Experiments by British scientists could reveal the make-up of the universe, the University of Liverpool said Thursday. The examinations will become part of the Advanced Gamma Tracking Array experiment, which seeks to create a so-called fingerprint of the inside of the atomic nucleus to help scientists understand the universe's structure, including humans and stars, the university said in a release. Scientists will analyze particle interactions that produce gamma rays, the university said, and...

On Monday, European Space Agency Director-General Jean-Jacques Dordain addressed the historic significance of the Apollo 11 mission to the Moon on the 40th anniversary of man's first footsteps onto the planet. "Back then, it meant that US technology was stronger than Soviet technology, because it was the US flag that was planted on the Moon," he said. "But today, I think we can see this in a totally different light. The fact that it was a US flag is no longer what matters most." "I think the...

We live in a hierarchical Universe where small structures join into larger ones. Earth is a planet in our Solar System, the Solar System resides in the Milky Way Galaxy, and galaxies combine into groups and clusters. Clusters are the largest structures in the Universe, but sadly our knowledge of them is not proportional to their size. Researchers have long known that the gas in the centers of some galaxy clusters is rapidly cooling and condensing, but were puzzled why this condensed gas did...

NEW YORK, June 25 /PRNewswire/ -- How does one distill 15 billion years of history -- the approximate time it took to make those crafty intelligent animals commonly known as Homo sapiens -- into a manuscript of roughly 400 pages in length? Like any journey, "Myths and Realities" starts at the beginning. John Whedbee's "Myths and Realities" (published by iUniverse) is an amazing discourse on the origin and nature of the human animal, offering an insightful view and discussion of mankind's...

Astronomers using the Science and Technology Facilities Council's (STFC) William Herschel Telescope (WHT) on La Palma have confirmed an effective way to search the atmospheres of planets for signs of life, vastly improving our chances of finding alien life outside our solar system. The team from the Instituto de Astrofisica de Canarias (IAC) used the WHT and the Nordic Optical Telescope (NOT) to gather information about the chemical composition of the Earth's atmosphere from sunlight that has...

Gamma-ray bursts, with their ability to pierce through gas and dust to shine brightly across the universe, are revealing areas of intense star formation and stellar death where astronomers have been unable to look - the dusty corners of otherwise dust-free galaxies.The conclusion comes from a survey of "dark" gamma-ray bursts - bright in gamma- and X-ray emissions, but with little or no visible light - reported today (Monday, June 8) at a meeting of the American Astronomical Society in...

Ground crews at Europe's Spaceport in French Guiana celebrated the successful tandem launch of the Herschel and Planck satellites aboard an Ariane 5 ECA heavy rocket on Thursday.The rocket, carrying the payload of the two scientific space observatories, left the launch center in Kourou on the northeast coast of South America at 10.12 am (1312 GMT).The satellites established their first contact with Earth about 10 minutes after the launch and are expected to separate from the rocket in order...

A spectrograph destined for the Hubble Telescope will look back several billion years and help reconstruct the early universe, scientists in Colorado said. The $70 million Cosmic Origin Spectrograph is to be carried to the Hubble aboard the shuttle Atlantis on its May 11 launch from the Kennedy Space Center in Florida, said James Green, a scientist at the University of Colorado in Boulder. The spectrograph -- the size of a telephone booth -- was built by the university and its industrial...

It sounds like the plot of a sci-fi movie: rogue black holes roaming our galaxy, threatening to swallow anything that gets too close. In fact, new calculations by Ryan O'Leary and Avi Loeb (Harvard-Smithsonian Center for Astrophysics) suggest that hundreds of massive black holes, left over from the galaxy-building days of the early universe, may wander the Milky Way. Good news, however: Earth is safe. The closest rogue black hole should reside thousands of light-years away. Astronomers are...

Researchers at North Carolina State University have used a mathematical model that allows them to get a clearer picture of the galaxy's youngest supernova remnant by correcting for the distortions caused by cosmic dust. Their new data provides evidence that this remnant is from a type Ia supernova - the explosion of a white dwarf star - and raises questions about the ways in which magnetic fields affect the generation of the remnant's cosmic ray particles. NC State physicists Dr. Stephen...

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Xenobiology -- Xenobiology (or exobiology, or astrobiology) is the term for a speculative field within biology which considers the possibility of, and possible nature of, extraterrestrial life. It also necessarily includes the concept of artificial life, since any life form might naturally evolve elsewhere, could conceivably come out of a laboratory using a future technology. It might be difficult to tell whether a truly strange life form had in fact arisen in space, or was designed much...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
