Traces of Carbon Dioxide Found in Exoplanetary Atmosphere

Traces of carbon dioxide, one of the building blocks of life, has been found on a planet orbiting another star. Even though it orbits its parent star in 2.2 days, and it is too hot for life, it is still an exciting discovery. Previous observations of this planet have shown traces of water vapor and methane in its atmosphere. This discovery was made using the Hubble Space telescope and the Spitzer space telescope. Also, this is the first time a near-infrared emission spectrum has been used to see an exoplanet.
