Spain gears up for August total solar eclipse

Spain, one of the few places in the world where a total solar eclipse will be visible in August, has begun preparations for an event it hopes will shift tourism away from the beaches and toward the countryside.

Researchers uncover chemical origins of the Perseus cluster of galaxies

An international team of researchers has developed new stellar and supernova models to explain the mysterious elemental abundance patterns left by billions of supernova explosions around the Perseus constellation, which have been difficult to explain with conventional theoretical models, reports three recent studies published in The Astrophysical Journal.

Q&A: Is it time to expand our thinking about dark matter? A new study says yes

We may be more in the dark about dark matter than previously thought, according to a new analysis of distant galaxy clusters. Yale astrophysicist Priyamvada Natarajan, a leading theorist on the nature of black holes and dark matter, says new observational data conflicts with certain assumptions about cold dark matter (CDM)—unseen, slow-moving particles that are […]

Webb discovers one of the universe’s first galaxies

Scientists have discovered a galaxy as it was 13 billion years ago, 800 million years after the Big Bang. It contains possible evidence of the universe’s first stars and is one of the most chemically primitive galaxies observed to date.

Will future missions to the moon be sustainable? It may depend on whom you ask

There’s a new space race to the moon, and this time the ambitions are not just to visit but to stay. NASA’s Artemis program aims to establish a long-term human presence on the lunar surface in the 2030s. China, India, Japan and a number of private companies all have lunar mission programs of their own. […]

Astrophysicists use ‘space archaeology’ to trace the history of a spiral galaxy

Billions of years ago, a young spiral galaxy began to grow in a crowded part of the universe. It pulled in gas and small companion galaxies, slowly building up the bright central region and sweeping spiral arms we see today.

Wristwatch-like device enables assessment of health risks for astronauts on mission to the moon

Just a few hours before the Orion spacecraft crossed the sky en route to the moon on April 1, mechatronics engineer Rodrigo Trevisan Okamoto received confirmation he had been waiting for since the Artemis 2 mission was announced in 2023. The email from NASA stated that the crew of the first crewed mission to orbit […]

New UFO files offer no answers—but something is happening in the skies

The US Government has released a new trove of documents on cases of “unidentified anomalous phenomena” (UAPs)—many of which would have been described in the past as unidentified flying objects or UFOs—including photos, videos and reports of unexplained events sighted in the sky and in space.

Statistical technique could uncover secrets of ‘ringing’ black holes

Researchers have developed a technique to analyze how black holes “ring” when they collide and merge: one of the universe’s most dramatic events. When black holes merge, the collision produces a new, larger black hole that “rings” like a plucked guitar string or a bell while it settles into its final, stable shape. But instead […]

A twinkling pulsar reveals invisible structures in space

The twinkling stars in the night sky are not just beautiful to look at. Their flickering reveals something about the varying temperatures and densities in the layers of Earth’s atmosphere, which refract the light as it travels toward us. Certain stellar remnants that emit radio waves can exhibit a very similar effect.

TESS reveals fullest night-sky map yet, with nearly 6,000 exoplanet worlds

NASA’s TESS (Transiting Exoplanet Survey Satellite) has released its most complete view of the starry sky to date, filling in gaps from previous observations. Nearly 6,000 colored dots scattered across the image show the locations of either confirmed or candidate exoplanets—worlds beyond our solar system—identified by the mission as of September 2025 at the end […]

Astronomers directly detect how turbulence between stars distorts light

Astronomers led by the Center for Astrophysics | Harvard & Smithsonian (CfA) have made the first direct detection of turbulence distorting light in the interstellar medium. The findings will help scientists achieve clearer imaging of the supermassive black hole at the center of the Milky Way galaxy.

Waterworn chaos on Mars stretches the length of Italy

This month, ESA’s Mars Express takes us to Shalbatana Vallis: a fascinating Martian valley surrounded by signs of water, lava, craters and chaos. Shalbatana Vallis is an impressive channel near Mars’s equator. This image, taken by Mars Express’s High Resolution Stereo Camera (HRSC), captures the northern part of the channel, which weaves its way across […]

Dual spacecraft capture both hemispheres of interstellar comet 3I/ATLAS at once

The Southwest Research Institute-led Ultraviolet Spectrograph (UVS) instruments aboard ESA’s Jupiter Icy Moons Explorer (Juice) spacecraft and NASA’s Europa Clipper made unique observations of interstellar comet 3I/ATLAS in late 2025. SwRI leads the UVS instruments on both spacecraft, simultaneously imaging both hemispheres of the comet and detecting the comet’s ultraviolet emissions.
