Scientists have discovered an incredible star system, TRAPPIST-1, with seven planets orbiting it. In the initial study, the researchers found that five planets may have liquid water on their surfaces, and three of the seven planets are in orbits within the habitable zone of their stars.

Science discovers new earth-TRAPPIST-1

Scientists say that this may be the “New Earth” we need to find. Of course, the existence of life may not necessarily be based on water. Even if water is possible, we cannot fully discover it. In these existences Among the planets with possible water, our human exploration of space is more about whether we can find a planet suitable for human habitation.

Scientists say Earth doesn’t compare to these planets, nor to most of the planets in TRAPPIST-1. Although the planet has a lot of water, nitrous oxide only accounts for 0.02% of our planet’s mass. The rest is rock, metal and organic material equal to Earth-like material. By comparison, some planets around TRAPPIST-1 may have water making up 15% of their mass or more.

Scientists have found through observation results that our initial estimate of the proportion of water is much smaller. In fact, the water present on these planets may be more than 250 times the water in the Earth’s oceans. These planets look like they are all made of water, and are even larger than the satellites from Enceladus. The Earth’s water resources are far from comparable to those of the TRAPPIST-1 planets.

Scientists say that in our solar system, planets closer to the sun tend to be dry, while planets farther away tend to be dry. In the TRAPPIST-1 system, even planets close to the sun have high concentrations of water. This means the planets may have had to shift positions over time, something astrophysicists are still exploring. Observations suggest that if the planets formed eight billion years ago, the migration could be considerable, or if the planets formed slowly over time, they could move only a small amount.
