Yet, these cosmic detectives came up empty-handed time after time – until now, with the JWST turning the tables. "GJ 1214b ...

Initially pegged as an ocean planet, GJ 1214 b was endearingly termed a "waterworld" in academic circles. ... "GJ 1214b has been the white whale of exoplanet atmosphere characterisation the whole ...

It looks like GJ 1214b might have an atmosphere that's made mostly out of water." That pushes this planet into "a category of its own in a way that was never certain before," says Kreidberg.

"GJ 1214b, based on our observations, could be a water world," Kempton said. "We think we detect water vapor, but it's challenging because water vapor absorption overlaps with methane absorption ...

While studying GJ 1214b, researchers tracked the planet through nearly its entire orbit over the course of about 40 hours, according to NASA. The planet's year takes only 1.6 Earth days.

Our own solar system has nothing like this planet, called GJ 1214b. It's bigger than the rocky planets like Earth, but still smaller than any of our system's ice or gas giants.

A team of researchers used the James Webb Space Telescope to observe exoplanet GJ 1214b’s atmosphere by measuring the heat it emits while orbiting its host star. Their results, published in the ...

The temperature on GJ 1214b shifted dramatically from day to night, getting as hot as 535 degrees Fahrenheit (280 degrees Celsius) and then cooling down by more than 100 degrees F at night.

She says astronomers have zeroed in on GJ 1214b in particular because it's the single-most accessible planet like this to observe. It orbits a small yet bright star that's relatively nearby, just ...

An enigmatic, cloud-enshrouded planet that has puzzled astronomers for years turns out to be less hot than expected – and surprisingly shiny. That's what the James Webb Space Telescope revealed when ...

It looks like GJ 1214b might have an atmosphere that's made mostly out of water." That pushes this planet into "a category of its own in a way that was never certain before," says Kreidberg.

Astronomers pointed the James Webb Space Telescope at a common kind of planet that's bigger than Earth but smaller than Neptune. What they saw wasn't what they expected.
