Astronomers have found something they thought was impossible: a gas giant roughly the size of Jupiter orbiting a white dwarf half the mass and size of the Sun.
The planet, called NGTS-1b, is a record breaker – the largest planet compared to its star ever found, at a ratio that scientists weren’t even sure was possible. This discovery could pose a challenge to our current theories about planetary formation.
“The discovery of NGTS-1b was a complete surprise to us – such massive planets were not thought to exist around such small stars,” said lead researcher Daniel Bayliss of the University of Warwick.
“This is the first exoplanet we have found with our new NGTS facility and we are already challenging the received wisdom of how planets form.
“Our challenge is to now find out how common these types of planets are in the galaxy, and with the new NGTS facility we are well-placed to do just that.”
Observed using the Next-Generation Transit Survey wide-field telescope array, NGTS-1b is about 600 light-years from Earth. It is what’s known as a “hot” Jupiter, a gas giant that is of a similar size to Jupiter but much closer to its host star – therefore hotter, and with a much smaller orbital period.
