Identifying a mineral might sound straightforward: analyze its chemistry, compare it to known minerals and voilà. But for geologists, this process can be a time-consuming puzzle requiring specialized expertise and a lot of manual calculation. Now, a team of researchers at Rice University’s Department of Earth, Environmental and Planetary Sciences has developed MIST — Mineral Identification by Stoichiometry — the first online tool capable of automatically identifying hundreds of different mineral species from their chemical composition using a carefully designed rules-based algorithm.

For the first time, astrophysicists detected a supernova embedded in a wind rich with silicon, sulfur and argon. Observations suggest the massive star lost its outer hydrogen and helium layers long before exploding. Discovery offers direct evidence of the long-theorized inner shell structure of massive stars.

A newly published paper, led by IPAC scientist Joe Masiero, provides evidence that two kinds of asteroids likely formed in the same regions during the beginning of our solar system. “Asteroids offer us the chance to look at what was going on in the early solar system like a freeze frame of the conditions that existed when the first solid objects formed,” said Masiero.

Astronomers from Chalmers University of Technology, Sweden, have discovered a vast and expanding bubble of gas and dust surrounding a red supergiant star – the largest structure of its kind ever seen in the Milky Way. The bubble, which contains as much mass as the Sun, was blown out in a mysterious stellar eruption around 4000 years ago. Why the star survived such a powerful event is a puzzle, the scientists say.

The new results are published in the scientific journal Astronomy and Astrophysics, and the team was led by Mark Siebert, Chalmers, Sweden. Using the ALMA radio telescope in Chile, the researchers observed the star DFK 52 – a red supergiant similar to the well-known star Betelgeuse.

Using XRISM, JAXA’s new high-precision X-ray spectroscopic satellite, researchers observed a stellar-mass black hole in the Milky Way and detected highly ionized iron absorption lines — clear signatures of hot gas. Remarkably, this detection was achieved at the dimmest X-ray state ever reported for such a system. The results reveal the complex structure and motion of gas around the black hole, offering new insights into the dynamic behavior of black holes.

SAN ANTONIO — August 19, 2025 — Southwest Research Institute led a James Webb Space Telescope (JWST) survey, discovering a previously unknown tiny moon orbiting Uranus. A team led by SwRI’s Dr. Maryame El Moutamid discovered the small object in a series of images taken on Feb. 2, 2025, bringing Uranus’ total moon count to 29.
