JWST study reveals how rare exoplanet pair formed
MIT study uses JWST to decode a rare exoplanet system, revealing how mini-Neptunes form beyond the frost line.
Astronomers have uncovered fresh clues about how distant worlds form, thanks to a new JWST mini-Neptune study that examines a rare planetary system 190 light years away. Using NASA’s powerful space telescope, researchers analysed the atmosphere of a small gas planet orbiting unusually close to its star — and found evidence that challenges long-held assumptions about where such planets originate.
In a discovery that’s quietly reshaping how astronomers think about planet formation, scientists have uncovered new clues behind one of the Milky Way’s strangest planetary pairings — a hot Jupiter and a mini-Neptune orbiting the same star.
The finding by scientists from MIT, based on observations from NASA’s James Webb Space Telescope (JWST), suggests that these two unlikely neighbours didn’t form where they are today. Instead, they likely began life much farther out in their star system and gradually migrated inward — staying together against the odds. The study, appeared in The Astrophysics Journal of Letters, reveals new measurements of the mini-Neptune’s atmosphere.
JWST mini-Neptune study : A rare planetary pairing
The system, located about 190 light years from Earth, has puzzled astronomers since its discovery in 2020. Hot Jupiters — massive gas giants that orbit very close to their stars — are usually “lonely,” with no nearby planetary companions.
But this one breaks the rule.
“This is the first time we’ve observed the atmosphere of a planet that is inside the orbit of a hot Jupiter. This measurement tells us this mini-Neptune indeed formed beyond the frost line,” says Saugata Barat, a postdoc in MIT’s Kavli Institute for Astrophysics and Space Research and the lead author of the study.
“This was a one-of-a-kind system,” Chelsea X. Huang, faculty at University of South Queensland, said in a media statement, explaining how such massive planets typically scatter away anything inside their orbit.
Yet in this case, a smaller mini-Neptune somehow survives closer to the star, orbiting every four days, while the hot Jupiter circles every eight.
Back in 2020, Chelsea Huang — then a Torres Postdoctoral Fellow at MIT — spotted something unusual: a mini-Neptune orbiting its star alongside an unexpected companion, a hot Jupiter.
JWST captures a crucial clue
To understand how this system formed, researchers from MIT and international institutions turned to JWST, focusing on the inner planet, TOI-1130b.
What they found was telling.
The mini-Neptune’s atmosphere is unusually “heavy,” rich in water vapour, carbon dioxide, sulfur dioxide, and traces of methane — a composition that shouldn’t exist if the planet formed close to its star.
JWST mini-Neptune study : Rethinking planet formation
That “frost line” — the region in a young star system where temperatures are low enough for ice to form — appears to be central to the story.
Scientists now believe both planets likely formed in this colder, outer region, where icy materials helped build dense atmospheres. Over time, they migrated inward together, maintaining their unusual orbital arrangement.
The findings challenge earlier assumptions that mini-Neptunes forming close to stars should have lighter atmospheres dominated by hydrogen and helium.
A system that shouldn’t exist — but does
Even observing the system was no easy task. The two planets are in what astronomers call a “mean motion resonance,” subtly tugging at each other’s orbits and making their movements harder to predict.
“It was a challenging prediction, and we had to be spot-on,” Barat said, referring to the effort required to time JWST’s observations precisely.
JWST mini-Neptune study : Why this matters
Mini-Neptunes are among the most common planets in the galaxy, yet none exist in our own solar system — making them both familiar and mysterious.
This study, appeared in Astrophysical Journal Letters, offers the clearest evidence yet that such planets can form far from their stars and migrate inward, carrying their atmospheres with them.
“This system represents one of the rarest architectures that astronomers have ever found,” Barat said in a media statement.
And in a universe full of planets, that rarity might just hold the key to understanding how many of them — including worlds very different from our own — come to be.

India’s Moonshot Moment: Can New Delhi Turn Orbit Into Influence
India’s space mission is entering a new era, from Gaganyaan and space stations to private startups, space diplomacy and national security.
Gaganyaan is only the beginning. India’s space mission faces new opportunities and challenges as human spaceflight, diplomacy, private industry and security reshape its ambitions beyond Earth.
Indian human space programme Gaganyaan is mooted by Indian Space Research Organisation. This ambitious space mission aims to send Indian astronauts in Outer Space indigenously by the proactive leadership of the Indian government. India as a leading space power of the world aims to demonstrate her space capabilities and research in the final frontier. The Gaganyaan mission is the dream of 1.4 billion Indians. The programme will be initiated in 2027 creating a historic mark in the collective space exploration journeys. This is a stepping stone as NASA is envisioning to make Moon as the next base for active space programmes by 2030.
According to NASA this spectacular feat will be achieved soon within 3 years. NASA has asked India’s ISRO to join for the permanent Lunar base in the south pole of Moon. Here comes the significance of Indo-US space partnership and how India will navigate through the space diplomacy keeping in mind of Indian dream of Bharatiya Antariksh Station and the long lasting commitment to strategic autonomy and an independent foreign policy. India already signed the Artemis accords in June 2023. If India is ready to be part of this initiative, it will mark the beginning of a new era in India-United States space cooperation. The question is how India will navigate this process, protecting its sovereignty and national interest while engaging with NASA to help build a new civilisation of space travellers on the lunar surface. According to media reports India’s spectacular success with the Chandrayaan missions has led the United States to choose India as a natural partner, inviting it to join space exploration programmes on the Moon.
India’s Space Mission: The Next Frontier of Global Power

The Gaganyaan mission is significant for strengthening Indian space station’s vision. The Bharatiya Antariksh Station is an Indian space station which is a symbol of Indian space nationalism and a centre for joint research with friendly nations. India is actively pushing for space diplomacy and it is evident from the trainings received by Gaganyaan crew members. They have trained in Russia and the United States, continuing India’s commitment to strong bilateral ties with both Cold War-era rivals. Space exploration and travel are combined with diplomacy, as Indian foreign policy in a multipolar world order pushes for strong partnerships with both Russia and the United States.
Indian Air Force veteran Wing Commander Rakesh Sharma was the first Indian cosmonaut to reach the final frontier, in a Soviet space mission. Following this historic feat, Kalpana Chawla and Sunita Williams travelled to outer space on American missions. Recently, Group Captain Shubhanshu Shukla represented India in the Axiom mission successfully travelling to International Space Station and returned safely as a national hero. He is also part of the Gaganyaan mission. Colonel Anil Menon, who is part of the US Space Force, is also now in outer space. He has strong Indian connections, making him the first astronaut with roots in Kerala to explore the domain of outer space.
With privatisation in outer space in India, Skyroot Aerospace, a private company based in Hyderabad, successfully launched Vikram-1 rocket to low Earth orbit. Thus India is taking leverage of the infinite possibilities chasing stars and galaxies. Indian space ambitions are at a historic juncture now, with over 400 private Space startups. Another mission is aiming for a reusable re-entry vehicle, targeted for launch in 2027, building on ISRO’s success with the Pushpak mission, the Reusable Launch Vehicle Landing Experiment, in 2024.

However, there are concerns in India’s space sector, with many ISRO scientists seeking early retirement. The efficiency of major projects like Aditya and Gaganyaan should not be affected by this. Former ISRO Chairman G Madhavan Nair shared his concerns with the media about bureaucratisation within the organisation. ISRO is a symbol of India’s space story which is filled with resilience and strength of great visionary leaders like Dr Vikram Sarabhai and Dr APJ Abdul Kalam. Unfortunately, there have been budgetary cuts to major ISRO space projects. The government’s focus on Viksit Bharat, a holistically developed India, is only possible with investment in science and technology, and in-depth research in the domain of outer space.
Outer space is militarised, and the race for resource nationalism is a reality. For India to emerge as a global power, investment in space exploration is inevitable. Nations are increasingly aware of the strategic use of outer space for securing national interests. Satellites with civilian and national security purposes are critical assets of any nation. India too has many civilian and strategic assets in outer space, and protecting these is the responsibility of the government. The anti-satellite test Mission Shakti is a milestone demonstrating India’s hard-power capabilities in outer space. Some nations have capabilities such as laser-guided weapons, which can disable or destroy an enemy’s assets during conflict. Space is a key domain for ensuring seamless communication and intelligence-sharing during both war and peace.
Intelligence and surveillance are key factors in winning the wars of the present and future. The dominance in space technology and information superiority will determine the victories of nations fighting for their national interest.
In India, the share of higher education in the annual budgetary allocation remains low. A young generation passionate to explore arenas of space science is to be inculcated with the right mindset. Allocation of funds in education sector is a key requirement for building a strong India with educated and skilled youth. ISRO’s active collaboration with 100 Atal Tinkering Labs is a positive step in inculcating the spirit of scientific enquiry at the grassroots level. Support and encouragement for students in the creative arts and sciences is the need of the hour. Atal Tinkering Labs and India’s startup ecosystem can achieve greater synergy, ensuring a seamless transition from school life to entrepreneurship, from plan to execution.
Human activity has actively degraded the ecosystem, impacting life on both land and water. Now, with active competition in the arena of outer space, space debris is a serious global security challenge. This debris travels swiftly in outer space, damaging active space assets including civilian and defence satellites. The young budding scientists of India need to re-invent and discover practical solutions to the pressing global challenge of space debris and work with relentless passion for making a strong and stable India.

Meteorite Dust Reveals Evidence of Magnetic Field in the Young Solar System
A magnetic field in the early solar system has been detected in ancient meteorite grains, offering evidence that magnetism helped shape the young sun.
Ancient grains in an Antarctic meteorite reveal evidence of a magnetic field in early solar system, suggesting magnetism helped shape the young sun
Tiny mineral grains preserved inside an ancient meteorite have recorded evidence of a magnetic field that existed during the earliest stages of the solar system, suggesting that magnetism, alongside gravity, helped shape the young sun and its surrounding disk of gas and dust.
Ancient Meteorite Records Reveal a Magnetic Field in the Early Solar System
Scientists at the Massachusetts Institute of Technology (MIT) examined microscopic grains in a meteorite recovered from Antarctica and found traces of ancient magnetism dating to the first 200,000 years of solar system history. The findings provide what researchers describe as the earliest known evidence of a magnetic field in the infant solar system.
The study, published in the Proceedings of the National Academy of Sciences, challenges the view that gravity alone drove the transformation of the early solar system from a cloud of gas and dust into a flattened disk that eventually produced the sun and planets.
“This transition, from a spherical cloud to a protoplanetary disk, is one of the most significant events in all of solar system history,” said Benjamin Weiss, professor of Earth and Planetary Sciences at MIT, in a statement issued. Measurements from the study, he said, indicate that magnetism likely played a role.
Magnetic records preserved in meteorite grains
The researchers studied DOM 08006, a primitive meteorite discovered in 2008 in the Dominion Range of Antarctica. The meteorite contains calcium-aluminum-rich inclusions, or CAIs, which formed during the earliest period of solar system development.
CAIs are among the oldest known solid materials from the solar system. Some of the grains contain magnetic minerals that can preserve the imprint of a magnetic field present when they formed.
The team isolated tiny grains from the meteorite and subjected them to a series of tests to determine whether they retained remanent magnetisation — a lasting record of an earlier magnetic field.
The researchers found evidence of a magnetic field with an estimated strength of about 150 to 600 microteslas. That is roughly three to 12 times stronger than Earth’s magnetic field today.
The preservation of these records was possible because DOM 08006 appears to have undergone relatively little alteration during its long history.
“Other meteorites went through many different processes over this 4.5 billion year history,” Weiss said. “But somehow, DOM has experienced less alteration than any other meteorite.”
Magnetism before the planets
Scientists already had evidence of magnetic fields in the solar system several million years after its formation, when the sun had formed and the planets were beginning to take shape.
The new measurements push that evidence much further back — to a period when the solar system was still a collapsing cloud of gas and dust and the sun itself was beginning to form.
In the early solar system, electrically charged particles moving through the developing disk could have generated a magnetic field. That field may then have influenced the movement of gas and material towards the central star.
The researchers argue that magnetism therefore needs to be considered alongside gravity when reconstructing how the early solar system evolved.
“We think these kinds of magnetic fields were helping to move gas from the protoplanetary disk, in toward this central star, the sun,” said Cauê Borlina, the study’s first author and now an assistant professor at Purdue University.
The findings do not replace gravity as the main force shaping the early solar system. Instead, they suggest that magnetic fields were another important part of the physical processes that brought material together and helped the young sun grow.
The study was led by Borlina, with Weiss, Elias Mansbach and Nilanjan Chatterjee of MIT, along with researchers from Tsinghua University, the University of Cambridge, Caltech and the University of California, Los Angeles

NASA Puts $500,000 Prize on Better Satellite Tracking
NASA is offering up to 500,000 dollars to develop affordable technology that can improve satellite tracking by measuring atmospheric drag in low Earth orbit. The effort aims to help operators predict orbital changes more accurately as solar activity alters the thin upper atmosphere.
A faint layer of air high above Earth is becoming an important concern for satellite tracking operators. NASA is now offering up to USD 500,000 to individual winning teams that can develop a practical way to monitor it. The US space agency opened the Orbital Clarity Challenge on August 19, asking researchers and companies to develop instruments that can determine how much drag spacecraft experience in low Earth orbit. Up to four teams can win the top prize, taking the potential total award to USD 2 million.
The focus is the thermosphere, a region that begins about 80 kilometres above Earth and extends hundreds of kilometres into space. The air here is extremely sparse, but spacecraft moving through it still encounter enough resistance to gradually alter their orbits.

That resistance does not remain constant. When the Sun becomes more active, bursts of energy can heat the upper atmosphere. The thermosphere expands, increasing the amount of gas encountered by satellites. The resulting increase in drag can change their altitude and make their future position harder to calculate. For spacecraft operators, even a small difference can matter when several objects are moving through the same orbital region.
A Gap in the Data
NASA already relies on computer models to estimate atmospheric drag. But those calculations depend on how well scientists understand conditions in the upper atmosphere at a particular time and location. The agency wants new technology that can provide more direct information.
Under the competition, proposed instruments should be inexpensive enough to be deployed widely. NASA says they could potentially be carried aboard commercial spacecraft as hosted payloads, allowing measurements to be collected from several points in orbit rather than from a limited number of dedicated missions.
The competition will run through several stages, with NASA aiming to move successful ideas from an initial concept towards an instrument that can eventually be tested in space. Winning teams are also expected to receive an opportunity for an orbital demonstration. Applications for the first stage close in November 2026.
Satellite Tracking: Why this Matters?
The number of spacecraft operating in low Earth orbit has grown rapidly, with satellites supporting communications, navigation, Earth observation and scientific research.
Their paths are affected by several forces, including the thin atmosphere at orbital altitude. During periods of strong solar activity, atmospheric drag can rise sharply and contribute to changes in orbital altitude. Better information about those changes could help operators plan manoeuvres more accurately and improve forecasts of when satellites will descend from orbit.
NASA’s prize is therefore aimed at a relatively small piece of the space infrastructure puzzle: getting a clearer picture of the air that satellites are still moving through, even hundreds of kilometres above the ground.
