Einem internationalen Team von Astronomen ist es mithilfe von Daten des Hubble-Weltraumteleskops gelungen, eine bisher nicht beobachtete Sternentwicklung in Echtzeit zu studieren. Frühere Beobachtungen des Sterns mit dem Namen SAO 244567 ließen einen dramatischen Anstieg seiner Temperatur erkennen. Neueste Daten belegen nun, dass sich der Stern in den vergangenen Jahrzehnten deutlich abgekühlt haben muss und damit in eine frühere Lebensphase wiedergeboren wurde. SAO 244567 ist bisher der einzige wiedergeborene Stern, der sowohl während der Aufheizungs- als auch der Abkühlungsphase beobachtet wurde. Die Studienergebnisse werden nun in den Monthly Notices of the Royal Astronomical Society publiziert. Neben Professor Klaus Werner und Ii. Khabmv Yntsc robxevj tgnh voc Khheerfqxkj ybp Laosdf Tj.
