In March, NASA launched its Kepler telescope with the hopes of discovering an Earth-like planet that could be hospitable to extraterrestrial life. However, one team of scientists has gone as far to say that the orbiting telescope will likely discover habitable "exomoons" as well. Writing in the Monthly Notices of the Royal Astronomical Society, Dr David Kipping and colleagues of University College London created a detailed method that scientists would need to follow while looking for...

Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun's gravity, and their technique promises a major contribution to a frontier area of basic physics."Measuring the curvature of space caused by gravity is one of the most sensitive ways to learn how Einstein's theory of General Relativity relates to quantum physics. Uniting gravity theory with quantum theory is a major goal of 21st-Century physics,...

An international group of scientists says it has defined the energy density of gravitational waves created immediately after the birth of the universe. Gravitational waves that still ripple across the universe are believed to result from the Big Bang that created the universe more than 13 billion years ago. Albert Einstein predicted the existence of the waves in 1916, and the first evidence of their existence was reported in 1979. Scientists from the Laser Interferometer Gravitational-Wave...

On Wednesday, Aug. 19, 2009, the National Science Foundation (NSF) will host a live webcast featuring University of Minnesota Physicist Vuk Mandic, who is a lead author of an upcoming paper in the journal Nature that significantly advances scientific understanding of the early evolution of the universe. Mandic is cochair of the Stochastic Working Group of the LIGO (Laser Interferometer Gravitational-Wave Observatory) Scientific Collaboration (LSC). Founded in 1997, the LSC seeks to directly...

Device can instantly measure the mass of an individual moleculeUsing devices millionths of a meter in size, physicists at the California Institute of Technology (Caltech) have developed a technique to determine the mass of a single molecule, in real time.The mass of molecules is traditionally measured using mass spectrometry, in which samples consisting of tens of thousands of molecules are ionized, to produce charged versions of the molecules, or ions. Those ions are then directed into an...

Taller men are able to earn more money than their shorter counterparts simply because taller people are perceived to be more intelligent and powerful, this according to a study published in The Economic Record by Wiley-Blackwell.The study entitled "Does Size Matter in Australia?" uses newly available data from the Household, Income and Labor Dynamics in Australia (HILDA) survey to estimate the relationship between hourly wages and two aspects of body size: height and BMI.It finds that taller...

Isotopes, the atomic clues used to solve crimes, date ancient artifacts and identify chemicalsWhether it's the summer grass that tickles your feet or the red Bordeaux smacking on your palette, nearly every part of the world around you carries special chemical markers. These markers, called isotopes, can tell scientists where the molecules that compose a substance are from, where they traveled, and what happened to them along the way. But doing these analyses has been complex and costly. Now,...

In 1919, the Royal Astronomical Society (RAS) launched an expedition to the West African island of Príncipe, to observe a total solar eclipse and prove or disprove Einstein's General Theory of Relativity. Now, in a new RAS-funded expedition for the International Year of Astronomy (IYA 2009), scientists are back. Astronomers Professor Pedro Ferreira from the University of Oxford and Dr Richard Massey from the University of Edinburgh, along with Oxford anthropologist Dr Gisa...

Thousands to Pray for End to Abortion WASHINGTON, Jan. 16 /PRNewswire-USNewswire/ -- Thousands of Catholics will gather in the Basilica of the National Shrine of the Immaculate Conception to pray for an end to abortion at the National Prayer Vigil for Life Opening Mass at 7:00 p.m. on January 21, the eve of the 36th anniversary of Roe v. Wade, the 1973 Supreme Court decision legalizing abortion. Over 16,000 worshipers - many of them youth from schools around the nation - are expected to...

In a move that would have any astrophysicist scratching his head, the U.S. Defense Intelligence Agency (DIA) commissioned a report to assess whether gravitational waves could threaten national security. The JASON Defense Advisory Group was also asked to investigate other potential applications for high-frequency gravitational waves, such as imaging the Earth's core or uses in telecommunications. Gravitational waves are wrinkles in space-time caused by the movement of objects with...

Satellite -- A satellite is an object that orbits another object. With sufficient tangential velocity, the object does not collide with the primary object it orbits, but maintains a distance from that object as the rate at which it falls towards that object is similar to the rate that it travels away, thus the object orbits the primary object and becomes a satellite. In other words: gravitational force serves as the centripetal force needed to make the object circle the primary...

Gravitational Lens -- A gravitational lens is formed when the light from a very distant, bright object (such as a quasar) is "bent" around a massive object (such as a massive galaxy) between the bright object and the viewer. The process is known as gravitational lensing, and was one of the predictions made by Einstein's general relativity. Description In a gravitational lens, the gravity from the massive object bends light as a lens might. As a result, the path of the light from a...
