Tidal Forces and Orbital Evolution of Habitable Zone Planets

Universe Today - Sat, 08/23/2025 - 11:29pm

How do tidal forces determine a planet’s orbital evolution, specifically planets in the habitable zone? This is what a recently submitted study hopes to address as an international team of researchers investigated how tidal forces far more powerful than experienced on Earth could influence orbital evolution of habitable zone planets with highly eccentric orbits around low-mass stars. This study has the potential to help researchers better understand the formation and evolution of exoplanets, specifically regarding where we could find life beyond Earth.

Moon Flybys Could Save Fuel On Interplanetary Missions

Universe Today - Fri, 08/22/2025 - 3:13pm

The Three Body Problem isn’t just the name of a viral Netflix series or a Hugo Award winning sci-fi book. It also represents a really problem in astrodynamics - and one that can cause headaches to mission planners in terms of its complexity, but also one that offers the promise of an easier way to enter stable orbits that might otherwise be possible. A new paper from researchers at the Beijing Institute of Technology shows one way those orbital maneuvers might be enhanced while exploring planetary systems - by using a gravity assist from its moons.

A 3D Printed Alumnium Mirror Could Enable Enhance CubeSat Observations

Universe Today - Fri, 08/22/2025 - 3:13pm

Compact, reflective, easy to manufacture mirrors are a critical component for advancing astronomical technology in space. Mirrors are a key component in most telescopes, though they are notoriously hard to manufacture with the necessary precision, especially at large scales. A new paper from researchers in the UK uses additive manufacturing to make a thin, flexible, and lightweight mirror out of aluminum and analyzes its properties to see if it will be useful in applications such as CubeSats.

Tracking the Interstellar Objects 1I/'Oumuamua, 2I/Borisov, and 3I/Atlas to their Source

Universe Today - Fri, 08/22/2025 - 3:13pm

In a recent paper, researchers followed the trajectories of 1I/`Oumuamua, 2I/Borisov, and 3I/ATLAS - three installer objects that have entered the Solar System in the past decade - to constrain their possible origin. Through a series of Monte Carlo simulations, they came up with predictions of where they came from and how old they are.
