What has Webb taught us about rocky exoplanets so far?
The hunt for potentially habitable rocky planets in our galaxy has been the holy grail of exoplanet studies for decades. While the discovery of more than 5,900 exoplanets in more than 4,400 planetary systems has been a remarkable achievement, only a small fraction (217) have been confirmed as terrestrial—aka rocky or “Earth-like.” Furthermore, obtaining accurate information on a rocky exoplanet’s atmosphere is very difficult, since potentially habitable rocky planets are much smaller and tend to orbit closer to their stars.
Thanks to next-generation instruments like the James Webb Space Telescope (JWST), exoplanet studies are transitioning from discovery to characterization. However, no atmospheres have been clearly identified around rocky planets yet, and the atmospheric data Webb has collected so far is subject to some uncertainty.
A summary of Webb’s findings was featured in a recent study by researchers from the Max Planck Institute for Astronomy (MPIA) and the Johns Hopkins University Applied Physics Laboratory (JHUAPL). Based on their summary, they recommend a “five-scale height challenge” to assist astronomers in atmospheric characterization.
Cosmic baby steps: For the first time, astronomers witness the dawn of a new solar system
For the first time, international researchers have pinpointed the moment when planets began to form around a star beyond the sun. Using the ALMA telescope, in which the European Southern Observatory (ESO) is a partner, and the James Webb Space Telescope, they have observed the creation of the first specks of planet-forming material—hot minerals just beginning to solidify. This finding marks the first time a planetary system has been identified at such an early stage in its formation and opens a window to the past of our own solar system.
“For the first time, we have identified the earliest moment when planet formation is initiated around a star other than our sun,” says Melissa McClure, a professor at Leiden University in the Netherlands and lead author of the new study, published in Nature.
Co-author Merel van ‘t Hoff, a professor at Purdue University, U.S., compares their findings to “a picture of the baby solar system,” saying, “We’re seeing a system that looks like what our solar system looked like when it was just beginning to form.”
Earth and Space for Educators
This FREE features Inspiration4 astronaut Chris Sembroski and educator Erin Duncan-Sembroski, along with your hosts, planetary scientist Dr. Kirby Runyon and space educator Dr. Mark Wagner. The high-energy one-hour session is focused on providing an overview of the three-day Earth and Space Experience coming up on November 7–9, 2025. Register now to learn about the geology at specific locations in Southern New Mexico, and how these sites are analogs for the Moon, Mars, and elsewhere in the solar system. Time is also allocated for a Q&A opportunity with all four speakers… come ready with questions! Participation in this also includes access to free space education resources that you can take back to share with your students or others in your community.
Note: This is appropriate for educators, industry professionals, and space enthusiasts from all walks of life. Space education is for everyone!
Chris “Hanks” Sembroski is a commercial astronaut, U.S. Air Force veteran, and passionate advocate for space exploration and STEM education. Best known for his role as Mission Specialist on the historic Inspiration4 mission in 2021, Sembroski spent three days in space, completing 47 orbits as part of the first all-civilian crew. With degrees in aeronautics and a career dedicated to advancing aerospace innovation, he has contributed to groundbreaking projects like Blue Origin’s New Glenn program and teaches as an adjunct faculty member at Embry-Riddle Aeronautical University. Chris’s journey reflects a lifelong passion for human spaceflight, from launching model rockets in college, leading teams through simulated missions at U.S. Space Camp, to advocating for space policy in Washington, D.C. He continues to inspire the next generation through his work as a speaker, educator, and industry leader, embodying the spirit of generosity and exploration.
Astronomers capture giant planet forming 440 light-years from Earth
Astronomers may have caught a still-forming planet in action, carving out an intricate pattern in the gas and dust that surrounds its young host star. Using ESO’s Very Large Telescope (VLT), they observed a planetary disc with prominent spiral arms, finding clear signs of a planet nestled in its inner regions. This is the first time astronomers have detected a planet candidate embedded inside a disc spiral.
“We will never witness the formation of Earth, but here, around a young star 440 light-years away, we may be watching a planet come into existence in real time,” says Francesco Maio, a doctoral researcher at the University of Florence, Italy, and lead author of this study, published on July 21 in Astronomy & Astrophysics.
Complex organic molecules found in young star’s disk hint at cosmic origins of life
Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers led by Abubakar Fadul from the Max Planck Institute for Astronomy (MPIA) has discovered complex organic molecules—including the first tentative detection of ethylene glycol and glycolonitrile—in the protoplanetary disk of the outbursting protostar V883 Orionis.
Scientists find Uranus is surprisingly warm, heating up the case for a new planetary mission
Scientists have found that Uranus is emitting its own internal heat — even more than it receives from sunlight — and this discovery contradicts observations of the distant gas giant made by NASA’s Voyager 2 probe nearly four decades ago.
Scientists led by Xinyue Yang of the University of Houston analyzed decades of readings from spacecraft and computer models to find that Uranus emits 12.5% more internal heat than the amount of heat it receives from the sun. However, that amount is still far less than the internal heat of other outer solar system planets like Jupiter, Saturn and Neptune, which emit 100% more heat than they get from the sun.
Pacific Northwest tech pioneers team up in quantum realms and on the space frontier
BELLEVUE, Wash. — Quantum physics and outer space may seem as different as two tech frontiers can be, but the challenges facing Pacific Northwest ventures that are aiming to make their fortune on those frontiers are surprisingly similar.
Amid the current turbulence on the national political scene, it’s getting harder to capture the attention — and gain the support — of the federal government, which has historically been the leading funder of research and development. And that means it’s more important than ever for researchers, industry leaders and local officials to join forces.
“Think of it as a triad,” said Jason Yager, executive director of the Montana Photonics and Quantum Alliance, which is one of the beneficiaries of a $41 million Tech Hub grant awarded by the federal government a year ago. “If all of these pieces are working together, then where they meet is socio-economic growth, and then you’re ready to bring in the additional funding to launch that.”
