Dead planets may be signaling in outer space

Scientists say the dead planets may be sending signals we can get on Earth.

Scientists hope to be able to listen to them, yearn to find the cores of planets and learn more about the vast universe.

Researchers have seen planets orbiting stars that have destroyed them: "When the sun burns all its fuel and peels off its outer shell, it will destroy nearby objects and burn it. burning their outer layers ".

Research can help reveal the future of the Solar System.

The remnant planets' cores can be seen in space and exist long enough to be detected from Earth.

The technique used to view these planets is based on a similar technique that researchers used to find the first confirmed extraterrestrial planet. To search for a planet, scientists look for radio waves emitted by its star and hope they can see white dwarfs by following similar energy pulses.

A white dwarf and its stripped planetary core could all create an electrical circuit. They help amplify and transmit signals in space, meaning that it can be detected by radio telescopes on Earth.

Scientists need to do more research to find out how long the cores can survive after they are removed from the outer layer and whether they will continue to broadcast in space.They discovered that these cores could exist for up to a billion years, meaning that signals could exist long enough to be able to detect them from Earth.

Researchers are hoping that their observatories can find potential candidates soon and uncover messages.

Dr Dimitri Veras from the University of Warwick said: "There is an advantage to discovering these planetary cores: a core too close to the white dwarf will be destroyed by tidal forces and a core too far away will not be able to detect. In addition, if the magnetic field is too strong, it will push the core into the white dwarf and destroy it, so we should only look for planets around white dwarfs with weaker magnetic fields in the distance between about 3 solar radii and the distance from the sun to the sun No one has ever found the bare core of a large planet or just by monitoring magnetic signals or a large planet orbiting the star White dwarf. Therefore, the discovery here will represent 'firsts' in three different meanings to the planetary system. "

"We will use the results of this work as a guide for radio wave design for the core of the planet around the white dwarf," said Alexander Wolszczan of Pennsylvania State University . Given the presence of planetary debris around many of them, we think the opportunity for our exciting discoveries is quite promising. "

Dr Veras added: "Just finding a core will help reveal the history of these star systems, because by the time a core reaches that stage, it will have no atmosphere and no coating at one. score and then being pushed towards the white dwarf. Such a core can also give us a glimpse of our own far future and the future of our Solar System. "
