The Republic of Latvia signed the Artemis Accords Monday during a ceremony hosted by NASA at the agency’s headquarters in Washington, becoming the 62nd nation to commit to responsible space exploration for all humanity. “We are proud to welcome Latvia to the Artemis Accords,” said NASA Administrator Jared Isaacman. “Each new signatory strengthens a coalition committed to the transparent and peaceful exploration of space. The accords are the

This shimmering region of star-formation, a close-up of the Trifid Nebula about 5,000 light-years from Earth, was captured in intricate detail by NASA’s Hubble Space Telescope. The colors in Hubble’s visible light image, which marks the 36th anniversary of the mission’s launch on April 24, are reminiscent of an underwater scene filled with fine-grained sediments fluttering through the ocean’s depths.

The coastal province features striking tropical karst landscapes and sandy beaches alongside a mix of natural land cover and developed areas.

Studying planets in other solar systems isn’t easy, especially when their host stars keep stealing the spotlight. NASA’s Pandora mission will cut through the noise, revealing what the atmospheres of these distant worlds are really made of.

The report adds to the growing documentation on commercial data’s contributions to Earth science research and applications.

To conserve power, engineers at NASA’s Jet Propulsion Laboratory needed to turn off one of the science instruments on the most distant spacecraft ever built.

NASA’s Human Research Program (HRP) uses research to develop methods to protect the health and performance of astronauts in space. In support of NASA’s goals for long-term missions on the surface of the Moon and human exploration of Mars, HRP is using ground research facilities, the International Space Station, and analog environments to monitor human health in deep space. NASA’s Artemis II mission was the first

NASA and the U.S. Office of Personnel Management (OPM) launched the NASA Force website on Friday, opening applications for roles aimed at recruiting the nation’s top engineers and technologists to support America’s air and space program. NASA Force, a new hiring initiative developed in partnership with OPM, will recruit and place high-impact technical talent into mission-critical roles supporting NASA’s exploration, research, and advanced technology priorities,

Scientists are working to understand exactly how these waves behave, and the team behind NASA’s Heliophysics Audified: Resonances in Plasmas (HARP) citizen science project approaches this in a unique way: they compare the Earth’s magnetic field to a giant harp in space.

An observation made by NASA’s SPHEREx mission reveals vast frozen complexes in the Cygnus X star-forming region of the Milky Way galaxy. The chemical signature of water ice is shown as bright blue structures, while polycyclic aromatic hydrocarbons are in orange.

An observation made by NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) shows the chemical signatures of water ice (shown in bright blue) and polycyclic aromatic hydrocarbons (orange) in Cygnus X, one of the most active and turbulent regions of star birth in our Milky Way galaxy. The
