Hello everyone! This is Moonid and today I bring you my highlights for the NASA Press Conference that happened on Feb. 22 at 1 pm EST.

The conference was pretty simple, with a lot of time spent on answering questions from people all around the world. If you want to watch the whole press conference, you can watch it below (video taken from NASA Youtube Channel):

For this highlight, I will write about the following:

  1. What was the conference about?
  2. Information about TRAPPIST-1
  3. What´s next?
  4. Remarkable Q&A

Highlights


  • What was the conference about?

The conference was about a big announcement that NASA had to share with the whole world. They found that in TRAPPIST-1, a star system which is around 40 light years away from our solar system, there are seven Earth-sized planets (they are considered as Exoplanets). Three out of the seven have a good possibility to contain Earth´s properties and be able to sustain life.

The discovery of TRAPPIST-1 System was made months ago in a space lab on Chile, but it was not until recently that they could confirm the 7 exoplanets.

  • Information about TRAPPIST-1

In the image down below, we can see the comparison between both TRAPPIST-1 System and our own Solar System. Everything seems to be in scale except for our Sun.

The letters that accompany each exoplanet is, at the moment, the name given to each one (e.g. TRAPPIST-b, TRAPPIST-c, and so on and so forth).

The “sun” in TRAPPIST-1 is a much smaller sun and cooler than ours. Each exoplanet revolves around the “sun”, but they don´t rotate due to a lack of rotation axis. That means that they have a permanent side looking at the “sun”, and a permanent dark side.

If you watch closely at the image above, there is a green ring in the TRAPPIST-1. That green area is the Habitable Zone and all the exoplanets inside of it have the possibility to sustain lifeforms (that is, exoplanet e, f, and g). There is a high chance to find water on the surface on any of these 3 exoplanets.

In summary, NASA found three habitable exoplanets which have the possibility to contain lifeforms or be able to sustain it.

  • What´s next?

By 2018, a new telescope will be released which will be the pride of NASA. It´s called the James Webb Space Telescope (JWST). With it, they intend to study more about TRAPPIST-1, specifically e, f, and g. For now, the Hubble Telescope + all the grounded telescopes will focus on studying the TRAPPIST-1.

The next step to discover would be if the atmosphere in these three planets are similar to ours, find if there is any new gas we don´t know, compositions of the planet, and so on. They are still on the initial phase, but this new is a huge leap to the discovery of life out of our planet.

  • Remarkable Q&A

There were some interesting questions from the Q&A, which users who asked I don´t remember (you can check the press conference video to know who asked what).

Someone asked how much time do they need to have more information about e,f, and g, and the experts said that after JWST launches, it would take roughly 5 years.

Another person asked whether there was any “noise” coming from these exoplanets. The experts said that no “noise” signal had been picked so they inferred that there is no advanced civilization in any of these exoplanets (whew! no alien invasions).

There was also someone asking whether any of these exoplanets had any moons, which the experts replied that there is none at the moment.

There were other questions, but I found the ones I mentioned the most interesting.
