Astrophysicists were able to capture a signal from the planet Gliese 581d. Experts have already stated that the exoplanet has all the conditions to support life.
It is already known that the size of this planet is twice the size of the Earth. Scientists refute the information that the signals that were recorded earlier are noise. They were able to establish that they are repetitive and cyclical.
Recall that in 2014, experts from Pennsylvania stated that the signals received earlier were a play of light and magnetic radiation. It is they who, in the process of crossing, make this kind of noise.
However, despite such statements, specialists from Britain were skeptical about such a message, they continue to insist that the signals are interference, and soon it will be possible to receive a real message from the exoplanet Gliese 581d.

Gliese 581 d (Gliese 581 d) is an unconfirmed exoplanet in the planetary system of the red dwarf Gliese 581, located only about 20 light years from Earth in the constellation Libra.
It was assumed that the planet is the fifth in the system (as of September 2010) in terms of distance from the star. Because of its mass, the planet is classified as a "super-earth" (its mass is approximately 6-8 times the mass of our planet), and was approximately 2 times larger than the Earth in size.

There is debate over the existence of the planet.
The announcement of the discovery of the planet was made by the European group of astronomers Stephen Hudry (Geneva Observatory, Switzerland) on April 24, 2007, in conjunction with the discovery of Gliese 581 c.
Two weeks after the report of the discovery, scientists at the University of Geneva said that with the help of the European Southern Observatory's HARPS, they could not detect signs of the planets Gliese 581 d and Gliese 581 g. In 2012, a Russian astronomer at the Pulkovo Observatory, Roman Baluev, expressed serious doubts about the reality of the planet Gliese 581 d.
In July 2014, scientists at the University of Pennsylvania, using calculations, disproved the existence of the planets Gliese 581 d and Gliese 581 g, stating that the observed phenomena were in fact artifacts of stellar activity, but in March 2015 researchers from Queen Mary University in London (QMUL) and the University of Hertfordshire, stated that the methodology used by their American counterparts was not perfect for refuting the existence of the planet.
