Closest Ever Images to Sun

Featured Missions

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

All Science Missions
An illustration showing the 2 TRACERS spacecraft. Filling the bottom half of the landscape image is a cloudy Earth. 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

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.

NEO Surveyor

NEO Surveyor is expected to launch no earlier than September 2027. It is the first space telescope specifically designed to hunt asteroids and comets that may be potential hazards to Earth.

Dive into the Universe about Astrophysics
A concentration of bright blue stars occupies the bottom right corner of the image. At bottom center within them is a small blue bubble. The stars and bubble are part of a diffuse dwarf galaxy that extends beyond the image border. Background galaxies are scattered across the image, with some particularly prominent spirals located at upper left and upper right. The background of space is black.

The Future of Exploration

The Nancy Grace Roman Space Telescope will investigate dark matter, dark energy, exoplanets and other mysteries of the universe.

An M dwarf star is seen with three exoplanets.

Are We Alone?

By studying exoplanets we can compare our planet to thousands more, and find out if there are other habitable worlds in the galaxy.

Nicky Notes

To the NASA Science Community – As the nation’s leader in Earth and space science, NASA Science operates within the broader context of the federal government and its priorities. As part of the Executive Branch, we are always responsive to the direction set by the Administration, including executive orders and policy guidance that relate to our programs and activities.

Explore our changing planet

Earth is our home, shared with millions of species. Rapid changes like rising temperatures and more frequent extreme weather are transforming our planet. For over 50 years, observations from space and ground have monitored these changes, guiding critical decisions in areas like agriculture and air quality. By understanding how our actions affect Earth's systems, we can help mitigate these impacts. Discover more about how you can make a difference in safeguarding our planet.
