An international team of astronomers using the NASA/ESA Hubble Space Telescope has made new measurements of Uranus’ interior rotation rate with a novel technique, achieving a level of accuracy 1,000 times greater than previous estimates. By analyzing more than a decade of Hubble observations of Uranus’ aurorae, researchers have refined the planet’s rotation period and established a crucial new reference point for future planetary research.
These images from the NASA/ESA Hubble Space Telescope showcase the dynamic aurora on Uranus in October 2022. These observations were made by the Space Telescope Imaging Spectrograph (STIS) and includes both visible and ultraviolet data. An international team of astronomers used Hubble to make new measurements of Uranus’ interior rotation rate by analyzing more than a decade of the telescope’s observations of Uranus’ aurorae. This refinement of the planet’s rotation period achieved a level of accuracy 1000 times greater than previous estimates and serves as a crucial new reference point for future planetary research. ESA/Hubble, NASA, L. Lamy, L. SromovskyDetermining a planet’s interior rotation rate is challenging, particularly for a world like Uranus, where direct measurements are not possible. A team led by Laurent Lamy (of LIRA, Observatoire de Paris-PSL and LAM, Aix-Marseille Univ., France), developed an innovative method to track the rotational motion of Uranus’ aurorae: spectacular light displays generated in the upper atmosphere by the influx of energetic particles near the planet’s magnetic poles. This technique revealed that Uranus completes a full rotation in 17 hours, 14 minutes, and 52 seconds — 28 seconds longer than the estimate obtained by NASA’s Voyager 2 during its 1986 flyby.
“Our measurement not only provides an essential reference for the planetary science community but also resolves a long-standing issue: previous coordinate systems based on outdated rotation periods quickly became inaccurate, making it impossible to track Uranus’ magnetic poles over time,” explains Lamy. “With this new longitude system, we can now compare auroral observations spanning nearly 40 years and even plan for the upcoming Uranus mission.”

ESA/Hubble, NASA, L. Lamy, L. SromovskyThis breakthrough was possible thanks to Hubble’s long-term monitoring of Uranus. Over more than a decade, Hubble has regularly observed its ultraviolet auroral emissions, enabling researchers to produce magnetic field models that successfully match the changing position of the magnetic poles with time.
“The continuous observations from Hubble were crucial,” says Lamy. “Without this wealth of data, it would have been impossible to detect the periodic signal with the level of accuracy we achieved.”
Unlike the aurorae of Earth, Jupiter, or Saturn, Uranus’ aurorae behave in a unique and unpredictable manner. This is due to the planet’s highly tilted magnetic field, which is significantly offset from its rotational axis. The findings not only help astronomers understand Uranus’ magnetosphere but also provide vital information for future missions.
These findings set the stage for further studies that will deepen our understanding of one of the most mysterious planets in the Solar System. With its ability to monitor celestial bodies over decades, the Hubble Space Telescope continues to be an indispensable tool for planetary science, paving the way for the next era of exploration at Uranus.
These results are based on observations acquired with Hubble programs GO #12601, 13012, 14036, 16313 and DDT #15380 (PI: L. Lamy). The team’s paper was published in Nature Astronomy.
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

Flocks of CubeSats Can Efficiently Monitor Farms
The widespread use of low Earth orbit (LEO), especially by thousands of CubeSats, has opened up many opportunities in research and business applications. One particular field that has benefited from the data that CubeSats provide is farming. Precision agriculture (PA) is a technique that uses advanced sensors, including the remote ones on CubeSats, to determine the health and productivity of a farm. A recent review paper from Lamia Rahali and her co-authors at the Mediterranea University of Reggio Calabria's Department of Agriculture looks at how CubeSats have been changing the practice of precision agriculture - and how they may continue to do so.

Expedition 73 Crew Launches to International Space Station
A Soyuz rocket launches to the International Space Station with Expedition 73 crew members including NASA astronaut Jonny Kim on Tuesday, April 8, 2025, at the Baikonur Cosmodrome in Kazakhstan.
The crew arrived at the space station the same day, bringing the number of residents to 10 for the next two weeks. Expedition 73 will begin on Saturday, April 19, following the departure of NASA astronaut Don Pettit and Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner, as they conclude a seven-month science mission aboard the orbiting laboratory.
Throughout his eight-month stay aboard the orbital outpost, Kim will conduct scientific research in technology development, Earth science, biology, and human research.

NASA Science Supports Data Literacy for K-12 Students
3 min read
NASA Science Supports Data Literacy for K-12 StudentsData – and our ability to understand and use it – shapes nearly every aspect of our world, from decisions in our lives to the skills we need in the workplace and more. All of us, as either producers or consumers of data, will experience how it can be used to problem-solve and think critically as we navigate the world around us. For that reason, Data Science has become an increasingly essential and growing field that combines the collection, organization, analysis, interpretation, and sharing of data in virtually every area of life. As more data become more openly available, our Data Science skills will be of increasing importance. And yet, there is a widening gap between what students learn in school and the skills they will need to succeed in a data-driven world. The integration of Data Science into K-12 education opens doors to higher education, high-paying careers, and empowering learners to eventually participate in the creation of new knowledge and understanding of our world, and at least 29 states have reported some level of data science implementation at the K-12 level, including standard or framework adoption, course piloting, and educator professional learning.
In February 2025, the first-ever Data Science Education K-12: Research to Practice Conference (DS4E) took place in San Antonio, TX. A number of representatives from NASA’s Science Activation program and other NASA partners attended and presented along with over 250 educators, researchers, and school leaders from across the nation. Science Activation projects share a passion for helping people of all ages and backgrounds connect with NASA science experts, content, experiences, and learning resources, and the AEROKATS & ROVER Education Network (AREN); Place-Based Learning to Advance Connections, Education, and Stewardship (PLACES); Global Learning and Observations to Benefit the Environment (GLOBE) Mission Earth; and My NASA Data teams did just that. Their presentations at the conference included:
- “BYOD – Build or Bring Your Own Data: Developing K-12 Datasets” (PLACES)
- “Using NASA Data Resources as a Tool to Support Storytelling with Data in K-12 Education” (My NASA Data)
- “Place-Based Data Literacy: Real People, Real Places, Real Data” (AREN)
Conference participants expressed interest in learning more about NASA assets, including data and subject matter experts. Stemming from their participation in this first DS4E, several Science Activation teams are collaborating to potentially host regional events next year under the umbrella of this effort (PLACES in particular), a wonderful example of how Science Activation project teams help lead the charge in the advancement of key Science, Technology, Education, and Mathematics (STEM) fields, such as Data Science, to activate minds and promote a deeper understanding of our world and beyond.
