Ascenso y caída de la nebulosa Mantarraya. Hablamos con Martín Guerrero Roncel.

Hoy vamos a visitar una nebulosa situada a 18.000 años luz, en la constelación Ara (Altar), que lleva el nombre de Mantarraya, llamada así porque algunos astrónomos, tirando de imaginación, encontraron en ella un parecido con ese animal marino. Un grupo de investigadores, entre los que se encuentra nuestro invitado, Martín Guerrero Roncel, del IAA – CSIC, comparando las imágenes de la nebulosa obtenidas por el Telescopio Espacial Hubble en 1996 y 2016, ha descubierto que la nebulosa ha sufrido cambios importantes en muy pocos años, unos cambios provocados por variaciones en la estrella de la que surgió. El resultado de la investigación ha sido publicado recientemente en la revista The Astrophysical Journal. Más información en https://cienciaes.com
