New research suggests the universe may not be perfectly uniform in every direction, as scientists have long believed. A puzzling mismatch known as the cosmic dipole anomaly shows that the distribution of distant galaxies and quasars doesn’t align with patterns seen in the leftover glow of the Big Bang. If confirmed, this discrepancy could undermine the foundation of the standard model of cosmology and force researchers to rethink how the universe is structured from the ground up.

A new philosophical look at space-time challenges the popular view that the past, present, and future all exist together in a timeless "block universe." The argument suggests that physicists may be blurring the difference between things that exist and things that merely occur, creating deep confusion about what space-time actually is.

Using Australia’s ASKAP radio telescope, researchers traced the bursts to a rare stellar duo in which a dense white dwarf is relentlessly siphoning material from a nearby red dwarf companion. As the stolen matter spirals inward, the system unleashes powerful radio waves and X-rays every 1.4 hours.

At its heart lies a supermassive black hole about 100 million times the mass of the Sun, while its graceful spiral arms sparkle with young star clusters and dark clouds of dust. But as M88 plunges deeper into the cluster over the next few hundred million years, powerful forces will strip away much of the gas it needs to create new stars.

Scientists discovered that Saturn’s changing “rotation rate” was never caused by the planet speeding up or slowing down, but by powerful winds high in its atmosphere. Webb’s unprecedented observations revealed that Saturn’s northern lights actively heat the atmosphere, creating winds that generate electrical currents, which then power the aurora all over again in a self-sustaining cycle.

Scientists believe the blast was powered by a rapidly spinning magnetar, an exotic neutron star with unbelievably strong magnetic fields. The event, called SN 2017egm, erupted 440 million light-years away and may help explain why some supernovae become extraordinarily bright.

Instead of lasting a few hours or days like normal solar radio bursts, this one persisted for an astonishing 19 days — shattering the previous record. Using a fleet of spacecraft spread across the solar system, researchers tracked the mysterious signal to a massive magnetic structure on the Sun called a helmet streamer.

Physicists created a new model predicting how dark matter could subtly distort gravitational waves produced during black hole mergers. When they tested the method on real LIGO data, one signal stood out as potentially carrying a dark matter imprint.

Stretching roughly 1,300 kilometers, Shalbatana Vallis was carved billions of years ago when enormous floods of groundwater burst onto the surface, gouging deep winding channels across the landscape. Today, the region is a striking mix of ancient flood scars, collapsed “chaotic terrain,” lava-smoothed plains, volcanic ash, and battered impact craters — all hinting at a Mars that may once have been far warmer and wetter than it is now.

Rapid urban growth is lighting up countries like China and India, while parts of Europe are dimming due to energy-saving efforts and new lighting technologies. The most detailed satellite analysis yet shows these shifts happening faster and more unevenly than expected. Even global trends can mask sharp local contrasts, from war-related blackouts to deliberate reductions in light pollution.

Instead, it’s noticeably skewed, and researchers now think they understand why. By analyzing years of data from the Cassini spacecraft, scientists found that a key region where solar particles enter Saturn’s atmosphere is consistently shifted to one side. This distortion appears to be driven by the planet’s rapid spin combined with a thick cloud of charged particles coming from its moon Enceladus.

Riding aboard the powerful SLS rocket, the Orion spacecraft is now on a 10-day journey that will test critical systems, push human spaceflight farther than it’s gone in decades, and set the stage for future Moon landings and eventual missions to Mars.

GRB 250702B, detected by NASA’s James Webb Space Telescope and a global network of observatories, lasted an astonishing seven hours—far longer than typical gamma-ray bursts, which usually fade in under a minute.

Scientists found that while sperm can still swim normally, they lose their sense of direction without gravity, making it harder to reach and fertilize an egg. In lab experiments simulating space conditions, far fewer sperm successfully made it through a maze designed to mimic the reproductive tract, and fertilization rates in mice dropped by about 30%.

Mysterious dips in starlight turned out to be massive rings of plasma swirling in the stars’ magnetic fields. These structures act like built-in space weather monitors, revealing how energetic particles affect nearby planets. The findings could reshape how we think about whether planets around these common stars can survive—or even host life.

Scientists have discovered that even relatively small, localized storms can hurl water vapor high into the atmosphere, where it breaks apart and escapes.

Using new data from ESA’s Gaia mission and NASA archives, researchers pinpointed worlds in the “habitable zone,” where temperatures could allow liquid water to exist. Some of the most intriguing targets include nearby systems like TRAPPIST-1 and Proxima Centauri, offering tantalizing possibilities just dozens of light-years away.

The comet, C/2025 K1 (ATLAS), wasn’t even the original target, but when researchers pivoted to it, they unknowingly caught it mid-disintegration into multiple pieces.

The Small Magellanic Cloud’s stars move in chaotic patterns because it slammed into its larger neighbor millions of years ago. That collision disrupted its structure and even created the illusion that its gas was rotating. The discovery means this once “textbook” galaxy may not be as typical as astronomers believed.

Formed by a dying star, the “Exposed Cranium” nebula shows layered gas and a dark central divide that creates its eerie shape. Webb’s infrared view suggests powerful jets may be shaping the structure. The images capture a brief and dramatic phase in a star’s final evolution.

Over billions of years, the Sun’s solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a frozen desert. NASA’s twin-spacecraft ESCAPADE mission aims to watch this process in action by measuring how the solar wind interacts with Mars’ fragile magnetic environment. The findings could reveal how Mars lost its habitability—and help prepare humans for future missions there.

The journey may have carried the solar system away from the galaxy’s crowded center into a calmer region where life could eventually emerge.

But they’re far from nothing. Even in these vast empty regions, the fundamental quantum fields that fill all of space remain, carrying a small but real amount of energy known as vacuum energy, or dark energy. While this energy is overwhelmed by matter in galaxies and clusters, in the deep emptiness of cosmic voids it becomes dominant.

Images from NASA’s DART mission revealed faint streaks on the moon Dimorphos—evidence of slow “cosmic snowballs” drifting from its parent asteroid, Didymos. The discovery provides the first direct visual proof that sunlight can spin asteroids fast enough to shed debris that lands on nearby companions. It also shows that near-Earth asteroids are much more active and constantly reshaped than scientists once believed.

The galaxy, COSMOS-74706, dates back about 11.5 billion years and contains a stellar bar, a bright, linear band of stars and gas stretching across its center, similar to the one in our own Milky Way.
