This is because different elements and molecules absorb light at characteristic energies; and this is how we know where in a spectrum we might expect to see the signature of sodium (or methane or water) if it is present. The 2023 phase and libration of the Moon at hourly intervals. He is also interested in evolution, climate change, robots, space exploration, environmental conservation and anything that's been fossilized. We may be one step closer to understanding the unknown parts of our universe. We don't know when, or even if, we'll find life beyond Earth, but NASA scientists continue the hunt among the thousands of exoplanets confirmed in the galaxy so far. Or is it incredibly rare? Even organics that are present only in trace amounts have signatures at infrared wavelengths that Webb will be able to detect due to the observatory's superb spectrometric sensitivities and high spatial resolutions. A year on this planet, in other words, lasts only four days. If, for example, the planet has sodium in its atmosphere, the spectrum of the star, added to that of the planet, will have what we call an "absorption line" in the place in the spectra where would expect to see sodium (see graphic below). Learn about Jupiter's icy moon and NASA'sEuropa Clipper mission. Pat Brennan NASA is exploring the solar system and beyond to help us answer fundamental questions about life beyond our home planet.
