 ## Space molecules 🧪 ⚗️ in your terminal 💻 !
 
+<div align="justify">

 Outer space is cold 🥶 and vast. Since molecules often need to collide with one another with sufficient energy to form and react, scientists assumed that there could never be any molecules in space. Space was just too cold and too big for two molecules to ever encounter one another with enough energy. And then radio astronomers 📡 detected some of the first molecules in space. A realisation hit the astronomical community at large; whatever they thought they knew about chemistry in space was wrong. Thus began a completely new field: ✨ **astrochemistry** ✨. Since then, we have discovered all kinds of molecules in space: from smelly *ammonia* 🤢 to intoxicating *ethanol*, 🍻. To date, we know of more than *200 molecules* 🤯 that our telescopes have detected in space, and the number increases each year.

 Excited 😁? Check out the [**docs**][docs] for more info on how to install and use spacetar, both from within Python and from the command line. If you find this project fun, star ⭐ the [**repo**][repo] on GitHub! You can also rave about spacetar, or bring up your ideas 💡 / feature requests, in the [**discussions**][discuss] or via [**email**][me-email]. You can also make an [**issue**][issues] if run into a bug 🐛.
 
 [**spacetar**][repo], like everything else, stands on the *shoulders of giants*. It uses data compiled by [*Prof. Brett McGuire*][brett-github] for his paper 📝, the [*2018 Census of Interstellar, Circumstellar, Extragalactic, Protoplanetary Disk, and Exoplanetary Molecules*][census-paper]. You can find the database, along with some of the code that inspired [**spacetar**][repo] in the first place, in the associated [*GitHub repository*][census-repo]. Thank you Brett for the wonderful work 😄 ! If you end up using the database in [**spacetar**][repo] for something that might lead to a scientific publication, don't forget to cite the associated paper above 👍.
