An investigation issued 61 recommendations, and NASA says no additional crews will fly aboard […]

Microsoft’s Project Silica demonstrates that digital data can be stored in ordinary borosilicate glass for over 10,000 years. Using femtosecond lasers, researchers encode information as microscopic 3D voxels, achieving densities of 4.8 terabytes on a 2mm sheet. Unlike magnetic tapes or hard drives that degrade within decades, glass resists heat, moisture, and dust. …

A new global map of small mare ridges suggests the Moon’s tectonic activity is younger and more widespread than previously believed. Researchers identified more than 1,100 previously unknown ridges, showing the lunar crust is still shrinking. These features, formed by thrust faults similar to lobate scarps, indicate moonquakes could occur across much broader regions…

New research suggests Saturn’s largest moon Titan and its iconic rings may share a violent origin. Simulations indicate Titan formed after a massive collision between two moons about 100 to 200 million years ago, resurfacing Titan and altering its orbit. The resulting instability likely shattered smaller moons, sending icy debris inward to create Saturn’s surprisi…

ESA’s CHEOPS mission has uncovered a surprising rocky planet at the outer edge of the LHS 1903 system. Located 116 light-years away, the discovery defies expectations that outer planets are gas giants. Scientists say the finding offers rare evidence that planets can form in gas-depleted environments, challenging current planetary formation models.

Physicists have proposed a new concept called spacetime quasicrystals, orderly structures that never repeat but exist across space and time. If proven, they could help explain the universe’s deep structure, quantum gravity, and hidden dimensions, while preserving key laws of relativity even at extremely small scales.

Scientists have detected a possible ultra-fast pulsar spinning every 8.19 milliseconds near the Milky Way’s central black hole. If confirmed, this rare object could act as a precise cosmic clock, helping researchers study how gravity behaves in extreme environments and offering a powerful new way to test Einstein’s theory of general relativity near a supermassive […]

New research suggests the Universe’s expansion could eventually reverse, leading to a dramatic “Big Crunch.” By analyzing dark energy survey data, scientists propose expansion may stop in about 11 billion years before contraction begins. The model predicts a final cosmic collapse roughly 20 billion years from now, though uncertainties remain and future observati…

Astronomers have identified two merging supermassive black hole systems named Gondor and Rohan using a new method combining quasars and gravitational wave background signals. The discovery offers a fresh way to map black hole mergers and understand galaxy evolution and cosmic gravitational waves in a clearer and more systematic manner.

A new Hubble image reveals twin beams blasting from a hidden dying star inside the Egg Nebula, a rare pre-planetary phase. The symmetrical arcs and glowing lobes show how Sun-like stars shed dust and gas before forming planetary nebulae, offering scientists a rare glimpse into stellar evolution.

Astronomers are closely tracking the bright green comet C/2024 E1 as it approaches Earth and prepares for a future escape from the solar system. Originating from the distant Oort Cloud, the city-sized comet is on a hyperbolic path and is expected to be permanently ejected after its close solar encounter, similar to the interstellar object […]

NASA is analysing data from a recent Artemis II confidence test that examined the SLS liquid hydrogen tank and replaced seals. Despite a ground equipment flow issue, engineers gathered critical performance data and will inspect systems before scheduling the next wet dress rehearsal, with March still considered the earliest possible launch window.

Scientists have refined Jupiter’s size and shape using modern radio signal observations, finding the giant planet slightly smaller and more flattened than earlier estimates. Though the difference is only a few kilometres, researchers say it greatly improves models of Jupiter’s interior, gravity, and atmospheric structure, offering deeper insights into gas giant fo…

NASA’s NEOWISE infrared telescope has provided striking evidence that a massive star in the Andromeda galaxy collapsed directly into a black hole without exploding as a supernova. The star, M31-2014-DS1, faded dramatically in visible light while leaving a faint infrared glow from surrounding dust. Astronomers say this rare “failed supernova” offers one of the cl…

Astronomers have discovered a rare inside-out planetary system around LHS 1903, where a rocky planet exists beyond gas giants. Using ESA’s CHEOPS telescope, researchers found evidence that planets formed one after another in a gas-depleted environment, challenging long-standing theories about how planetary systems form and evolve across the galaxy.

NASA has successfully flown its 40-inch CATNLF laminar-flow wing model aboard an F-15B aircraft in January 2026. The test confirmed the drag-reducing design performs safely in flight.
