The Pie Master

Earth is constantly immersed in a stream of charged particles flowing outward from the Sun: the solar wind. When it encounters Earth’s magnetic field, it creates a massive shock wave in space that can be chaotic or calm. Help scientists understand why as part of NASA's new Shock Detectives citizen science project: go.nasa.gov/3RyRFqt

The @SpaceX Dragon delivered a host of space experiments on May 17, 2026, the crew is now working on. Some of the new studies will take advantage of weightlessness to develop advanced treatments for Earth ailments and space-caused conditions. More... nasa.gov/blogs/spacesta…

Who's afraid of Zwan-Wolf? NASA's MAVEN orbiter surprised scientists by observing the Zwan-Wolf effect, an atmospheric phenomenon never before seen at the Red Planet. The discovery expands our understanding of space weather at Mars, essential knowledge for ongoing exploration. More: go.nasa.gov/42GRxaY

#OTD in 2009, the fifth and final Hubble Servicing Mission (STS-125), released Hubble to continue observing our universe. The STS-125 crew were the last people to touch Hubble, having completed five spacewalks during the mission.

It’s all in your perspective! We are seeing just the edge of this pencil-thin galaxy known as NGC 4565. If we could just change our angle, though, we would see it has grand spiral arms just like our own Milky Way. #MondayMotivation

And the beat goes on... NASA spacecraft tracked a record-breaking 19-day radio burst from the Sun in August. As it rang out, the Sun's rotation brought the burst into view of four different spacecraft, which were spread across the inner solar system. go.nasa.gov/4ddlBkp

Hello Mars, goodbye Mars 👋 NASA’s #MissionToPsyche spacecraft was speeding by the Red Planet on May 15 when it snapped this rare, crescent view of Mars. The successful flyby flung the Psyche spacecraft toward its final destination: the metal-rich asteroid Psyche. 1/2

@MaxParx92 @JoeDirt34272 @clarke_san18335 @airandspace It's already occurred, 9 Apollo Missions to the Moon, 6 Lunar Landings, 0 fakery. Multiple countries monitored the missions with independent instruments, some with adversarial interests to those of the United States. They would have had every incentive to expose it, but didn't.🤔

@JoeDirt34272 @clarke_san18335 @airandspace We'll talk about that in 2 years. My bet is Artemis will not land man on Moon not in 2028, not in 2030, etc. But you'll always believe it's going to happen IN FUTURE 😉

On this day in 1972, Apollo 16 lunar module "Orion" landed on the Moon in the Descartes Highlands. John Young (seen here) and Charles Duke were on the lunar surface for 71 hours and two minutes, while TK Mattingly circled the Moon in the command module "Casper."

What does it take to plan high-stakes missions that can take years to complete? Darius Yaghoubi, deputy chief engineer for NASA’s Planetary Missions Program Office at #NASAMarshall, talks about those challenges in this episode of Small Steps, Giant Leaps: go.nasa.gov/42DcjrP

Every dot, a world 🌌 Explore the sky as seen by our exoplanet hunter TESS. Between April 2018, when TESS began its work, and September 2025, the spacecraft identified 679 confirmed (blue) and 5,165 candidate (orange) planets beyond our solar system. go.nasa.gov/4wtcAuX

POV: You’re coming home after a journey around the Moon. 🌕 Before reentering Earth’s atmosphere at the end of Artemis II, the Orion spacecraft’s crew module — carrying the astronauts — separated from the service module that provided propulsion and power throughout the mission.

Westerlund 2 is a young cluster of thousands of stars located about 20,000 light-years from Earth. This close-up image, roughly 12 light-years across, combines observations from NASA's Chandra X-ray Observatory & @NASAWebb.✨

100 million light-years down the river... 🚣 Nestled in the "Celestial River" constellation of Eridanus, the galaxy NGC 1266 previously experienced a major burst of star formation, likely triggered by a merger with another galaxy ~500 million years ago: go.nasa.gov/4wy8xxs

"Liftoff for the final launch of Endeavour!" 15 years ago today, Endeavour launched into space for its 25th and final time. STS-134, the penultimate mission of NASA's Space Shuttle program, delivered the Alpha Magnetic Spectrometer-2 and critical supplies to the space station.

Your order is out for delivery 🚀 At 6:05pm ET (2205 UTC) on May 15, our next @SpaceX resupply mission lifted off to the @Space_Station and will reach its destination on May 17. go.nasa.gov/4eKxaRk

.@NASA and @SpaceX now target no earlier than 6:50pm ET Wednesday, May 13, for Dragon's launch to resupply to the Exp 74 crew. Tuesday’s launch slipped due to forecasted inclement weather around the launch site in Florida. More... go.nasa.gov/4tPvpGx

Smile, our mission to study Earth's response to solar winds, has arrived at the launch pad. It is now positioned atop Vega-C’s fourth stage ahead of the 19 May launch #VV29 🚀 🔗esa.int/Science_Explor…

IC 486 lies on the edge of the constellation Gemini, around 380 million light-years from Earth. This barred spiral galaxy features a bright central bar-shaped structure from which its spiral arms unfurl, wrapping around the core. More on this @NASAHubble image >> go.nasa.gov/4dBsWu5

Let's get weird with it. We've confirmed more than 6,000 exoplanets, planets beyond our solar system. Some orbit with the same kind constantly facing their star; some don't orbit a star at all. But those are just the start. Meet some of @NASAHubble's weirdest exoplanet finds.
