The search for planets beyond our solar system has become one of the most active research areas in modern science. With more than 5,000 confirmed exoplanets and counting, researchers are now probing questions of planetary formation, orbital dynamics, and habitability at an unprecedented scale.
At the University, this global scientific effort is no longer confined to just major observatories or traditional brick-and-mortar educational institutions. Through the Exoplanet Research Program, our online students are actively participating in professional-grade astronomical research.
They are also developing technical, analytical and collaborative skills that extend far beyond astrophysics. These transferable skills will serve them well in the future.
What Is the Exoplanet Research Program?
The Exoplanet Research Program was designed to address a central challenge in distance education: how to provide authentic, hands-on research experiences in a fully online environment. Rather than relying on simulated data or passive learning, this program integrates students directly into an exoplanet research team. Participants perform various activities, such as:
- Analyzing observational data
- Conducting photometric measurements
- Collaborate in structured research teams that mirror professional scientific groups
The team meets weekly to discuss progress, troubleshoot analyses and review results. In addition, there is periodic oversight from faculty advisors. This structure ensures scientific accountability and also enables students from diverse geographic locations to work together seamlessly.
How Are Exoplanets Found?
At the core of the Exoplanet Research Program is transit photometry, one of the most productive methods for detecting and characterizing exoplanets. When a planet passes in front of its host star, it causes a subtle but measurable dip in brightness.
Extracting meaningful information from these fluctuations requires precision, rigorous methodology, and careful statistical treatment. The program enables students to develop these skills firsthand.

How Does the Exoplanet Research Program Work?
Targets for student research are typically selected from the Transiting Exoplanet Survey Satellite (TESS), NASA’s space telescope for identifying exoplanets. Students in the Exoplanet Research Program evaluate the observational feasibility of research targets, calculate their visibility windows and prioritize targets using a flexible schedule developed by the team. The emphasis is on repeat observations, reproducibility and data verification.
This planning phase is critical. It teaches participants how observational constraints such as sky position, timing and telescope availability shape real-world research decisions.
The observations are conducted through the Dr. Wallace E. Boston Observatory’s telescope and the global iTelescope network. This network gives our University’s students access to telescopes located across multiple continents.

Once data regarding research targets is acquired, team members perform standard photometric calibration procedures, including bias, dark and flat-field corrections. These steps – often glossed over in introductory coursework – are essential for removing instrumental noise and ensuring data integrity.
The light curves of that research are then extracted using professional software tools, such as AstroImageJ and NASA’s EXOplanet Transit Interpretation Code (EXOTIC). Both types of software are widely used in the exoplanet research community.

The analysis continues in Python-based environments, where students model stellar flux variations (changes in a star’s luminosity), estimate transit parameters and quantify uncertainty by determining the range of values within which the true parameters are likely to lie.
This workflow introduces participants to coding practices, data visualization and error analysis that align closely with contemporary astrophysical research standards. In addition, the emphasis on reproducibility ensures that results can be independently validated – a cornerstone of scientific credibility.
Scientific rigor is reinforced through internal peer review. Exoplanet Research Program team members will:
- Evaluate each other’s analyses
- Compare their findings against publicly available datasets
- Identify discrepancies before results are finalized
This process improves data quality. Also, it teaches students how professional scientists critique, refine, and defend their work.
What Are the Benefits of the Exoplanet Research Program for Team Members?
The collaborative nature of the Exoplanet Research Program mirrors modern scientific research culture, where interdisciplinary teams and distributed workflows are the norm. Students on the team must communicate clearly, document their methodologies, and present their findings in a form suitable for publication or conference presentation. These experiences translate directly into skills valued in science, technology, engineering, and math (STEM) careers, ranging from engineering and data science to systems analysis and project management.
The Exoplanet Research Program has demonstrated consistent success in detecting and modeling exoplanet transits with scientifically acceptable precision for small-telescope photometry. Student-generated lightcurves meet professional benchmarks and support the broader effort to confirm and refine TESS exoplanet candidates.
For students, the educational outcomes are equally important. Research team members have shown measurable improvement in:
- Programming proficiency
- Statistical reasoning
- Scientific writing
By working with real data and real uncertainty – rather than prepackaged exercises – students develop confidence in their ability to solve complex, open-ended problems.
Beyond its contributions to exoplanet science, the Exoplanet Research Program serves as a proof of concept (feasibility) for scalable research conducted remotely. It challenges the assumption that meaningful observational science requires physical proximity to a campus observatory or a laboratory. Instead, the program demonstrates how remote-access telescopes, open-source software and structured mentorship can make participation in high-level research more democratic.
This research experience is particularly significant for the University’s nontraditional students, which includes working professionals, military-affiliated learners and students in geographically remote locations. By integrating this type of research directly into a distance learning framework, the University expands access to experiences that were once limited to a small subset of students.
As exoplanet science continues to evolve, small-telescope photometry will remain a vital component of exoplanet candidate verification and long-term monitoring. The Exoplanet Research Program is well positioned to contribute to this effort while continuing to refine its educational mission.
Future directions for this program aim to deepen student engagement with advanced modeling techniques, expand publication opportunities, and further integrate research outcomes into the broader astrophysics community. In an era where data-driven discovery defines scientific progress, the Exoplanet Research Program demonstrates how education and research can advance together.
By turning distant starlight into actionable data – and students into scientists – the Exoplanet Research Program underscores a simple but powerful idea. The frontier of discovery is no longer defined by physical location, but by access, curiosity and collaboration.
