The phenomenon of a Full Moon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures the entire side of the Moon that faces us gleams under sunlight. Thanks to the Moon’s orbit around Earth, the angle of sunlight hitting the lunar surface and being reflected back toContinue reading "2026 Full Moon calendar: When to see the Full Moon and phases"

Astronomers have found strong evidence that some mysterious, minutes-long X-ray flashes are produced when two neutron stars collide and create a magnetar. One record-setting event glowed in X-rays for nearly 10 minutes, potentially opening a new way to find these extreme cosmic mergers.

NASA’s Perseverance rover has uncovered a surprisingly complicated history of water in Jezero Crater. Scientists expected the crater’s Margin Unit to contain lake sediments, but instead found ancient igneous rocks that were altered by water on at least three separate occasions.

Powerful jets from supermassive black holes can disturb star-forming gas far beyond a galaxy’s visible edge, leaving a glowing trail hundreds of thousands of light-years long. By keeping this gas hot and preventing it from falling inward, the jets may help determine whether a galaxy keeps forming stars or becomes quiet.

NASA’s SpaceX Crew-13 mission is scheduled to launch four astronauts to the International Space Station on October 1. The Dragon could reach the orbiting laboratory in just 7 hours and 50 minutes, making it the fastest U.S. spacecraft journey to the ISS in history.

NASA’s Curiosity rover marked 5,000 Martian days by capturing morning and afternoon views that were blended into a striking Mars “postcard.” The panorama shows Curiosity, its tracks, and the enormous landscape surrounding Mount Sharp and Gale Crater.

Enceladus may naturally separate and concentrate chemicals from its hidden ocean as droplets slowly freeze and shatter on their way into space. The process could explain Cassini’s puzzling ice-grain chemistry while giving future spacecraft a powerful advantage in searching for organic compounds and clues to life.

NASA and SpaceX could launch four astronauts to the International Space Station on October 1, with the Dragon spacecraft reaching orbiting outpost less than nine hours after liftoff. Crew-13 will join Expedition 75 after teams complete a final round of intensive launch-readiness checks.

CosmoCube will use the far side of the Moon as a shield from Earth’s radio noise to search for a faint signal from the universe before the first stars existed. The suitcase-sized satellite could reveal how the cosmic dark ages ended and how dark matter helped build the first galaxies.

Spaceflight may dramatically change the gut within weeks, causing bacteria to break down more protein as food moves more slowly through the intestines. The shift could help explain astronaut constipation and may have wider effects on health, making it an important concern for future missions to Mars.

JWST has revealed that young planetary systems lose their planet-building gas through a changing mix of powerful jets, molecular winds, and radiation-driven outflows. As the disks age and their gas disappears, giant planets face a shrinking window to build massive atmospheres.

Measurements of ancient light from the cosmic microwave background suggest that the universe is remarkably flat. But that does not prove it is infinite, because the observable cosmos could be only a small patch of a much larger curved universe. Space could even be flat while wrapping around on itself in exotic ways.

Artemis II astronauts Victor Glover and Reid Wiseman are transitioning to emeritus status at NASA after their historic journey around the Moon earlier this year. The pair will continue advising and mentoring NASA teams as preparations accelerate for Artemis III and future lunar missions. Their experience with Orion and deep-space operations could prove especially valuable as NASA works toward returning astronauts to the lunar surface.

Scientists think beneficial fungi could help transform nutrient-poor lunar and Martian regolith into a material capable of supporting crops. By helping plants access nutrients and withstand harsh conditions, these microbes could someday make self-sustaining space farming more realistic.

A dead white dwarf with no detectable disk has somehow produced a powerful shock wave that appears to have persisted for at least 1,000 years. Its magnetic field may be partly responsible, but astronomers say an unexplained “mystery engine” may also be at work.

Ancient grains inside one of the oldest known meteorites reveal that a surprisingly strong magnetic field existed during the solar system’s first 200,000 years. The discovery suggests magnetism worked alongside gravity to help transform a vast cloud of gas and dust into the sun and planetary disk.
