NASA announces 7th new Earth-like exoplanets discovered, See the live-stream the space agency’s latest exoplanet discovery.
On this Wednesday at 1 pm Eastern, NASA will announce findings on a discovery outside our solar system. No, it is not aliens. It’s never aliens. Rather, NASA is eager to tell us about new exoplanets — planets that orbit stars other than our own — it has found.
NASA has discovered 7 Earth-like planets orbiting a star just 40 light-years away. The announcement will be streamed on NASA’s Youtube channel, watch right here:
The past few years have seen an explosion in the discovery of planets outside our solar system. Astronomers have now confirmed 3,442 exoplanets in the galaxy, and they think there could be 100 billion or more in total.
But astronomers around the world and NASA are not just hunting for any ordinary planets. They are particularly focused on the search for planets in the “habitable zone” of star systems, meaning, in theory, where water could exist on the surface in a liquid form.
Finding Earth-size, potentially habitable planets is believed to be the 1st step to finding other life in the universe.
After discovering these planets, astronomers can observe them more closely and investigate whether their atmospheres contain methane, oxygen, or other telltale gases that signify life.
Last year, the Pale Red Dot project and astronomers at the European Southern Observatory found a potentially habitable planet orbiting the star closest to our own, Proxima B. (Though it may be located dangerously close to its star’s radiation to support life. And actually getting to Proxima B is a whole other story.)
Will today’s announcement be as exciting? It’s possible.
