EXOPLANETS

"The larger the island of knowledge, the longer the shoreline of wonder." - Ralph W. Sockman

exoplanets

+ Info

Exoplanets are defined as being planets outside our Solar system, They can be found all around our galaxy and universe, with different sizes, compositions, temperatures and many other characteristics.

“Education is our passport to the future, for tomorrow belongs only to the people who prepare for it today.” -Malcolm X

Motivation

Lack of engaging resources

Astronomical literacy is an important factor in shaping the understanding and views of life and the universe. However, there is a lack of engaging and interesting resources on that topic

Discovering

Stimulation the youth

+ Info

We've come up with the idea to develop a game that inspires and captivates It's audience with rich and scientifically accurate gameplay

During gameplay, players will have to learn and utilize gameplay mechanics based on real world phenomena. An example would be the use of Methods for Discovering Exoplanets to colonize.

Tools

Due to passage of Exoplanets "in front of" their stars, eletrocmagnetic radiation is reduced

Due to the bending of space-time generated by Exoplanets, light deviates from its original path, creating "gravitational lenses"

Relies on the variation of the eletromagnatic radiation emitted from the star due to gravitatonal pulls of Exoplanets

Impacts

Envisioning the future

+ Info

We expect our game to attract avid fans of astronomy and casual players of different demographics (mainly teenagers to young adults)

Game presentation

The game depicts planet Earth in a distant future where society collapsed and earth was left in shambles. Your goal is to explore the galaxies and encounter a suitable planet that Humans can call "Home". You will develop and grow civilizations in the hopes that someday, humans will achieve greatness once again!

Game Logistics

Our project is expected to attract a big playerbase of space fans and gamers who are intersted in sci-fi games. Through innovation and engaging gameplay, this project may be able to sell hundreds, maybe thousands of copies in a short amount of time, generating substantial profits.

In depth

Gravitational lensing

Thanks to the developments of General theory by Albert Einstein in the 20th century, a new theory of gravity was formulated. One of its consequences is the bending of light near strong gravitational fields (such as the ones in stars and planets).When incoming light gets significally stronger and then suddenly weaker, this could imply that a massive object (such as an Exoplanet) is in the path of incoming light, bending it in such a way that it can serve as lenses.

First signs of Exoplanets

The first Exoplanet was discovered only discovered in the year 1984 thanks to the observations made by the Las Campanas Observatory, In Chile.

In depht

Radial Velocity

Through the analysis of an apparent "Wobble" on distant stars(Thanks to physical phenomena such as "Doppler Shift" or "Doppler Effect") We are able to determine the presence of a significant gravitational pull in the star (possibly due to an Exoplanet) and Through this effect and others, we can determine characteristics of the Exoplanet, such as its mass.

In depth

Transit

When an massive enough object passes in front of a star (with respect to a reference frame), Satellites can detect radiation drops coming from the star. Through futher observations of the data, we can determine characteristic of such object (such as its radius and volume) which helps us discover the presence of Exoplanets in the system.

• Transits are similar to Solar eclipses that we can see from time to time here on earth
