NASA Science

NASA Science seeks to discover the secrets of the universe, search for life elsewhere, and protect and improve life on Earth and in space.

A pair of colliding spiral galaxies. Here, both spirals are shown face on, with the smaller of the two galaxies, IC 2163, at the upper left of the larger galaxy, NGC 2207, which dominates the center and lower right of the image. Both galaxies have long, spiraling, silver blue arms, dotted with specs of blue and red. Toward our upper left, the curving arms overlap, and bend toward their neighbors' core.

Featured Missions

Our mission milestones showcase the breadth and depth of NASA science.

IMAP

Launched September 24, 2025, IMAP will help researchers better understand the boundary of the heliosphere, a huge bubble created by the Sun surrounding and protecting our solar system.

Behind Earth, the bright Sun is peaking out, filling the dark expanse of space with streaks of white light. The two spacecraft orbit above Earth, large hexagonal cylinders with long poles sticking out horizontally in 4 directions.

TRACERS

Launched July 23, 2025, TRACERS will study magnetic reconnection—when solar activity disrupts Earth’s magnetic field—to help scientists better understand and prepare for the effects of space weather.

Helio Highlight: Comets, the Sun, and You

Interstellar comet 3I/ATLAS passed through the inner solar system in the last months of 2025. By studying comets like 3I/ATLAS, scientists can learn more about the Sun and other stars, and about how planetary systems form in the first place.

Citizen Science


Join NASA researchers and discover the secrets of the universe, search for life elsewhere, and protect and improve life on Earth and in space.

Through these projects, sometimes called “citizen science” or “participatory science” projects, volunteers and amateurs have helped make thousands of important scientific discoveries. These projects are open to everyone (no citizenship required).
