Giants Like Jupiter May Have Formed In The Gas Disk Of Young Stars
2013-03-06 06:18:35

Lawrence LeBlond for redOrbit.com - Your Universe Online New research from Carnegie Institution for Science looks at how gas giants similar to Jupiter and Saturn formed and evolved. Using theoretical modeling, lead researcher Alan Boss provides clues that gas giants may form in the presence of gas disks that surround stars in their infancy. The work was recently published in the Astrophysical Journal. By observing young stars that are surrounded by gas disks, Boss demonstrated that...

Herschel Space Observatory Running On Fumes
2013-03-05 15:58:38

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency said Tuesday that its Herschel Space Observatory is beginning to wrap up its mission. Famous for its ability to view the sky in the entire wavelength range from far-infrared to submillimeter, the space observatory is beginning to run out of its supply of liquid helium coolant. ESA says Herschel is running on its last fumes and will be running empty in the coming weeks. Herschel first launched on May 14,...

W. M. Keck Observatory The W. M. Keck Observatory has successfully completed a $4 million campaign that will give astronomers the most detailed Adaptive Optics images of the cosmos ever created by mankind. Furthermore, the campaign was funded entirely by private philanthropy. The Gordon and Betty Moore Foundation, the W. M. Keck Foundation and The Bob & Renee Parsons Foundation awarded three grants totaling $3.7 million to significantly upgrade the Keck II Laser Guide Star Adaptive...

Canadian Scientists To Launch World's Smallest Telescope Monday
2013-02-24 06:31:10

Lee Rannals for redOrbit.com — Your Universe Online The world's smallest space telescope will be launching on Monday, aiming to push the boundaries of astronomy. The telescope satellite was designed, assembled and deployed fast and relatively cheap, by the Space Flight Laboratory (SFL) of the University of Toronto Institute for Aerospace Studies (UTIAS). Each of the BRIght Target Explorer (BRITE) satellites weigh less than 15 pounds, and are part of a new mission demonstrating...

Death Valley Receives Gold Tier Dark Sky Label
2013-02-22 04:49:58

Lee Rannals for redOrbit.com - Your Universe Online International Dark-Sky Association (IDA) announced this week that Death Valley National Park is being designated as the largest International Dark Sky Park in the world. The association said that the park offers views similar to what could have been seen before the rise of cities, due to its seclusion from other towns. Death Valley earned a "Gold Tier" status from the sky pollution watchdog, a status awarded to only those places...

Mars' Moons Vs. Earth’s Moon
2013-02-18 09:19:35

Rayshell Clapper for redOrbit.com — Your Universe Online Earth has one moon, and it is considerably larger than Pluto. In fact, the relative size of Earth´s moon is quite massive compared to the moons of other planets. We have a fascination with our moon on many levels. But what if Earth had two moons as Mars does? According to NASA, unlike Earth´s moon, Mars moons are two of the smallest in the entire solar system. Mars moons also have proper names: Phobos and...

Light Pollution Sparks Early Sexual Maturity For City Birds
2013-02-14 08:09:41

Enid Burns for redOrbit.com — Your Universe Online The light that emanates from cities may be causing birds to mate earlier. That's according to a study conducted by Max Planck Institute for Ornithology in Radolfzell, Germany. The study found that nighttime light in urban areas causes birds and other animals to develop their reproductive systems earlier. In the study researchers at the Max Planck Institute studied European blackbirds (Turdus merula), to see how they develop in...

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...
