NASA Discovered a Potentially Habitable Planet – An Alternative To Mars?

A groundbreaking discovery has just taken place, as scientists at NASA have shared the existence of a habitable planet that could potentially sustain life. And the news gets better, the planet is only a brief 100 light-years away. Named TOI 700 e, this planet shared a similar size to Earth and orbits a red dwarf star (TOI 700) alongside its planetary siblings, TOI 700 b, c, and d (yes, very imaginative bunch a NASA when it comes to naming things).1

TOI 700 e is roughly 95% the size of Earth and is a rocky planet similar to our own. What makes TOI 700 e so special is that it is positioned in the optimistic habitable zone of its star. This means it holds promise for harboring conditions conducive to life (making it “habitable“, much like its sibling, TOI 700 d.2

The habitable zone, often dubbed the “Goldilocks zone,” references the sweet spot around a star where temperatures are just right for liquid water to exist on the planet’s surface. Emily Gilbert, a postdoctoral fellow at NASA’s Jet Propulsion Laboratory, states that “This is one of only a few systems with multiple, small, habitable-zone planets that we know of.”

The discovery of TOI 700 e highlights how far we have come with cutting-edge technology like the Transiting Exoplanet Survey Satellite (TESS), designs ed monitor changes in brightness levels to show orbiting planets. The faint signal TOI 700 put out required an extended observation, showing the precision and capabilities of our scientists and the modern astronomical technologies.3

Beyond our solar system, scientists continue to search for a habitable planet. TOI 700 e joins a small list of other potentially life-supporting exoplanets, hopefully continuing a trend in finding more of humanity’s osmic neighbors.4

As astronomers continue to look futher into the mysteries a distant habitable planet may be hiding, they also strive better understand planetary formations and evolution. Keeping a keen eye on systems like TOI 700 will help unlock insights into the conditions necessary for life beyond Earth.

The existence of TOI 700 e marks a pivotal moment in humanity’s exploration of the cosmos. As our understanding of other worlds continues to develop, so too does our capacity to better ask the question: Are we alone in the universe? With each new discovery, we get just a little closer to unraveling the our cosmic existence with any other habitable planet we discover.
