An international team of scientists, led by Madyson Barber of the University of North Carolina at Chapel Hill and with the participation of the Institute of Astrophysics of the Canary Islands (IAC)has discovered an exoplanet that marks a before and after in the study of planetary formation. This young giant, called IRAS 04125+2902 b, was found using the transit technique and is the youngest planet ever detected using this method.
Despite its youth, this planet already has impressive dimensions: Its radius is 10.7 times greater than that of the Earthand its mass is 30% that of Jupiter. However, this “little planet” is predicted to contract and evolve into a type known as a super-Earth or sub-Neptune.
The discovery represents a milestone, as until now the planets detected using the transit method were more than 10 million years old. This discovery opens a unique window to study how younger planets form and evolve.
A unique cosmic environment
The parent star of this exoplanet still retains part of its protoplanetary disk, the ring of gas and dust from which planets and stars are born. The researchers noticed that the outer disk is misaligned, while the inner one appears to have been “cleaned”. This exceptional configuration allowed the planet to be detected as it passed in front of its star, causing periodic dips in brightness.
The role of the TESS satellite
The discovery was made possible thanks to data collected by NASA’s Transiting Exoplanet Survey Satellite (TESS). designed to search for exoplanets using the transit method. The observations were confirmed with telescopes in the Las Cumbres Observatory network, including those at the Teide Observatory, in Tenerife.
Implications of the discovery
The researchers highlight the relevance of this discovery for understand the first chapters of the life of a planet. Felipe Murgas, one of the authors of the research published in the prestigious journal Nature, explains: “This discovery confirms that planets form rapidly, in a few million years. Furthermore, their clear transit demonstrates that they already have a defined spherical shape, challenging previous models of planetary formation.”
It is only 3 million years old, This planet and its star system are a key element in refining theoretical models of planet formation. Furthermore, being relatively close to Earth, its study promises to reveal clues about how worlds arise in our universe. IRAS 04125+2902 b is, without a doubt, a ‘child’ who does not just carry bread under his arm for science.

– What is the significance of the discovery of the exoplanet IRAS 04125+2902 b in terms of planetary formation?
Time.news Editor: Welcome, Dr. Madyson Barber! Thank you for joining us today. Congratulations on your groundbreaking discovery of the exoplanet IRAS 04125+2902 b. This finding seems to revolutionize our understanding of planetary formation. Can you begin by sharing how this discovery came about?
Dr. Madyson Barber: Thank you for having me! It’s a pleasure to discuss our research. The discovery of IRAS 04125+2902 b was made possible by an international collaboration, including teams from the University of North Carolina at Chapel Hill and the Institute of Astrophysics of the Canary Islands. We used the transit technique, which allows us to detect exoplanets as they pass in front of their parent star, creating a temporary dimming effect. What makes this particularly exciting is that this planet is the youngest ever detected using this method.
Time.news Editor: That’s fascinating! Can you elaborate on what makes IRAS 04125+2902 b so unique in comparison to previously detected exoplanets?
Dr. Madyson Barber: Absolutely. The key distinction lies in its age and its size. Until now, the planets detected via the transit method were typically over 10 million years old. IRAS 04125+2902 b, however, is in its infancy, allowing us to study planetary formation in a much earlier stage than was previously possible. Moreover, its impressive proportions—it has a radius 10.7 times that of Earth and a mass about 30% that of Jupiter—pave the way for predicting its future evolution into a super-Earth or sub-Neptune.
Time.news Editor: Intriguing! And what implications does the discovery of such a young planet have for our broader understanding of planet formation and evolution?
Dr. Madyson Barber: This discovery opens a unique window into planetary science. Since we have the opportunity to observe a young giant that still retains part of its protoplanetary disk, we can investigate how planets form and evolve during their formative years. The fact that the outer disk is misaligned while the inner one seems “cleaned” provides insights into the dynamics of disk evolution and planet formation processes.
Time.news Editor: The configuration of its surrounding environment sounds particularly complex. How do you think this misalignment and cleanliness in the protoplanetary disk will affect future research?
Dr. Madyson Barber: The unique structure of the disk around IRAS 04125+2902 b offers a rare chance to analyze how protoplanetary disks evolve and interact with forming planets. By studying its dynamics, we’ll learn more about the conditions necessary for planet formation and how young planets may migrate or influence their environments. This could lead to a deeper understanding of not just our solar system but also other planetary systems across the universe.
Time.news Editor: It sounds like the potential for new discoveries is enormous! As researchers continue to investigate this exoplanet, what questions remain unanswered that you hope to address in the next stages of your study?
Dr. Madyson Barber: There are several critical questions moving forward. For instance, we want to explore how the planet’s size and mass influence its atmospheric development and what specific chemical compositions we might find. Additionally, we are eager to understand the rate at which IRAS 04125+2902 b undergoes changes and how its environment drives these processes. Each of these aspects will help refine our models of planetary formation.
Time.news Editor: Dr. Barber, this has been an incredibly enlightening conversation. Your work not only contributes to the field of astrophysics but also sparks curiosity about our universe. Thank you for sharing your insights, and we look forward to learning more from your team’s future discoveries!
Dr. Madyson Barber: Thank you for having me! It’s exciting to share our findings, and I hope it inspires others to explore the wonders of space.
