Possibly habitable Trappist-1 exoplanet caught destroying its own atmosphere

"I would imagine that all Trappist-1 planets are going to have a hard time holding on to any atmosphere."

Trappist-1 circles a Red Dwarf Star along with 7 other planets 3 are in the Goldilocks Zone. But the other 3 planets may be in danger of the same solar winds affecting there magneto sphere l.

The seven worlds of TRAPPIST-1 are the most intriguing exoplanetary system discovered so far. What are these planets like, and could they su

The Trappist-1 system is located just 40 light-yearswithin range of the James Webb Space Telescope (JWST). This means that JWST can probe the atmospheres of the TRAPPIST-1 planets.

Earth-Sized Planet Found in the Habitable Zone of a Nearby Star

👏👏👏 NASA TESS team. Planet TOI-700 d is “100 light-years from Earth in the constellation Dorado”.

A few months ago, a group of NASA exoplanet astronomers, who are in the business of discovering planets around other stars, called me into a secret meeting to tell me about a planet that had captured their interest. Because my expertise lies in modeling the climate of exoplanets, they asked me to figure out whether this new planet was habitable — a place where liquid water might exist.

These NASA colleagues, Josh Schlieder and his students Emily Gilbert, Tom Barclay and Elisa Quintana, had been studying data from TESS (Transiting Exoplanet Survey Satellite) when they discovered what may be TESS' first known Earth-sized planet in a zone where liquid water could exist on the surface of a terrestrial planet. This is very exciting news because this new planet is relatively close to Earth, and it may be possible to observe its atmosphere with either the James Webb Space Telescope or ground-based large telescopes.

Habitable zone planets

The host star of the planet that Gilbert's team discovered is called TESS of Interest number 700, or TOI-700. Compared to the Sun, it is a small, dim star. It is 40% the size, only about 1/50 of the Sun's brightness and is located about 100 light-years from Earth in the constellation Dorado, which is visible from our Southern Hemisphere. For comparison, the nearest star to us, Proxima Centauri, is 4.2 light-years away from Earth. To get a sense of these distances, if you were to travel on the fastest spacecraft (Parker Solar Probe) to reach Proxima Centauri, it would take nearly 20,000 years.

There are three planets around TOI-700: b, c and d. Planet d is Earth-size, within the star's habitable zone and orbits TOI-700 every 37 days. My colleagues wanted me to create a climate model for Planet d using the known properties of the star and planet. Planets b and c are Earth-size and mini-Neptune-size, respectively. However, they orbit much closer to their host star, receiving 5 times and 2.6 times the starlight that our own Earth receives from the Sun. For comparison, Venus, a dry and hellishly hot world with surface temperature of approximately 860 degrees Fahrenheit, receives twice the sunlight of Earth.

Possible climates for planet TOI-700 d

Based on our models, we found that if the atmosphere of planet TOI-700 d contains a combination of methane or carbon dioxide or water vapor, the planet could be habitable. Now our team needs to confirm these hypotheses with the James Webb Space Telescope.

Entirely fictional bacterial colonies grow above shallow sandbars on planet Aulta. Underneath the surface, there’s firey glowing hydrothermal vents. A recipe for life on a new planet!

NASA found seven Earth-sized planets orbiting a nearby star

The star TRAPPIST-1 is an ultracool dwarf just 39 light years away from the Sun and as many as six of these planets are believed to be rocky worlds, of which three could support liquid water. This is pretty unprecedented. Read more here.

So now at least you have a plausible setting for your multiple-races hard sci-fi RPG campaign, and yet another destination for humanity’s first relativistic starship.
