Everyone you love in one photo ❤️ Before its imaging camera was turned off, NASA's Voyager 1 took this iconic photo known as the "Pale Blue Dot" #OTD in 1990. In it, Earth is visible as a miniscule speck in the inky darkness.
The Pale Blue Dot is a photograph of Earth taken Feb. 14, 1990, by NASA\u2019s Voyager 1 at a distance of 3.7 billion miles (6 billion kilometers) from the Sun. The image inspired the title of scientist Carl Sagan's book, \"Pale Blue Dot: A Vision of the Human Future in Space,\" in which he wrote: \"Look again at that dot. That's here. That's home. That's us.\" This image, \u201CPale Blue Dot Revisited,\u201D was created in 2020 for the 30th anniversary of the iconic picture. The updated version used modern image-processing software and techniques to revisit the well-known Voyager view, while attempting to respect the original data and intent of those who planned the images.

The #NISAR mission is one step closer to liftoff! This NASA-ISRO satellite, designed to monitor Earth’s changing ecosystems, land surfaces, and ice, has safely arrived at India’s Satish Dhawan Space Centre. Launch is targeted for July. Details: go.nasa.gov/45Gdytd
The lid of a specialized container is lifted to reveal NISAR, the Earth-observing radar satellite jointly developed by NASA and the Indian Space Research Organisation (ISRO), shortly after the spacecraft’s arrival at ISRO’s Satish Dhawan Space Centre in Sriharikota on India’s southeastern coast on May 16, 2025. The container is white and is being lifted above the spacecraft that is covered in silver blanketing, People in blue frocks stand to the right of the container. The image is slightly tinted in color because of fluorescent lights in the facility.

During its early years, our universe was immersed in a fog of neutral hydrogen gas, but today this gas is ionized. Until now, astronomers have wondered what objects caused this transformation. Using @NASAWebb data, a team of astronomers have identified dozens of small galaxies that played a starring role in shaping our universe into the one we know today. More: go.nasa.gov/4kX9sky

Have you seen the latest images of solar eruptions from @NASA's PUNCH mission? Using the mission’s highly sensitive, wide-field instruments, we’re able to capture a big-picture view of coronal mass ejections (CMEs) as they evolved and raced through the inner solar system in much greater detail than previously possible. The data from these images are helping scientists better understand space weather and its impact. More: go.nasa.gov/4kzAHBV

This month’s #NASAScience image features Cassiopeia A, one of the most studied supernova remnants. Using data from @chandraxray and @NASAWebb, researchers have uncovered previously unseen structures within the stellar debris, offering new insights into the complex aftermath of a massive star’s explosion.

A circular-shaped nebula with a complex structure. On the circle’s exterior, particularly on the left side of the image, are curtains of material glowing orange like fire. Interior to this outer shell is a ring of mottled filaments in bright pink, studded with clumps and knots. A greenish loop extends from the upper right of the ring into the central cavity. Translucent wisps of blue, green, and red appear throughout the image.

Where did Mars' water go? And why? These questions have long puzzled scientists. Now, after a decade of searching, @NASAMars’ MAVEN has made the first direct observation of an elusive atmospheric escape process known as sputtering, offering new insight into the Red Planet’s mysterious water loss. go.nasa.gov/3Z4oUTB

On the ISS, bubbles don’t rise, tools float away and air doesn’t move on its own, so experiments in space need to be reimagined from the ground up. A NASA scientist explains how we do research in zero gravity. Learn more about science on @Space_Station: go.nasa.gov/3HcDxyd

Did you know that changes in nearby tree leaves can indicate when a volcano becomes more active and might erupt? New research from @NASA and the Smithsonian Institution suggests that we can now detect these changes from space. More: go.nasa.gov/3HaEZAY
