Door Opened For Solid State Physics By Berlin Researchers
2013-08-21 15:25:40

Helmholtz Association Laser processes observed with X-rays on a solid Without the currently available plethora of X-ray methods, basic research in the physical sciences would be unthinkable. The methods are used in solid state physics, in the analysis of biological structures, and even art historians have X-rays to thank for many new insights. Now, scientists at the Helmholtz Center Berlin (HZB) have identified yet another area of application. The team around Dr. Martin Beye and Prof....

ALMA Pics Dramatic Star Birth
2013-08-20 09:15:05

Lee Rannals for redOrbit.com - Your Universe Online Astronomers say they have obtained a close-up view of material streaming away from a newborn star. Using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope, a team of scientists was able to discover the jets coming off an object called Herbig-Haro 46/47 are even more energetic than previously believed. The new images also reveal a previously unknown jet pointing in an entirely different direction. The new images reveal...

Stratospheric Observatory For Infrared Astronomy In New Zealand

NASA NASA's SOFIA observatory program manager Eddie Zavala reflects on the myriad details of preparing for and then executing the flying observatory's first Southern Hemisphere mission in the summer of 2013. Fly 6,900 miles each way, deploy a cadre of flight and ground crew members along with an international science team for three weeks, and during that time fly three nights per week, 10 hours per flight, all while conducting world-class science. It’s a lot to imagine, and even...

Las Cumbres Obsevatory Astronomy Imager Captures First Light
2013-08-02 09:25:02

Las Cumbres Observatory Las Cumbres Observatory Global Telescope (LCOGT), with first lights at nine new 1-meter telescopes since April of 2012, achieved another critical milestone by capturing the first on-sky image with a production Sinistro camera. In development for over six years, the camera is arguably more important than the telescopes that will use them. "A telescope is really nothing more than a large camera lens," explained Joe Tufts, instrumentation scientist on the Sinistro...

Exploring Hidden Milky Way
2013-08-01 08:48:11

John P. Millis, PhD for redOrbit.com - Your Universe Online Understanding how the Milky Way formed is one of the central scientific questions in astronomy. However, given the scale and complexity of the galaxy, there is a lot to consider. One of the ways researchers have found to tell the story of our galaxy's history is to create a detailed stellar census, analyzing spectra of large numbers of stars. "A star's spectrum is a powerful tool for learning about the star - it tells us key...

Chandra Eyes An Eclipsing Planet
2013-07-30 04:21:13

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using NASA's Chandra observatory were able to witness an eclipsing planet for the first time. A team writing in The Astrophysical Journal said they used the X-ray observatory to detect the exoplanet passing in front of its parent star. "Thousands of planet candidates have been seen to transit in only optical light," said Katja Poppenhaeger of Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass., who led...

XMM-Newton's Dance Of The X-rays
2013-07-29 08:36:40

ESA Like car tail lights streaking through a busy city at night, this unique image records over a thousand movements made by ESA's XMM-Newton space telescope as it shifts its gaze from one X-ray object to another. Orbiting in space since 1999, XMM-Newton is studying high-energy phenomena in the Universe, such as black holes, neutron stars, pulsars and stellar winds. Even when moving from object to object, the space telescope collects data. These slews are represented by the bright...

Quasar Radiation Influences Galaxy Growth
2013-07-25 05:58:07

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists writing in The Astrophysical Journal have shed some new light on the universe's brightest objects - quasars. The team from Dartmouth University published details about discoveries based on 10 quasar observations. They wrote about the power of quasar radiation, which can reach out for many thousands of light years to the limits of the quasar's galaxy. Astrophysicists Ryan Hickox and Kevin Hainline and colleagues used...

This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...

Radio telescopes, used in tracking and collecting data from satellites and space probes, are a form of directional radio antenna used in radio astronomy. They operate on the radio frequency portion of the electromagnetic spectrum where they detect radio sources. Radio telescopes are large parabolic antennas used singly or in an array and are located far from major centers of population in order to avoid electromagnetic interference. Karl Guthe Jansky built the first radio antenna used to...

A telescope, designed to aid the observation of remote objects, collects some form of electromagnetic radiation (such as visible light). The Netherlands developed the first known practical telescope in the 17th century. The term "telescope" was termed in order to describe Galileo's instruments in 1611. However, Galileo was not the inventor of the telescope. It was Hans Lippershey, Zacharias Janssen, and Jacob Metius who are credited with the creation of the telescope. In 1668, Isaac Newton...

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...

The Reverend Thomas William Webb (December 14, 1807 "“ May 19, 1885) was a British astronomer and faithful clergyman. The lone son of a clergyman, the Rev. John Webb was raised and educated by his father in absence of his mother who died in Webb's early childhood. He travelled to Oxford to attend Magdalen College. Soon after, he was ordained a minister by the Anglican Church in 1829. In 1843, he married Henrietta Montague. Mrs. Webb died on September 7, 1884. Webb followed shortly...
