If the
light from a distant galaxy reaches us having passed through a cluster of say, four stars, she wondered, then how many images might we see?
Without the influence of a force like dark energy, the lines on this data chart,
taken from distant galaxies, would be nearly perfect circles.
The best way to work out where the dark matter lies is through gravitational lensing — the distortion of the Universe's fabric by gravity, which deflects the light
coming from distant galaxies far beyond the dark matter.
The light
waves from distant galaxies are stretched and reddened by the expansion of the universe, and this redshift is proportional to a galaxy's distance.
«Quantum foam» — grainy bumps in the fabric of space - time — might explain why light
from a distant galaxy arrived four minutes later than expected, offering clues about the real nature of gravity
New research by Harvard astronomers Peter Williams and Edo Berger shows that the radio emission believed to be an afterglow actually
originated from a distant galaxy's core and was unassociated with the fast radio burst.
But the force should also change the extent to which the cosmic microwave background (CMB), relic radiation from the big bang, is warped, or «lensed», by the
gravity from distant galaxies and dark matter.
With the increases in technology and astronomical know - how since then, a bounty of new objects may await discovery by WISE,
from distant galaxies whose optical light is dwarfed by their infrared output to failed stars known as brown dwarfs, some of which may be closer to Earth than the star Proxima Centauri, the sun's nearest known neighbor.
THE discovery of powerful galactic «winds», blowing
outwards from distant galaxies, could solve a mystery which has long baffled astronomers: why elements heavier than helium are found in the space between galaxies.
When you see Jupiter shining in the night sky, for example, you're looking about an hour back in time, whereas the light
from distant galaxies captured by telescopes today was emitted millions of years ago.
This is a subtle variant of weak gravitational lensing, in which the light
emitted from distant galaxies is slightly warped by the gravitational effect of large amounts of matter, such as galaxy clusters.
Now Andrew Gould and Jens Villumsen of Ohio State University in Columbus argue that the gravity of nearby galaxy clusters should distort the light
from distant galaxies in a way that depends on W.
Tantalizingly, just weeks before The Matrix came out in 1999, astronomers analyzing the light
from distant galaxies published hints that the universe's «constants» might not be so constant.
When some of those curves are projected back in time, the speed of light becomes so fast that light
from distant galaxies conceivably could have reached Earth in several thousand years.
Since we were measuring the dimming of blue light
from these distant galaxies caused by the foreground gas, the thin atmosphere at the summit of Mauna Kea allowed more of this blue light to reach the telescope and be measured by the highly sensitive detectors of the LRIS spectrograph.
It can be difficult to interpret the distortions that occur as light
from distant galaxies becomes magnified and bent by the vast mass of the Frontier Fields» galactic clusters.
GLAST is in part a follow - up to CGRO, which found high - energy
radiation from distant galaxies believed to contain supermassive black holes — up to a billion times more massive than the sun.
As it turns out, Jupiter's actually entitled to inherit Earth, and is informed of that good fortune by Caine Wise (Channing Tatum), a hunky
emissary from a distant galaxy.
Staring at a small patch of sky for more than 50 hours with the ultra-sensitive Karl G. Jansky Very Large Array (VLA), astronomers have for the first time identified discrete sources that account for nearly all the radio waves
coming from distant galaxies.
Light
from distant galaxies passing through those regions also gets warped, making the galaxies appear streaked and smeared in telescope images, a technique known as weak gravitational lensing.
For that price, the center got seven high - power lasers, trees illuminated with fiber optics, 5,000 - watt Xenon slide projectors, three 60 - foot circular screens suspended from the ceiling, a 30 - foot - diameter hydraulic sphere that seems to float 80 feet above an ice rink, a custom soundtrack, and a show put on by a group of Big Top performers claiming to have
traveled from a distant galaxy to perform in the mall.
They took advantage of a helping hand from nature, too: an effect known as gravitational lensing, predicted by Einstein's general theory of relativity, where
light from a distant galaxy is distorted by the gravitational effect of a nearer foreground galaxy, which acts like a lens and amplifies the brightness of the faint target.
If the expansion continues to accelerate, then in 100 billion years, the gap between galaxies will be growing so fast that light
from distant galaxies will no longer reach us.
This is how we see light
from distant galaxies — they are, relativistically speaking, billions of years old — but thanks to God's chronoton singularity, we are only a few thousand years old.
MAGNIFYING THE COSMOS The light
from a distant galaxy (lower right) is warped by the gravity of a closer, massive galaxy (bright blur in center).
Hubble found that the redder the light
from distant galaxies, the faster those galaxies were speeding away.
The light we see from our Sun takes just eight minutes to reach us, while the light
from distant galaxies we see via today's advanced telescopes travels for billions of years before it reaches us — so we're seeing what those galaxies looked like billions of years ago.
Billions of years ago, a heatwave struck the universe, leaving its imprint in the light
from distant galaxies.
From distant galaxies to deep inside your cells, and a dinosaur's breath to your kitchen stove, join us for seven of the most surprising voyages in the universe
GALACTIC QUARTET The way invisible dark matter warped the light
from distant galaxies, shown here as the swirl of material surrounding four giant galaxies in cluster Abell 3827 (seen in this Hubble Space Telescope photograph), suggested that dark matter can separate from stars when galaxies collide.
The expansion of the universe causes the light
from distant galaxies to be stretched or reddened with increasing distance.
