5 Min Read Planetary Alignment Provides NASA Rare Opportunity to Study Uranus
Artist's illustration showing a distant star going out of sight as it is eclipsed by Uranus – an event known as a planetary stellar occultation. Credits: NASA/Advanced Concepts Laboratory When a planet’s orbit brings it between Earth and a distant star, it’s more than just a cosmic game of hide and seek. It’s an opportunity for NASA to improve its understanding of that planet’s atmosphere and rings. Planetary scientists call it a stellar occultation and that’s exactly what happened with Uranus on April 7.
Observing the alignment allows NASA scientists to measure the temperatures and composition of Uranus’ stratosphere – the middle layer of a planet’s atmosphere – and determine how it has changed over the last 30 years since Uranus’ last significant occultation.

This rendering demonstrates what is happening during a stellar occultation and illustrates an example of the light curve data graph recorded by scientists that enables them to gather atmospheric measurements, like temperature and pressure, from Uranus as the amount of starlight changes when the planet eclipses the star.NASA/Advanced Concepts Laboratory “Uranus passed in front of a star that is about 400 light years from Earth,” said William Saunders, planetary scientist at NASA’s Langley Research Center in Hampton, Virginia, and science principal investigator and analysis lead, for what NASA’s team calls the Uranus Stellar Occultation Campaign 2025. “As Uranus began to occult the star, the planet’s atmosphere refracted the starlight, causing the star to appear to gradually dim before being blocked completely. The reverse happened at the end of the occultation, making what we call a light curve. By observing the occultation from many large telescopes, we are able to measure the light curve and determine Uranus’ atmospheric properties at many altitude layers.”

This data mainly consists of temperature, density, and pressure of the stratosphere. Analyzing the data will help researchers understand how the middle atmosphere of Uranus works and could help enable future Uranus exploration efforts.
To observe the rare event, which lasted about an hour and was only visible from Western North America, planetary scientists at NASA Langley led an international team of over 30 astronomers using 18 professional observatories.
Kunio Sayanagi, NASA’s principal investigator for the Uranus Stellar Occultation Campaign 2025, meeting virtually with partners and observing data from the Flight Mission Support Center at NASA’s Langley Research Center in Hampton, Virginia during Uranus’ stellar occultation event on April 7, 2025.NASA/Dave MacDonnell “This was the first time we have collaborated on this scale for an occultation,” said Saunders. “I am extremely grateful to each member of the team and each observatory for taking part in this extraordinary event. NASA will use the observations of Uranus to determine how energy moves around the atmosphere and what causes the upper layers to be inexplicably hot. Others will use the data to measure Uranus’ rings, its atmospheric turbulence, and its precise orbit around the Sun.”
Knowing the location and orbit of Uranus is not as simple as it sounds. In 1986, NASA’s Voyager 2 spacecraft became the first and only spacecraft to fly past the planet – 10 years before the last bright stellar occultation occured in 1996. And, Uranus’ exact position in space is only accurate to within about 100 miles, which makes analyzing this new atmospheric data crucial to future NASA exploration of the ice giant.
These investigations were possible because the large number of partners provided many unique views of the stellar occultation from many different instruments.
NASA planetary scientist William Saunders and Texas A&M University research assistant Erika Cook in the control room of the McDonald Observatory’s Otto Struve Telescope in Jeff Davis County, Texas, during the Uranus stellar occultation on April 7, 2025.Joshua Santana Emma Dahl, a postdoctoral scholar at Caltech in Pasadena, California, assisted in gathering observations from NASA’s Infrared Telescope Facility (IRTF) on the summit of Mauna Kea in Hawaii – an observatory first built to support NASA’s Voyager missions.
“As scientists, we do our best work when we collaborate. This was a team effort between NASA scientists, academic researchers, and amateur astronomers,” said Dahl. “The atmospheres of the gas and ice giant planets [Jupiter, Saturn, Uranus, and Neptune] are exceptional atmospheric laboratories because they don’t have solid surfaces. This allows us to study cloud formation, storms, and wind patterns without the extra variables and effects a surface produces, which can complicate simulations very quickly.”
On November 12, 2024, NASA Langley researchers and collaborators were able to do a test run to prepare for the April occultation. Langley coordinated two telescopes in Japan and one in Thailand to observe a dimmer Uranus stellar occultation only visible from Asia. As a result, these observers learned how to calibrate their instruments to observe stellar occultations, and NASA was able to test its theory that multiple observatories working together could capture Uranus’ big event in April.
Researchers from the Paris Observatory and Space Science Institute, in contact with NASA, also coordinated observations of the November 2024 occultation from two telescopes in India. These observations of Uranus and its rings allowed the researchers, who were also members of the April 7 occultation team, to improve the predictions about the timing on April 7 down to the second and also improved modeling to update Uranus’ expected location during the occultation by 125 miles.
This image of Uranus from NIRCam (Near-Infrared Camera) on NASA’s James Webb Space Telescope exquisitely captures Uranus’s seasonal north polar cap and dim inner and outer rings. This Webb image also shows 9 of the planet’s 27 moons – clockwise starting at 2 o’clock, they are: Rosalind, Puck, Belinda, Desdemona, Cressida, Bianca, Portia, Juliet, and Perdita.NASA, ESA, CSA, STScI Uranus is almost 2 billion miles away from Earth and has an atmosphere composed of primarily hydrogen and helium. It does not have a solid surface, but rather a soft surface made of water, ammonia, and methane. It’s called an ice giant because its interior contains an abundance of these swirling fluids that have relatively low freezing points. And, while Saturn is the most well-known planet for having rings, Uranus has 13 known rings composed of ice and dust.
Over the next six years, Uranus will occult several dimmer stars. NASA hopes to gather airborne and possibly space-based measurements of the next bright Uranus occultation in 2031, which will be of an even brighter star than the one observed in April.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Researchers use a flat aerogel array antenna to communicate with a geostationary satellite above the Earth during tests at NASA’s Glenn Research Center in Cleveland.Credit: NASA/Jordan Cochran NASA engineers are using one of the world’s lightest solid materials to construct an antenna that could be embedded into the skin of an aircraft, creating a more aerodynamic and reliable communication solution for drones and other future air transportation options.
Developed by NASA, this ultra-lightweight aerogel antenna is designed to enable satellite communications where power and space are limited. The aerogel is made up of flexible, high-performance plastics known as polymers. The design features high air content (95%) and offers a combination of light weight and strength. Researchers can adjust its properties to achieve either the flexibility of plastic wrap or the rigidity of plexiglass.
“By removing the liquid portion of a gel, you’re left with this incredibly porous structure,” said Stephanie Vivod, a chemical engineer at NASA’s Glenn Research Center in Cleveland. “If you’ve ever made Jell-O, you’ve performed chemistry that’s similar to the first step of making an aerogel.”
NASA sandwiched a layer of aerogel between a small circuit board and an array of thin, circular copper cells, then topped the design off with a type of film known for its electrical insulation properties. This innovation is known at NASA and in the aviation community as an active phased array aerogel antenna.

They are also less visually intrusive compared to other types of antennas, such as spikes and blades. The finished product looks like a honeycomb but lays flat on an aircraft’s surface.
In the summer of 2024, researchers tested a rigid version of the antenna on a Britten-Norman Defender aircraft during an in-flight demonstration with the U.S. Navy at Naval Air Station Patuxent River in Maryland.

The aircraft was used to verify data transmission quality and communications link resiliency with a low Earth orbit satellite.Credit: U.S. Navy Then, last October, researchers at NASA Glenn and the satellite communications firm Eutelsat America Corp., of Houston, began ground testing a version of the antenna mounted to a platform. The team successfully connected with a Eutelsat satellite in geostationary orbit, which bounced a signal back down to a satellite dish on a building at Glenn. Other demonstrations of the system at Glenn connected with a constellation of communications satellites operated in low Earth orbit by the data relay company Kepler. NASA researchers will design, build, and test a flexible version of the antenna later this year.
“This is significant because we are able to use the same antenna to connect with two very different satellite systems,” said Glenn researcher Bryan Schoenholz. Low Earth orbit satellites are relatively close – at 1,200 miles from the surface – and move quickly around the planet. Geostationary satellites are much farther – more than 22,000 miles from the surface – but orbit at speeds matching the Earth’s rotation, so they appear to remain in a fixed position above the equator.

They used a flat version of an aerogel antenna during tests in October 2024.Credit: NASA/Jordan Cochran The satellite testing was crucial for analyzing the aerogel antenna concept’s potential real-world applications. When modern aircraft communicate with stations on the ground, those signals are often transmitted through satellite relays, which can come with delays and loss of communication. This NASA-developed technology will make sure these satellite links are not disrupted during flight as the aerogel antenna’s beam is a concentrated flow of radio waves that can be electronically steered with precision to maintain the connection.
As new types of air transportation options are brought to the market and U.S airspace – from the small, piloted aircraft of today to the autonomous air taxis and delivery drones of tomorrow – these kinds of steady connections will become increasingly important. That’s why NASA’s Advanced Air Mobility mission and Transformative Aeronautics Concepts program are supporting research like the aerogel antennas that can boost industry efforts to safely expand the emerging marketplace for these transportation systems.
“If an autonomous air taxi or drone flight loses its communications link, we have a very unsafe situation,” Schoenholz said. “We can’t afford a ‘dropped call’ up there because that connection is critical to the safety of the flight.”
Schoenholz, Vivod, and others work on NASA’s Antenna Deployment and Optimization Technologies activity within the Transformational Tools and Technologies project. The activity aims to develop technologies that reduce the risk of radio frequency interference from air taxis, drones, commercial passenger jets, and other aircraft in increasingly crowded airspace.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Earth Day Poster for 2025 uses imagery from the Landsat mission — a joint mission with USGS — to celebrate our home planet. NASA/USGS/Landsat From the iconic image of Earthrise taken by Apollo 8 crew, to the famous Pale Blue Dot image of Earth snapped by Voyager I spacecraft, to state-of-the-art observations of our planet by new satellites such as PACE (Plankton, Aerosol, Cloud, ocean Ecosystem), NASA has given us novel ways to see our home. This Earth Day, NASA is sharing how — by building on decades of innovation—we use the unique vantage point of space to observe and understand our dynamic planet in ways that we cannot from the ground.
NASA has been observing Earth from space for more than 60 years, with cutting-edge scientific technology that can revolutionize our understanding of our home planet and provide benefits to all humanity. NASA observations include land data that helps farmers improve crop production, research on the air we breathe, and studies of atmospheric layers high above us that protect every living thing on the planet.
“NASA Science delivers every second of every day for the benefit all, and it begins with how we observe our home planet from the unique vantage point of space,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “Our satellites, Mars rovers, astronauts and other NASA Science missions send back beautiful images of our planet, from the smallest of plankton to the pale blue dot, to help give us a comprehensive, detailed view of our home that we especially celebrate each Earth Day.”
NASA data and tools are vital to federal, state, local, and international governments to monitor and manage land, air, and water resources. From mapping the ocean floor to finding critical mineral deposits to alerting land managers when fire risk is high, NASA’s data and information informs nearly every aspect of our economy and our lives.
“Another way NASA celebrates Earth Day is by sharing information about how our science benefits the entire nation, such as by providing U.S. farmers and ranchers with ongoing measurements of water, crop health, wildfire predictions, and knowledge of what is being grown around the world,” said Karen St. Germain, director of NASA’s Earth Science Division at the agency’s headquarters in Washington. “This data informs field level farming and ranching decisions with impact felt as far as the commodity-trading floor and our grocery stores.”
Next up for NASA’s work to help mitigate natural disasters is a mission called NISAR (NASA-ISRO Synthetic Aperture Radar) which is a partnership between NASA and ISRO (India Space Research Organization). NISAR, which is targeted to launch later this year, will measure land changes from earthquakes, landslides, and volcanos, producing more NASA science data to aid in disaster response. The mission’s radar will detect movements of the planet’s surface as small as 0.4 inches over areas about the size of half a tennis court. By tracking subtle changes in Earth’s surface, it will spot warning signs of imminent volcanic eruptions, help to monitor groundwater supplies, track the melt rate of ice sheets tied to sea level rise, and observe shifts in the distribution of vegetation around the world.
From our oceans to our skies, to our ice caps, to our mountains, and to our rivers and streams, NASA’s Earth observations enhance our understanding of the world around us and celebrate the incredible planet we call home.
