With her Early Career Research Award, Stanford University associate professor Sigrid Elschot studied the effects of fast-moving, microgram-sized particles that collide with spacecraft. These particles vaporize, ionize, and produce a plasma that radiates electromagnetic energy.
The Earth Dynamics Geodetic Explorer (EDGE)—a newly proposed NASA satellite mission to monitor the three-dimensional structure of global vegetation and ice—is one of four finalists selected for NASA’s next generation of Earth-observing satellites under the Earth System Explorers Program.
More than 70 NOIRLab staff volunteers welcomed hundreds of visitors from the Tohono O’odham Nation to Kitt Peak National Observatory to enjoy a night of telescope viewings, cultural performances, and educational activities.

A cutting-edge method for Global Navigation Satellite System (GNSS) ambiguity resolution has been developed, promising to enhance the accuracy and reliability of urban positioning. This innovative approach addresses the longstanding challenge of obtaining precise location data in built-up environments where signals are often obstructed.
Exoplanets are planets beyond our solar system. To date, more than 5,000 of them have been identified. They are expected to form and orbit around stars, in a similar fashion to planets in our solar system. However, some appear “free-floating” in space, not bound to any host star. The puzzle to their formation was further deepened in fall 2023, when astrophysicists using the James Webb Space Telescope identified massive floating binary objects about the size of Jupiter – and dubbed them JuMBOs (Jupiter-mass binary objects).
Astronomers are now using AI to measure the expansion of our universe. Two recent studies led by Maria Dainotti, a visiting professor with UNLV’s Nevada Center for Astrophysics and assistant professor at the National Astronomical Observatory of Japan (NAOJ), incorporated multiple machine learning models to add a new level of precision to distance measurements for gamma-ray bursts (GRBs) – the most luminous and violent explosions in the universe.
A team in Denmark examining archival data from the James Webb Space Telescope recently found a trio of distant galaxies that are in the process of gathering gas when the universe was only a few hundred million years old. Their detection and characterization are remarkable achievements that only Webb is currently capable of, thanks to its specialization in infrared light.
Another exciting milestone in the construction of Rubin Observatory has been achieved! On May 16th Rubin’s LSST Camera reached its forever home, the summit facility on Cerro Pachón.

An ocean of liquid water deep beneath the icy surface of Pluto is coming into focus thanks to new calculations by Alex Nguyen, a graduate student in earth, environmental and planetary sciences in Arts & Sciences at Washington University in St. Louis.
A global team of researchers set a new benchmark for future experiments making materials in space rather than for space. The team discovered that many kinds of glass, including ones that could be developed for next-generation optical devices, have similar atomic structure and arrangements and can successfully be made in space.
Why is the warm gas-giant exoplanet WASP-107 b so, so puffy? With a moderate temperature and an ultra-low density on par with a microwaved marshmallow, it seems to defy standard theories of planet formation and evolution. Two independent teams of researchers think they’ve figured it out.
China's Earth Observation (EO) System has seen significant progress, evolving into a sophisticated network of satellites supporting various global applications. This system, vital for sustainable development, promises further advancements with new technologies enhancing its capabilities.
Researchers have significantly improved the accuracy of global geodetic parameters by employing Satellite Laser Ranging (SLR) to a wider array of Global Navigation Satellite System (GNSS), satellites, according to a recent study. This advancement aids crucial applications in geosciences and satellite navigation.
STScI assistant astronomer John Wu has been named 2024 Outstanding Young Scientist by the Maryland Academy of Sciences. Using machine-learning methods that he developed, he has pioneered the discovery of low-mass galaxy candidates and contributed to theoretical models of galaxies, dark matter halos, and their cosmic surroundings.
Ochoa received the honor for her contributions to space exploration and inspiring future generations.
The GRATTIS mission from the University of Florida was selected this week by NASA, which includes sensor technology that will provide vital insights into movement of water and ice across the planet.
The universe’s earliest stars, known as Population III stars, are notoriously hard to detect with even our most powerful observatories due to their great distance and short lifetime.
