Hubble ExoPlanet Research
The Hubble Telescope has measured the size of our nearest Earth-sized exoplanet. The planet orbits the star LTT 1445A, which is part of a triple system of three red dwarf stars that is 22 light-years away in the constellation Eridanus.

Exoplanets Transit simulator
This was posted to Mastodon by Dr. Alexandre Santerne. Just had a go and it looks really nice and smooth, and has few options to change the simulation parameters.
Do you know how #astronomers are hunting for #exoplanets ? Most of them are discovered with the transit and/or radial velocity techniques.
We developed at #LAM (#laboratoire d'#astrophysique de #Marseille) a web tool that simulate an #exoplanet and show you their photometric and radial velocity signals. Feel free to play with the parameters and see how they change the signals.

Exoplanet Watch
NASA are looking for help from citizen scientists to find exoplanets. This was posted to fedi, so am sharing here to help with reach and hopefully find people to take part.

First stars
We are making discoveries so fast, it is hard to keep up. We are learning more and more about the origin of the universe each time. These first stars are probably long gone, but the light the produced is still moving.
