NASA scientists made a stunning discovery that might help show that life on Earth could, in fact, have been seeded from space. But not in the way we used to think.
Comet 45P/Honda-Mrkos-Pajdušáková, named after the three astronomers from Japan, the Czech Republic and Slovakia who discovered it independently, is an old pal for the researchers. Discovered in 1948, it has been under observation every time it returned to Earth's orbit approximately every five years. But everything changed in late 2016 and early 2017, when scientists decided to study the comet's atmospheric content by looking at chemical fingerprints in the infrared part of the spectrum, according to a Phys.org report.
