Der brit. Astronom Fred Hoyle war ein entschiedener Gegner der Urknalltheorie. In einer Radiosendung sprach er daher 1948 abschätzig vom „Big Bang“ und prägte damit ungewollt einen weltweit bekannten Begriff.

Eine visuelle Darstellung des Universums, die den Verlauf seiner Expansion von den Anfängen bis zur Gegenwart zeigt. Der Bildhintergrund ist schwarz, und es gibt verschiedene markierte Ereignisse und Zeitabschnitte. Diese sind durch Linien und Beschriftungen hervorgehoben, darunter die Hintergrundstrahlung, das dunkle Zeitalter, die Inflation, Quantenfluktuationen, die Entstehung der ersten Sterne und die beschleunigte Expansion infolge dunkler Energie. Die Zeitachse am unteren Rand zeigt den Verlauf von 13,7 Milliarden Jahren.

Discovery alert!

A spherical shell-like structure 1 billion light-years in diameter named Ho’oleilana is discovered in the distribution of relatively nearby galaxies. We posit this is the 1st observation of an individual Baryon Acoustic Oscillation (BAO).

An artist's view of Ho'oleilana. The three-dimensional shell enclosed by the Baryon Acoustic Oscillation is colorized in reddish/orange/brown color and enhanced to capture its content in terms of galaxies and to expose how it is encapsulated in the larger structure of the Cosmic Web. Galaxies are shown as luminous tiny specks. The Cosmic Web is represented as the blueish filamentary maze. This view also exposes the other structures discovered by the Cosmicflows research program: Laniakea our Home supercluster of galaxies; the South Pole Wall, a giant filament of the cosmic web that embraces the sourthernmost frontiers of Laniakea; the Dipole Repeller and the Cold Spot Repeller, two underdense regions presumably associated to two giant cosmic voids.

More evidence that water -- massive amounts of water -- have been present in the universe since shortly after the Big Bang.
All it took was hydrogen and oxygen, among the earliest elements created.
