Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people

Using HIFI to “Sniff” Enceladus’ Plumes

Universe Today - 17 hours 27 min ago

What kinds of scientific instruments can be used to sample the plumes of Enceladus with the goal of identifying the ingredients for life as we know it? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of international researchers investigated how the novel High Ice Flux Instrument (HIFI) could be the next-generation instrument used to sample the plumes of Enceladus while building off the groundbreaking findings from the NASA Cassini spacecraft’s Cosmic Dust Analyzer (CDA). This study has the potential to help scientists and engineers develop new and efficient methodologies for finding life on Enceladus and throughout the solar system.

Uranus’ Moons Could Have Cryovolcanism from Potential Interior Oceans

Universe Today - Sun, 03/30/2025 - 7:21pm

What can cryovolcanism on the dwarf planet Ceres teach us about potential cryovolcanism on Uranus’ five largest moons, which include Oberon, Umbriel, Ariel, Titania, and Miranda? This is what two studies recently presented at the 56th Lunar and Planetary Science Conference hopes to address, as a team of researchers investigated using Ceres as an analog for the potential ocean moons, Umbriel and Oberon, and the likelihood of an impact crater on Umbriel showing evidence of cryovolcanism. These studies have the potential to help researchers better understand the formation and evolution of ocean worlds in the outer solar system and whether they could potentially have life as we know it.

Many Protoplanetary Disks Aren't Much Bigger Than Earth's Orbit

Universe Today - Sun, 03/30/2025 - 3:47pm

When it comes to the planets produced in protoplanetary disks, size matters, but not the way you might think. That's the conclusion a group of astronomers found when they aimed the Atacama Large Millimeter Array in Chile at hundreds of these disks around young stars in the southern constellation Lupus. They used the observatory in 2023 and 2024 to focus on the disks and supplemented that with archival data.
