In the search for life on other planets, a couple of promising leads have just opened up: Astronomers have identified two worlds with Earth-like masses, sitting in the habitable zone around a red dwarf star called GJ 1002.
That's because the faint light coming off GJ 1002 required instruments of great sensitivity and precision to recognize its signatures. The research team used 139 spectroscopic observations taken between 2017 and 2021 to spot the planets.
So far, we don't know much about these celestial bodies, except where they're located. GJ 1002b is closest to its star and takes just over 10 days to complete an orbit; GJ 1002c is further out, with an orbit of just over 20 days. The good news is that the relatively close proximity of GJ 1002b and GJ 1002c means that more detailed observations are easier to do. The next step will be to assess their atmospheres based on either the light they reflect or the heat they give off.
"The future ANDES spectrograph for the ELT telescope at ESO, in which the IAC is participating, could study the presence of oxygen in the atmosphere of GJ 1002c,"We're now up to a total of 5,000 exoplanets – planets outside our Earth – that have been observed. As telescopes and data-crunching algorithms get better, we can spot objects that are smaller and further away from Earth.on these distant planets, even though they're light-years away through space.from IAC.
