"Иллюстрис" моделирует Вселенную Illustris Simulation of the Universe
12.05.2014

How did we get here? Click play, sit back, and watch. A new computer simulation of the evolution of the universe -- the largest and most sophisticated yet produced -- provides new insight into how galaxies formed and new perspectives into humanity's place in the universe.



Очень далекое скопление галактик A Cluster Too Far
8.09.1998

Why is this galaxy cluster so red? Nearby clusters have galaxies with colors that are much more yellow and blue. A leading explanation is that this cluster of galaxies lies so far across our universe (z~1) that cosmological time dilation significantly reddens the light.



Далекая судьба A Distant Destiny
13.01.1998

Watching galaxies recede, observational astronomers of the 20th century discovered an astounding fact - the Universe is expanding. Will it continue to expand forever? The speed of light is finite so looking into the distant Universe is equivalent to looking at the distant past.



M15: огромное шаровое скопление M15: A Great Globular Cluster
26.07.1995

A globular cluster is a system of about one million stars that together orbit a galaxy. One of the brightest globular clusters in our Milky Way galaxy is the pictured M15, the fifteenth object on Messier's list of diffuse objects on our sky.



Космическое инфракрасное фоновое излучение The Cosmic Infrared Background
5.02.2002

What cosmic wallpaper is on the sky? The answer depends on the type of light considered, and for some wavelengths, all the cluttering material in the foreground makes it still unknown. Recently, however...



Карта реликтового излучения от "Планка" Planck Maps the Microwave Background
21.07.2018

What is our universe made of? To help find out, ESA launched the Planck satellite from 2009 to 2013 to map, in unprecedented detail, slight temperature differences on the oldest optical surface known -- the background sky when our universe first became transparent to light.



Начало скоплений The Dawn of the Clusters
14.01.1996

What did the universe look like near the beginning? This exciting photo by the Hubble Space Telescope is one of the deepest ever taken, and shows galaxies as far away as ever before photographed. The universe back then - when only one third of its present age - was a strange and violent place.



Барионные акустические осцилляции по данным обзора SDSS III Baryon Acoustic Oscillations from SDSS III
20.01.2014

How large do things appear when far away? When peering across the universe, the answer can actually tell us about its average gravitational history and hence its composition. Toward this goal, the Baryon Oscillation...



Космологические наблюдения за год A Year of Resolving Cosmology
30.12.2003

This year, humanity learned that the universe is 13.7 billion years old. Before this year, the universe's age was thought to be about 13 billion years, but really only constrained to be between about 12 billion and 15 billion years old.



Холодное пятно в реликтовом излучении The CMB Cold Spot
20.03.2011

How could part of the early universe be so cold? No one is sure, and many astronomers now think that the CMB Cold Spot on the cosmic microwave background (CMB) radiation is not particularly noteworthy. As the early universe expanded and cooled, it suddenly and predictably became transparent.
