One of the biggest mysteries in science -- dark energy -- doesn't actually exist, according to researchers looking to solve the riddle of how the Universe is expanding. For the past 100 years, physicists have generally assumed that the cosmos is ...
Galaxy clusters -- the big cities of the universe -- are home to many giant elliptical galaxies that have completed their growth and are not forming stars. However, it is still unclear what has shut ...
After taking the first images of black holes, the groundbreaking Event Horizon Telescope (EHT) is poised to reveal how black holes launch powerful jets into space. Now, a research team has shown that ...
An international team of researchers has detected a binary star orbiting close to Sagittarius A*, the supermassive black hole at the centre of our galaxy. It is the first time a stellar pair has been found in the vicinity of a supermassive black ...

Dark ovals in Jupiter's polar haze, visible only at UV wavelengths, were first noticed 25 years ago, then ignored. A new study shows that these dark UV ovals are common, appearing at the south ...

Scientists have recently identified electrons and positrons with the highest energies ever recorded on Earth. They provide evidence of cosmic processes emitting colossal amounts of energy, the ...

A massive collision of galaxies sparked by one travelling at a scarcely-believable 2 million mph (3.2 million km/h) has been seen in unprecedented detail by one of Earth's most powerful ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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, ...

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 ...

Astronomers have discovered a supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang that is consuming matter at a phenomenal rate -- over 40 times the ...

Teams of astronomers used the combined power of NASA's Hubble and James Webb space telescopes to revisit the legendary Vega ...

For Halloween, the European Southern Observatory (ESO) reveals a spooktacular image of a dark nebula that creates the illusion of a wolf-like silhouette against a colourful cosmic backdrop. Fittingly ...

New research in our Milky Way has revealed a neutron star that rotates around its axis at an extremely high speed. It spins 716 times per second, making it one of the fastest-spinning objects ever ...

Researchers have strengthened the case that matter becomes dark energy when massive stars collapse and become black ...

Researchers have pored over more than two decades' worth of data from NASA's Chandra X-Ray Observatory to show there's new knotty science to discover around black ...

A distant interstellar cloud was found to contain an abundance of pyrene, a type of large carbon-containing molecules known as polycyclic aromatic hydrocarbons (PAHs). This suggest pyrene may have ...

A historical supernova documented by Chinese and Japanese astronomers in 1181 has been lost for centuries, until very recently. Yet, the newly found remnant shows some stunning characteristics that ...
