A swarm of galaxies called the Bullet Cluster is the biggest, best natural laboratory for studying dark matter that astronomers have ever seen

The Drag Prediction Workshop series is an extensive international effort to improve transonic aerodynamic predictions. This long-running collaborative effort seeks to mobilize the international aerospace community to improve the computational methods and tools to predict transonic aircraft performance, particularly drag.

More details on the workshop can be found at the workshop website: https://www.aiaa-dpw.org

NASA has a storied history with the workshop series from DPW-I (hosted in 2001) through the upcoming DPW-8, held in concert with Aeroelastic Prediction Workshop 4. In addition to code and methods improvements, the series also resulted in the NASA/Boeing Common Research Model (https://commonresearchmodel.larc.nasa.gov/), an open-access, commercially-relevant aircraft geometry. This geometry has been extensively tested in many facilities throughout the world and been the subject of multiple workshop series.

NASA’s contributions to the upcoming DPW-8 and subsequent work will be highlighted on this page.

Ames Science Directorate’s Stars of the Month: September 2025

The NASA Ames Science Directorate recognizes the outstanding contributions of (pictured left to right) Taejin Park, Lydia Schweitzer, and Rachel Morgan. Their commitment to the NASA mission represents the entrepreneurial spirit, technical expertise, and collaborative disposition needed to explore this world and beyond.

Earth Science Star: Taejin Park

Taejin Park is a NASA Earth eXchange (NEX) research scientist within the Biospheric Science Branch, for the Bay Area Environmental Research Institute (BAERI). As the Project Scientist for the Wildfire, Ecosystem Resilience, & Risk Assessment (WERK) project, he has exhibited exemplary leadership and teamwork leading to this multi-year study with the California Natural Resources Agency (CNRA) and California Air Resources Board (CARB) to develop tracking tools of statewide ecological condition, disturbance, and recovery efforts related to wildfires.

Space Science and Astrobiology Star: Lydia Schweitzer

Lydia Schweitzer is a research scientist within the Planetary Systems Branch for the Bay Area Environmental Research Institute (BAERI) as a member of the Neutron Spectrometer System (NSS) team with broad contributions in instrumentation, robotic rovers and lunar exploration. Lydia is recognized for her leadership on a collaborative project to design and build a complex interface unit that is crucial for NSS to communicate with the Japanese Space Agency’s Lunar Polar eXploration rover mission (LUPEX). In addition, she is recognized for her role as an instrument scientist for the Volatiles Investigating Polar Exploration Rover (VIPER) and MoonRanger missions.

Space Science and Astrobiology Star: Rachel Morgan

Rachel Morgan is an optical scientist in the Astrophysics Branch for the SETI Institute. As AstroPIC’s lead experimentalist and the driving force behind the recently commissioned photonic testbed at NASA Ames, this month she achieved a record 92 dB on-chip suppression on a single photonic-integrated chip (PIC) output channel. This advances critical coronagraph technology and is a significant milestone relevant to the Habitable Worlds Observatory.

The new finding may solve an "astrophysics mystery that has stood for nearly half a century."

Stellar mass black holes have only a few solar masses, and are much different from their gigantic counterparts, supermassive black holes. When these modestly-massive black holes are actively accreting matter, new research shows that the process is anything but orderly. Instead, it's characterized by different velocities, different ionization zones, and other complexities.

The JWST has begun examining the atmosphere of the habitable zone planet TRAPPIST-1 e. It's not finished yet, but the first observations indicate that the the planet hasn't retained its primary, or original, atmosphere. The TRAPPIST-1 star exhibits powerful flaring that likely stripped it away.

Fomalhaut is one of the brightest stars in the night sky and has been observed in great detail for decades. Some research suggests it hosts exoplanets, while other research counters that. The latest observations of the star's disk with ALMA favour the existence of a planet.

Circumstellar discs are believed to be key components in planetary formation. However, we have very little actual evidence of planets growing in the “rings” that surround young stars. So planet formation theorists were ecstatic to learn that two new papers in Astrophysical Journal Letters describe a planet that is actively forming in the gap it most likely created in the ring system of a young, Sun-like star.
