NASA Many scientists believe we are not alone in the universe. It's probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone -- just as it did here on planet Earth. This basic question about our place in the Universe is one that may be answered by scientific investigations. What are the next steps to finding life elsewhere? Experts from NASA and its partner institutions addressed this question on Monday, July 14, at...

supermoon summer
2014-07-12 06:22:37

April Flowers for redOrbit.com - Your Universe Online So-called supermoons are not a new phenomenon. However, the supermoon of July 2013 made headlines around the world, prompting a multitude of people to get out under the night sky to see it. The supermoon is approximately 14 percent larger and 30 percent brighter than a "regular" full moon. If the one supermoon of last summer caused such a stir, what will the three this summer cause? All three full moons this summer — July 12,...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online All across the Universe high-energy charged particles – mostly protons, electrons, and hydrogen nuclei, though heavier nuclei also exist – are found racing in all directions. The source of these particles, collectively called cosmic rays, is masked by the interstellar magnetic field that bends their paths, making them nearly impossible to directly trace. Much progress has been made in narrowing down their origin in recent...

NASA's James Webb Space Telescope Backplane Testing Complete
2014-07-09 03:55:45

NASA NASA's James Webb Space Telescope has reached another development milestone with the completion of static load testing of its primary mirror backplane support structure (PMBSS) moving the telescope one step closer to its 2018 launch. The PMBSS is the stable platform that holds the telescope's science instruments and the 18 beryllium mirror-segments that form the 21-foot-diameter primary mirror nearly motionless while the telescope peers into deep space. The primary mirror is the...

HESS-II telescope
2014-07-05 05:47:46

CNRS (Délégation Paris Michel-Ange) The HESS-II (High Energy Stereoscopic System) telescope in Namibia has detected gamma rays of only 30 Giga electron volts (GeV) from the Vela pulsar. This is the first pulsar to be detected by HESS and the second - after Crab in 2011 - to be spotted by ground-based gamma ray telescopes. These results have been obtained by the HESS collaboration involving the CNRS and CEA. The HESS experiment in Namibia, which was upgraded in 2012, now boasts a fifth...

European Space Agency Selects Athena Advanced Telescope For Study Of High-Energy Astrophysics
2014-06-27 09:41:59

Gerard LeBlond for redOrbit.com - Your Universe Online The European Space Agency (ESA) is in the process of launching a second “Large-class” mission to explore the universe for high-energy astrophysics and selected the Athena advanced telescope for the task. The mission is scheduled for launch in 2028 to study the hot and energetic Universe as part of ESA’s Cosmic Vision 2015 to 2025 plan. Athena is a large X-ray telescope combined with state-of-the-art scientific instruments...

General Dynamics-built radio telescope antennas give scientists a microscopic view of the universe that is thousands of light years away. NEWTON, N.C., June 25, 2014 /PRNewswire/ -- General Dynamics SATCOM Technologies, a part of General Dynamics C4 Systems, will build and install a 100-ton, 12-meter (40-foot), submillimeter-wavelength radio telescope antenna for the new Large Latin American Millimeter Array (LLAMA) observatory. The LLAMA project is a joint venture between...

3D Map Details Dusty Structure Of The Milky Way
2014-06-23 03:19:28

Royal Astronomical Society A team of international astronomers has created a detailed three-dimensional map of the dusty structure of the Milky Way – the star-studded bright disc of our own galaxy – as seen from Earth’s northern hemisphere. The map will be presented by Prof Janet Drew of the University of Hertfordshire at the National Astronomy Meeting (NAM) 2014 in Portsmouth on Monday 23 June. Dust and gas, making up the Interstellar Medium (ISM), fill space between stars in...

Cosmic Ring
2014-06-13 05:47:06

Whitney Clavin, Jet Propulsion Laboratory The Herschel Space Observatory has uncovered a weird ring of dusty material while obtaining one of the sharpest scans to date of a huge cloud of gas and dust, called NGC 7538. The observations have revealed numerous clumps of material, a baker's dozen of which may evolve into the most powerful kinds of stars in the universe. Herschel is a European Space Agency mission with important NASA contributions. "We have looked at NGC 7538 with Herschel...

ALMA maser installation team

National Radio Astronomy Observatory Scientists recently upgraded the Atacama Large Millimeter/submillimeter Array (ALMA) by installing an ultraprecise atomic clock at ALMA’s Array Operations Site, home to the observatory’s supercomputing correlator. This upgrade will eventually allow ALMA to synchronize with a worldwide network of radio astronomy facilities collectively known as the Event Horizon Telescope (EHT). Once assembled, the EHT -- with ALMA as the largest and most...

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...
