Nice pun! An exoplanet is any planet that is outside our solar system - it doesn't necessarily have to be Earth-like. Observations of exoplanets aren't quite like what most people imagine when they think of a photograph of a planet. Our current generation of telescopes aren't powerful enough to directly look at exoplanets and get useful information about their physical characteristics. Instead, astronomers use other clever tricks to learn about these mysterious celestial objects. 

We can determine the mass of exoplanets by analyzing the slight wobble of its parent star caused by the tiny gravitational tug by the exoplanet. The larger the mass of the exoplanet, the greater the gravitational tug and wobble of the parent star. We can tell if an exoplanet has an atmosphere and what its composition is by watching as the exoplanet moves in between the star and our telescopes. This is called **transit spectroscopy**. When the exoplanet moves in front of the star, the light from the star is blocked, and it gets slightly dimmer from our perspective. When can tell what the atmosphere is made of because certain molecules absorb specific wavelengths of light. We can think of this as something like a unique chemical fingerprint for the atmosphere.

Through careful and precise observations, we can tell the mass of exoplanets by looking at how much they affect their parent star's orbit, and we can also figure out what's in the atmosphere by measuring the wavelengths of light that get absorbed. Humanity's next generation of powerful telescopes are currently being built, and when they become operational, new frontiers of discovery will be waiting for us!
