ESO Celebrates 50 Years Of Relationship With Chile
2013-11-11 06:31:56

ESO Today marks the 50th anniversary of the start of a very fruitful relationship between ESO and Chile that has allowed both European and Chilean astronomy to push the boundaries of science, technology and culture forward into the future. On 6 November 1963, the initial agreement between the European Southern Observatory (ESO) and the Government of Chile, the Convenio, was signed, enabling ESO to place its telescopes beneath the exceptionally clear Chilean skies. "The cooperation...

Superconductor Astronomy
2013-11-05 09:42:56

Brett Smith for redOrbit.com - Your Universe Online Having been commercially manufactured since the 1960s, semiconductors are the backbone of modern electronics. However, these materials are slowly being replaced by superconductors – particularly in the field of astrophysics. Superconductivity is essentially a quantum phenomenon that happens when certain materials are cooled to near absolute zero. This cooling eliminates electrical resistance and magnetic fields, allowing for the...

Study Provides Unprecedented Details On Ultrafast Processes In Diamond Nitrogen Vacancy Centers
2013-11-04 16:26:12

Lawrence Berkeley National Laboratory From supersensitive detections of magnetic fields to quantum information processing, the key to a number of highly promising advanced technologies may lie in one of the most common defects in diamonds. Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have taken an important step towards unlocking this key with the first ever detailed look at critical ultrafast processes in these...

University of Arizona Using ultra-fast laser pulses, researchers have made the first detailed observation of how energy travels through diamonds containing nitrogen-vacancy centers -- promising candidates for a variety of technological advances such as quantum computing A team of researchers led by University of Arizona assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds that contain nitrogen-vacancy centers – defects in...

Final Antenna Now Handed Over To The ALMA observatory
2013-10-01 08:46:38

ESO The final antenna for the Atacama Large Millimeter/submillimeter Array (ALMA) project has just been handed over to the ALMA Observatory. The 12-meter-diameter dish was manufactured by the European AEM Consortium and also marks the successful delivery of a total of 25 European antennas — the largest ESO contract so far. The antenna is the 66th and final antenna to be delivered to the observatory. North America has provided 25 12-metre antennas, while East Asia has delivered 16...

The prevalence of light may cause detrimental effects. (PRWEB) September 30, 2013 Many people have noticed how birds fly into buildings. What many may not know, however, is that one of the reasons for this is that bright lights can disorient and distract birds, diverting them from their course and can even make them fly into structures in an irrational way. Organizations worldwide are being established to address the prevalence of light pollution, which has exponentially grown in the last...

Cat's Paw Nebula Viewed In High Detail With New Instrument
2013-09-25 10:18:55

Lee Rannals for redOrbit.com - Your Universe Online A new, powerful viewing instrument installed on the Atacama Pathfinder Experiment (APEX) has already given astronomers a detailed view of the Cat's Paw Nebula. The ArTeMiS is a new wide-field submillimeter-wavelength camera that will further increase the depth and detail that APEX can observe. The new instrument's detector acts more like a CCD camera than the previous generation of detectors, which will allow it to map the sky faster...

Image Caption: NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light-years in diameter and approximately 60 million light-years distant. Credit: NASA/ESA/Wikipedia What is Astrophysics? For much of the modern age the term Astrophysics has been used synonymously with Astronomy. 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...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
