How Yavin IV and Orbital Mechanics Destroyed the Death Star

Mia Bovill, Texas Christian University

At the end of “Star Wars: Episode IV,” the Death Star orbits the moon Yavin IV while seeking to target the rebel base on its surface. This maneuver takes long enough that Luke Skywalker is able to destroy the celestial juggernaut in the nick of time. Was this delay scientifically reasonable? The answer lies in the basic tenets of orbital mechanics.

In addition, given the wealth of observational data on exoplanetary systems from telescopes like NASA’s Kepler Mission, one can address many other questions about this scenario. Is it possible to have a gas giant planet orbited by a planet-sized moon that has dense vegetation and a breathable atmosphere? How massive would Yavin IV be and what is its likely composition? Dr. Bovill explains how astrophysics is the force that offers a new hope in comprehending this encounter with the dark side of a moon.

How the Roman Space Telescope Will Study Galaxies

NASA’s Nancy Grace Roman Space Telescope will be a powerful tool for studying galaxies throughout the cosmos. It will be able to provide spectra for every galaxy in its field of view. And with a field of view 200 times that of the Hubble Space Telescope at infrared wavelengths, Roman can capture thousands of objects of interest in a single observation.

Understanding the Formation and Evolution of Galaxies

Cameron Hummels, Caltech

Galaxies—like our own Milky Way—are among the basic building blocks of our universe. Discovered only one hundred years ago, galaxies are complex systems consisting of billions of stars, along with gas, dust, and dark matter. They occupy much of what we see when we gaze at the night sky through our telescopes.

Astronomers learn about galaxies using both telescope observations and sophisticated computer simulations. These numerical investigations are crucial in helping us better understand how galaxies form and evolve since the birth of our universe.

Eta Carinae and the Homunculus Nebula in 3D

Frank Summers, Space Telescope Science Institute

Eta Carinae is the closest, best known, and most studied of the stars known as “supernova impostors”. After surviving a supernova-like brightening in the 1840’s, Eta Car faded away for the rest of the 19th century, and slowly grew more luminous over the 20th century. Modern observations across visible, ultraviolet, and x-ray wavelengths reveal complex, nested structures of gas and dust that resulted from the 1840’s Great Eruption and other outbursts from this massive star system. Dr. Summers will showcase a 3D visualization of these nebulae as well as delve into the colliding wind binary star at the core of this remarkable celestial object.

No Man’s Sky: A Simulation Inside a Simulation?

No Man’s Sky is … gigantic. Players traverse an entire, simulated universe exploring procedurally generated planets; there is practically no limit to what you can see. No Man Sky’s creator Sean Murray estimates that players will see maybe 1% of what the game is capable of generating. On top of that, much of the appearance and behavior of things in that universe–planets, plants, creatures, light itself–is emergent. The creators didn’t decide how stuff looks or behaves on a planet by planet basis. They made systems and rules that generate stuff and decide what happens when various stuffs mingle. Appearances and outcomes aren’t designed; they emerge. No Man’s Sky is lush and naturalistic. It’s detailed and even occasionally… life like. So this begs the question: if we’re able to simulate a universes of massive, life-like complexity–like that of No Man’s Sky–within our universe… should we wonder, or worry, that our own massive… life-like universe is itself… simulated? Today on Idea Channel we discuss No Man Sky and the Simulation Argument! Let us know what you think in the comments below!
