Dive into NASA Research Through Citizen Science

NASA invites people of all ages and backgrounds to do NASA science as a part of real science projects that rely on volunteers. Citizen Science is a great way to make new friends, meet some scientists, and help NASA solve mysteries of the universe this summer – using just a phone or computer. You can join from anywhere, participate on your own schedule, and dive right into real research using actual mission data. Here are two examples:

  • Through Space Cloud Watch, you can help NASA study noctilucent clouds. Noctilucent means “night-shining,” and that’s exactly what they do! During summer twilight at high latitudes, these clouds catch sunlight and appear to glow even in a darkened sky. Take a photo and submit a report to help scientists track how these rare clouds are changing.
  • Take your cloud‑watching to another planet with Cloudspotting on Mars, where you review real NASA images to identify clouds above the Red Planet and help scientists understand Martian weather.

Curious about what other projects you might enjoy? See all current Citizen Science opportunities available through NASA’s Science Mission Directorate.

No matter how you spend your summer – building projects like the Hack Club’s Stardance Challenge, jumping into real NASA research through citizen science, or exploring possible NASA career paths – there’s a launch pad waiting for you. And remember, NASA’s STEM Resources website is available year-round to serve as your one-stop hub for hands-on activities, videos, articles, and more to spark curiosity and fuel big ideas.

Gravity Waves From Super Typhoon Sinlaku

2026-06-01 04:01

Gravity waves in the upper atmosphere appear as concentric rings in a nighttime, black and white satellite image. Clouds from a typhoon are also visible.
Atmospheric gravity waves generated by Super Typhoon Sinlaku are visible via mesospheric airglow in this nighttime image acquired with the VIIRS (Visible Infrared Imaging Radiometer Suite) on the NOAA-20 satellite on April 12, 2026, Universal Time (April 13 local time).

In mid-April 2026, Super Typhoon Sinlaku churned across the North Pacific Ocean and brought heavy rain and flooding to the Mariana Islands. The storm reached “violent typhoon” status—the highest intensity on the scale used by the Japan Meteorological Agency and roughly equivalent to a category 5 storm on the Saffir-Simpson wind scale. Sinlaku was one of only a handful of tropical cyclones of that intensity known to have occurred so early in the year in the region, meteorologists noted.

Sinlaku rapidly intensified over the ocean before its impacts reached land. Around the time of this strengthening, satellites began to detect that the typhoon’s effects also extended upward, into the upper atmosphere.

The nighttime image above, acquired with the VIIRS (Visible Infrared Imaging Radiometer Suite) on the NOAA-20 satellite, shows atmospheric gravity waves radiating from the typhoon. These waves, resembling ripples on a pond, were made visible to the sensor via airglow in the mesosphere. Airglow occurs when atoms and molecules, excited by sunlight during the day, later emit light to release excess energy.

The release of latent heat near the eyewalls of tropical cyclones is known to drive convection and the formation of tall cumulonimbus clouds. These “hot towers” can rise out of the troposphere, the lowest layer of the atmosphere, and generate waves that propagate into the stratosphere and mesosphere above. An analysis of past tropical cyclones revealed that gravity waves often occur around the time that storms are intensifying. Indeed, in the 24 hours prior to the acquisition of the image above, Sinlaku had strengthened from a category 2 to a category 5 storm.

“We’re seeing waves propagating radially and upward, in a cone-like shape,” said Joan Alexander, senior research scientist at NorthWest Research Associates. Alexander was surprised to see nearly complete rings in the mesospheric airglow above the storm. Winds in the upper atmosphere can dissipate the waves before they reach such high altitudes, Alexander explained, but relatively light stratospheric winds at the storm’s latitude in April 2026 may have helped preserve them.

A relatively low amount of moonlight was fortuitous, as well. The VIIRS day-night band is sensitive to airglow in the mesosphere but also observes reflected moonlight. The Moon was about 25 percent illuminated on April 12, so some light reflected off clouds in the troposphere was visible, but not enough to overpower the signal from the airglow.

The signature of gravity waves in the stratosphere appears as concentric rings in infrared satellite data.
Thermal energy from gravity waves produced by Super Typhoon Sinlaku was detected in the stratosphere by the AIRS (Atmospheric Infrared Sounder) instrument on NASA’s Aqua satellite on April 13, 2026.

Sinlaku’s gravity waves, in addition to appearing high in the atmosphere via airglow, were observed lower in the atmosphere by the AIRS (Atmospheric Infrared Sounder) instrument on NASA’s Aqua satellite. The image above depicts thermal emissions from gravity waves in the stratosphere on April 13. The rippling pattern appeared in April 14 observations, as well, indicating the storm’s continuing effects on the atmosphere.

Observing atmospheric gravity waves, particularly those caused by tropical cyclones, goes beyond scientific curiosity. Practical implications could include improved monitoring of storm development. “We’d like to use gravity waves to tell us if a storm is intensifying,” Alexander said, “which can be difficult to know, especially over the open ocean.” A geostationary satellite with the proper infrared imager would be able to observe gravity waves and track tropical cyclone evolution, she and colleagues have argued.

Furthermore, it’s critical to account for processes in the stratosphere in weather models, said Laura Holt, also a senior research scientist at NorthWest Research Associates. Stratospheric wind patterns are factors in long-term forecasts of the next Northern Hemisphere winter, for example, and tropical cyclones have a disproportionate influence because their sustained, intense convection drives prolonged gravity wave forcing of the stratosphere.

The effect of gravity waves even reaches into the realm of space weather. “For a while, people have seen signatures of hurricanes in ionospheric weather,” Holt said. Gravity waves can lead to traveling ionospheric disturbances—large-scale ripples in plasma density—and in some cases plasma bubbles, both of which can disrupt satellite signals and radio communications. “With space weather in particular,” Holt added, “a single event such as a tropical cyclone can be very important.”

NASA will host a public event featuring three crew members from the agency’s SpaceX Crew-11 mission at 11 a.m. EDT Monday, June 1. The event, which takes place during the crew’s standard postflight visit, will be held in the Webb Auditorium at NASA Headquarters in the Mary W. Jackson building, 300 E. Street SW in Washington.

The crew members, including NASA astronauts Zena Cardman and Mike Fincke and JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, will discuss their recent 167-day mission aboard the International Space Station, where they conducted a wide range of science experiments to benefit life on Earth and advance human space exploration as part of International Space Station Expedition 73/74.

The Crew-11 mission lifted off on Aug.1, 2025, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The crew’s SpaceX Dragon spacecraft docked to the orbital outpost on Aug. 2.

During their mission, the three astronauts, along with crewmate Roscosmos cosmonaut Oleg Platonov, traveled nearly 71 million miles and completed more than 2,670 orbits around Earth. The Crew-11 mission was Fincke’s fourth spaceflight, Yui’s second, and the first for Cardman and Platonov. Fincke has logged 549 days in space, ranking him fourth among all NASA astronauts for cumulative days in space. The crew members returned to Earth on Jan. 15, splashing down off the coast of San Diego.

Along the way, Crew-11 logged hundreds of hours of research, maintenance, and technology demonstrations. The crew members also celebrated the 25th anniversary of continuous human presence aboard the orbiting laboratory on Nov. 2, 2025. Research conducted aboard the space station advances scientific knowledge and demonstrates new technologies that enable us to prepare for human exploration of the Moon and Mars.

Media interested in attending the event must RSVP by 8 a.m., June 1, by emailing the NASA Headquarters newsroom at hq-media@mail.nasa.gov. NASA’s media accreditation policy is online. Based on the crew’s schedule, NASA will not be able to accommodate interviews.

This opportunity also is part of NASA’s Frontiers Forum: Voices Shaping the Future of Space speaking series designed to convene bold thinkers and senior leaders at the forefront of exploration and innovation. The series will spotlight mission-critical priorities from advancing the Artemis campaign and strengthening commercial partnerships to shaping the future workforce and accelerating breakthrough technologies. The agency will share more details soon.
