¿Qué intentan decirnos estos terrícolas? El mensaje presentado fue enviado desde la Tierra hacia el cúmulo estelar globular M13 en 1974. Durante la inauguración de una mejora en el Observatorio de Arecibo, que en ese momento era el radiotelescopio único más grande del mundo, se transmitió una cadena de unos y ceros que representan este diagrama. Este intento de comunicación extraterrestre fue más ceremonial, ya que la humanidad regularmente transmite señales de radio y televisión hacia el espacio de manera accidental. Aunque este mensaje fuera recibido, M13 está tan lejos que deberíamos esperar casi 50,000 años para escuchar una respuesta. El mensaje contiene algunos datos sencillos sobre la humanidad y su conocimiento: de izquierda a derecha se muestran números del uno al diez, átomos como hidrógeno y carbono, algunas moléculas interesantes, ADN, un ser humano con su descripción, los conceptos básicos de nuestro Sistema Solar y aspectos básicos del telescopio emisor. Actualmente, se están llevando a cabo diversas búsquedas de inteligencia extraterrestre.

Robert H. Goddard, considerado el padre de la cohetería moderna, nació en Worcester, Massachusetts en 1882. A los 16 años leyó el clásico de ciencia ficción 'La guerra de los mundos' de H.G. Wells y soñó con viajes espaciales. Para 1926 había diseñado, construido y volado el primer cohete de combustible líquido del mundo. Lanzado hace 100 años, el 16 de marzo de 1926, desde la granja de su tía Effie en Auburn, Massachusetts, el cohete llamado 'Nell' alcanzó una altitud de 41 pies en un vuelo que duró aproximadamente 2 segundos y medio. En esta foto posada, Goddard aparece junto al cohete de 10 pies de altura, sosteniendo el marco del soporte de lanzamiento. Para lograr un vuelo estable sin aletas, el motor pesado del cohete estaba ubicado en la parte superior, alimentado por líneas desde los tanques de oxígeno líquido y gasolina en la parte inferior. Reconocido ampliamente como un experimentador dotado y un genio de la ingeniería, sus cohetes estaban adelantados a su tiempo. Goddard recibió más de 200 patentes en tecnología de cohetes, la mayoría póstumas tras su muerte en 1945. Un cohete de combustible líquido construido siguiendo los principios desarrollados por Goddard llevó a los humanos a la Luna en 1969.

Hickson 44 in Leo

#APOD #NASA

Explorando el cielo en busca de galaxias, el astrónomo canadiense Paul Hickson y su equipo identificaron alrededor de 100 grupos compactos de galaxias, conocidos como Grupos Compactos de Hickson. Las cuatro galaxias prominentes visibles en esta imagen telescópica son un ejemplo de estos grupos, el Hickson 44. Este grupo de galaxias se encuentra a unos 100 millones de años luz, más allá de las estrellas de la Vía Láctea en primer plano, hacia la constelación de Leo en primavera. Las dos galaxias espirales en el centro de la imagen son NGC 3190, vista de canto con distintivas y torcidas líneas de polvo, y la NGC 3187 con forma de S. Junto con la brillante elíptica NGC 3193 (a la izquierda), estas forman parte también del grupo Arp 316. La espiral en la esquina inferior derecha es NGC 3185, el cuarto miembro del grupo Hickson. Estas galaxias muestran signos de distorsión y formación estelar intensificada, evidencia de una lucha gravitacional que eventualmente llevará a fusiones galácticas en escalas cósmicas de tiempo. Este proceso de fusión es ahora comprendido como una parte normal de la evolución de las galaxias, incluida nuestra propia Vía Láctea. Para referencia, NGC 3190 tiene aproximadamente 75,000 años luz de ancho considerando la distancia estimada para Hickson 44.
