Are they contacting us from Alpha Centauri?/¿Nos contactan desde Alfa Centauri?

In December of last year, they announced from the Parker telescope in Australia the detection of a radio signal in the frequency of 982.002 MHz emitted in principle from Alpha Centauri, the closest star to the Sun "only" 4.2 light years and that it has an exoplanet in its habitable zone, that is, an orbit in which water could be found in a liquid state, essential for life.

>En diciembre del año pasado anunciaban desde el telescopio Parker en Australia la detección de una señal de radio en la frecuencia de 982.002 MHz emitida en principio desde Alpha Centauri, la estrella más cercana al Sol a "tan solo" 4,2 años luz y que posee un exoplaneta en su zona habitable, es decir, una órbita en la que podría encontrarse agua en estado líquido esencial para la vida.

This telescope is part of the Breakthrough Listen project created among others by Stephen Hawking, which aims to scrutinize the million stars in our galaxy closest to Earth in search of some evidence of extraterrestrial life, using the most innovative technologies available to us in the present world.

This signal has been baptized as BLC1 (Breakthrough Listen Candidate 1) and has characteristics, such as its blue shift due to the Doppler effect (which we have already discussed at some point in this medium), which could coincide with the movement of the exoplanet Proxima B orbiting our neighbor Alpha Centauri.

>Esta señal ha sido bautizada como BLC1 (Breakthrough Listen Candidate 1) y presenta características, como su corrimiento al azul debido al efecto doppler (que ya hemos comentado alguna vez en este medio), que podría coincidir con el movimiento del exoplaneta Proxima B que orbita a nuestra vecina Alpha Centauri.

Unfortunately it was a false alarm, after a more exhaustive study scientists have come to the conclusion that it is not an extraterrestrial signal but some interference originated in our planet, a shame because although it is something difficult to implement it would be possible in a near future send a probe that could yield results in a reasonable time.

>Lamentablemente era una falsa alarma, después de un estudio mas exhaustivo los científicos han llegado a la conclusión de que no se trata de una señal extraterrestre sino de alguna interferencia originada en nuestro planeta, una pena porque aunque es algo difícil de implementar sería posible en un futuro cercano enviar a alguna sonda que pudiese arrojar resultados en un tiempo razonable.

For this purpose, there is the Breakthrough Starshot variant that aims to send small probes attached to a solar sail propelled by beams of laser rays projected from the Earth, with which they could reach 20% of the speed of light (about 150 million km / h) which would allow us to reach Alpha Centauri in about 20 years, which is still a long time but could be carried out in the course of a human life.

>Para este fin existe la variante Breakthrough Starshot que se propone enviar pequeñas sondas atadas a una vela solar propulsada por haces de rayos láser proyectados desde la Tierra, con las que podrían alcanzar un 20 % de la velocidad de la luz (unos 150 millones de km/h) lo que nos permitiría alcanzar Alpha Centauri en unos 20 años que, sigue siendo mucho tiempo pero podría llevarse a cabo en el transcurso de una vida humana.

This star also has the peculiarity that, in its continuous movement through the cosmos, it has become the closest star to the Sun approximately the same time ago that humanity appeared on Earth, which excites the minds of those who like to speculate with the unknown and the esoteric.

>Esta estrella tiene además la particularidad de que, en su continuo movimiento por el cosmos, ha pasado a ser la estrella más cercana al Sol hace aproximadamente el mismo tiempo que la humanidad apareció en la Tierra, lo que excita las mentes de los que les gusta especular con lo desconocido y lo esotérico.

What is clear is that, given the vast number of galaxies with hundreds of billions of stars each with their planets, it is extremely unlikely that we are alone in the universe and I suppose it is a matter of time before we come across some alien, lets hope they are not as assholes as humans.

>De lo que no cabe duda es de que, dada la ingente cantidad de galaxias con cientos de miles de millones de estrellas cada una con sus planetas, es extremadamente improbable que estemos solos en el universo y supongo que es cuestión de tiempo que nos topemos con algún alienígena, espero que no sean tan capullos como los humanos.

Curioso, la frecuencia es la mitad de la del Wifi, a ver si quieren conectarse a Starlink.

Es raro que la interferencia sea terrestre y venga de Alpha Centauri el sistema más cercano.

Tampoco me des demasiado crédito que no soy Carl Sagan.
