Researchers believe that GJ 436 b is Neptune-like, meaning it is primarily made of gases rather than metals. Researchers have hypothesised that the planet may be made of an exotic type of water ...

Early targets for investigation include the so-called "Styrofoam world" Kelt-11b; the "lava planet" 55 Cancri-e; and the "evaporating planet" GJ-436b.

This high number, about 10 times higher than GJ 436b, combined with the fact the planet has apparently survived the eons when the star was more active is truly impressive. The team suggests that ...

Hubble found that exoplanet GJ 3470b had lost significantly more mass and had a noticeably smaller exosphere than the first Neptune-sized exoplanet studied, GJ 436b, due to its lower density and ...

One of the planets, named GJ 3470b, is losing its hydrogen 100 times faster than the second, known as GJ 436b. The two planets sit about 2.3 million miles from their star – about one-tenth the ...

Recent findings published in the journal Astronomy and Astrophysics showed that GJ 3470b is vanishing 100 times faster than a similar medium-sized exoplanet, GJ 436b.

The Neptune-size planet, known as GJ 3470b, orbits close to a young, active red dwarf star that lies 97 light-years from Earth. "This is the smoking gun that planets can lose a significant ...

Scientists found that GJ 3470b had lost significantly more mass and had a smaller exosphere than GJ 436b. This is because the former received a stronger radiation blast from its host star, on top ...

Astronomers have used Hubble to nab a second 'very warm' Neptune (GJ 3470b) that is losing its atmosphere at a rate 100 times faster than that of GJ 436b.

The younger star is more energetic, so it bombards the planet with more blistering radiation than GJ 436b receives. Both are red dwarf stars, which are smaller and longer-lived than our Sun.
