Researchers propose that hydrogen gas from the early Universe emitted detectable radio waves influenced by dark matter. Studying these signals, especially from the Moon’s radio-quiet environment, could reveal how dark matter clumped together before the first stars formed. This approach opens a new window into the mysterious cosmic era just 100 million years after the Big Bang.

Researchers suggest that dark matter might subtly color light red or blue as it passes through, revealing traces of its existence. Using a network-like model of particle connections, they argue that light could be influenced indirectly by Dark Matter through intermediaries. Detecting these tints could unlock a whole new way to explore the hidden 85% of the Universe. The finding could reshape how telescopes search for cosmic mysteries.

Our Milky Way is far from calm — it ripples with a colossal wave spanning tens of thousands of light-years, revealed by ESA’s Gaia telescope. This wave, moving through the galaxy’s disc like ripples in water, shifts stars up and down in a mesmerizing pattern. Astronomers, studying young giant and Cepheid stars, think even the galactic gas joins the motion. The origin remains mysterious, possibly from an ancient collision, but upcoming Gaia data could soon unveil the secrets of our galaxy’s undulating heart.

Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the driving force behind creation. Their simulations show that gravity and quantum mechanics may alone explain the structure of the cosmos. This elegant approach challenges traditional Big Bang interpretations and revives a century-old idea rooted in Einstein’s work.

Researchers from The University of Western Australia node at the International Centre for Radio Astronomy Research (ICRAR) have uncovered a colossal bridge of neutral hydrogen gas linking two dwarf galaxies, which spans an astonishing 185,000 light-years between galaxies NGC 4532 and DDO 137, located 53 million light-years from Earth.

Mars’ north polar vortex locks its atmosphere in extreme cold and darkness, freezing out water vapor and triggering a dramatic rise in ozone. Scientists found that the lack of sunlight and moisture lets ozone build up unchecked. This discovery, made with data from ESA’s and NASA’s orbiters, could reveal clues about Mars’ past atmospheric chemistry and potential for life.

Scientists at Johns Hopkins may be closing in on dark matter’s elusive trail, uncovering a mysterious gamma ray glow at the heart of our galaxy that could signal unseen matter colliding — or perhaps the frantic spin of dying stars. Using advanced simulations that account for the Milky Way’s ancient formation, researchers found a near-perfect match between theoretical and observed gamma ray maps, tightening the link between dark matter and this puzzling energy. Yet the mystery remains: could these signals come from millisecond pulsars instead?

Researchers have discovered chemical fingerprints of Earth's earliest incarnation, preserved in ancient mantle rocks. A unique imbalance in potassium isotopes points to remnants of “proto Earth” material that survived the planet’s violent formation. The study suggests the original building blocks of Earth remain hidden beneath its surface, offering a direct glimpse into our planet’s ancient origins.

Scientists from NASA and Chalmers University have discovered that incompatible substances can mix on Titan’s icy surface, breaking the “like dissolves like” rule of chemistry. Under ultra-cold conditions, hydrogen cyanide can form stable crystals with methane and ethane. This surprising reaction could help explain Titan’s mysterious landscapes and offer clues to how life’s building blocks formed.

For the first time, scientists observed a black hole tearing apart a star far from its galaxy’s center, producing the fastest-changing radio signals ever recorded. The event, AT 2024tvd, revealed delayed bursts of energy months after the initial destruction, hinting at mysterious, episodic black hole activity. This rare find reshapes understanding of where supermassive black holes reside and how they evolve.

Researchers discovered a new field of ancient tektites in South Australia, revealing a long-forgotten asteroid impact. These 11-million-year-old glass fragments differ chemically and geographically from other known tektites. Although the crater remains missing, the find exposes a massive event once thought unrecorded, offering clues to Earth’s tumultuous past and planetary defense.

Ryugu’s samples reveal that water activity on asteroids lasted far longer than scientists thought, possibly reshaping theories of how Earth gained its oceans. A billion-year-old impact may have melted ancient ice, keeping asteroids wet and influential far into solar system history.

CO₂ ice blocks on Mars may dig gullies as they slide and sublimate in the thin atmosphere. In lab experiments, scientists recreated these eerie, worm-like movements under Martian conditions. The findings help explain unusual dune formations and deepen our understanding of how alien landscapes evolve.

Scientists at the University of Hawaiʻi have discovered why it rains on the Sun. Solar rain, made of cooling plasma, forms rapidly during solar flares, a mystery now solved by modeling time-varying elements like iron. The finding upends long-held assumptions about the Sun’s atmosphere and could improve predictions of space weather events. It’s a breakthrough that forces a rewrite of how we understand the Sun’s outer layers.

Scientists at TU Wien have uncovered that quantum correlations can stabilize time crystals—structures that oscillate in time without an external driver. Contrary to previous assumptions, quantum fluctuations enhance rather than hinder their formation. Using a laser-trapped lattice, the team demonstrated self-organizing rhythmic behavior arising purely from particle interactions. The finding could revolutionize quantum technology design.

Astronomers are investigating a strange class of exoplanets known as eccentric warm Jupiters — massive gas giants that orbit their stars in unexpected, elongated paths. Unlike their close-orbiting “hot Jupiter” cousins, these planets seem to follow mysterious rules, aligning neatly with their stars despite their bizarre trajectories. Theories suggest that companion planets, surrounding nebulas, or even stellar waves could be shaping these odd orbits in ways never seen before.

Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki University suggests these signals might carry “beats” — patterns formed by overlapping waves from supermassive black holes. This subtle modulation could help scientists tell whether the waves stem from ancient cosmic inflation or nearby black hole binaries, potentially identifying the true source of spacetime’s gentle vibrations.

High above the Sun’s blazing equator lie its mysterious poles, the birthplace of fast solar winds and the heart of its magnetic heartbeat. For decades, scientists have struggled to see these regions, hidden from Earth’s orbit. With the upcoming Solar Polar-orbit Observatory (SPO) mission, humanity will finally gain a direct view of the poles, unlocking secrets about the Sun’s magnetic cycles, space weather, and the forces that shape the heliosphere.

Scientists imaged the heart of the OJ 287 galaxy, uncovering a curved plasma jet around what appears to be two merging supermassive black holes.
