It is one of the lowest-mass exoplanets yet discovered and has a temperature of about 237☌. Nasa reports that this world is still glowing from the heat of its formation and its colour would appear as a dull magenta. GJ 504 b: the glowing planetįour times bigger than Jupiter, this planet is 57 light years from Earth. It completes one orbit around its star in 25.3 days. The planet, like any other that orbits a pulsar, is inhospitable and is bombarded with constant radiation from its star. Helix Nebula is a phase when a star like the Sun runs out of fuel, it expands and its outer layers puff off, and then the core of the star shrinks. It orbits a pulsar – a rapidly rotating neutron star, which is the dense core of a massive star that exploded. PSR B1257+12 b: ‘creepy’ĭiscovered in 1994, this planet is described by scientists as “one of the creepiest ones”. It is about the size of Saturn and lies in a habitable zone, where liquid water could exist, according to Nasa.ĭiscovered in 2011, the planet orbits stars that are cooler than the Sun. Kepler 16 b: planet with a cool starĬomposed mostly of rock, this planet was the first one discovered by the Kepler telescope to orbit two stars. The planet takes 1.5 days to complete an orbit around its star. It has a dayside temperature of more than 4,315☌ and orbits a star that is almost twice as large and hot as the Sun, which blasts the planet with high levels of ultraviolet radiation. CSds1neKrF- NASA Exoplanets KELT-9 b: scorching temperaturesĭiscovered in 2017, this exoplanet has a mass nearly three times greater than that of Jupiter, but is only half as dense as the planet. ![]() Using these observations, astronomers aim to shine a light on several cosmic mysteries. ![]() NASA’s upcoming Space Telescope will see thousands of exploding stars called supernovae across vast stretches of time and space.
