“One of the paper’s reviewers called it a Rosetta Stone for Mars,” said Dr. Yang Liu of NASA’s Jet Propulsion Laboratory. NASA stated the find provides “a rare snapshot” of the planet’s crust and formation. Teghaza 001 samples the earliest Martian crust The meteorite consists of eight fragments totaling 798.5 grams. The largest piece weighs … Read more
Astronomers have identified the first known green star, a dense white dwarf designated WD J1330+6435 that appears to glow in a shade of chartreuse due to the ingestion of rocky planetary debris. Located approximately 280 light-years from Earth in the constellation Draco, the star’s unique color is the result of its atmosphere being enriched with … Read more
The European Space Agency released the initial data and first images from the Copernicus Sentinel-3C satellite roughly two weeks after its launch, providing early confirmation of instrument performance across oceans, land, and ice sheets. According to eu-space.europa.eu, the newly arrived satellite will operate in a novel three-satellite configuration alongside Sentinel-3A and Sentinel-3B to expand environmental … Read more
Solar System Weather Extreme Conditions Across Rocky and Gas Worlds World Space Week focuses attention on the meteorology of our broader Solar System, featuring alien worlds plagued by colossal storms, severe temperature swings, supersonic gales, and clouds formed from materials completely unlike water. At its simplest, weather is driven by the transfer of energy. Across … Read more
Eastern Pacific Ocean water temperatures tied a new record at 3.07 degrees Celsius above average last weekend, triggering a Super El Niño event that researchers warn is the strongest in at least 1,000 years. Climate data from ancient Galapagos coral samples indicates current fluctuations are 16.2 percent greater than those of the past 150 years, … Read more
The robotic spacecraft launched to rescue NASA’s aging Neil Gehrels Swift Observatory disintegrated over Earth’s atmosphere on Friday, September 27, 2026, less than three months after its initial deployment. Katalyst Space Technologies confirmed the destruction of its three-armed spacecraft, named Link, bringing the $30-million salvage mission to a premature close. The observatory itself is now … Read more
According to a study published in the journal Nature, multidecadal changes in Earth’s rotation are driven by deep interior mechanisms where gravitational, electromagnetic, and topographic forces compete to speed up or slow down the planet every couple of decades. The research offers new insights into how our planet’s core and mantle interact to subtly alter … Read more
According to a study published in the journal Space Weather, an international research team has solved a 178-year-old mystery regarding an 1841 train delay in Exeter, England, determining through archival records that the geomagnetic disturbance actually occurred on October 18, 1848. The finding corrects a longstanding historical timeline of how solar activity impacts human infrastructure. … Read more
Christa Pike faces execution by lethal injection on September 30 at the Riverbend Maximum Security Institution in Nashville, Tennessee. United Nations human rights experts and Amnesty International have called for an immediate halt to the execution, citing her history of childhood abuse and nearly three decades on death row. Death Row Timeline and Legal Status … Read more
Earth’s unusually large Moon may have formed in just five hours following a cataclysmic collision with a Mars-sized protoplanet named Theia, according to new high-resolution computer simulations published in The Astrophysical Journal Letters. The findings reshape the long-standing giant impact hypothesis by demonstrating that the physical strength and temperature of early planetary bodies played a … Read more
