Astronomers Find Infant Solar System
2012-12-05 14:16:15

Lee Rannals for redOrbit.com - Your Universe Online The youngest still-forming solar system ever seen has been discovered by astronomers and reported about in the journal Nature. Astronomers found an infant star surrounded by a swirling disk of dust and gas more than 450 light-years from Earth in the constellation Taurus. The star has about one-fifth the mass of the Sun, but the scientists say it will likely pull in material from its surroundings to eventually match the Sun's mass....

European Southern Observatory (ESO) On 13 March 2013 the Atacama Large Millimeter/submillimeter Array (ALMA), the largest ground-based astronomical project in the world, will be inaugurated, celebrating ALMA´s transition from a construction project to a fully fledged observatory and marking the milestone of all the major systems of the observatory being operational. More than 50 of ALMA´s antennas will be in operation, and all 66 will be fully assembled. The inauguration ceremony...

Brown Dwarf Stars Can Grow Rocky Planets

Lee Rannals for redOrbit.com - Your Universe Online - Video 1 | Video 2 | Video 3 Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that the outer region of a dusty disc encircling a brown dwarf contains solid grains like those found in denser discs of newborn stars. The find challenges theories of how rock, Earth-scale planets form, suggesting the planets may be more common in the Universe than expected. Scientists believe rocky planets form...

Final US Antenna Dishes For ALMA Delivered
2012-11-21 05:07:52

April Flowers for redOrbit.com - Your Universe Online It has taken more than a decade of design and construction, but North America has finally delivered the last of 25 antenna dishes, marking an important milestone in the construction of an observatory astronomers are using to open up a "final frontier" of the spectrum of visible light to exploration. The dishes are 12-meters in diameter, and comprise the North American share of antennas for the international ALMA telescope. Stretching...

Star Stream Serves As Light Snack For Growing Milky Way
2012-10-27 05:56:42

redOrbit Staff & Wire Reports - Your Universe Online The Milky Way apparently has one voracious appetite, as researchers from a prominent American university have discovered our home galaxy slowly consuming the remnants of an ancient star cluster. Astronomers from Yale University used the Sloan Digital Sky Survey to locate a stream of stars being slowly ingested by the galaxy. While researchers have previously discovered evidence that the Milky Way has gobbled up dwarf galaxies,...

Stars Living On The Edge
2012-10-25 04:37:37

April Flowers for redOrbit.com - Your Universe Online A mysterious infrared glow seen across the entire sky comes from isolated stars beyond the edges of galaxies, according to a new study using data from NASA's Spitzer Space Telescope. The study, published in the journal Nature, suggests that these stars once belonged to the galaxies they edge up to, but were stripped away into the relatively empty space outside during violent galaxy mergers. Astronomers have disagreed for a long time...

Distant Quasar Shows No Sign Of Feeding On Galaxy Of Stars
2012-10-24 12:05:36

Lee Rannals for redOrbit.com — Your Universe Online While looking at one of the most distant quasars in the universe, astronomers were surprised to not see an underlying host galaxy of stars feeding it. NASA said the best explanation is that the galaxy is shrouded in so much dust that the stars are completely hidden everywhere. As stars aged and burned out in the early universe, they filled interstellar space with dust as they lost their atmosphere. The quasar dates back to an...

Atom Optics To Predict Gravitational Waves

[ 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)...

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...
