Newly-Discovered Interstellar Comet is Billions of Years Older Than the Solar System
All eyes are on the newly discovered interstellar object 3I/ATLAS, currently inbound to the inner solar system. Initial observations have revealed that it's rich in water ice, and it's believed that it originated from the Milky Way's thick disk, ancient stars that orbit above and below the galactic plane. This could mean that 3I/ATLAS is billions of years older than the Solar System, the oldest comet ever discovered. It should reveal more as it heats up and outgasses as it gets closer to the Sun.
Synthetic Biology Could Support Future Outposts on the Moon and Mars
When we leave Earth, we have to bring everything with us, from the air we breathe to the food we eat. For example, a 6-person, 1000-day mission might require 108 tonnes of food. In a new paper, researchers suggest ways that synthetic biology could allow us to convert local resources, regenerate resources in closed-loop environments, protect explorers from radiation, and create custom medicine on demand to support long-term space exploration.
The Habitable Worlds Observatory Could Find More Very Massive Stars
Very massive stars (VMSs)have had a massive impact on the formation of our universe. However, there aren’t very many of them, with only around 20 known specimens in the Milky Way and Large Magellanic Cloud. Even observing those is difficult for the current generation of telescopes, which is where an unexpected technological champion might play a role. According to a new paper by Fabrice Martins of CNRS and a group of European and American researchers, the upcoming Habitable World Observatory (HWO) might be our most useful tool when it comes to finding these elusive giants.
Satellite Constellations Are Too Bright, Threatening Astronomy and Our Night Sky
Our quest for universal internet is stealing the stars. Thousands of satellites now travelling across the night sky are far brighter than international safety limits, turning what was once humanity's window to the cosmos into a highway of artificial lights. New research reveals that major constellations like Starlink and OneWeb are breaking the brightness rules designed to protect both cutting edge astronomy and the simple joy of stargazing potentially robbing future generations of the dark skies that have inspired wonder for centuries.
Scientists Solve 400 Year Old Solar Mystery
For over four centuries, the dark blemishes on our Sun's surface have puzzled astronomers. Now, German scientists have cracked the code behind sunspot stability, revealing how these Earth sized magnetic monsters, each powerful enough to rival an MRI machine yet spanning areas larger than our entire planet, maintain their grip on the solar surface for weeks or months at a time. This breakthrough not only solves one of astronomy's oldest mysteries but could revolutionize our ability to predict the explosive solar storms that threaten our satellite dependent world.
Earth Was Born With Water; No Delivery Needed
The source of Earth's water is one of the most compelling questions facing scientists. Earth's habitability depends on multiple factors, but water is the basis for life, and it had to come from somewhere. Did comets and meteorites deliver it after Earth formed? Or did water become part of our planet as it formed?
A Lunar Base Could Start with a Dome over a Crater Made of Regolith
When astronauts live on the Moon permanently, they're going to need a safe habitat, ideally made out of local construction material. A new paper suggests that lunar astronauts could cover a 17-meter crater with a dome made from a lunar regolith-based geopolymer. A 3D printer would extrude a paste made of lunar regolith that would be sintered together into the shape of the dome. This would provide protection from radiation and could even maintain a pressurized habitat.
This Earth-sized Exoplanet is On a Death Spiral
An international team of astronomers have discovered an Earth-size exoplanet on a very tight orbit around its star. It completes an orbit in only 5 hours and 22 minutes. Unfortunately, the planet will either be torn to pieces or crash into its star in about 31 million years.

Space Station Crew Celebrates Milestone
Space Station Crew Celebrates Milestone
In this June 13, 2025, photo, NASA astronaut Anne McClain shows off a hamburger-shaped cake to celebrate 200 cumulative days in space for JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi since his first spaceflight as an Expedition 48-49 Flight Engineer in 2016.
Onishi and McClain launched to the International Space Station along with NASA astronaut Nichole Ayers and Roscosmos cosmonaut Kirill Peskov on March 14, 2025, as part of the Crew-10 mission. Aboard the orbital laboratory, the Crew-10 members conduct scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. McClain and Ayers also performed a spacewalk on May 1, 2025 – McClain’s third and Ayers’ first.
Check out the International Space Station blog to follow the crew’s research and other activities.

Registration Opens for 2025 NASA International Space Apps Challenge

Preparations for Next Moonwalk Simulations Underway (and Underwater) A team works together on their project during the 2024 NASA Space Apps Challenge event in in Arequipa, Peru. Teams have two days to respond to the challenges and submit their project for the chance to win one of 10 global awards.

NASA invites innovators of all ages to register for the NASA Space Apps Challenge, held on Oct. 4-5. The 2025 theme is Learn, Launch, Lead, and participants will work alongside a vibrant community of scientists, technologists, and storytellers at more than 450 events worldwide. Participants can expect to learn skills to succeed in STEM fields, launch ideas that transform NASA’s open data into actionable tools, and lead their communities in driving technological innovation.
During the NASA Space Apps Challenge, participants in the U.S. and around the world gather at hundreds of in-person and virtual events to address challenges authored by subject matter experts across NASA divisions. These challenges range in complexity and topic, tasking participants with everything from creating machine learning models and leveraging artificial intelligence, to improving access to NASA research, to designing sustainable recycling systems for Mars, and to developing tools to evaluate local air quality here on Earth.
Dr. Yoseline Angel Lopez, a former space apps challenge winner and now an assistant research scientist at NASA’s Goddard Spaceflight Center in Greenbelt, Maryland, can attest that the opportunity to Learn, Launch, Lead goes far beyond the hackathon.
“The NASA Space Apps Challenge gave me and my team a meaningful opportunity to apply science to real-world problems and gain validation from NASA scientists and industry experts,” said Angel.
In 2021, her team’s winning web-app prototype was adopted by Colombia’s Ministry of Agriculture, connecting smallholder farmers with local buyers. The platform also supported agricultural land-use monitoring using satellite imagery.
After the hackathon, project submissions are judged by NASA and space agency experts. Winners are selected for one of 10 global awards.
“Participating in the hackathon is exciting on its own. But when your project can lead to greater opportunities and make a difference in your community, that’s a dream come true,” said Angel. She will return to the 2025 hackathon as a NASA subject matter expert and challenge author, giving a Golden Age of innovators the opportunity to make a difference in their communities through the use of data from NASA and 14 space agency partners.
This year’s partners include: Bahrain Space Agency; Brazilian Space Agency; CSA (Canadian Space Agency); ESA (European Space Agency); ISRO (Indian Space Research Organisation); Italian Space Agency; JAXA (Japan Aerospace Exploration Agency); Mohammed Bin Rashid Space Centre of the United Arab Emirates; National Space Activities Commission of Argentina; Paraguayan Space Agency; South African National Space Agency; Spanish Space Agency; Turkish Space Agency; and the UK Space Agency.
NASA Space Apps is funded by NASA’s Earth Science Division through a contract with Booz Allen Hamilton, Mindgrub, and SecondMuse.
