By Siegfried, Tom One of the enduring strengths of Science News is its scope. Its pages are open to all fields of science and their subspecialties, to all the realms of human inquiry into the natural (and artificial) world, whether physical, biological or social.

Scientists predict that trillions of years into the future, the information that currently allows us to understand our universe will have disappeared over the visible horizon.

Scientists have traced the expansion history of the universe with unprecedented accuracy and sharpened our knowledge of what it might be that is causing the mysterious acceleration of the expansion of the universe.

Cool spaces in the cosmic microwave background -- thought to be the ³birthmarks' of galaxies and clusters of galaxies -- should be bigger than recently reported, according to a new analysis of satellite data by scientists at The University of Alabama in Huntsville (UAH).

The concept of time is self-evident. An hour consists of a certain number of minutes, a day of hours and a year of days. But we rarely think about the fundamental nature of time.

Astrophysicists have drawn up the largest map to date of the universe, confirming gravity's role in its formation and establishing an accurate way of measuring its expansion, according to studies presented at a meeting of the American Astronomical Society.

Astronomer Royal, Sir Martin Rees discusses the limits to our knowledge of what might have preceded the big bang. Everyone asks the question: what was 'there' the instant before everything came to be?, but the question may not go as deep as the answers it spawns.

THE BIG BANG by Simon Singh (Fourth Estate, Pounds 20) ROLL UP for the greatest story ever told! At last, science describes the creation of the universe! Well, not quite. On creation as most of us understand it, science is silent.

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. Credit: NASA/Wikipedia What is Cosmology? I once commented to an acquaintance that I was fascinated by the field of Cosmology, and mused that if I had more time, I...

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....
