Astronomers have discovered a water-rich atmosphere on exoplanet GJ 9827 d, located 98 light-years away in the constellation Pisces.Using the James Webb Space Telescope (JWST), researchers ...

A Canadian-led international study has revealed new insights into the atmosphere of GJ 9827 d—an exoplanet orbiting the star GJ 9827 in the constellation Pisces, about 98 light-years from Earth ...

GJ 9827 d is a sub-Neptune (1.98 Earth radius) just above the radius valley, but it is interesting even so. With a mass of 3.02 M⊕ and a radius of 1.98 R⊕, GJ 9827 d hugs the upper size end ...

Scientists envision that this steam world has a thick, water-rich atmosphere, with a surface free from ice or flowing water. Researchers suggest that GJ 9827 d resembles what icy moons of Jupiter ...

This process, called atmospheric retrieval, revealed that GJ 9827 d's atmosphere is likely composed almost entirely of water vapor. Engineers mount Webb's NIRSpec onto a stand in NASA Goddard's ...

The planet, known as GJ 9827 d, is roughly twice the size of Earth and has an atmosphere composed almost entirely of water vapor, according to a new study. “This is the first time we’re ever seeing ...

Astronomers have theorised that such planets exist, but this study represents the first observational confirmation of a steam world. And, although GJ 9827 d can’t support life as we know it ...

As detailed in a new study published in The Astrophysical Journal Letters, the planet dubbed GJ 9827 is twice the size of Earth and is located roughly 100 light years away.. This sort of hot ...

GJ 9827 d was first discovered by the Kepler space telescope in 2017. The exoplanet is located just 5.2 million miles (8.4 million kilometers) from its host star, GJ 9827, which is around 6% of ...

GJ 9827 d itself isn't a new discovery; NASA's Kepler space telescope found it back in 2017. After the agency worked with the European Space Agency (ESA) and the Canadian Space Agency ...

A steam-shrouded planet unlike any we’ve seen before has been detected nearly 100 light years away. The planet, known as GJ 9827 d, is roughly twice the size of Earth and has an atmosphere ...
