Latest Cosmology Stories
The European Space Agency's Euclid module under development in France will be helping to explore dark energy and dark matter in the universe.
Scientists have debated the merits of the anthropic principle – the notion that the universe is somehow fine-tuned for life, or vice versa – and its variants for decades. The search to understand the nature and evolution of the universe is what plagues the fields of cosmology and astrophysics.
Although he probably never expected a career in physics would warrant it, Stephen Hawking received a ‘rock star’ reception to his speaking engagement at the California Institute of Technology (Caltech) in Pasadena, California on Tuesday.
Using technologies contributed by NASA, the European Space Agency's (ESA) Planck space mission has provided the most accurate and detailed map made of the oldest light in the universe.
New Book is a Trove of Incisive Insights on the Evolution of the Universe QUEBEC (PRWEB) January 15, 2013 The Big Bang theory is the prevailing paradigm
Astronomers have reportedly discovered the largest known structure in the universe – a formation so massive it would take a vehicle that was moving at light speed roughly four billion light years to cross it.
In 1998 scientists measuring the expansion of the Universe made a startling discovery: the Universe is accelerating. Previously, researchers believed that the expansion of the Universe would eventually slow under the influence of gravity.
Penn State University scientists using techniques from modern physics have developed a new understanding of the earliest eras in the history of the universe.
The American Institute of Physics (AIP) has selected author Richard Panek as winner of this year’s AIP Science Communication Award in the Science Writing category for his book The 4% Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality.
A pair of University of California, Berkeley scientists have been awarded grants to aid in their study of advanced extraterrestrial civilizations and alternate universes.
Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

Sample Entry: Astronomy is the scientific study of stars, planets, comets, galaxies, and other phenomena that occur outside Earth's atmosphere (e.g. cosmic radiation). Astronomy deals with the evolution, physics, chemical makeup, meteorology, and motion of celestial objects, and also the formation of the universe. The word Astronomy comes from the Greek words astron (meaning "star") and nomos (meaning "law"). Astronomy is one of the oldest sciences. Since the dawn of man, people always...
Cosmology -- area of science that aims at a comprehensive theory of the structure and evolution of the entire physical universe. Modern Cosmological Theories Present models of the universe hold two fundamental premises: the cosmological principle and the dominant role of gravitation. Derived by Hubble, the cosmological principle holds that if a large enough sample of galaxies is considered, the universe looks the same from all positions and in all directions in space. The second point...
Quintessence (Dark Energy) -- Quintessence or dark energy is a hypothetical form of energy postulated to exist in order to explain observations of an accelerating universe. This energy would act like a vacuum pressure, pushing things apart. Other attempts to explain these recent observations involve a non-zero cosmological constant, which has the same effect. Indeed, sometimes quintessence is said to result in a non-zero cosmological constant, and conversely a non-zero cosmological...
Accelerating universe -- In the late 1990s, observations of type I supernova produced the unexpected result that the expansion of the universe appears to be accelerating. These observations appear more firm as new data has appeared. This means that the speed with which a distant galaxy recedes from us increases over time. If this trend continues, eventually we won't be able to see any other galaxies any more. This new theory of the end of the Universe has been called the Big Rip....
