Two Potentially Life-Friendly Planets Are Found Orbiting A Nearby Star

Two planets are found similar to Earth that have not been discovered previously and have been hidden in a solar system next to ours, according to scientists.
The sun of these planets is known as the star of Teegarden and is only 12.5 light-years away from us. It is also one of the smallest and best-known stars, making it and its planets very difficult to detect.
Being too dark, the star was spotted in 2003 despite so near to us. But it is also a quiet place without violent solar eruptions or other activity that can eliminate anything that tries to live near it.
These factors, in addition to the relative proximity of the system, make the system an intriguing target for astronomers looking for next-generation telescopes in other worlds and looking for signs of life beyond Earth.
"The two planets of Teegarden are potentially habitable," says Ignasi Ribas, the Institute of Space Studies of Catalonia, a member of the team that reports on the planets today in the journal Astronomy and Astrophysics. "Eventually we will see if they are really habitable and, perhaps, even inhabited."
Now, those who have been studying that faint star say that there are planets floating around them that look a lot like ours, and that they may have the perfect conditions to sustain their own extraterrestrial life.
It is said that one of the two planets are more similar to the one that has been discovered. This is the calculation of how your size compares to the earth and how the temperature might be, but now as well.
On that planet there could be water flowing and rocky worlds. But it will emphasize how much you have left to learn about the worlds, and many of the calculations.
The data says that there is a 60 percent chance that the planet has an environment on its surface, and it is believed that the temperature is available in line with a day in much of the Earth.
"The two planets resemble the inner planets of our solar system," lead author Mathias Zechmeister of the Astrophysics Institute at the University of Göttingen said in a statement. "They are only a little more in the habitable zone, where water can be present in liquid form."
Before the data are likely to see these planets exist, the equipment is described as intrinsic stellar phenomena, such as stars and calls that can be masqueraded as orbiting worlds. Sometimes, this can be quite complicated for red dwarf stars, which are notoriously tempestuous and prone to erupt into massive eruptions. But Teegarden's star is almost eerily silent, making it much easier to unravel planetary signals.
"The number of measurements is so high and the star behaves so well that there is very little room for an alternative explanation," says Ribas. "So, this is, for me, a clear case of planet detection. I would bet my two little fingers that they are there. "
Scientists can see the star from Earth's observatories. They hope to continue examining more closely; looking more closely at the activity and surrounding environment in the hope of learning more about what the conditions on their planets may be like.
