NASA/JPL-Caltech/MSSS The United States flag adorns an aluminum plate mounted at the base of the mast, or “head,” of NASA’s Perseverance Mars rover. This image of the plate was taken on June 28, 2025 (the 1,548th day, or sol, of the mission), by the WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera on the end of the rover’s robotic arm.
WATSON, part of an instrument called SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals), was built by Malin Space Science Systems (MSSS) in San Diego and is operated jointly by MSSS and NASA’s Jet Propulsion Laboratory in Southern California. JPL, which is managed for the agency by Caltech, built and manages operations of the Perseverance rover.

Artist’s concept of the star HIP 67522 with a flare erupting toward an orbiting planet, HIP 67522 b. A second planet, HIP 67522 c, is shown in the background. Janine Fohlmeister, Leibniz Institute for Astrophysics Potsdam The Discovery
A giant planet some 400 light-years away, HIP 67522 b, orbits its parent star so tightly that it appears to cause frequent flares from the star’s surface, heating and inflating the planet’s atmosphere.
Key Facts
On planet Earth, “space weather” caused by solar flares might disrupt radio communications, or even damage satellites. But Earth’s atmosphere protects us from truly harmful effects, and we orbit the Sun at a respectable distance, out of reach of the flares themselves.
Not so for planet HIP 67522 b. A gas giant in a young star system – just 17 million years old – the planet takes only seven days to complete one orbit around its star. A “year,” in other words, lasts barely as long as a week on Earth. That places the planet perilously close to the star. Worse, the star is of a type known to flare – especially in their youth.
In this case, the proximity of the planet appears to result in fairly frequent flaring.
Details
The star and the planet form a powerful but likely a destructive bond. In a manner not yet fully understood, the planet hooks into the star’s magnetic field, triggering flares on the star’s surface; the flares whiplash energy back to the planet. Combined with other high-energy radiation from the star, the flare-induced heating appears to have increased the already steep inflation of the planet’s atmosphere, giving HIP 67522 b a diameter comparable to our own planet Jupiter despite having just 5% of Jupiter’s mass.
This might well mean that the planet won’t stay in the Jupiter size-range for long. One effect of being continually pummeled with intense radiation could be a loss of atmosphere over time. In another 100 million years, that could shrink the planet to the status of a “hot Neptune,” or, with a more radical loss of atmosphere, even a “sub-Neptune,” a planet type smaller than Neptune that is common in our galaxy but lacking in our solar system.
Fun Facts
Four hundred light-years is much too far away to capture images of stellar flares striking orbiting planets. So how did a science team led by Netherlands astronomer Ekaterina Ilin discover this was happening? They used space-borne telescopes, NASA’s TESS (Transiting Exoplanet Survey Satellite) and the European Space Agency’s CHEOPS (CHaracterising ExoPlanets Telescope), to track flares on the star, and also to trace the path of the planet’s orbit.
Both telescopes use the “transit” method to determine the diameter of a planet and the time it takes to orbit its star. The transit is a kind of mini-eclipse. As the planet crosses the star’s face, it causes a tiny dip in starlight reaching the telescope. But the same observation method also picks up sudden stabs of brightness from the star – the stellar flares. Combining these observations over five years’ time and applying rigorous statistical analysis, the science team revealed that the planet is zapped with six times more flares than it would be without that magnetic connection.
The Discoverers
A team of scientists from the Netherlands, Germany, Sweden, and Switzerland, led by Ekaterina Ilin of the Netherlands Institute for Radio Astronomy, published their paper on the planet-star connection, “Close-in planet induces flares on its host star,” in the journal Nature on July 2, 2025.

La NASA estrenó el martes el primer episodio de la tercera temporada de Universo curioso de la NASA, el único pódcast en español de la agencia.
Los episodios se centran en algunas de las principales misiones y temas de investigación de la NASA para 2025, llevando la maravilla de la exploración, la tecnología espacial y los descubrimientos científicos al público de habla hispana de todo el mundo.
“La ciencia de la NASA está literalmente en todas partes, y trasciende la geografía y los idiomas para ofrecer beneficios, en tiempo real, en la vida cotidiana de las personas de todo el mundo que utilizan nuestras innovaciones, datos y descubrimientos científicos alcanzados desde el punto de vista único del espacio”, dijo la doctora Nicky Fox, administradora asociada de la Dirección de Misiones Científicas, en la sede central de la NASA en Washington. “El pódcast Universo curioso de la NASA comparte los descubrimientos de la NASA con las comunidades de habla hispana de todo el mundo, inspirando a futuros exploradores a unirse a nuestro viaje mientras regresamos a la Luna y nos aventuramos hacia Marte en beneficio de toda la humanidad”.
Todos los meses se presentarán nuevos episodios hasta el final del año. El primer episodio, centrado en los objetivos científicos de la misión a la Luna Artemis II de la NASA, está disponible en:
https://go.nasa.gov/4l9lmbN
Universo curioso es presentado por Noelia González, especialista en comunicaciones en el Centro de Vuelo Espacial Goddard de la NASA en Greenbelt, Maryland. Esta temporada tendrá al coanfitrión Andrés Almeida, escritor técnico y anfitrión del pódcast de la NASA Small Steps, Giant Leaps (Pasos pequeños, grandes saltos) en la sede central de la NASA. A lo largo de la temporada, los oyentes celebrarán el legado del telescopio espacial Hubble de la NASA, aprenderán sobre una próxima misión al Sol y explorarán la energía oscura y cómo la estudiará el futuro telescopio espacial Roman, entre otros temas.
Universo curioso de la NASA es una iniciativa conjunta de los programas de comunicaciones en español y audio de la agencia. La nueva temporada, así como los episodios anteriores, están disponibles en Apple Podcasts, Spotify, SoundCloud y el sitio web de la NASA.

NASA released the first episode Tuesday of its third season of Universo curioso de la NASA, the agency’s only Spanish-language podcast.
Episodes focus on some of NASA’s top missions and research topics for 2025, bringing the wonder of exploration, space technology, and scientific discoveries to Spanish-speaking audiences around the world.
“NASA Science is literally everywhere, transcending geography and language to provide real time benefits to everyday lives across the globe using our scientific innovations, data, and discoveries from the unique vantage point of space,” said Dr. Nicky Fox, associate administrator, Science Mission Directorate, at NASA Headquarters in Washington. “The Universo curioso de la NASA podcast shares NASA’s discoveries with Spanish-speaking communities across the globe, inspiring future explorers to join our journey as we return to the Moon and venture onward to Mars for the benefit of all humanity.”
New episodes will post every month through the end of the year. The first episode, centered on the science objectives of NASA’s Artemis II mission to the Moon, is available at:
https://go.nasa.gov/4l9lmbN
Universo curioso is hosted by Noelia González, communications specialist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. This season introduces co-host Andrés Almeida, technical writer and host of NASA’s Small Steps, Giant Leaps podcast at NASA’s Headquarters. Throughout the season, listeners will celebrate the legacy of NASA’s Hubble Space Telescope, learn about an upcoming mission to the Sun, and explore dark energy and how the future Roman Space Telescope will study it, among other topics.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured compelling evidence of a planet with a mass similar to Saturn orbiting the young nearby star TWA 7.
If confirmed, this would represent Webb’s first direct image discovery of a planet, and the lightest planet ever seen with this technique.
