Although this spiral galaxy appears unremarkable from afar, NGC 7456 is bursting with newborn stars and glowing gas, providing researchers with insight into galactic evolution.
Read moreAstronomers detected a black hole displaced nearly a kiloparsec from the center of a dwarf galaxy 230 million light-years away. Unlike most, it is actively feeding and producing radio jets, making it one of the most convincing off-nuclear cases ever confirmed. The discovery reveals that black holes can grow and shape galaxies even when not in the core, reshaping theories of cosmic evolution.
Read moreNASA has chosen 10 new astronaut candidates who will train for missions to the Moon and Mars. Their selection represents a powerful blend of talent and ambition, fueling humanity’s next great leaps into space.
Read moreCuriosity is exploring Mars’ boxwork terrain, where ridges and hollows may have formed from cementation and erosion. The rover has been documenting rock textures and chemistry, comparing smoother ridge rocks with nodular hollow-edge rocks. Scientists are weighing drill sites while also monitoring dust, clouds, and long-distance features across Gale Crater.
Read morePrimordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe. Researchers ran over 250,000 simulations to show how these fields shaped the cosmic web, then validated the results with observations. Their study sets a stricter upper limit on the fields’ strength, aligning with other data and suggesting important consequences for early star and galaxy formation.
Read moreIn Jezero Crater’s Bright Angel formation, Perseverance has found rocks rich in organic molecules and minerals linked to microbial metabolism. Their arrangement hints at redox reactions that resemble Earth’s life-driven chemistry. While not proof of Martian life, the findings qualify as “potential biosignatures” and make the stored sample a top candidate for return to Earth.
Read moreHubble’s latest look at Messier 96 reveals a warped spiral galaxy glowing with rings of stellar birth. The new details shed light on how stars emerge and influence their surroundings.
Read moreNASA has confirmed 6,000 exoplanets, marking a major milestone in humanity’s quest to understand other worlds. From gas giants hugging their stars to planets covered in lava or clouds of gemstones, the diversity of discoveries is staggering. With upcoming missions like the Roman Space Telescope and the Habitable Worlds Observatory, scientists are getting closer to detecting Earth-like planets, and possibly signs of life.
Read moreA new study challenges the dream of water-rich “Hycean” planets like K2-18b, suggesting that most sub-Neptunes lose their water deep into their interiors during formation. Instead of vast oceans, these worlds likely retain only a few percent of water at the surface.
Read moreJezero Crater’s rocks reveal three stages of water activity, shifting from hostile acidic fluids to more life-friendly alkaline ones. Perseverance’s discoveries guide future sampling and strengthen the hunt for past life on Mars.
