The 22nd Annual International Astrophysics Conference (AIAC), held this year in the historic city of Santiago de Compostela, Spain, brought together leading scientists from across the globe to discuss the latest breakthroughs and challenges in solar wind and local interstellar medium physics. The conference, known for its focus on the universality of physical processes in space plasma physics, drew researchers, students, and mission scientists for a week of presentations, collaboration, and enlightened dialogue.

At this year’s conference, there were exciting updates from several space missions, including (PSP), which completed its closest-ever approach to the Sun on December 24, 2024. This landmark event, along with the upcoming (IMAP) and missions, served as focal points for many of the presentations and discussions.

“There were very exciting results from the NASA Parker Solar Probe mission that is exploring the deepest parts of the Sun's atmosphere,” says Dr. Gary Zank, the director of the Center for Space Plasma and Aeronomic Research (CSPAR), the Aerospace Rocketdyne endowed chair of the Department of Space Science (SPA) at the University of Alabama in Huntsville (UAH), and the director of AIAC. “These exciting results are shedding light on how the atmosphere of the Sun is heated to well over 1 million degrees, which has been an enduring mystery for over 100 years. Several of our UAH scientists and students were deeply involved in some of these results.”

The AIAC emphasized how distinct yet complementary missions are reshaping our understanding of the Sun and its environment. Zank noted that while Parker Solar Probe investigates the solar wind’s origins near the Sun, IMAP will observe related phenomena near Earth, offering insights into space weather that impacts satellite operations and global communications.

“These are all entirely different missions,” Zank explained. “Parker Solar Probe is exploring the origins of the solar wind, including the generation of shock waves, structures, the driving of magnetized turbulence, accelerating highly energetic particles,and more. All of these will be measured and observed by IMAP at the location of the Earth, and this will feed into our deeper understanding of Space Weather.”

Zank says this has important implications for Earth-bound satellites that are important for communications, navigation, military situational awareness and more. “IMAP is also exploring the boundaries of the solar wind where the solar wind meets the local interstellar medium, which has nothing to do with PSP.”

“HelioSwarm, on the other hand, will be exploring the nature of magnetic turbulence in the solar wind at very small scales. This is typically created in situ by larger scale processes within the solar wind, and these can originate low in the Sun's atmosphere where PSP is exploring,” Zank explained. “Furthermore, HelioSwarm is a configuration of 9 spacecraft unlike the single IMAP and PSP spacecraft, meaning that the kinds of measurements, multi-point, will be completely different. So all of these considerations informed and influenced conversations and scientific directions at the AIAC.”

One of the defining themes of AIAC -  the universality of physical processes such as turbulence, magnetic reconnection, and shock acceleration - was clearly reflected throughout the presentations.

“Certain processes such as turbulence and magnetic reconnection or particle acceleration by shock waves or magnetic islands exist throughout the universe and not just in the solar wind or the Sun's atmosphere,” Zank says. “These processes occur around other stars, in the interstellar medium, and even in different galaxies.”

The conference served as a launchpad for new collaborations and interdisciplinary exploration, fostering a dynamic exchange of ideas between early-career researchers and seasoned experts.

“Collaborations and interdisciplinary work are a feature of a conference of this kind -- the meeting is designed to facilitate students and researchers engaging and discussing their work and identifying areas of common interest and where progress and new breakthroughs can be made," says Zank.

Held in Santiago de Compostela, the location itself added to the unique atmosphere of the meeting.

“By being located in a single hotel and having the opportunity to meet in a beautiful, vibrant and culturally rich city means people from all scientific backgrounds and fields want to attend the meeting. This allows one to create a scientifically highly diverse meeting which makes transdisciplinary interactions possible,” Zank says.

Looking ahead, the AIAC is already setting its sights on new frontiers in heliophysics and interstellar studies.

“Every spacecraft that goes to a new region or environment or makes new kinds of measurements, whether multipoint or at unexplored scales, will make exciting discoveries that create new frontiers,” Zank says. “NASA's IMAP will launch in September of this year and we can expect groundbreaking discoveries almost immediately. This will undoubtedly be a major theme of next year's AIAC meeting.”

Zank also shared words of encouragement for prospective students eyeing careers in space science.

“As evidenced by the number of students applying to the program, the opportunities to attend meetings like the AIAC, to be constantly at the frontiers of space science research working with world-class faculty make the Space Science graduate program one of the most exciting programs in the world,” he says.

With fresh insights and collaborative spirit, the global scientific community at the 22nd AIAC once again affirmed its reputation as a cornerstone event in the field of space physics.

The Solar Wind Electrons Alphas and Protons (SWEAP) instrument suite developed by researchers at The Harvard Smithsonian Center for Astrophysics, �������� (UAH) and the Marshall Space Flight Center for NASA’s Parker Solar Probe (PSP) has helped the PSP earn the coveted 2024 Robert J. Collier Trophy.

Speakers at the inaugural Dr. Martin Luther King Jr. Leadership Breakfast, presented by �������� (UAH), offered messages of economic innovation, growth and cooperation to the capacity audience.

Syed Ayaz, a researcher at �������� (UAH), has published a paper in Scientific Reports that builds on an earlier first-of-its-kind study that examined kinetic Alfvén waves.

The National Space Club (NSC), Huntsville Chapter, has selected Dr. Gary Zank at �������� (UAH) to receive the 2024 Distinguished Science Award.

The first Annual International Alabama Plasma Physics Conference (AIAPC), which is directly connected to statewide efforts to establish plasma science and engineering (PSE) as a major Alabama industry, is coming to Huntsville Oct. 28-30.

Future Technologies & enabling Plasma Processes (FTPP), a National Science Foundation (NSF) grant program led by �������� (UAH), a part of the University of Alabama System, has been awarded Program of the Year as part of the 2024 256Today.

Dr. Mehmet Sarp Yalim, a research scientist in the Center for Space Plasma and Aeronomic Research (CSPAR) at �������� (UAH), a part of the University of Alabama System, has won a $608,000 National Science Foundation (NSF) Solar, Heliospheric, and INterplanetary Environment (SHINE) grant to study a process known as Joule, or Cowling, heating.

Two scale models of spacecraft that provide research data to �������� (UAH) Center for Space Plasma and Aeronomic Research (CSPAR) have joined a Parker Solar Probe model on prominent display at CSPAR offices in Cramer Research Hall, thanks to a UAH alumnus who caught the modeling bug at age 4.

HUNTSVILLE, Ala. () — Blake Parker, a NASA engineer returned Wednesday to the campus where his space exploration dreams began to provide a special gift for UAH’s Center for Space Plasma and Aeronomic Research (CSPAR).

The 2013 UAH graduate hand-made two spacecraft models with just a few materials, one being the Interstellar Boundary Explorer or IBEX and the Voyager which provided scientists with vital knowledge about our solar system.

Parker’s donation is much more than research products that’ll be put on display for students. It’s more about showing them they too can dream big while aiming for the stars in an inspirational node by someone who started in the same CSPAR program current ��������s are participating in.

“It’s great having an actual physical representation of the thing you’re working on and being able to get the idea like what does this thing actually look like,” Parker said. “It’ll give them an idea of what they’re working toward and being like this is that instrument and where it’s related to the others on the actual spacecraft itself.”

UAH’s CSPAR program Director Gary Zank says it means the world to see former students like Parker coming back to show students they too are able.

“The time, the effort that he spends building these kind of spacecrafts he probably does realize it but for students and even for people like me who spent their lifetime working on these kinds of missions, having something tangible to attach your hat to your mental vision is tremendously beneficial,” Zank said. “I’d like to thank Blake for making all of that possible with these models.”

Life as an engineer has provided Parker with a platform to live out his dream and now he’s showing others they too can have a career in space exploration that has no limits.

“It feels really great just getting to show where the possibilities can go, it’s possible if you work hard enough, then you can make it,” Parker told News 19.

Parker’s scale model spacecraft joins another model spacecraft he donated in 2020 that’s now on display at UAH’s Cramer Research Hall.
