J Richard Gott leads a journey through the history of our understanding of the Universe’s structure, and explains the ‘cosmic web’: the idea that our Universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies.

J Richard Gott was among the first cosmologists to propose that the structure of our Universe is like a sponge made up of clusters of galaxies intricately connected by filaments of galaxies – a magnificent structure now called the 'cosmic web'. In this talk he shows how ambitious telescope surveys such as the Sloan Digital Sky Survey are transforming our understanding of the cosmos, and how the cosmic web holds vital clues to the origins of the universe and the next trillion years that lie ahead.

J Richard Gott is Emeritus Professor of Astrophysical Sciences at Princeton University and is noted for his contributions to cosmology and general relativity.

 Evo i galerije najboljih slika koje je Kasini slikao tokom svoje misije. RIP Kasini

Sutra u 16h, ESO (European Southern Observatory, ne mešati sa ESA - European Space Agency) najavila konferenciju za štampu "to present groundbreaking observations of an astronomical phenomenon that has never been witnessed before."

 

Silno su tajnoviti, kod prijavljivanja medija za praćenje događaja, potpisuje se "embargo, details of which will be provided after registration, and not to publish or discuss any of the material presented before the start of the conference on 16 October 2017 at 16:00 CEST.".

 

Tko će dočekati!

For the first time, experiments have seen both light and gravitational waves released by a single celestial crash.

ESO Observations Show First Interstellar Asteroid is Like Nothing Seen Before
 

“This unusually large variation in brightness means that the object is highly elongated: about ten times as long as it is wide, with a complex, convoluted shape," says lead author Karen Meech of the Institute for Astronomy in Hawaii. `Oumuamua's length stretches about 400 meters, and we see the change in brightness as it spins on its axis every 7.3 hours. No known asteroid or comet in the solar system is so elongated, with the longest stretching only about three times longer than they are wide.
 
"We also found that it has a dark red color, similar to objects in the outer solar system, and confirmed that it is completely inert, without the faintest hint of dust around it," says Meech. The dark red color is a result of millions of years of irradiation from cosmic rays, and it suggests that the object is incredibly dense and rocky, or possibly high in metal content. The lack of activity or expelled debris as `Oumuamua made its close pass to the sun in September suggests the object lacks significant water or ice, classifying it as an asteroid rather than a comet as originally suggested.

Koliko je ovo zastrasujuce (u pozitivnom smislu)! Brrrrrrr!
