April Flowers for redOrbit.com - Your Universe Online Without understanding the internal structure in detail, it is still possible for scientists to learn a tremendous amount about neutron stars and quark stars, according to a new study from researchers at Montana State University. "The stars could be the softest or the hardest in their kind, and it wouldn't matter," said Nico Yunes, assistant professor in MSU's Department of Physics. Yunes and his colleague, postdoctoral scholar Kent...

Monstrous Stellar Collisions Not Expected To Occur Anytime Soon
2013-07-11 14:32:31

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists from the Astronomical Observatory of the Faculty of Physics at the University of Warsaw say the next collision of monstrous stars will not occur until billions of years from now. Three years ago, scientists discovered that the Magellanic Clouds host gigantic stars with between 200 and 300 times the solar mass  of our own Sun. Before then, astronomers believed that the biggest stars in the Universe did not...

Astronomers Use The Very Long Baseline Array To Set New Record
2013-06-13 14:46:36

ASTRON An international team of scientists led by astronomer Adam Deller (ASTRON) have used the Very Long Baseline Array (VLBA) to set a new distance accuracy record, pegging a pulsar called PSR J2222-0137 at 871.4 light-years from Earth. They did this by observing the object over a two-year period to detect its parallax, the slight shift in apparent position against background objects when viewed from opposite ends of Earth's orbit around the Sun. With an uncertainty less than four...

Heart Of Space Mission LISA Pathfinder Successfully Tested, Ready For Launch
2013-06-05 14:13:03

Max Planck Institute for Gravitational Physics The optical bench of the LISA Pathfinder (LPF) mission passed with flying colors extensive testing at the Institute for Gravitational Research (IGR) at the University of Glasgow. IGR scientists assured that the high-precision measurement system is ready to survive tremendous forces up to 35 g (35 times the gravitational acceleration on Earth) during rocket launch. “With the successful tests we reached an important milestone. The...

Detecting Elusive Gravity Waves From The Other End Of The Cosmos
2013-05-18 05:59:14

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Exchange of electromagnetic energy is fairly well understood. The force carrier, the photon, is readily detectable and manipulated, making the physics of electromagnetic radiation easy to study. By contrast, gravitational exchanges pose a much greater challenge. This arises, at least in part, because the gravitational force is so much weaker than that of electricity and magnetism. Also, the force carrier itself, the...

Millis, Ph.D. for redOrbit.com — Your Universe Online Click here to stream the “Supermassive Black Holes” podcast (Or right-click on the above link to download the file to your computer) Only a couple decades ago, the mere idea of supermassive black holes — those that are millions or billions of times more massive than our sun — seemed unthinkable to most astronomers. Now, however, we believe that these enormous objects lie at the center of nearly...

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Click here to stream "Facts About Black Holes — Separating Myth From Reality" (Or right-click on the above link to download the file to your computer) When most people think of a black hole, they tend to envision it as sort of cosmic vacuum cleaner, slowly sucking in and devouring everything in its vicinity. But are black holes really like this? And what would happen if you fell into a black hole? What about a...

They are swallowers of light, destroyers of stars and the engines that drive our galaxies. Some believe they could even hold the key to interstellar travel and may perhaps...

Atom Optics To Predict Gravitational Waves
2012-10-19 08:33:13

[ Watch the Video: Atomic Interferometer To Predict Gravitational Waves ] April Flowers for redOrbit.com - Your Universe Online NASA is pursuing a pioneering technology capable of atomic-level precision to detect gravitational waves or ripples in space-time caused by cataclysmic events, including the Big Bang itself. Researchers at NASA's Goddard Space Flight Center, AOSense, Inc and Stanford University have been awarded funding under NASA's Innovative Advanced Concepts (NIAC)...

Merging Black Holes Could Reveal Their Flashy Secrets
2012-09-29 08:09:37

[ Watch the Video: Black Holes Crash, Merge in New Simulations ] April Flowers for redOrbit.com - Your Universe Online Einstein predicted gravitational waves almost 100 years ago. According to his theory, whenever massive objects interact, they produce distortions in the very fabric of space and time that ripple outward across the universe at the speed of light. Modern astronomers have found indirect evidence of these waves, but so far they have eluded direct detection. Greater...

Word of the Day
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
