A new modeling study argues that magnetic accretion and a magnetospheric cavity in Jupiter’s young circumplanetary disk can help explain why Jupiter formed four large moons while Saturn ended up dominated by Titan.

A University of Chicago student team using Sloan Digital Sky Survey data has identified an extremely metal-poor red giant in the Milky Way that researchers say likely originated outside our galaxy.

NASA’s Artemis II mission ended with a successful splashdown, marking the first return of astronauts from the moon since the Apollo era and Orion’s first crewed deep-space landing.

NASA’s Orion spacecraft splashed down off the California coast on April 10, bringing the four-person Artemis 2 crew home after a 10-day test flight around the moon.

A Falcon 9 lifted Northrop Grumman’s NG-24 Cygnus XL freighter toward the International Space Station on April 11, carrying more than five tons of supplies and research cargo for the orbiting laboratory.

With Artemis II back on Earth, NASA is shifting from proving it can send astronauts around the Moon again to the harder task of landing crews and building a longer-term lunar presence

NASA’s Artemis 2 crew has returned to Earth after a 10-day mission around the moon, closing the first crewed Artemis flight and setting a new human-distance record in the process.

NASA’s Artemis 2 mission is set to end with an Orion splashdown in the Pacific Ocean off the coast of San Diego, bringing home the first crewed moon mission since Apollo 17.

A newly released NASA timelapse from Artemis 2 captures the moon fully covering the sun during the crew’s far-side lunar flyby, creating one of the rarest eclipse views in human spaceflight.

The Northeast Astronomy Forum & Space Expo returns April 11-12 in Suffern, New York, bringing astronauts, NASA experts, exhibitors, workshops, and thousands of attendees together for its 35th year.

Despite problems seen on Artemis I, NASA says testing, analysis, and trajectory changes support confidence in the Artemis II heat shield for crewed lunar-return reentry.

NASA has outlined indoor test capabilities at its Unmanned Autonomy Research Complex, including a programmable WindShaper array and a WindProbe system for mapping airflow during low-speed flight research.

NASA has published an extraordinary Earthset image captured by the Artemis II crew during its far-side lunar flyby, offering both a scientific record and a powerful symbol of the mission’s return to deep space.

NASA has highlighted indoor testing assets at its Unmanned Autonomy Research Complex, including a programmable WindShaper fan wall and a mobile WindProbe system tied to motion capture.

NASA highlighted indoor testing facilities at its Unmanned Autonomy Research Complex, including a programmable WindShaper array designed to simulate steady winds, gusts, and gradients for low-speed and hovering flight.

NASA says the Deep Space Network has taken over Artemis II communications after launch, marking the first time in more than half a century that the network has communicated with a crewed spacecraft traveling through deep

NASA satellite imagery shows an early April storm briefly coating southern Argentina’s high plains in snow, offering a sharp view of how weather and terrain interact along the dry eastern edge of the Andes.

Six days into NASA’s Artemis II mission, the Orion crew passed the Apollo 13 distance record, marking the farthest humans have traveled from Earth and underscoring the agency’s plan to return crews to the Moon.

Satellite and ground-based measurements indicate that Florida’s escalating drought has dried shallow groundwater in northern and central parts of the state, extending the crisis beyond surface conditions.

NASA has published the first official moon-flyby images from Artemis II, including a rare in-space solar eclipse and views of terrain on the lunar far side as the crew returns to Earth.
