University of Warwick astronomers have uncovered the chemical fingerprint of a frozen, water-rich planetary fragment being consumed by a white dwarf star outside our solar system.
In our nearby stellar neighborhood, a burned-out star is snacking on a fragment of a Pluto-like object. With its unique ultraviolet capability, only NASA's Hubble Space Telescope could identify that this meal is taking place.
A Southwest Research Institute-led team has reported the first detection of gas on the distant dwarf planet Makemake, using NASA's James Webb Space Telescope (JWST). This discovery makes Makemake only the second trans-Neptunian ...
You know, if you think about it, and trust me we're about to, the moon is kind of weird. Of all the terrestrial worlds of the solar system, we're the only one with a substantial natural satellite. Mercury and Venus have nothing. ...
Since 2017, three interstellar objects have been spotted passing through our solar system: 1I/ʻOumuamua, 2I/Borisov… and just this month, 3I/ATLAS. Discovered on July 1 by the Asteroid Terrestrial-Impact Last Alert Survey, ...
Is there a massive undiscovered planet on the outer reaches of the solar system? The idea has been around since before the discovery of Pluto in the 1930s. Labeled as planet X, prominent astronomers had put it forward as ...
Southwest Research Institute (SwRI) scientists conducted lab experiments to address a mystery about the origins of frozen hydrogen peroxide (H2O2) on Jupiter's icy moon Europa. Their results, published in the July 2025 issue ...
Trans-Neptunian objects (TNO) are some of our solar system's lesser-known objects. They number in the thousands, and they get their name from their orbits. These dwarf planets orbit the sun at a greater average distance than ...
The Subaru Telescope has made an exciting discovery: a small body beyond Pluto, with implications for the formation, evolution, and current structure of the outer solar system.
Our two-person team loaded the car with a GPS, a drone, notebooks, sample bags, a trowel and a flat spatula lovingly called a scoopula. Then we drove 30 minutes in our rented truck from Yuma, Arizona, to the Algodones Dunes, ...
