An international research team led by the University of Göttingen has discovered two new Earth-like planets near one of our closest neighboring stars. "Teegarden's star" is only about 12.5 light years away from Earth and is one of the smallest known stars. It is only about 2,700 °C warm and about ten times lighter than the Sun. Although it is so close to us, the star wasn't discovered until 2003. The scientists observed the star for about three years. The results were published in the journal Astronomy and Astrophysics.
Their data clearly show the existence of two planets. "The two planets resemble the inner planets of our solar system," explains lead author Mathias Zechmeister of the Institute for Astrophysics at the University of Göttingen. "They are only slightly heavier than Earth and are located in the so-called habitable zone, where water can be present in liquid form."

That’s a really small star. The “years” for the planets must be a few days at most.

Victims of the earth transfer portal.

That's it? Field trip!

Exciting stuff. There is so much we don't know. Just think, if we would resume our focus on space travel, just think what could happen. Within generations, the possibility of sending colonists to another world could be possible, if advances in propulsion are sufficient.
Just looked and we now have 5 candidate planets that are anywhere from 6 to 12 light years away. All of them orbit red dwarf stars. I wonder what life on a planet with mostly infrared light would be like?

I hope the James Webb Space Telescope will be able to tell us if there are atmospheres around them. Then other telescopes can look for biomarkers such as oxygen and industrial pollutants.

Propulsion isn’t as big a hurdle right now as what space travel does to the human body. We still haven’t figured out how to shield ourselves adequately from cosmic rays the way our atmosphere does. Doing a tour on the ISS right now is like living inside a microwave for a period: you increase your radiation exposure and thus your cancer risk exponentially. Manned space travel beyond the moon is at this juncture a suicide mission. We have much to learn.

Wasn't it supposed to be launched this year? Is it up there yet?

It was originally scheduled to be launched in 2009 at a cost of $500 million. A series of delays and cost over runs pushed the launch date to October of 2018 at a cost of nearly $5 billion. The latest projected launch date is March of 2023 and the cost has ballooned to an astounding $10 billion. It is becoming an embarrassment for NASA. If it never launches, and the possibility is distinct, it could damage NASA’s long term space program.

I for one will be extremely disappointed if it never reaches orbit. Such a tease.

It's design is so incredibly complex that I fear even one small glitch will sabotage the entire mission. Furthermore, the Lagrange point where it will be stationed is so far from earth that there will be no way it can be serviced. If it does actually get launched and performs, it will be one of the greatest successes of our space program.
