Scientists from NASA announced Tuesday that they discovered an Earth-size planet orbiting its star's habitable zone.
Working with data from NASA’s Transiting Exoplanet Survey Satellite, or TESS, Michigan State University has helped discover an Earth-sized exoplanet — a planet outside of our solar system.
This planet, named TOI-700 e, falls within its star’s habitable zone, meaning the newfound planet could be capable of supporting life as we know it. The research team announced the finding Jan. 10 at the American Astronomical Society meeting in Seattle.

Astronomers believe that many such planets exist in our galaxy and across the universe. The discovery of TOI-700 e, along with the earlier confirmation of its host system, could provide unique opportunities to better explore exoplanets going forward
“Even with more than 5,000 exoplanets discovered to date, TOI-700 e is a key example that we have a lot more to learn,” said Joey Rodriguez, an assistant professor in the Department of Physics and Astronomy at MSU, who helped make the discove
Rodriguez was one of the senior researchers on the project, led by Emily Gilbert, a postdoctoral fellow at NASA’s Jet Propulsion Laboratory in Southern California. The duo is also part of the original team that confirmed the TOI-700 system in 2020, finding it had at least three planets (named TOI-700 b, TOI-700 c and TOI-700
With the new discovery, the team showed that the TOI-700 system has two Earth-sized planets within its habitable zone

2 planets in this system reside in the habitable zone. Problem with red dwarf stars and the proximity to planets is the solar flares.
They are known to torch entire sides of the surface every 20 years or so.
Stellar flares from red dwarfs are particularly bright in ultraviolet wavelengths, compared with Sun-like stars. Hubble's ultraviolet sensitivity makes the telescope very valuable for observing these flares. The flares are believed to be powered by intense magnetic fields that get tangled by the roiling motions of the stellar atmosphere. When the tangling gets too intense, the fields break and reconnect, unleashing tremendous amounts of energy.
The team has found that the flares from the youngest red dwarfs they surveyed — just about 40 million years old — are 100 to 1,000 times more energetic than when the stars are older. This younger age is when terrestrial planets are forming around their stars.
Approximately three-quarters of the stars in our galaxy are red dwarfs. Most of the galaxy's "habitable-zone" planets — planets orbiting their stars at a distance where temperatures are moderate enough for liquid water to exist on their surface — likely orbit red dwarfs. In fact, the nearest star to our Sun, a red dwarf named Proxima Centauri, has an Earth-size planet in its habitable zone.
However, young red dwarfs are active stars, producing ultraviolet flares that blast out so much energy that they could influence atmospheric chemistry and possibly strip off the atmospheres of these fledgling planets.
"The goal of the HAZMAT program is to help understand the habitability of planets around low-mass stars,

Early formation of stars those less than 100 million years old is voluble.
Their are chances that the star can split into binary patterns... Star fission is the splitting of a star at a critical angular momentum, or period in its history, with the consequence of zero-age contact in the resultant binary star. This splitting may have its highest probability of occurring during early star formation.
To later remerge in star fusion... The results are cataclysmic any star within 100 lt years can be voided by resulting rush of plasma from neighbor super novas... These gasses are hard to define during the event they race outside of space and time measurements and with more force than the entire known stable universe...

Interesting, thx for sharing .... need to point that James Webb telescope at our neighbors.
We need to find a planet possibly revolving around a larger planet as a satellite moon that has liquid water temperature varies between 32 and 90o F. And a similar mass with a star of yellow medium to white dwarf
Nearer to the center of a milky way....
That would be ideal for condition for life here to evolve their.

A possible algorithms is a appearance changing star.
Say a red white and yellow stars near similar in size creating a revolvement in trinary pattern at low magnitude from normal telescopes.
It's appearance would be light orange to lt yellow to emergence of a rainbow feature due to where earth is to what cycle the revolution of star pattern appeared....
This area would have a vast space of habitable zones for Earth like planet...
But too hot or cold...

In a trinary star system, two of the stars orbit each other as a binary pair, while the third star orbits the pair at a greater distance. This ensures that the system is stable, since if the inner and outer orbits were the same size, one of the stars would eventually be ejected from the system.May 7, 2020
This specific trinary system in volves a black hole. discovery that a black hole can be part of a trinary star system is also relevant because astronomers have suggested that such triple systems could be progenitors of binary systems with two black holes, or a black hole/neutron star pairing. When the partners in those binary systems merge, the violent event emits gravitational waves that can be detected by the LIGO collaboration. But their must be a continuous stable systems...

Problem with dying stars and collapse of eco system...
Energy emitted is beyond known space as stars collapse explode and become nebula regions.
Evidence for Elusive Mid-Sized Black Hole Astronomers have found the best evidence for the perpetrator of a cosmic homicide: a black hole of an elusive class known as "intermediate-mass," which betrayed its existence by tearing apart a wayward star that passed too close.
Weighing in at about 50,000 times the mass of our Sun, the black hole is smaller than the supermassive black holes (at millions or billions of solar masses) that lie at the cores of large galaxies, but larger than stellar-mass black holes formed by the collapse of a massive star.
These so-called intermediate-mass black holes (IMBHs) are a long-sought "missing link" in black hole evolution. Though there have been a few other IMBH candidates, researchers consider these new observations the strongest evidence yet for mid-sized black holes in the universe.
It took the combined power of two X-ray observatories and the keen vision of NASA's Hubble Space Telescope to nail down the cosmic beast.
