Researchers have discovered a potential 'cosmic glitch' in the universe's gravity, explaining its strange behavior on a cosmic scale.

A research team using the ChemCam instrument onboard NASA's Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were formed in a river, delta, or near the shoreline of an ancient lake.

NASA's James Webb Space Telescope has captured the sharpest infrared images to date of a zoomed-in portion of one of the most distinctive objects in our skies, the Horsehead Nebula. These observations show the top of the 'horse's mane' or edge of this iconic nebula in a whole new light, capturing the region's complexity with unprecedented spatial resolution.

Researchers have successfully used NASA's James Webb Space Telescope to map the weather on the hot gas-giant exoplanet WASP-43 b.

Computer simulations by astronomers support the idea that dark matter -- matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe -- exists, according to the researchers.

Astronomers have confirmed that differences in binary stars' composition can originate from chemical variations in the cloud of stellar material from which they formed. The results help explain why stars born from the same molecular cloud can possess different chemical composition and host different planetary systems, as well as pose challenges to current stellar and planet formation models.

Samples reveal evidence of changes experienced by the surface of asteroid Ryugu, some probably due to micrometeoroid bombardment.

Researchers co-led a study that will improve the detection of gravitational waves--ripples in space and time.

A new study has recovered a 3.7-billion-year-old record of Earth's magnetic field, and found that it appears remarkably similar to the field surrounding Earth today.

While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team realized that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.

Despite surface temperatures hot enough to melt lead, lava-spewing volcanoes, and puffy clouds of sulfuric acid, uninhabitable Venus offers vital lessons about the potential for life on other planets, a new paper argues.

Astronomers have produced the first high-resolution map of a massive explosion in a nearby galaxy, providing important clues on how the space between galaxies is polluted with chemical elements.

Based on radio telescope data and models of black hole physics, a team has used neural networks to reconstruct a 3D image that shows how explosive flare-ups in the disk of gas around our supermassive black hole might look.

Astronomers have discovered methane emission on a brown dwarf, an unexpected finding for such a cold and isolated world. The findings suggest that this brown dwarf might generate aurorae similar to those seen on our own planet as well as on Jupiter and Saturn.

Scientists have developed a new method using knot theory to find the optimal routes for future space missions without the need to waste fuel.

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce.

Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency's Gaia mission because it imposes an odd 'wobbling' motion on the companion star orbiting it. Astronomers have verified the mass of the black hole, putting it at an impressive 33 times that of the Sun.

The mystery of how Pluto got a giant heart-shaped feature on its surface has finally been solved by an international team of astrophysicists. The team is the first to successfully reproduce the unusual shape with numerical simulations, attributing it to a giant and slow oblique-angle impact.
