Partial Solar Eclipse over U.S. State of Maine

Partial Solar Eclipse over U.S. State of Maine

On March 29, 2025, the Moon passed in front of and partially blocked the Sun, casting a shadow on parts of the Earth's Northern Hemisphere. The central part of the Moon’s shadow, where the Sun appears completely blocked, missed Earth, so no one was able to see a total solar eclipse this time. 


This is a view of the partial eclipse from Monticello. It is a town in Aroostook County, Maine, United States, on the northern branch of the Meduxnekeag River.

The Crew-11 mission patch embodies teamwork, exploration, and the deep connections that bind us—across nations, agencies, and families. Shades of white, red, and blue pay tribute to the flags of the three nations represented by the crew, while three gold stars symbolize the unity of our three space agencies working together in pursuit of discovery. At the heart of the design, two radiant sunbeams form the number “11” illuminating a blue circle—a subtle nod to Voyager’s Pale Blue Dot image, reminding us of the fragile unity of our shared home. This vision of Earth is reflected in the dragon’s eye, reinforcing our focus on exploration and the perspective gained from space. The dragon, evoking the heraldry of family crests, stands as a guardian of our mission and legacy. Within the stars, we honor the children of the crew, a reminder of the generations inspired by human spaceflight. Encircling it all, a red flame represents both the power of launch and the plasma of reentry, symbolizing the full journey—our departure from Earth, our work aboard the International Space Station, and our safe return home. Crew-11: Together, we rise.


As part of NASA’s SpaceX Crew-11 mission, four crew members from three space agencies will launch in the coming months to the International Space Station for a long-duration science expedition aboard the orbiting laboratory.

NASA astronauts Commander Zena Cardman and Pilot Mike Fincke, Japan Aerospace Exploration Agency (JAXA) astronaut Mission Specialist Kimiya Yui, and Roscosmos cosmonaut Mission Specialist Oleg Platonov of Russia will join crew members aboard the space station no earlier than July 2025.

The flight is the 11th crew rotation with SpaceX to the station as part of NASA’s Commercial Crew Program. The crew will conduct scientific investigations and technology demonstrations to help prepare humans for future missions to the Moon, as well as benefit people on Earth.

Cardman previously was assigned to NASA’s SpaceX Crew-9 mission, and Fincke previously was assigned to NASA’s Boeing Starliner-1 mission. NASA decided to reassign the astronauts to Crew-11 in overall support of planned activities aboard the International Space Station. Cardman carries her experience training as a commander on Dragon spacecraft, and Fincke brings long-duration spaceflight experience to this crew complement.

Selected as a NASA astronaut in 2017, Cardman will conduct her first spaceflight. The Williamsburg, Virginia, native holds a bachelor’s degree in Biology and a master’s in Marine Sciences from the University of North Carolina at Chapel Hill. At the time of selection, she had begun pursuing a doctorate in Geosciences. Cardman’s research in geobiology and geochemical cycling focused on subsurface environments, from caves to deep sea sediments. Since completing initial training, Cardman has supported real-time station operations and lunar surface exploration planning.

NASA astronaut Zena Cardman biography:

This will be Fincke’s fourth trip to the space station, having logged 382 days in space and nine spacewalks during Expedition 9 in 2004, Expedition 18 in 2008, and STS-134 in 2011, the final flight of space shuttle Endeavour. Throughout the past decade, Fincke has applied his expertise to NASA’s Commercial Crew Program, advancing the development and testing of the SpaceX Dragon and Boeing Starliner toward operational certification. The Emsworth, Pennsylvania, native is a distinguished graduate of the United States Air Force Test Pilot School and holds bachelors’ degrees from the Massachusetts Institute of Technology, Cambridge, in both Aeronautics and Astronautics, as well as Earth, Atmospheric and Planetary Sciences. He also has a master’s degree in Aeronautics and Astronautics from Stanford University in California. Fincke is a retired U.S. Air Force colonel with more than 2,000 flight hours in more than 30 different aircraft.

NASA astronaut Mike Fincke biography:

With 142 days in space, this will be Yui’s second trip to the space station. After his selection as a JAXA astronaut in 2009, Yui flew as a flight engineer for Expedition 44/45 and became the first Japanese astronaut to capture JAXA’s H-II Transfer Vehicle. In addition to constructing a new experimental environment aboard Kibo, he conducted a total of 21 experiments for JAXA. In November 2016, Yui was assigned as chief of the JAXA Astronaut Group. He graduated from the School of Science and Engineering at the National Defense Academy of Japan in 1992. He later joined the Air Self-Defense Force at the Japan Defense Agency (currently Ministry of Defense). In 2008, Yui joined the Air Staff Office at the Ministry of Defense as a lieutenant colonel.

JAXA astronaut Kimiya Yui biography:

The Crew-11 mission will be Platonov’s first spaceflight. Before his selection as a cosmonaut in 2018, Platonov earned a degree in Engineering from Krasnodar Air Force Academy in Aircraft Operations and Air Traffic Management. He also earned a bachelor’s degree in State and Municipal Management in 2016 from the Far Eastern Federal University in Vladivostok, Russia. Assigned as a test cosmonaut in 2021, he has experience in piloting aircraft, zero gravity training, scuba diving, and wilderness survival.

For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA’s Artemis campaign is underway at the Moon, where the agency is preparing for future human exploration of Mars.

The Lyra Constellation

The Lyra Constellation


Lyra (Latin for 'lyre', from Ancient Greek: λύρα) is a small constellation. It is one of the 48 listed by the 2nd century astronomer Ptolemy. This is one of the modern 88 constellations recognized by the International Astronomical Union (IAU). 

Note: The lyre is a stringed musical instrument that originated in ancient Greece. It typically features a yoke with two arms and a crossbar, with strings running from a tailpiece to the crossbar, and is primarily played by plucking the strings.

Lyra was often represented on star maps as a vulture or an eagle carrying a lyre, and hence is sometimes referred to as Vultur Cadens or Aquila Cadens ("Falling Vulture" or "Falling Eagle"), respectively. 

Beginning at the north, Lyra is bordered by Draco, Hercules, Vulpecula, and Cygnus. Lyra is nearly overhead in temperate northern latitudes shortly after midnight at the start of summer. From the equator to about the 40th parallel south it is visible low in the northern sky during the same (thus winter) months.


Vega, Lyra's brightest star, is one of the brightest stars in the night sky, and forms a corner of the famed Summer Triangle asterism. Beta Lyrae is the prototype of a class of binary stars known as Beta Lyrae variables. These binary stars are so close to each other that they become egg-shaped and material flows from one to the other. Epsilon Lyrae, known informally as the Double Double, is a complex multiple star system. Lyra also hosts the Ring Nebula, the second-discovered and best-known planetary nebula.

Expedition 72: New Crew Members at Work & More | International Space Station

Expedition 72: New Crew Members at Work & More | International Space Station

NASA astronaut and Expedition 72 Flight Engineer Nichole Ayers inserts a cryogenic storage unit, called a dewar, containing blood samples collected from a crew member into a science freezer for preservation and later analysis. The Minus Eighty-Degree Laboratory Freezer for International Space Station, or MELFI, is a research freezer that maintains experiment samples at ultra-cold temperatures in microgravity.
NASA astronaut Nichole Ayers: "More science! After completing a blood draw (we are our own phlebotomists up here), we spun the tubes in a centrifuge and then put them in the MELFI (Minus Eighty Degree Laboratory Freezer) for later return to the ground. 
This study is looking at bone structure pre- and post-mission, as well as bone markers in the blood to help build a digital twin model that can aid in predictions of future bone evolution."
NASA astronaut and Expedition 72 Flight Engineer Nichole Ayers works inside the International Space Station's Kibo laboratory module loading software onto an Astrobee robotic free-flyer. The software is part of a technology investigation demonstrating an adaptor for docking and close approach sensing to connect both active and passive objects in space. Results may enable applications, such as satellite servicing, orbital refueling, spacecraft repair and upgrade, and in-orbit manufacturing.

NASA's Space to Ground: Transitional Period | Week of March 28, 2025

NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station. On Friday, March 28, 2025, at 6:55 a.m. EDT, the S.S. Richard “Dick” Scobee Northrop Grumman Cygnus spacecraft was released from the Canadarm2 robotic arm. It earlier detached Cygnus from the Earth-facing port of the International Space Station’s Unity module. At the time of release, the station was flying about 260 miles over the Pacific Ocean. 

The Cygnus spacecraft successfully departed the space station more than seven and a half months after arriving at the microgravity laboratory to deliver about 8,200 pounds of supplies, scientific investigations, commercial products, hardware, and other cargo for NASA. 

Following a deorbit engine firing on Sunday, March 30, Cygnus will begin a planned destructive re-entry, in which the spacecraftfilled with trash packed by the station crewwill safely burn up in Earth’s atmosphere.

Close-up | Jetting into Space: Protostars HOPS 150 & 153 in Orion | Hubble

Close-up | Jetting into Space: Protostars HOPS 150 & 153 in Orion | Hubble


This NASA/European Space Agency Hubble Space Telescope picture peers into the dusty recesses of the nearest massive star-forming region to Earth, the Orion Nebula. Just 1,300 light-years away, the Orion Nebula is visible to the naked eye below the three stars that form the ‘belt’ in the constellation Orion. The nebula is home to hundreds of newborn stars, including the subject of this imagethe protostars HOPS 150 and HOPS 153.

These protostars get their names from the Herschel Orion Protostar Survey. It was carried out with the European Space Agency’s Herschel Space Observatory. The object that can be seen in the upper-right corner of this image is HOPS 150. It is a binary system, two young protostars orbiting each other. Each has a small, dusty disc of material surrounding it that it is feeding from. The dark line that cuts across the bright glow of these protostars is a cloud of gas and dust, over 2,000 times wider than the distance between Earth and the Sun, falling in on the pair of protostars. Based on the amount of infrared versus other wavelengths of light HOPS 150 is emitting, the protostars are mid-way down the path to becoming mature stars.

Extending across the left side of the image is a narrow, colorful outflow called a jet. This jet comes from the nearby protostar HOPS 153, out of frame. HOPS 153 is a significantly younger stellar object than its neighbor, still deeply embedded in its birth nebula and enshrouded by a cloud of cold, dense gas. While Hubble cannot penetrate this gas to see the protostar, the jet HOPS 153 has emitted is brightly visible as it plows into the surrounding gas and dust of the Orion Nebula.

The transition from tightly swaddled protostar to fully fledged star will dramatically affect HOPS 153’s surroundings. As gas falls onto the protostar, its jets spew material and energy into interstellar space, carving out bubbles and heating the gas. By stirring up and warming nearby gas, HOPS 153 may regulate the formation of new stars in its neighborhood and even slow its own growth.

Image Description: An area in the Orion nebula filled with dark, puffy clouds. On the left side a large area of clouds, crossed by a dark bar, is lit up in red and whitish colors by a protostar within. At the other side a large jet of material ejected by the protostar appears, made of thin, wispy, blue and pink clouds. A couple of foreground stars shine brightly in front of the nebula.

Finding Clues in Ancient Dead Star's Ruins | NASA's Chandra X-ray Observatory

Finding Clues in Ancient Dead Star's Ruins NASA's Chandra X-ray Observatory

People often think about archaeology happening deep in jungles or inside ancient pyramids. However, a team of astronomers has shown that they can use stars and the remains they leave behind to conduct a special kind of archaeology in space.

Mining data from NASA’s Chandra X-ray Observatory, the team of astronomers studied the relics that one star left behind after it exploded. This “supernova archaeology” result uncovers important clues about a star that self-destructed—probably more than a million years ago.

Today, the system called GRO J1655-40 contains a black hole with nearly seven times the mass of the Sun and a star with about half as much mass. However, this was not always the case.

Originally GRO J1655-40 had two shining stars. The more massive of the two stars, however, burned through all of its nuclear fuel and then exploded in what astronomers call a supernova. The debris from the destroyed star then rained onto the companion star in orbit around it.

With its outer layers expelled, including some striking its neighbor, the rest of the exploded star collapsed onto itself and formed the black hole that exists today. Over time, the black hole and companion star moved closer. When the separation became small enough, the black hole, with its strong gravitational pull, began pulling matter from its companion, wrenching back some of the material its exploded parent star originally deposited.

While most of this material sank into the black hole, a small amount of it fell into a disk that orbits around the black hole. Through the effects of powerful magnetic fields and friction in the disk, material is being sent out into interstellar space in the form of powerful winds.

This is where the X-ray archaeological hunt enters the story. Astronomers used Chandra to observe the GRO J1655-40 system in 2005 when it was particularly bright in X-rays. Chandra detected signatures of individual elements found in the black hole’s winds by getting detailed spectra—giving X-ray brightness at different wavelengths—embedded in the X-ray light.

The team of astronomers digging through the Chandra data were able to reconstruct key physical characteristics of the star that exploded from the clues imprinted in the X-ray light by comparing the spectra with computer models of stars that explode as supernovae. They discovered that the long-gone star destroyed in the supernova was about 25 times the mass of the Sun. It was also much richer in elements heavier than helium in comparison with the Sun.

Look for more supernova archaeology stories with Chandra in the future!

Close-up: Two Galaxies and an Einstein Ring | Webb Telescope

Close-up: Two Galaxies and an Einstein Ring | Webb Telescope

This new NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope picture features a rare cosmic phenomenon called an Einstein ring. What at first appears to be a single, strangely shaped galaxy is actually two galaxies that are separated by a large distance. The closer foreground galaxy sits at the center of the image, while the more distant background galaxy appears to be wrapped around the closer galaxy, forming a ring. 

Einstein rings occur when light from a very distant object is bent (or ‘lensed’) about a massive intermediate (or ‘lensing’) object. This is possible because spacetime, the fabric of the Universe itself, is bent by mass, and therefore light travelling through space and time is bent as well. This effect is much too subtle to be observed on a local level, but it sometimes becomes clearly observable when dealing with curvatures of light on enormous, astronomical scales, such as when the light from one galaxy is bent around another galaxy or galaxy cluster.

When the lensed object and the lensing object line up just so, the result is the distinctive Einstein ring shape. It appears as a full circle (as seen here) or a partial circle of light around the lensing object, depending on the precision of the alignment. Objects like these are the ideal laboratory in which to research galaxies too faint and distant to otherwise see.

The lensing galaxy at the center of this Einstein ring is an elliptical galaxy, as can be seen from the galaxy’s bright core and smooth, featureless body. This galaxy belongs to a galaxy cluster named SMACSJ0028.2-7537. The lensed galaxy wrapped around the elliptical galaxy is a spiral galaxy. Even though its image has been warped as its light travelled around the galaxy in its path, individual star clusters and gas structures are clearly visible.

The Webb data used in this image were taken as part of the Strong Lensing and Cluster Evolution (SLICE) survey (program 5594), which is led by Guillaume Mahler at University of Liège in Belgium, and consists of a team of international astronomers. This survey aims to trace 8 billion years of galaxy cluster evolution by targeting 182 galaxy clusters with Webb’s Near-InfraRed Camera instrument. This image also incorporates data from two of the NASA/European Space Agency Hubble Space Telescope’s instruments, the Wide Field Camera 3 and the Advanced Camera for Surveys.

Image Description: In the center is an elliptical galaxy, seen as an oval-shaped glow around a small bright core. Around this is wrapped a broad band of light, appearing like a spiral galaxy stretched and warped into a ring, with bright blue lines drawn through it where the spiral arms have been stretched into circles. A few distant objects are visible around the ring on a black background.
