A wave of recent developments in planetary science is capturing the attention of researchers across the United States and the world. According to the July 2025 Space News Digest, the Vera Rubin Observatory in Chile, funded in part by the National Science Foundation in the United States, has officially embarked on its decade-long Legacy Survey of Space and Time. This observatory utilizes the most sophisticated 3.2 gigapixel camera ever built to capture the southern sky every few days. Within its first full week of operations, it has already revealed millions of distant galaxies and more than two thousand new asteroids. The goal over the next ten years is to catalog more than forty billion cosmic objects, including stars and asteroids, offering fresh insights into the structure of our Milky Way and the broader universe. The observatory’s data is open-access, which is expected to accelerate global collaboration and innovative discoveries by researchers both in the United States and internationally. Scientists are particularly excited by its potential to enable time-domain astronomy at an unprecedented scale, allowing for the tracking of transient events and improving our understanding of dark matter and dark energy.

Meanwhile, NASA’s Lucy spacecraft continues its journey through the main asteroid belt. NASA reports that the Lucy mission has just completed a successful flyby of the asteroid Donaldjohanson in April, gathering images and data that the team is now analyzing. This event served as a dress rehearsal for Lucy’s main encounters with the Jupiter Trojan asteroids, which are set to begin in August 2027 with a flyby of the asteroid Eurybates. The mission aims to observe a group of these ancient objects, some accompanied by their own small satellites, to help scientists understand the origins of our solar system. The Lucy spacecraft is currently in a quiet cruise phase, traveling away from the Sun at more than thirty thousand miles per hour as it prepares for these landmark encounters.

In the realm of planetary observation from Earth, the U S National Oceanic and Atmospheric Administration’s Space Weather Prediction Center forecasts an unusually widespread display of the northern lights this week. A coronal mass ejection from the Sun is causing a geomagnetic storm, making the aurora borealis visible in as many as fourteen U S states, including Wisconsin and Oregon. This phenomenon not only provides a stunning natural spectacle for observers but also serves as an opportunity for atmospheric and planetary scientists to monitor solar activity and its effects on Earth’s magnetosphere.

These highlights reflect an emerging pattern of increasingly powerful observational tools, global cooperation, and sophisticated missions. They are pushing the boundaries of what is possible in planetary science and are generating a wealth of data that will shape our understanding of both our solar system and the broader universe in the years ahead.
