For some people, a passion for space is something that might develop over time, but for Patrick Junen, the desire was there from the beginning. With a father and grandfather who both worked for NASA, space exploration is not just a dream; it remains a family legacy. Now, as the stage assembly and structures subsystem […]

The Andromeda galaxy, also known as Messier 31 (M31), is a glittering beacon in this image released on June 25, 2025, in tribute to the groundbreaking legacy of astronomer Dr. Vera Rubin, whose observations transformed our understanding of the universe. In the 1960s, Rubin and her colleagues studied M31 and determined that there was some unseen […]
Present-day disk galaxies often contain a thick, star-filled outer disk and an embedded thin disk of stars. For instance, our own Milky Way galaxy’s thick disk is approximately 3,000 light-years in height, and its thin disk is roughly 1,000 light-years thick. How and why does this dual disk structure form? By analyzing archival data from […]
In autumn 2024, California’s Monterey Bay experienced an outsized phytoplankton bloom that attracted fish, dolphins, whales, seabirds, and – for a few weeks in October – scientists. A team from NASA’s Ames Research Center in Silicon Valley, with partners at the University of California, Santa Cruz (UCSC), and the Naval Postgraduate School, spent two weeks […]
The Mars Reconnaissance Orbiter is testing a series of large spacecraft rolls that will help it hunt for water. After nearly 20 years of operations, NASA’s Mars Reconnaissance Orbiter (MRO) is on a roll, performing a new maneuver to squeeze even more science out of the busy spacecraft as it circles the Red Planet. Engineers […]
When two stars orbit one another in such a way that one blocks the other’s light each time it swings around, that’s an eclipsing binary. A new paper from NASA’s Eclipsing Binary Patrol citizen science project presents more than 10,000 of these rare pairs – 10,001 to be precise. These objects will help future researchers study […]

The Andromeda galaxy, also known as Messier 31 (M31), is the closest spiral galaxy to the Milky Way at a distance of about 2.5 million light-years. Astronomers use Andromeda to understand the structure and evolution of our own spiral, which is much harder to do since Earth is embedded inside the Milky Way. The galaxy […]

What are asteroids? Asteroids are rocky objects that orbit the Sun just like planets do. In fact, sometimes asteroids are called “minor planets.” These space rocks were left behind after our solar system formed about 4.6 billion years ago. Asteroids are found in a wide range of sizes. For example, one small asteroid, 2015 TC25, […]
