Saturn's moon Phoebe, discovered in 1899, orbits backward, a clear sign it formed elsewhere. Data from the Cassini mission reveals it's a captured planetary embryo from the outer solar system, responsible for Saturn's largest ring and the unique appearance of Iapetus.
New research suggests Europa's ocean may be less habitable than thought due to mineral transport challenges, while the detection of ammonia offers a counterpoint. Meanwhile, SpaceX plans a million satellites, Artemis 2 faces delays, and AI assists Mars rovers.
Scientists have unveiled high-resolution details of the bacterial flagellar motor, a complex molecular machine that drives bacterial movement. This discovery deepens our understanding of biological mechanics and reignites debates about the origin of life.
The James Webb Space Telescope has captured the first direct image of planet formation in action around the young star HOPS-315. This breakthrough observation reveals the crucial moment when gas condenses into solid material, offering unprecedented insights into the earliest stages of planetary system development and providing a potential mirror to our own solar system's birth.
Could CERN's Large Hadron Collider create a doomsday black hole? While theoretically possible under certain speculative physics, the scientific consensus and evidence suggest the risks are vanishingly small, with microscopic black holes likely evaporating instantly or having negligible gravitational impact.
Astronomers may have found the first evidence of the elusive Planet Nine, a massive hypothetical world in the outer solar system. New analysis of decades-old infrared data reveals a single candidate object, but further observation is needed for confirmation.
Explore the galaxy's most bizarre exoplanets, from worlds with incredibly short years to planets orbiting multiple suns and the mysterious rogue planets drifting through interstellar space. Discover the science behind these cosmic oddities and what they reveal about the universe.
The James Webb Space Telescope has discovered early galaxies that are far too mature and bright for current cosmological models, suggesting the early universe was more developed than previously thought. This finding may point to the existence of 'Dark Stars.'
Astronomers have finally detected the universe's missing baryonic matter, hidden within vast, hot gas filaments of the cosmic web stretching millions of light-years across intergalactic space. This discovery validates key cosmological models and opens new avenues for understanding cosmic evolution.
UY Scuti, a red supergiant in the constellation Scutum, is currently the largest known star by radius, capable of containing approximately 5 billion Suns. This colossal star represents the extreme end of stellar evolution, far surpassing the scale of our own Sun.
