The number of photons emitted into space is 4 followed by 84 zeroes. Now, that a moment to wrap that figure around your head.
What is being seen is that the universe is expanding faster nearby than we would expect based on more distant measurements.
We’ve learned a lot about the early universe.
It was floating around where we estimated it would be.
The Universe is flat, according to modern research. But what does that mean?
We may have dramatically underestimated what lies in the Universe.
Seeing is believing.
Zoom out far enough, and the Universe is a pretty homogenous place.
The European Space Agency’s Planck satellite has revealed some information which may force us to rethink the evolution of the early Universe.
Astronomers working with the Hubble telescope have discovered that the Universe is expanding 5-9% faster than expected, and this is intriguing.
Scientists have completed the most precise measurement of the Universe’s rate of expansion to date; but the result just isn’t compatible with speed calculations from remanent Big Bang radiation. Should the former results be confirmed by independent techniques, we might very well have to rewrite the laws of cosmology as we know them.
Don’t you just love it when art and science get together? Here, artist Pablo Carlos Budassi managed what seems impossible: representing the entire Universe in one picture. Using lots and lots of telescope, satellite images and photos snapped from NASA’s rovers, he painstakingly stitched many of the prominent features in the known Universe. He started from our solar system and then moved on in
NASA’s Hubble Space Telescope and the Spitzer Space Telescope jointly used their instruments to identify the oldest galaxy yet seen. Dubbed EGS8p7, this unusually luminous galaxy was formed just 600 million years after the Big Bang. When you peer that far into space and time, you’re bound to find some freaky stuff. EGS8p7 did no disappoint. Already, the 13.2 billion-year-old galaxy is raising questions about how we think the Universe evolved during its infancy.
Astronomers have discovered the oldest known stars lurking in a super-luminous galaxy – they may very well be among the very first objects that formed in the history of the Universe.
A team of astronomers from Yale and the University of California-Santa Cruz have looked back in time, discovering a galaxy that was formed when the Universe was only 5% of its current age. This is now the farthest, and youngest galaxy known to date.
Many people change a lot after their youth… and so to did our Universe. Nowadays, galaxies contain both dust and gas, but back in the early Big-Bang days, the earliest galaxies had no dust, only gas. Now, a team of astronomers has discovered a very young galaxy with lots of dust – the equivalent of a white-bearded young man.
Climate change is a threat to all life and vegetation here on Earth, but some places are worse off than others. Take Mongolia for instance. Over the past 30 years, a quarter of the country’s surface has turned into a desert, while 850 lakes and 2,000 rivers have dried out. This rapid desertification has severely disrupted habitats, making it very difficult for both man and beast to adapt. Even to this day, 25% of Mongolians living in the country are thought to be nomadic, still holding on to ancient traditions from the times when the great Khans swept the world and made it tremble, from Beijing to Rome. In the face of such diversity, the Mongolian people risk losing their heritage and way of life, as they’ve come to know it for thousands of years.
A newly published study has revealed that dark matter is being swallowed up by dark energy, offering valuable data not only about the nature and structure of these mysterious entities, but also about the future of the Universe. Dark Matter and Dark Energy In case you’re wondering, dark matter and dark energy are not Star Trek concepts – they’re real forms
The Illustris project took 5 years of software development and 3 months running on 8000 processors – but it sure was worth it – the result is truly monumental! Now, researchers finally have an accurate model of the development of the universe, which even though is rough around some edges, still blends in well with today’s accepted science, and even makes
A new map of a slice of the Universe was recently released by BOSS – Baryon Oscillation Spectroscopic Survey – and it’s the most accurate and comprehensive one so far. The map plots the location of some 1.2 million galaxies with an astonishing accuracy of 99%, nothing short of spectacular – remember, each of these objects is trillions of miles
