Is the Universe Made of Math? Part 4: The Fire and the Filter
Like I said at the beginning, I’m not really keen on the idea of the mathematical universe. My own personal biggest objection stems from the whole point of occam’s razor: make things as simple as possible.
Astronomers Discover the First Galaxy-Wide Wobbling Black Hole Jet
Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have uncovered the largest and most extended stream of super-heated gas ever observed flowing from a nearby galaxy, providing the clearest evidence yet that a supermassive black hole can dramatically reshape its host galaxy far beyond its core.

A Quarter Century in Orbit: Science Shaping Life on Earth and Beyond
For more than 25 years, humans have lived and worked continuously aboard the International Space Station, conducting research that is transforming life on Earth and shaping the future of exploration. From growing food and sequencing DNA to studying disease and simulating Mars missions, every experiment aboard the orbiting laboratory expands our understanding of how humans can thrive beyond Earth while advancing science and technology that benefit people around the world.
Unlocking new cancer therapies from space NASA astronaut Christina Koch works on MicroQuin’s protein crystallization research aboard the International Space Station.NASA
The space station gives scientists a laboratory unlike any on Earth. In microgravity, cells grow in three dimensions, proteins form higher-quality crystals, and biological systems reveal details hidden by gravity. These conditions open new ways to study disease and develop treatments.
Astronauts and researchers have used the orbiting laboratory to observe how cancer cells grow, test drug delivery methods, and examine protein structures linked to diseases such as Parkinson’s and Alzheimer’s. One example is the Angiex Cancer Therapy study, which tested a drug designed to target blood vessels that feed tumors. In microgravity, endothelial cells survive longer and behave more like they do in the human body, giving researchers a clearer view of how the therapy works and whether it is safe before human trials.
Protein crystal growth (PCG) is another major area of cancer-related study. The NanoRacks-PCG Therapeutic Discovery and On-Orbit Crystals investigations have advanced research on leukemia, breast cancer, and skin cancers. Protein crystals grown in microgravity produce larger, better-organized structures that allow scientists to determine fine structural details that guide the design of targeted treatments.
Studies in orbit have also provided insights about cardiovascular health, bone disorders, and how the immune system changes in space—knowledge that informs medicine on Earth and prepares astronauts for long missions in deep space.
By turning space into a research lab, scientists are advancing therapies that benefit people on Earth and laying the foundation for ensuring crew health on future journeys to the Moon and Mars.
Farming for the future NASA astronauts Jessica Watkins and Bob Hines work on the eXposed Root On-Orbit Test System (XROOTS) space botany investigation, which used the station’s Veggie facility to test soilless hydroponic and aeroponic methods to grow plants. The space agricultural study could enable production of crops on a larger scale to sustain crews on future space explorations farther away from Earth.NASA
Feeding astronauts on long-duration missions requires more than packaged meals. It demands sustainable systems that can grow fresh food in space. The Vegetable Production System, known as Veggie, is a garden on the space station designed to test how plants grow in microgravity while adding fresh produce to the crew’s diet and improving well-being in orbit.
To date, Veggie has produced three types of lettuce, Chinese cabbage, mizuna mustard, red Russian kale, and even zinnia flowers. Astronauts have eaten space-grown lettuce, mustard greens, radishes, and chili peppers using Veggie and the Advanced Plant Habitat, a larger, more controlled growth chamber that allows scientists to study crops in greater detail.
These plant experiments pave the way for future lunar and Martian greenhouses by showing how microgravity affects plant development, water and nutrient delivery, and microbial interactions. They also provide immediate benefits for Earth, advancing controlled-environment agriculture and vertical farming techniques that help make food production more efficient and resilient in challenging environments.

Understanding how the human body changes in space is critical for planning long-duration missions. NASA’s Twins Study offered an unprecedented opportunity to investigate nature vs. nurture in orbit and on Earth. NASA astronaut Scott Kelly spent nearly a year aboard the space station while his identical twin, retired astronaut Mark Kelly, remained on Earth.
By comparing the twins before, during, and after the mission, researchers examined changes at the genomic, physiological, and behavioral levels in one integrated study. The results showed most changes in Scott’s body returned to baseline after his return, but some persisted—such as shifts in gene expression, telomere length, and immune system responses.
The study provided the most comprehensive molecular view to date of how a human body adapts to spaceflight. Its findings may guide NASA’s Human Research Program for years to come, informing countermeasures for radiation, microgravity, and isolation. The research may have implications for health on Earth as well—from understanding aging and disease to exploring treatments for stress-related disorders and traumatic brain injury.
The Twins Study demonstrated the resilience of the human body in space and continues to shape the medical playbook for the Artemis campaign to the Moon and future journeys to Mars.

The space station, which is itself an analog for deep space, complements Earth-based analog research simulating the spaceflight environment. Space station observations, findings, and challenges, inform the research questions and countermeasures scientists explore on Earth.
Such work is currently underway through CHAPEA (Crew Health and Performance Exploration Analog), a mission in which volunteers live and work inside a 1,700-square-foot, 3D-printed Mars habitat for about a year. The first CHAPEA crew completed 378 days in isolation in 2024, testing strategies for maintaining health, growing food, and sustaining morale under delayed communication.
NASA recently launched CHAPEA 2, with a four-person crew who began their 378-day simulated Mars mission at Johnson on October 19, 2025. Building on lessons from the first mission and decades of space station research, they will test new technologies and behavioral countermeasures that will help future explorers thrive during long-duration missions, preparing Artemis astronauts for the journey to the Moon and laying the foundation for the first human expeditions to Mars.
Keeping crews healthy in low Earth orbit NASA astronaut Nick Hague pedals on the Cycle Ergometer with Vibration Isolation and Stabilization (CEVIS), an exercise cycle located aboard the space station’s Destiny laboratory module. CEVIS provides aerobic and cardiovascular conditioning through recumbent or upright cycling activities.NASA
Staying healthy is a top priority for all NASA astronauts, but it is particularly important while living and working aboard the orbiting laboratory.
Crews often spend extended periods of time aboard the orbiting laboratory, with the average mission lasting about six months or more. During these long-duration missions, without the continuous load of Earth’s gravity, there are many changes to the human body. Proper nutrition and exercise are some of the ways these effects may be mitigated.
NASA has a team of medical physicians, psychologists, nutritionists, exercise scientists, and other specialized medical personnel who collaborate to ensure astronauts’ health and fitness on the station. These teams are led by a NASA flight surgeon, who regularly monitors each crew member’s health during a mission and individualizes diet and fitness routines to prioritize health and safety while in space.
Crew members are also part of the ongoing health and performance research being conducted to advance understanding of long-term spaceflight’s effects on the human body. That knowledge is applied to any crewed mission and will help prepare humanity to travel farther than ever before, including the Moon and Mars.
Sequencing the future NASA astronaut Kate Rubins checks a sample for air bubbles prior to loading it in the biomolecule sequencer. When Rubins’ expedition began, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbiting laboratory.JAXA (Japan Aerospace Exploration Agency)/Takuya OnishiIn 2016, NASA astronaut Kate Rubins made history aboard the orbital outpost as the first person to sequence DNA in space. Using a handheld device called the MinION, she analyzed DNA samples in microgravity, proving that genetic sequencing could be performed in low Earth orbit for the first time.
Her work advanced in-flight molecular diagnostics, long-duration cell culture, and molecular biology techniques such as liquid handling in microgravity.
The ability to sequence DNA aboard the orbiting laboratory allows astronauts and scientists to identify microbes in real time, monitor crew health, and study how living organisms adapt to spaceflight. The same technology now supports medical diagnostics and disease detection in remote or extreme environments on Earth.
This research continues through the Genes in Space program, where students design DNA experiments that fly aboard NASA missions. Each investigation builds on Rubins’ milestone, paving the way for future explorers to diagnose illness, monitor environmental health, and search for signs of life beyond Earth.

A Zombie Star Blows A Magnetic Wind
Gas and dust flowing from stars can, under the right conditions, clash with a star's surroundings and create a shock wave. Now, astronomers using the European Southern Observatory's Very Large Telescope (ESO's VLT) have imaged a beautiful shock wave around a dead star—a discovery that has left them puzzled. According to all known mechanisms, the small, dead star RXJ0528+2838 should not have such a structure around it. This discovery, as enigmatic as it's stunning, challenges our understanding of how dead stars interact with their surroundings.

NASA Welcomes Portugal as 60th Artemis Accords Signatory
Portugal is the latest nation to sign the Artemis Accords alongside 59 other countries in a commitment to advancing principles for the responsible exploration of the Moon, Mars, and beyond with NASA.
“Portugal joins a cadre of nations building the framework for safe, transparent, and prosperous activity in space,” said NASA Administrator Jared Isaacman in recorded remarks. “This is our generation’s Golden Age of Exploration. Together, we are advancing innovation, driving international collaboration, and discovering the secrets of the universe.”
Portugal’s Secretary of State for Science and Innovation Helena Canhão signed the Artemis Accords on behalf of the country on Jan. 11.
“2026 is the year in which humans will return to the Moon. It will mark the beginning of a new era of space exploration, reminiscent of the Portuguese explorers of the past, such as Magellan and his circumnavigation of our planet,” said Hugo Costa, executive director of the recently established Portuguese Space Agency, about the signing. “As a nation that approaches space sustainability with great care and responsibility, Portugal and the Portuguese Space Agency are proud to join the Artemis Accords and contribute to the sustainable, beneficial, and peaceful use of space for all humankind.”
A ceremony to recognize the signing was held on Monday in the capital city Lisbon, during a semi-annual meeting between the United States and Portugal to discuss cooperation between the two governments.
“This is a meaningful step forward for responsible space exploration,” said U.S. Ambassador to Portugal John J. Arrigo, who participated in the event. “Shared principles like those in the Artemis Accords are essential to ensuring that space remains a domain of stability, safety, and opportunity for all nations.”
In 2020, during the first Trump Administration, the United States, led by NASA and the U.S. Department of State, joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies.
The accords introduced the first set of practical principles aimed at enhancing the safety, transparency, and coordination of civil space exploration on the Moon, Mars, and beyond.
Signing the Artemis Accords means to explore peaceably and transparently, to render aid to those in need, to ensure unrestricted access to scientific data that all of humanity can learn from, to ensure activities do not interfere with those of others, to preserve historically significant sites and artifacts, and to develop best practices for how to conduct space exploration activities for the benefit of all.
More countries are expected to sign the Artemis Accords in the months and years ahead.
