Dynamics of Ocean Worlds Likely Controlled by Their Rotation

by Morgan Rehnberg 9 May 202227 July 2022

New simulations suggest that subsurface oceans on icy moons with small natural Rossby numbers may be dominated by rotational effects.

Encontrando los océanos ocultos de las lunas usando campos magnéticos inducidos

by Morgan Rehnberg 5 May 20225 May 2022

Un análisis de componentes principales de modelos especulativos puede predecir con más seguridad que las técnicas anteriores la p^ppresencia de un océano subsuperficial en un objeto planetario.

Finding Moons’ Hidden Oceans with Induced Magnetic Fields

by Morgan Rehnberg 9 March 20225 May 2022

A principal component analysis of speculative models can more confidently predict the presence of a planetary object’s subsurface ocean than previous techniques.

Tidally Locked and Loaded with Questions

by Caroline Hasler 17 February 202217 February 2022

Tidally locked planets always present the same face to their host stars. What does this mean for their potential to support life?

A rocky planet and a smaller rocky moon sit on a black background with dark red streaks. The planet in the foreground has a cratered surface and has patches of red, green, gray, and blue rocks. The smaller grayish brown rocky moon in the background is between 10 and 11 o’clock relative to the planet.

To Make a Big Moon, Start with a Small Planet

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 10 February 202210 February 2022

Why is our Moon so massive compared with Earth, and how might that configuration happen elsewhere?

A hemisphere of the moon Europa sits on a black background, with the curve of the horizon toward the top of the image. The moon’s surface is a light gray-brown and is crisscrossed with dark brown streaks and splotches.

Europa’s Ocean Can Tug Its Ice Shell Around

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 13 January 202213 January 2022

Sometimes ocean dynamics are a drag.

A bright orange ring of dust surrounds a fuzzy orange center that hides the central star of the PDS 70 system. Sitting between the central star and the planet-forming dust disk is a small, bright orange dot that is the young planet PDS 70 c.

Where Moons Are Made

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 4 August 202126 April 2022

The young, growing planet PDS 70 c has enough material swirling around it to make at least three Moon-sized moons.

A Window into the Weather on Titan

Kate Wheeling, freelance science writer by Kate Wheeling 22 March 20218 March 2022

Cassini’s final flybys of Saturn’s largest moon may have captured a temperature drop due to rainfall, one of the first observations of weather changes on Titan.

Do Uranus’s Moons Have Subsurface Oceans?

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 14 December 20203 November 2021

Scientists tested whether a classic technique could detect subsurface oceans on the moons of Uranus. In this scenario, the planet’s oddball magnetic field offers a big advantage.
