Have you ever looked up at the night sky and wondered if we are alone in the universe?Simon Schuler, assistant professor of physics, doesn’t think we are the only ones in this world. He said the first step in answering this universal question is to find planets like Earth that are in the “habitable zone” of a star, where the temperature is not too hot or too cold and liquid water can exist. One of Schuler’s current research projects may help scientists find these planets more quickly. “We have to start with what we know,” said Schuler.NASA’s most recent effort to identify planets outside our solar system, or exoplanets, is the Kepler Mission, which launched a specially designed space telescope to find habitable planets in other parts of our galaxy.

To date, Kepler has identified more than 3,500 possible planets outside our solar system (from 2009–2013).Schuler explained that the Kepler instrument only looks in one direction.“So just in this one small part of our galaxy, there are thousands of planets,” said Schuler, implying that there are likely millions more in other parts of our galaxy.Schuler currently holds a grant from NASA to study the chemical compositions of stars hosting planets discovered by Kepler. He is looking for differences in the compositions of stars with planets and those not known to have planets to identify possible signatures of the planet formation process.The purpose of this is to discover if there is a particular composition, a chemical signature, that determines the kind of planets that form.

Have you ever looked up at the night sky and wondered if we are alone in the universe?
Simon Schuler, assistant professor of physics, doesn’t think we are the only ones in this world.

Kepler finds planets by looking for tiny dips in the brightness of a star when a planet crosses in front of it, called the transit method. To date, Kepler has identified more than 3,500 possible planets outside our solar system (from 2009–2013).
Schuler explained that the Kepler instrument only looks in one direction.
“So just in this one small part of our galaxy, there are thousands of planets,” said Schuler, implying that there are likely millions more in other parts of our galaxy.
Schuler currently holds a grant from NASA to study the chemical compositions of stars hosting planets discovered by Kepler. He is looking for differences in the compositions of stars with planets and those not known to have planets to identify possible signatures of the planet formation process.
The purpose of this is to discover if there is a particular composition, a chemical signature, that determines the kind of planets that form. If this chemical signature exists, when you look out at the universe and find a star with that chemical signature, it should have Earth-sized planets.
That is a big “if,” but if scientists can identify such a signature, it could save time and millions of dollars.
“Kepler was a $600 million piece of equipment we sent out to find these types of planets,” said Schuler. “If we have a signature that we can look for, at the very least it can help give us some direction of which way to point the next one.”
