Only eight planets remain in the #ExoCup2020! - which one of these will make it into the final four?
#Proximab - An earth-mass planet around an M-dwarf and our nearest neighbour!
#WD1856b - The first ever planet found transiting a white dwarf (an earth-sized stellar remnant).
GO!
This is also the first ever #ExoCup match where both planets have twitter representation, so I'm sure @WD1856_534b & @Proximab16 will be vying for your votes. For some less-biased stats, there's always our fact cards. And as always, share your own opinions using #ExoCup2020.pic.twitter.com/waha1cJdpL
Good luck and may the best exoplanet win.
Our friend and neighbour Proxima b!
uuh that's very tough! a planet transiting a white dwarf is a big deal, but a terrestrial planet around our nearest star at the right distance is also a big deal! #ExoCup2020
Now we know planets transit white dwarfs, this also opens a new route to searching for biosignatures on terrestrial planets orbiting WDs:

New paper
Could we detect alien life on a planet orbiting a dead star?
It's simple:
1. You can land here
2. Habitable-ish
3. We're VERY close
4. No crushing pressure
5. You're gonna get here SOON
6. Free ice cream
7. We're not a zombie!

I have heard there are awesome barbecue parties on Proxima b during stellar flares. Could you confirm please? 
OK I know when we're beaten. Congratulations to @WD1856_534b on a good win in a hard fought battle. We concede immediately (isn't that how's it meant to work?) 
Sadly the Proxima b Department of Offense (the more aggressive arm, lots of short angry words) are not so gracious and have "insisted" I post this video they created to send a message to Earth (a bit melodramatic you may think...) #ExoCup2020pic.twitter.com/sx8YHZ8TVV
