Если вы когда‑либо слышали о «величайшей ошибке Эйнштейна» — скорее всего, речь шла о космологической постоянной. Это был поправочный коэффициент, который Эйнштейн ввёл в свои урав...
Dark energy revived Einstein’s discarded cosmological constant and reshaped the leading model of the universe. In 1917, Albert Einstein had recently completed his general theory of...
This NASA Hubble Space Telescope image features a galaxy cluster, called CL0016+1609 or MACS J0018.5+1626, that is very bright at X-ray wavelengths and is one of the most extensive...
Modern astronomy relies not only on bigger telescopes and more sophisticated instruments, but upon computational power. Source
Modern cosmology rests on a simple assumption: if we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known...
The nature of dark energy brings to light one of the most powerful pieces of evidence for just how special our universe is to support life. Source
Astronomers have measured the ages of over a hundred and fifty thousand ancient stars scattered across our Galaxy, and found the oldest of them is just the age it should be if the...
The NASA/ESA Hubble Space Telescope is still going strong and delivering unbelievably beautiful deep-space images. The latest Hubble image shows globular cluster NGC 6723, sometime...
Using Hubble, astronomers have discovered that the only known "helium nova" in the Milky Way is riddling our galaxy with cosmic bullets travelling at 20 million mph.
Современная астрофизика столкнулась с крупнейшим кризисом за последние полвека: концепция, согласно которой темная энергия заставляет Вселенную расширяться с ускорением, может оказ...
The universe’s expansion makes cosmic distance far less intuitive than simply measuring how long light has traveled. An expanding universe makes distance harder to define because s...
For its first billion years the universe was lost in fog, a thick haze of hydrogen that swallowed light whole. Something burned it away, and astronomers have long wondered what. No...
A new study using data from NASA's Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has undergone a 500-million-year decline, with an even steeper dr...
Stars and galaxies make up much of the universe’s ordinary, observable matter. But for decades, scientists have wrestled with a cosmic conflict: There should be much more. Physici...
Two major mysteries in science, the nature of dark matter and the possible existence of higher dimensions, could be linked, new research suggests.
According to current understanding, the universe is expanding—and is doing so at an accelerating rate. This is believed to be caused by something called the cosmological constant,...
The massive globular star cluster Omega Centauri has puzzled astronomers for decades. It should be filled with black holes left behind by exploding stars, yet evidence for them is...
New observations from NASA’s James Webb Space Telescope deepen the mystery of a young but unexpectedly mature galaxy cluster in the early universe that challenges leading ideas abo...
The origin of spin in spiral and elliptical galaxies has posed a long-standing puzzle for astronomers. One idea, known as tidal torque theory, proposes that galaxies' spins are an...
Observations of a distant cluster of stars in our galaxy have resulted in a new class of objects that turn out to be galactic building blocks. Researchers used Hubble Space Telesc...
About 25 years ago, astrophysicists noticed that the universe’s expansion is accelerating. To account for this observation, physicists came up with a new type of energy – called da...
Imagine standing in the emptiest place the universe has to offer, a stretch of cosmic ocean so vast that light takes tens of millions of years to cross it, and yet still finding co...
