Astronomers discover two potentially habitable exo-Earths around a star near the sun

Scientists from the Instituto de Astrofisica de Canarias (IAC) and its worldwide collaborators have discovered two Earth-sized planets around the red dwarf star GJ 1002. Both planets are located in the star's habitable zone.

According to the study's authors, these two discoveries bring the total number of nearby planetary systems discovered to seven.

The newly found planets are in orbit around the star GJ 1002, which is located fewer than 16 light years from our own sun.

Both of them are in the star's habitable zone and have masses comparable to Earth's.

The inner planet, GJ 1002b, orbits the star in a little over 10 days, whereas GJ 1002c takes a little over 21 days.

In terms of stellar mass, GJ 1002 is a red dwarf, with only around one-eighth that of the Sun. It is quite a cool, faint star r. This indicates that the planet's habitable zone is quite near to its star.

The two planets, particularly GJ 1002c, are great prospects for the characterisation of their atmospheres based on either their reflected light or their thermal emission because to their close closeness to the star.

The discovery was achieved thanks to a joint effort by the ESPRESSO and CARMENES instrument collaborations.
CARMENES spotted GJ 1002 between 2017 and 2019, and ESPRESSO will see it again between 2019 and 2021.

The researchers reported that the visible light from GJ 1002 is too weak for most spectrographs to assess its velocity fluctuations because of its low temperature.

By using the 3.5m telescope at the Calar Alto observatory and the CARMENES spectrograph, they were able to see GJ 1002 and its velocity fluctuations over the near infrared spectrum. This is an improvement above previous spectrographs designed to detect such changes.

The combination of ESPRESSO and the light collecting capability of ESO's VLT 8m telescopes enabled measurements to be done with an accuracy of barely 30 cm/sec, which no other instrument on the planet could match.

"GJ 100b" Aliens. 'Keep out Humans!' And don't invade our nearest planet, too. We claimed it for our empire. You're not welcome here!'

It is supposed to be true: it can be checked in Anton Petrov's channel, he posted a video about it 12 hours before this one. Anton is considered a reliable source in YT and he usually support his videos with scientific papers... however the Anton's video about this subject has none - I suppose he got this one directly from the observatories and labs as fresh news.

So.... can we get a picture of them with the JWST?

Ok let's get the new fusion drive online and go there.... :)

It's obviously the home (or one of the homes) of The Greys, since they, reportedly anyway, are capable of operating at the earth's surface without any external protection. Add to that the "fact" that The Greys are typically taller and thinner than their human counterparts, which is an expected result of evolution on a planet that is slightly more massive than the earth.
