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...

Earth To Mars, Just How Far Is It?
2013-02-11 08:41:26

Alan McStravick for redOrbit.com - Your Universe Online If you´ve ever had an inquisitive child ask you how far Mars is from Earth and you were unsure how to answer then, you are not alone. On their individual courses around our Sun, Mars and Earth follow an elliptical orbit. Imagine two race cars traveling on two different tracks at differing speeds. This analogy helps you visualize how sometimes these two planets are close together while at other times they are, quite literally,...

NASA Constructs Lobster Eye Imager

April Flowers for redOrbit.com - Your Universe Online To study charge exchange, a poorly understood phenomenon that occurs when the solar wind collides with Earth's exosphere and neutral gas in interplanetary space, three NASA scientists teamed up to develop and demonstrate NASA's first wide-field-of-view soft X-ray camera. It is rare to have researchers from such diverse disciplines as heliophysics, astrophysics and planetary science teaming up, but that's exactly what happened at...

2013-01-19 07:45:06

Lawrence LeBlond for redOrbit.com - Your Universe Online Update: January 19, 2013 On Monday evening, astronomers (both amateurs and pros) across the country will be looking up to the skies to witness the super close dance between Jupiter and the Moon. Slooh Space Camera will also be there broadcasting live feeds of the event, giving everyone a shot at seeing the chance encounter. The waxing gibbous moon will appear about one degree south of Jupiter on Monday night, January 21. This...

Green Light For ALMA Early Science Cycle 1
2013-01-10 11:56:58

European Southern Observatory (ESO) ALMA (the Atacama Large Millimeter/submillimeter Array) has begun a new and more advanced phase of science observations. This phase is known as Early Science Cycle 1, and will last until October 2013. The telescope´s power has been greatly increased: it will make observations with more antennas, spread over a greater distance, than ever before, and will use antennas from the Atacama Compact Array (ACA) for the first time. Although ALMA is still...

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...
