A super blue Moon rises above Kennedy Space Center in Florida on Monday, Aug. 18, 2024. Although not actually appearing blue, as the third full Moon in a season with four full Moons, this is called a “blue” Moon. The Moon at or near its closest point to Earth is a “super” Moon and can appear up to 14% bigger and brighter than normal full Moons. About 25% of all full Moons are super, but only 3% of full Moons are blue, with the next super blue Moons occurring as a pair in January and March 2037.

The Moon is seen as it sets behind the National Capitol Columns at The US National Arboretum on Wednesday, Jan. 31, 2018 in Washington. Today’s full Moon is unique for three reasons: it is the third in a series of supermoons, occurring when the Moon is closer to Earth in its orbit. It is also the second full moon of the month, commonly known as a blue moon. The moon will also be passing through Earth’s shadow, giving skywatchers in the right locations a view of a total lunar eclipse. Photo Credit: (NASA/Aubrey Gemignani)

A Super Blue Moon rises above the Mississippi River and the Crescent City Connection Bridge in New Orleans, Aug. 30. The full moon is “super” because it’s slightly closer to Earth and “blue” because it’s the second full moon in a month. About 25% of all full moons are supermoons, but only 3% of full moons are blue moons. The next super blue moons will occur in a pair in January and March 2037. New Orleans is home to NASA’s Michoud Assembly Facility, where stages for NASA’s SLS (Space Launch System) rocket and structures for Orion spacecraft are produced for the Artemis missions.

California's NASA Armstrong Flight Research Center photographer Carla Thomas takes photos on January 31 of the rare opportunity to capture a supermoon, a blue moon and a lunar eclipse at the same time. A supermoon occurs when the Moon is closer to Earth in its orbit and appearing 14 percent brighter than usual. As the second full moon of the month, this moon is also commonly known as a blue moon, though it will not be blue in appearance. The super blue moon passed through Earth's shadow and took on a reddish tint, known as a blood moon. This total lunar eclipse occurs when the Sun, Earth, and a full moon form a near-perfect lineup in space. The Moon passes directly behind the Earth into its umbra (shadow).

A supermoon rises over Huntsville, Alabama, home to NASA’s Marshall Space Flight Center, Aug. 19. Visible through Wednesday, Aug. 21, the full Moon is both a supermoon and a Blue Moon. Supermoons are the biggest and brightest full Moons of the year because the Moon is within 90% of its closest point to Earth. While not blue in color, the third full Moon in a season with four full Moons is called a “Blue Moon.” Huntsville is known as the “Rocket City” because of its proximity to NASA Marshall, which manages vital propulsion systems and hardware, launch vehicles, engineering technologies, and cutting-edge science for the agency.

iss073e0819960 (Oct. 3, 2025) --- The waxing gibbous Moon rises above Earth’s blue atmosphere in this photograph taken from the International Space Station as it orbited 263 miles above a cloudy Atlantic Ocean off the coast of Quebec, Canada.

This moon map shows the gravity gradients calculated by NASA GRAIL mission. Red and blue correspond to stronger gravity gradients.

This view from NASA Cassini spacecraft look toward the south polar region of Saturn largest moon, Titan, and show a depression within the moon orange and blue haze layers near the south pole.
Cassini casts powerful eyes on our home planet, and captures Earth, a pale blue orb -- and a faint suggestion of our moon -- among the glories of the Saturn system.

NASA's Cassini spacecraft looks towards the dark side of Saturn's largest moon, Titan, capturing the blue halo caused by a haze layer that hovers high in the moon's atmosphere. The haze that permeates Titan's atmosphere scatters sunlight and produces the orange color seen here. More on Titan's orange and blue hazes can be found at PIA14913. This view looks towards the side of Titan (3,200 miles or 5,150 kilometers across) that leads in its orbit around Saturn. North on Titan is up and rotated 40 degrees to the left. Images taken using red, green and blue spectral filters were combined to create this natural-color view. The images were taken with the Cassini spacecraft narrow-angle camera on Nov. 3, 2013. The view was acquired at a distance of approximately 2.421 million miles (3.896 million kilometers) from Titan. Image scale is 14 miles (23 kilometers) per pixel. http://photojournal.jpl.nasa.gov/catalog/PIA17180
These maps of the near and far side of the moon show gravity gradients as measured by NASA GRAIL mission. Red and blue areas indicate stronger gradients due to underlying mass anomalies.

Two different seasons on Titan in different hemispheres can be seen in this image. The moon northern half appears slightly darker than the southern half in this view taken in visible blue light by NASA Cassini spacecraft.

NASA Voyager 2 took this true color photograph of Saturn on July 21, 1981. The moons Rhea and Dione appear as blue dots to the south and southeast of Saturn, respectively.
This crescent view of Earth Moon in infrared, blue-green, and red wavelengths comes from a camera test by NASA Mars Reconnaissance Orbiter spacecraft on its way to Mars.

This map shows predicted heat flow at the surface of Jupiter moon Io from two tidal-heating models. Red indicates areas where more heat is expected; blue where less heat is expected.

Two different instruments on NASA Cassini spacecraft combined their observations to create a more detailed portrait of the Hotei Regio area on Saturn moon Titan. Blue lines on top show the location of channels that stand out in the bottom of image.

These maps of the moon show the Bouguer gravity anomalies as measured by NASA GRAIL mission. Red areas have stronger gravity, while blue areas have weaker gravity.
A 300-mile-long linear gravity anomaly on the far side of the moon has been revealed by gravity gradients measured by NASA GRAIL mission. GRAIL data are shown on the left, with red and blue corresponding to stronger gravity gradients.

A science instrument flying aboard the next delivery for NASA’s CLPS (Commercial Lunar Payload Services) initiative could help improve our understanding of the Moon. The Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity, or LISTER, is one of 10 payloads set to be carried to the Moon by the Blue Ghost 1 lunar lander in 2025. Developed jointly by Texas Tech University and Honeybee Robotics, LISTER’s planned mission is to measure the flow of heat from the Moon’s interior using a specialized drill. Investigations and demonstrations, such as LISTER, launched on CLPS flights will help NASA study Earth’s nearest neighbor under Artemis and pave the way for future crewed missions on the Moon. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the development and operations for seven of the 10 CLPS payloads that will be carried on Firefly’s Blue Ghost lunar lander.

Pluto's haze layer shows its blue color in this picture taken by the New Horizons Ralph/Multispectral Visible Imaging Camera (MVIC). The high-altitude haze is thought to be similar in nature to that seen at Saturn's moon Titan. The source of both hazes likely involves sunlight-initiated chemical reactions of nitrogen and methane, leading to relatively small, soot-like particles (called tholins) that grow as they settle toward the surface. This image was generated by software that combines information from blue, red and near-infrared images to replicate the color a human eye would perceive as closely as possible. http://photojournal.jpl.nasa.gov/catalog/PIA19964

In this lunar eclipse viewed from Merritt Island, Fla., at 11:55 p.m., the full moon takes on a dark red color because it is being lighted slightly by sunlight passing through the Earth's atmosphere. This light has the blue component preferentially scattered out (this is also why the sky appears blue from the surface of the Earth), leaving faint reddish light to illuminate the Moon during the eclipse. Eclipses occur when the Sun, Earth and Moon line up. They are rare because the Moon usually passes above or below the imaginary line connecting Earth and the Sun. The Earth casts a shadow that the Moon can pass through -when it does, it is called a lunar eclipse

A science instrument flying aboard the next delivery for NASA’s CLPS (Commercial Lunar Payload Services) initiative is expected to significantly expand our knowledge of the Moon. Next Generation Lunar Retroreflector, or NGLR-1, is one of 10 payloads set to be carried to the Moon by the Blue Ghost 1 lunar lander in 2025. Developed by the University of Maryland in College Park, NGLR-1 is designed to reflect very short laser pulses from Earth-based lunar laser ranging observatories using a retroreflector, or a mirror designed to reflect the incoming light back in the same incoming direction. Investigations and demonstrations, such as NGLR-1, launched on CLPS flights will help NASA study Earth’s nearest neighbor under Artemis and pave the way for future crewed missions on the Moon. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the development for seven of the 10 CLPS payloads that will be carried on Firefly’s Blue Ghost lunar lander.

Viewed from Merritt Island, Fla., at 10:59 p.m. EST, the full moon, traveling west to east, is three-quarters of the way into the Earth's shadow during a lunar eclipse. Eclipses occur when the Sun, Earth and Moon line up. They are rare because the Moon usually passes above or below the imaginary line connecting Earth and the Sun. The Earth casts a shadow that the Moon can pass through -when it does, it is called a lunar eclipse. They can only occur when the moon is "full."

Slipping into shadow, the south polar vortex at Saturn's moon Titan still stands out against the orange and blue haze layers that are characteristic of Titan's atmosphere. Images like this, from NASA's Cassini spacecraft, lead scientists to conclude that the polar vortex clouds form at a much higher altitude -- where sunlight can still reach -- than the lower-altitude surrounding haze. This view looks towards the trailing hemisphere of Titan (3,200 miles or 5,150 kilometers across). North on Titan is up and rotated 17 degrees to the left. Images taken using red, green and blue spectral filters were combined to create this natural-color view. The image was taken with the Cassini spacecraft narrow-angle camera on July 30, 2013. The view was acquired at a distance of approximately 895,000 miles (1.441 million kilometers) from Titan.

A technology demonstration flying aboard the next delivery for NASA’s CLPS (Commercial Lunar Payload Services) initiative could change how research teams collect and study soil and rock samples on other planetary bodies. Lunar PlanetVac, or LPV, is one of 10 payloads set to be carried to the Moon by the Blue Ghost 1 lunar lander in 2025. Developed by Honeybee Robotics, a Blue Origin company of Altadena, California, LPV is designed to, essentially, operate as a vacuum cleaner with a pneumatic, compressed gas-powered sample acquisition and delivery system to efficiently collect and transfer lunar soil from the surface to other science instruments or sample return containers. Investigations and demonstrations, such as LPV, launched on CLPS flights will help NASA study Earth’s nearest neighbor under Artemis and pave the way for future crewed missions on the Moon. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the development for seven of the 10 CLPS payloads that will be carried on Firefly’s Blue Ghost lunar lander.

A paddlewheeler makes its way up the Mississippi River as the moon rises over New Orleans on Sunday evening, August 22, 2021. The August Sturgeon Moon, which was also a rare Blue Moon, was full at 7:02 A.M. local time Sunday but the nearly full moon still put on a show when it rose over New Orleans later that evening. New Orleans is home to the NASA Michoud Assembly Facility where the core stage of the Space Launch System that will return people to the moon is being built. Image credit: NASA/Michael DeMocker

A brilliant blue sky serves as the backdrop for a panoramic view of the iconic Vehicle Assembly Building, mobile launcher at left, and Launch Control Center at right, at NASA's Kennedy Space Center in Florida. These facilities are being upgraded for NASA's Space Launch System and Orion spacecraft for launches to deep space destinations, including the Moon, Mars and beyond.

iss060e002090 (June 29, 2019) --- The Earth's limb and the atmospheric glow highlight the thin blue atmosphere back lit by the Sun's rays during a period between night and day. The light of the moon and the starry Milky Way drape the background as the International Space Station orbited 257 miles above the Pacific Ocean between Hawaii and Mexico.
This composite image of Earth and its moon, as seen from Mars, combines the best Earth image with the best moon image from four sets of images acquired on Nov. 20, 2016, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. Each was separately processed prior to combining them so that the moon is bright enough to see. The moon is much darker than Earth and would barely be visible at the same brightness scale as Earth. The combined view retains the correct sizes and positions of the two bodies relative to each other. HiRISE takes images in three wavelength bands: infrared, red, and blue-green. These are displayed here as red, green, and blue, respectively. This is similar to Landsat images in which vegetation appears red. The reddish feature in the middle of the Earth image is Australia. Southeast Asia appears as the reddish area (due to vegetation) near the top; Antarctica is the bright blob at bottom-left. Other bright areas are clouds. These images were acquired for calibration of HiRISE data, since the spectral reflectance of the Moon's near side is very well known. When the component images were taken, Mars was about 127 million miles (205 million kilometers) from Earth. http://photojournal.jpl.nasa.gov/catalog/PIA21260

iss071e067226_stk (5/8/2024) --- NASA astronaut Matt Dominick aboard space station captured this waxing lunar crescent illuminated by the Sun. The rest of the Moon dimly glows by earthshine when sunlight reflects off Earth onto the Moon. Scientists track the Earth’s brightness, or albedo, via this phenomenon. This photo also shows a cross-section of Earth’s atmospheric layers, including the orange troposphere nearest to the surface and the thicker, light-blue stratosphere above that.
