Includes title, explanation, image URL, copyright, and media type (image or video). Running since June 16, 1995 — one of the most popular websites across all federal agencies. Get the Astronomy Picture of the Day — NASA's most popular API

Great for exploring a week or month of astronomical imagery. Maximum range is about 30 days per request. Get APOD images for a date range

Filter by distance threshold, date range, and minimum size. Critical for planetary defense monitoring. Get future close approaches of asteroids to Earth from JPL CNEOS

CMEs are massive bursts of solar wind and magnetic fields from the Sun. Earth-directed CMEs cause geomagnetic storms and aurora. Default: last 30 days. Get Coronal Mass Ejection (CME) events from NASA DONKI

A unified feed of all space weather events: CMEs, flares, storms, shocks, and radiation events. Good for a quick overview of recent solar activity. Get all recent DONKI space weather notifications

Each entry includes coordinates, sun position, and image identifier for constructing the full image URL. Get EPIC Earth images for a specific date

Useful for finding specific dates of interest before requesting images. List all dates with available EPIC Earth images

5 million km from Earth. Available in natural color or enhanced color. Get the latest full-disk images of Earth from the DSCOVR satellite

List all EONET natural event categories

Includes location, velocity, energy (kilotons of TNT equivalent), and altitude. Covers events worldwide. Get atmospheric fireball (bolide) events detected by US government sensors

Includes Kp index and linked CME/shock data. Storms above Kp=7 are severe, Kp=9 is extreme. Affects power grids, GPS, satellites, and enables aurora at low latitudes. Get geomagnetic storm events from NASA DONKI

These are the most promising candidates for life. Get exoplanets in the habitable zone — where liquid water could exist

Shocks often precede geomagnetic storms and are caused by CME-driven disturbances in the solar wind. Get interplanetary shock wave events from NASA DONKI

Curiosity is still active and sending new photos. Opportunity and Spirit missions have ended but their full archives are available. Get the most recent photos from a Mars rover

Essential for understanding what data is available. Get the mission manifest for a Mars rover

Filter by camera: FHAZ (front hazard), RHAZ (rear hazard), MAST (mast), CHEMCAM, MAHLI, MARDI, NAVCAM. Curiosity has 800K+ photos. Get Mars rover photos by sol number and camera

Easier than using sol numbers. Works with all three rovers. Get Mars rover photos by Earth date

Use NASA IDs from search results. Get download URLs for a NASA media asset by its NASA ID

Get full metadata for a NASA media asset

Categories include wildfires, volcanic eruptions, severe storms, sea ice, dust/haze, floods, and earthquakes. Includes coordinates and source links. Get active natural events worldwide: wildfires, volcanoes, storms, icebergs

Returns 20 asteroids per page. Use for exploring the complete known catalog of near-Earth objects. Browse the complete catalog of known near-Earth asteroids

Includes estimated diameter, velocity, miss distance, and whether potentially hazardous. Source: NASA NeoWs. Get near-Earth asteroids approaching within a date range

Use SPK-IDs from the feed endpoint. Get detailed information about a specific asteroid by its NASA SPK-ID

Shows how exoplanet science has exploded since Kepler's launch in 2009. Get global exoplanet discovery statistics: totals, methods, yearly trends

The Van Allen radiation belts can be energized during geomagnetic storms, posing risks to satellites in medium Earth orbit. Get radiation belt enhancement events from NASA DONKI

Perfect for discovering amazing space imagery you might have missed. Default: 5 random images. Get random Astronomy Pictures of the Day from the 30-year archive

SEPs are dangerous to astronauts and can damage satellite electronics. Get Solar Energetic Particle (SEP) events from NASA DONKI

Classes: C (common), M (moderate), X (extreme). X-class flares cause radio blackouts and satellite disruption. Includes begin/peak/end times, active region, and instruments that detected it. Get solar flare events by class (C, M, X) from NASA DONKI

Transit is the most productive method (>75% of all discoveries). Kepler and TESS are the primary transit missions. Get exoplanets discovered via the transit method (Kepler/TESS)

Filter by planet name, discovery method (Transit, Radial Velocity, Imaging, Microlensing), discovery facility (Kepler, TESS, Keck), or year. Returns orbital period, radius, mass, equilibrium temperature. Search confirmed exoplanets by name, discovery method, facility, or year

Covers every mission: Apollo, Space Shuttle, ISS, Hubble, Webb, Mars rovers, and more. Filter by media type and year range. Search NASA's image and video library — 140,000+ assets

NASA technologies have been adapted into thousands of commercial products — from memory foam to water purification systems. Search NASA patents and technology spinoffs available for licensing
