Hubble’s Highlights from its 36th Year in Orbit | Goddard Space Flight Center

The Hubble Space Telescope celebrated its 36th year in orbit by premiering a stunning new Hubble image of the Trifid Nebula. Even after all these years, Hubble continues to uncover the mysteries of the universe. These are a few science achievements from Hubble’s latest year in orbit.

The Hubble Space Telescope has taken over 1.7 million observations to date. Almost 29,000 astronomers have published peer-reviewed science papers using Hubble data collected over the telescope’s 36-year lifetime, resulting in more than 23,000 publications, with almost 1100 in 2025 alone. Since 2022, researchers have regularly combined Hubble’s observations with those from the James Webb Space Telescope to push opportunities for discovery further.

The Hubble Space Telescope is a project of international cooperation between the European Space Agency (ESA) and NASA.

Shenzhou-21 Astronauts Send Orbital Blessings to All for 'Space Day' in China

Shenzhou-21 Astronauts Send Orbital Blessings to All for 'Space Day' in China


As China celebrated its 11th Space Day on Friday, April 24, 2026, the Shenzhou-21 crew aboard the country's space station sent their blessings, wishing for a promising future for the nation's space endeavors.

The Shenzhou-21 crew members, comprised of mission commander Zhang Lu and astronauts Wu Fei and Zhang Hongzhang, were sent to space from the Jiuquan Satellite Launch Center in northwest China on October 31, 2025 for a six-month mission.

"Upon the 11th Space Day, I wish for continued prosperity and success to our motherland's space program, and I hope that everyone who harbors a dream of space exploration will bravely set out toward the stars and the vast ocean of space. This year marks the 70th anniversary of the founding of China's space program. From the moment the melody of 'The East Is Red' echoed across the universe to the present day when the Chinese space station soars through the heavens, we astronauts are not only witnesses to history but also participants of history. The Tianhe core module has been in orbit operation for five years. Living in a space home built by the Chinese people, we feel a deep sense of security. We are immensely happy to be able to contribute to the significant development of China's space program," said astronaut Zhang Lu.

"Hello everyone, I'm astronaut Wu Fei. In October 2003, the return capsule of the Shenzhou-5 spacecraft landed on the grasslands of Siziwang Banner in Inner Mongolia. Back then, as a child, I wrote five words on a piece of paper: 'I will go to space'. Now, the boy who once gazed admiringly at the stars has realized his dream. Working and living at the Chinese space station, I understand even more clearly that the curiosity in children's eyes is the most precious fuel for the space industry. The baton of China's space program will eventually be passed into your hands. I hope you will keep the crave for exploring the unknown. Dreams are never distant starlight; they are the result of perseverance, one step at a time. Let us chase our dreams in our youth, living up to the expectations of our era and our motherland," said astronaut Wu Fei.

"Taking care of plants as they thrive, helping mice complete their wondrous journey in space, and combining scientific ideals with the dream of flying to the heavens, I find every day in space deeply meaningful. As space explorers of the new era, we are fulfilling our aspirations through our joint endeavors to build the glory of China's space program. The future holds great promise, and let us together put the footprints of the Chinese people into the farther reaches of the cosmos," said astronaut Zhang Hongzhang.

In 2016, April 24 was chosen as the Space Day of China to mark the launch of the country's first satellite "Dongfanghong-1" into space on April 24, 1970.

Crew Thanks Public Supporters Worldwide | NASA Artemis II Moon Mission

Crew Thanks Public Supporters Worldwide | NASA Artemis II Moon Mission

"A thank you, in their own words . . ." 🫶

The Artemis II crew wanted to share their thanks to everyone that followed along during their journey, and to remind us that there is more human exploration coming.

The first crewed test flight of NASA’s Artemis program lifted off from Launch Pad 39B at the agency’s Kennedy Space Center in Florida on April 1, 2026, carrying the first astronauts to travel to the Moon in more than half a century. 

During their nearly 10-day mission, the crew completed a record-setting lunar flyby, taking them 252,756 miles at their farthest distance from Earth and 4,067 miles above the lunar surface at their closest approach. 

Artemis II splashed down at 8:07 p.m. April 10 in the Pacific Ocean off the coast of San Diego. Following splashdown and recovery, the four crew members underwent post-mission medical evaluations before returning to shore and boarding an aircraft bound for Houston. Upon arrival, the crew was welcomed by and reunited with their families, friends, and agency workforce. The crew now will begin their postflight reconditioning, medical and human performance evaluations, and lunar science debriefs.

Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.

China to Make New Breakthroughs in Space Exploration in 2026: Aerospace Scientists

China to Make New Breakthroughs in Space Exploration in 2026: Aerospace Scientists

China is set to make new breakthroughs in space exploration in the near future, said leading researchers at the China Aerospace Science and Technology Corporation (CASC).

Among the most critical space missions scheduled this year and next, China will launch its latest lunar probe and its Hubble-class Xuntian Space Telescope, as well as hundreds of satellites to support its Guowang broadband constellation.

"This year, we will send the Chang'e-7 probe to the Moon. There will be another space station mission next year, which might be the most valuable space station project in the history of science, and it will be launched by the Long March-5B rocket," said rocket designer Feng Shaowei from China Academy of Launch Vehicle Technology of the CASC.

Chang'e-7 will explore the Moon's south pole, focusing on locating water ice and other resources in anticipation of a crewed lunar landing in the future.

Meanwhile, China's Tiangong space station will continue to carry out its wide-ranging experimental research, both inside the station's laboratories and outside its walls, with the use of robotic arms. These arms are often used for research in exposing materials to space, but increasingly, they are also used to carry out complex logistical tasks, from collecting cargo spacecraft to rearranging the station's solar arrays.

"In the future, our space station may see the addition of more modules to expand our application capabilities. At the same time, we will enhance the capabilities of our robotic arms, enabling them to perform even more complex tasks," said Hou Yongqing, a space station systems expert from China Academy of Space Technology of the CASC.

According to these aerospace scientists, the coming years could even see China become the second country ever to put astronauts on the moon.

"One thing we look forward to is seeing the new generation of crewed spacecraft flying into space, building a brand-new round-trip transportation platform between Earth and space for astronauts. Our crewed lunar exploration project has also been making steady progress in recent years. In the near future, we will witness the footprints of the Chinese people left on the lunar surface," said Shao Limin, an expert in crewed spacecraft systems of China Academy of Space Technology.

Beyond advancing our understanding of the solar system, China's space programs are also highly consequential for life on Earth. The country's BeiDou Navigation Satellite System, for instance, is increasingly used in the development of emerging industries.

"The goals for the next generation of BeiDou Navigation Satellite System are very clear. First, we will further improve the accuracy of positioning services to meet the demands of artificial intelligence, autonomous driving and other future technologies. Second, we aim to lower the barrier for users accessing the system, making it more cost-effective and efficient," said Xie Jun, a satellite navigation system expert from the academy.

The Spindle Galaxy: Messier 102 in Draco | Hubble Space Telescope

The Spindle Galaxy: Messier 102 in Draco | Hubble Space Telescope


Hubble’s sharp vision reveals a crisp dust lane dividing M102, also known as the Spindle galaxy, into two halves. This edge-on view of M102 highlights the galaxy’s structure: a subtle, reddish bulge surrounding a bright nucleus, a blue disk of stars running parallel to the dust lane, and a transparent outer halo.

M102’s dust lane is slightly warped compared to the disk of starlight. This warp indicates that the galaxy might have experienced gravitational tidal disturbances in the distant past. These disturbances were likely caused by an interaction with a nearby galaxy, as M102 is the largest member of a small cluster of galaxies.

Faint, wispy trails of dust can be seen meandering away from the disk out into the bulge and inner halo of the galaxy. The outer halo is dotted with numerous globular star clusters, gravitationally bound clusters of nearly a million stars each. Background galaxies that are millions to billions of light-years farther away than M102 are also seen through its halo.

Pierre Méchain, a French astronomer and colleague of Charles Messier, discovered the Spindle galaxy in 1781—the same year that he discovered the first two of his eight comets. M102 is located 44 million light-years from Earth in the constellation Draco and has an apparent magnitude of 10.7. It can be observed using a small telescope and is most easily spotted during July.

Chinese Scientists Discover New Mineral from Lunar Meteorite

Chinese Scientists Discover New Mineral from Lunar Meteorite

Chinese scientists have discovered and identified the 11th new lunar mineral, named Cerium-Magnesium Changesite, according to the China Geological Survey on April 22, 2026.

The newly discovered Cerium-Magnesium Changesite is colorless, transparent and brittle, exhibits a glassy luster, and shows a distinct fluorescence effect. The grain size ranges from approximately three to 25 micrometers, typically less than 10 micrometers, which is roughly one twenty-fifth of the diameter of a human hair.

"Why it is new is that when it was formed, it experienced two different conditions. The physical condition was temperature and pressure, while the chemical condition was its element content. The discovery of a new mineral in extraterrestrial space would indicate that conditions once existed beyond Earth that have never occurred on our planet. If the same mineral is later found on Earth, it would suggest our planet once experienced similar conditions, allowing us to use it to infer and compare broader geological and celestial activities," Che Xiaochao, associate researcher of the Institute of Geology of the Chinese Academy of Geological Sciences.

The Cerium-Magnesium Changesite was found in the first lunar meteorite falling in China. It is a single spherical meteorite with a weight of 44 grams and a dark molten shell on its surface.

An expert said that the discovery of new minerals from lunar meteorites can not only broaden people's understanding of the universe, but also provide new formulas for the field of synthetic materials.

"Cerium-Magnesium Changesite is found to have a fluorescent effect, which has promising potential applications in producing LEDs. Its rare earth element ratio, its magnesium and iron content, as well as the characteristic changes in its crystal structure, can provide important references for synthetic materials," said Qu Kai, a member of the Commission of New Minerals and Mineral Names of the Chinese Society of Mineralogy, Petrology and Geochemistry.

The Milky Way Glows over Vera Rubin Observatory in Chile | NOIRLab

The Milky Way Glows over Vera Rubin Observatory in Chile | NOIRLab


Two icons share the stage in this image: the luminous band of the Milky Way galaxy and NSF–DOE Vera C. Rubin Observatory. Rubin Observatory is jointly funded by the U.S. National Science Foundation (NSF) and the U.S. Department of Energy's Office of Science (DOE/SC). Rubin is a joint program of NSF NOIRLab and DOE’s SLAC National Accelerator Laboratory that cooperatively operate Rubin.

This year, Rubin Observatory will begin the Legacy Survey of Space and Time (LSST). For ten years, Rubin will repeatedly image the entire sky of the Southern Hemisphere, creating a time-lapse record of our Universe—the ultimate movie of the cosmos.

During the LSST, Rubin will measure about 17 billion stars in our galaxy, using six filters. Studying the positions, motions, and colors of stars and other objects in the Milky Way will help scientists better understand how our galaxy formed and evolved. By extension, scientists will then better understand how other galaxies have evolved throughout the Universe’s history. The word “galaxy” stems from the Greek root word gala or galakt, meaning “milk.” This references the milky, opaque appearance of the Milky Way, whose dusty bands are quite prominent in this photo.

This image also captures the red and green hues of airglow, a very faint optical phenomenon caused by light emitted by Earth’s atmosphere. While the colors appear quite prominent in this image, airglow has little effect on the ability of Rubin or other telescopes to observe the night sky.

Hernán Stockebrand, the photographer, is a NOIRLab Audiovisual Ambassador.
