Hurricane Helene’s Gravity Waves Revealed by NASA’s AWE
On Sept. 26, 2024, Hurricane Helene slammed into the Gulf Coast of Florida, inducing storm surges and widespread impacts on communities in its path. At the same time, NASA’s Atmospheric Waves Experiment, or AWE, recorded enormous swells in the atmosphere that the hurricane produced roughly 55 miles above the ground. Such information helps us better understand how terrestrial weather can affect space weather, part of the research NASA does to understand how our space environment can disrupt satellites, communication signals, and other technology.

As the International Space Station traveled over the southeastern United States on Sept. 26, 2024, AWE observed atmospheric gravity waves generated by Hurricane Helene as the storm slammed into the gulf coast of Florida. The curved bands extending to the northwest of Florida, artificially colored red, yellow, and blue, show changes in brightness (or radiance) in a wavelength of infrared light produced by airglow in Earth’s mesosphere.

Utah State University These massive ripples through the upper atmosphere, known as atmospheric gravity waves, appear in AWE’s images as concentric bands (artificially colored here in red, yellow, and blue) extending away from northern Florida.
“Like rings of water spreading from a drop in a pond, circular waves from Helene are seen billowing westward from Florida’s northwest coast,” said Ludger Scherliess, who is the AWE principal investigator at Utah State University in Logan.
Launched in November 2023 and mounted on the outside of the International Space Station, the AWE instrument looks down at Earth, scanning for atmospheric gravity waves, ripple-like patterns in the air generated by atmospheric disturbances such as violent thunderstorms, tornadoes, tsunamis, wind bursts over mountain ranges, and hurricanes. It does this by looking for brightness fluctuations in colorful bands of light called airglow in Earth’s mesosphere. AWE’s study of these gravity waves created by terrestrial weather helps NASA pinpoint how they affect space weather.
These views of gravity waves from Hurricane Helene are among the first publicly released images from AWE, confirming that the instrument has the sensitivity to reveal the impacts hurricanes have on Earth’s upper atmosphere.

Para celebrar el Mes de la Herencia Hispana, la NASA publica nuevos contenidos para Universo curioso de la NASA, el primer pódcast en español de la agencia, que inicia ahora su segunda temporada. La temporada de cinco semanas comienza el martes, con nuevos episodios disponibles semanalmente.
Escucha el avance de la segunda temporada de Universo curioso de la NASA.
En cada episodio, Universo curioso destaca las contribuciones de la fuerza laboral hispana y latina de la NASA al trabajo de la agencia en el ámbito de la exploración de la Tierra y el espacio en beneficio de todos.
“Mediante el pódcast Universo curioso de la NASA, estamos entusiasmados de contar la historia de los esfuerzos de la NASA para que el espacio esté al alcance de más gente de todo el mundo”, dijo Tonya McNair, administradora asociada adjunta de la Dirección de Misiones de Operaciones Espaciales de la NASA en Washington. “En la segunda temporada, escucharán a trabajadores hispanos y latinos de la NASA, como la directora de vuelo Diana Trujillo y el astronauta Marcos Berríos, que ayudan a dirigir algunas de las misiones de exploración espacial más vitales de la agencia e inspiran al mundo a través del descubrimiento.”
Los episodios se centran en algunas de las principales misiones de la NASA, acercando las maravillas de la exploración, la tecnología espacial y los descubrimientos científicos al público hispanohablante del mundo entero.
“Este pódcast pone en relieve la dedicación de la NASA a hacer que el conocimiento esté a disposición de todos, independientemente de su lengua materna”, dijo Shahra Lambert, asesora principal de la NASA para la participación pública. “Al compartir la emoción de las misiones de la NASA en el segundo idioma más hablado en los EE.UU. y en todo el mundo, estamos amplificando nuestro alcance y posiblemente allanando el camino para una fuerza de trabajo en ciencia, tecnología, ingeniería y matemáticas más diversa en el futuro.”
El primer episodio de Universo curioso se emitió en 2021, como parte de la cobertura en español del lanzamiento del telescopio espacial James Webb. En 2023, el programa fue seleccionado como “Programa que nos encanta” por Apple Podcasts Latinoamérica.
Presentado por Noelia González, especialista en comunicaciones del Centro Goddard de Vuelo Espacial de la NASA en Greenbelt, Maryland, en el pódcast invitamos a los oyentes a emprender un viaje a una de las lunas heladas de Júpiter, a oír acerca de los dos primeros años de descubrimientos del telescopio espacial James Webb, así como a conocer la trayectoria de un astronauta de Puerto Rico y de una directora de vuelo colombiana para llegar a la NASA.
Los episodios cubrirán el próximo lanzamiento de Europa Clipper en octubre de 2024, una misión que tiene como objetivo determinar si existen lugares bajo la superficie de la luna helada de Júpiter, Europa, que puedan albergar vida.
A continuación figura la lista completa de los nuevos episodios, así como sus fechas de publicación:
Martes, 17 de septiembre: Avance de la segunda temporada Martes, 24 de septiembre: Diana Trujillo: De Cali a la Luna y Marte Martes, 1 de octubre: Europa Clipper: Un viaje poético a la luna de Júpiter Martes, 8 de octubre: Marcos Berríos: Cómo convertirse en astronauta de la NASA Martes, 15 de octubre: Explorando el cosmos con Webb Universo curioso de la NASA es una iniciativa conjunta de los programas de comunicación en español y de audio de la agencia. La nueva temporada, así como los episodios anteriores, están disponibles en Apple Podcasts, Spotify y el sitio web de la NASA.

In celebration of Hispanic Heritage Month, NASA is releasing new content for Universo curioso de la NASA, the agency’s first Spanish-language podcast, now in its second season. A five-week season starts Tuesday with new episodes released weekly.
Listen to the preview of the second season of Universo curioso de la NASA.
In each episode, Universo curioso highlights the contributions of NASA’s Hispanic and Latino workforce to the agency’s work in Earth and space exploration for the benefit of all.
“Through the Universo curioso de la NASA podcast, we are thrilled to tell the story of NASA’s efforts to open space to more people from across the world,” said Tonya McNair, deputy associate administrator for NASA’s Space Operations Mission Directorate in Washington. “In the second season, you’ll hear from NASA’s Hispanic and Latino workforce, like flight director Diana Trujillo and astronaut Marcos Berríos, helping lead some of the agency’s most vital space exploration missions and inspiring the world through discovery.”
Episodes focus on some of NASA’s top missions, bringing the wonder of exploration, space technology, and scientific discoveries to Spanish-speaking audiences around the world.
“This podcast highlights NASA’s dedication to making knowledge available to all, regardless of their native language,” said Shahra Lambert, NASA senior advisor for engagement. “By sharing the excitement of NASA’s missions in the second most spoken language in the U.S. and around the world, we are amplifying our outreach and possibly paving the way for a more diverse STEM workforce in the future.”
The first episode of Universo curioso ran in 2021, as part of the agency’s Spanish coverage of the launch of its James Webb Space Telescope. In 2023, the show was selected as a “Podcast We Love” by Apple Podcasts Latin America.
Hosted by Noelia González, communications specialist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, listeners are invited to go on a journey to one of Jupiter’s icy moons, hear about the first two years of discoveries of the James Webb Space Telescope, as well as learn about an astronaut from Puerto Rico’s and a Colombian flight director’s path to NASA.
Episodes will cover the upcoming launch of Europa Clipper in October 2024, a mission that aims to determine whether there are places below the surface of Jupiter’s icy moon, Europa, that could support life.
A complete list of the new episodes, as well as their release dates, is as follows:
Tuesday, Sept. 17: Introducing the Second Season Tuesday, Sept. 24 Diana Trujillo: From Cali to the Moon and Mars Tuesday, Oct. 1 Europa Clipper: A Poetic Journey to Jupiter’s Moon Tuesday, Oct. 8 Marcos Berríos: How to Become a NASA Astronaut Tuesday, Oct. 15: Exploring Cosmos with Webb Universo curioso de la NASA is a joint initiative of the agency’s Spanish-language communications and audio programs. The new season, as well as previous episodes, are available on Apple Podcasts, Spotify, and NASA’s website.
