Dr. Mia Mace’s scientific research interests lie in numerical modeling of planetary ring systems, and her doctoral work focused on developing code to simulate and analyze the dynamics of charged dust grains in Saturn’s rings in response to questions about ring rain and spokes.

Earth-sized #exoplanets must possess at least 20% to 50% of the water volume found in Earth's oceans to maintain the critical natural climate cycles required to sustain surface water and support life. Planets with limited surface water—often classified as desert worlds—are highly unlikely to remain habitable, regardless of their position within a star's habitable zone.

Planets need more water to support life than scientists previously thought

Water, although essential, does not guarantee the existence of life.

#PPOD: The #ArtemisII crew captured this view of Earth setting on April 6, 2026. As the astronauts flew over the Moon’s far side, the crew photographed and described terrain features, including impact craters, ancient lava flows, and surface cracks and ridges formed as the Moon slowly evolved. They also noted differences in color, brightness, and texture, which provide clues that help scientists understand the composition and history of the lunar surface. Credit: NASA

The details of this vent, obtained by HiRISE, should provide insight into volcano-tectonic processes along the Cerberus Fossae fissures in two ways. Credit: NASA/JPL-Caltech/Univ. of Arizona

Meteorite Contamination Raises Questions About Sample Integrity

New research found ink and diamond dust on Mars rocks. This could change how scientists study space samples from future missions.

Scientists found tiny pieces of ink and diamond dust on Mars rocks. This is like finding a tiny crumb on a very important document, making it harder to read the real story.

How the Artemis program is inspiring this aspiring astroscientist in Stittsville
Lucy Hambly, 17, is a space columnist for the website Stittsville Central and will study planetary science at the University of Toronto in the fall. She tells CBC's Rachelle Elsiufi what the Artemis II mission has meant for her aspirations.

Recent laboratory findings reveal that Mercury's magmas stay molten at significantly lower temperatures than Earth's due to the planet's unique chemical composition, which is highly reduced, iron-poor, and sulfur-rich.

Sulfur reshapes interior evolution and crust formation on Mercury

Rice researchers find sulfur-rich Mercury magmas behave differently than Earth’s

I seem to be in a bit of a #space mood 🪐🔭 at the moment 😅, so I remembered that I once visited the #Smithsonian National Air and Space Museum in Washington, DC and wrote a short blog post about it. I thought I would share it again here:

Pretty much a solid day studying. A week ahead, and started prepping my next assessment, though I still have a practical to do.

I have enjoyed the last two topics a LOT, especially astrobiology and planetary science. I was getting really carried away looking through open source exoplanet data to find potentially habitable planets in distant star systems. Enough that I looked into maybe switching pathways, but the maths remains too intimidating.
