Scientists Discover Earth's 'Toasty Twin'; Say It May Be the Most Important Exoplanet
Scientists Discover Earth's 'Toasty Twin'; Say It May Be the Most Important Exoplanet
Jan 17, 2024 3:37 PM

Astrophysicists revealed a newfound world this week, and scientists say it has enough in common you could almost mistake it for Earth's twin.

Named , which is pretty close onsidering the massive size of the universe. According to University of Maryland’s Drake Deming, its proximity and its eerie resemblance to Earth make it “arguably the most important planet ever found outside the solar system,” reports USA Today.

A team pioneered by Massachusetts Institute of Technology’s Zachory Berta-Thompson with the use of telescopes in Chile, according to NBC News. They estimate that the planet has a diameter of about 9,200 miles, slightly larger than that of Earth. However, its mass is believed to be about 60 percent greater than Earth’s. He believes this new world is “going to be a favorite target of astronomers for years to come.”

Though this new planet may have some things in common with our home planet, one major difference is its intense heat.

The coolest part of GJ 1132b’s atmosphere ranges from, which is likely too hot to support life. Earth-sized planets outside the solar system tend to be so blazingly hot that an atmosphere would not be able to survive, however, GJ 1132b may be surrounded by the same gasses wrapped around the Earth.

“If we find this pretty hot planet has managed to hang onto its atmosphere over the billions of years it's been around, that bodes well for the long-term goal of studying cooler planets that could have life,” said Berta-Thompson in a statement.

GJ 1132b , which makes it easier to study than if it were circling a more brilliant star. It is only 21 percent the size of the sun and emits one-half a percent as much light, according to Space.com. The light from the star does not overwhelm any reflected light that from the planet that could be collected.

Red dwarfs also tend to be more plentiful and, in our galaxy, outnumber stars such as the sun. This means the planet may become , according to Boston University astronomer Phili Muirhead.It , thus creating the heat wave on the planet.

Although , it was cool enough to support some of the basic building blocks of life and possibly support life forms like bacteria, according to Mount Stroll Observatory astronomer Brad Tucker.

“We haven’t found anything close to this so far. It’s more habitable, it’s less harsh and this gives us a good, strong chance of actually finding life or something as opposed to the other Earth-like planets found to date,” said Tucker.

GJ 1132b could become , or its predecessor, the James Webb Space Telescope, which is scheduled to launch in 2018.
