutron stars and the birth of a black hole. This has, for the first time, made it...
View ArticleSpace: A new frontier for exploring stem cell therapy
Stem cells grown in microgravity aboard the International Space Station (ISS) have unique qualities that could one day help accelerate new biotherapies and heal complex disease, researchers say. The...
View ArticleAsteroid grains shed light on the outer solar system's origins
Tiny grains from asteroid Ryugu are revealing clues to the magnetic forces that shaped the far reaches of the solar system over 4.6 billion years ago. The findings suggest the distal solar system...
View ArticleInterstellar methane as progenitor of amino acids?
Gamma radiation can convert methane into a wide variety of products at room temperature, including hydrocarbons, oxygen-containing molecules, and amino acids, reports a research team. This type of...
View ArticleOff-the-shelf thermoelectric generators can upgrade CO2 into chemicals: The...
Readily available thermoelectric generators operating under modest temperature differences can power CO2 conversion, according to a proof-of-concept study by chemists. The findings open up the...
View ArticleAstrophysicists use echoes of light to illuminate black holes
Researchers have developed an innovative technique to search for black hole light echoes. Their novel method, which will make it easier for the mass and the spin of black holes to be measured,...
View ArticleEinstein's equations collide with the mysteries of the Universe
Why is the expansion of our Universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental...
View ArticleSwirling polar vortices likely exist on the Sun
Like the Earth, the Sun likely has swirling polar vortices, according to new research. But unlike on Earth, the formation and evolution of these vortices are driven by magnetic fields.
View ArticleNew solar composition ratios that could reconcile longstanding questions
A team combined compositional data of primitive bodies like Kuiper Belt objects, asteroids and comets with new solar data sets to develop a revised solar composition that potentially reconciles...
View ArticleAstronomers' theory of how galaxies formed may be upended
The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming...
View ArticleThree galactic 'red monsters' in the early Universe
Astronomers have identified three ultra-massive galaxies -- nearly as massive as the Milky Way -- already in place within the first billion years after the Big Bang. This surprising discovery was made...
View ArticleGas-churning monster black holes
Scientists using observations from NASA's Neil Gehrels Swift Observatory have discovered, for the first time, the signal from a pair of monster black holes disrupting a cloud of gas in the center of a...
View ArticleMeteorite contains evidence of liquid water on Mars 742 million years ago
An asteroid struck Mars 11 million years ago and sent pieces of the red planet hurtling through space. One of these chunks of Mars eventually crashed into the Earth and is one of the few meteorites...
View ArticleScientists compile library for evaluating exoplanet water
By probing chemical processes observed in the Earth's hot mantle, scientists have started developing a library of basalt-based spectral signatures that not only will help reveal the composition of...
View ArticleNew research explores volcanic caves, advancing the search for life on Mars
Through the intricate study of lava tubes -- caves formed following volcanic eruptions when lava cools down -- an international team of researchers has uncovered clues about Earth's ancient...
View ArticleConfinement may affect how we smell and feel about food
New research found confined and isolating environments changed the way people smelled and responded emotionally to certain food aromas. The team in this study compared 44 people's emotional responses...
View ArticleAstronomers discover first pairs of white dwarf and main sequence stars in...
Astronomers have discovered the first pairs of white dwarf and main sequence stars -- 'dead' remnants and 'living' stars -- in young star clusters. This breakthrough offers new insights on an extreme...
View ArticleResearch on gravity in line with Einstein's theory of general relativity
Researchers used the Dark Energy Spectroscopic Instrument to map how nearly 6 million galaxies cluster across 11 billion years of cosmic history. Their observations line up with what Einstein's theory...
View ArticleAstronomers take the first close-up picture of a star outside our galaxy
While astronomers have taken about two dozen zoomed-in images of stars in our galaxy, unveiling their properties, countless other stars dwell within other galaxies, so far away that observing even one...
View ArticleA nearby supernova could end the search for dark matter
Axions are the most likely candidate for enigmatic dark matter that dominates the universe. Astrophysicists are searching for evidence of high-mass axions produced during supernovae. Scientists propose...
