Finding the Next Earth

PSR B1257+12: was the first confirmed discovery of extrasolar planet in 1992 . As of 2019, there will be over 4000 confirmed exoplanets, roughly 2500 of which were discovered between 2014-2016. This 2011 documentary shows the dawn of these discoveries and focus on planets that could perhaps resemble Earth in size and conditions. The "Goldilock" planets.

From Space, Europe, North and South America, powerfull telescope are now pointed to the skies in searchof these possibilities. The documentary is interesting enough and brings worthwhile comments fromthe interviews and bring you there with footage to fuel your imagination. One big mistake for a science documentary talking about space is to use outdated Fahrenheit scale / Imperial system / US Customary Units. Only 3 countries out of 196 (USA, Liberia and Myanmar) use this system and no scientific articles, journals or other refer to it. When you mention a temparatre of -450 degrees and you do not even mention it is F, it is a big dissapointing. Absolut zero is -273.15C so it looks like the scientific writers or editors of this doc did take their audience for granted. They could have at least mentioned both Celisius and Fahrenheit are explain that 450F is close to abosulte zero 459.67F and not below absolut zero which is of course impossible.

Use Kelvin or Celcius please! It is for your own credibility.

Other than these minor flaws, this doc is worth your time.

Let's hope the funding and time to find these planets and study them do not stop.
