It’s been revealed that the next generation of powerful Earth and space-based telescopes will have the ability to hunt distant solar systems for evidence of life on Earth-like exoplanets especially the ones known as white dwarfs.
The chemical properties of those worlds could be indicating that life exists there. In order to help future scientists make sends of what the telescopes are showing them, it’s been reported that Cornell University astronomers developed a spectral field guide for the rocky worlds.
“We show what the spectral fingerprints could be and what forthcoming space-based and large terrestrial telescopes can look out for,” said Thea Kozakis, who conducts her research at Cornell’s Carl Sagan Institute.
It’s important to note the fact that Kozakis is the lead author of “High-resolution Spectra and Biosignatures of Earth-like Planets Transiting White Dwarfs,” that has been published in Astrophysical Journal Letters.
Searching for life on exoplanets
In a few years, astronomers will have the ability to search for life on exoplanets.
“Rocky planets around white dwarfs are intriguing candidates to characterize because their hosts are not much bigger than Earth-size planets,” said Lisa Kaltenegger, director of the Carl Sagan Institute.
It’s been reported that the trick is to catch an exoplanet’s quick crossing in front of a white dwarf.
“We are hoping for and looking for that kind of transit,” Kozakis said.
Kozakis continued and said that if we observe a transit of such a kind of planet, experts can find out what is in its atmosphere, refer back to the paper, match it to spectral fingerprints and check for life signs.
