Japan's #Subaru Strategic Program has discovered a super-Earth four times the mass of our planet orbiting a red dwarf just 37 lightyears away.
The good news? This #exoplanet, named Ross 508b, might be habitable!

This super-Earth is a rocky world, on which a year is equal to just 11 Earth days.
The short orbit is down to the red dwarfs being a lot smaller than the Sun that centres our solar system. But the smaller sizes also make their gravitational fields less expansive than the Sun's.

Therefore, Ross 508b revolves around its red dwarf at a distance of just 5 million km. Mercury, in comparison, is about 60 million km from the Sun.
The short distance between this super-Earth & its red dwarf begs the question: how could it possibly be habitable?

My dear #astrotwitter colleagues, may I ask for your infinite wisdom? I am compiling a list of #exoplanet literature resources for students. What are some of your favourite textbooks and review papers of the past years?
Well, let me start with some of mine:
Seager, S., Exoplanets (1st Edition). Arizona, USA. The University of Arizona Press, 2011. ISBN-13: 978-0816529452
How I learned it; A comprehensive overview of the entire field; chapters written by topic experts; but now 11 years old

Perryman, M., The Exoplanet Handbook (2nd Edition). Cambridge, UK. Cambridge University Press, 2018. ISBN-13: 978-1108419772
Similar to "Exoplanets" but with a different twist; profits from the updated 2nd Edition

This has been a great international project with the aim to compare 4 state-of-the-art 3D global climate models (GCMs) for the case of a confirmed rocky exoplanet, linking model output to simulated observations giphy.com/clips/hamlet-t…

The cosmic universe hosts millions of inhabitable celestial bodies, but some among them are so extreme that their characteristics would scare even Lucifer himself.
Among these are the planets that revolve too close to their host star. Most such planets are fiery hot worlds made up of oceans of hot molten lava.
So let's imagine we developed the ability to send future astronauts like @astrotoya as far as we want out into the Galaxy to visit #exoplanets. With all these "Earth-like" planets out there, how do we know where to send her?
In the end, if we just know the radius, mass, and position in the habitable zone, there is no difference between #Earth as it is today and #Venus. And you don't want to travel for years to then end up on inhospitable Venus.
We want #water, #oxygen, #plants, all the things needed to make a good Caipirinha, and to preferably drink it on some alien beach. But for that, we need to first answer the following question: What would #Earth look like as a faraway #exoplanet?
