Hubble uses sunlight reflected from the moon during an eclipse to detect ozone in Earth’s atmosphere, testing methods needed to assess exoplanet atmospheres.
Researchers find evidence for an intriguing exoplanet in archived Kepler data, a “mirror-image” Earth-like world in the habitable zone of a Sun-like star.
A presumed exoplanet orbiting the star Fomalhaut now appears to have been a dissipating cloud of debris in the aftermath of a collision between two asteroids.
Astronomers have put together spectral templates of Earth at key points in its evolution to help next-generation telescopes identify similar exoplanets.
