MMS To Study Secrets Of Magnetic Reconnection
2014-05-16 03:36:18

Susan Hendrix, NASA In March 2015, NASA will launch four identical spacecraft to study how magnetic fields around Earth connect and disconnect, explosively releasing energy – a process known as magnetic reconnection. The Magnetospheric Multiscale, or MMS, mission will provide the first three-dimensional views of this fundamental process that can accelerate particles to nearly the speed of light. MMS uses Earth’s protective magnetic space environment, the magnetosphere, as a natural...

New Insight Into Formation Of Star Clusters Provided By NASA's Chandra X-ray Observatory
2014-05-16 03:44:41

[ Watch The Video: A Tour Of The Flame Nebula ] Harvard-Smithsonian Center for Astrophysics Stars are often born in clusters, in giant clouds of gas and dust. Astronomers have studied two star clusters using NASA's Chandra X-ray Observatory and infrared telescopes and the results show that the simplest ideas for the birth of these clusters cannot work. This composite image shows one of the clusters, NGC 2024, which is found in the center of the so-called Flame Nebula about 1,400...

Mars' Atmosphere Loss To Be Measured By NASA's MAVEN Orbiter
2014-05-15 10:47:48

Brett Smith for redOrbit.com - Your Universe Online When NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission arrives at its destination later this year, an instrument on board could help to determine why Mars has slowly lost much of its atmosphere and become the barren planet we see today. After MAVEN enters into an orbit above Mars, its Solar Wind Ion Analyzer (SWIA) will begin sampling the small electrically charged particles in and above the planet’s wispy atmosphere....

Testing Einstein's Theory Of Relativity Through Cosmic Microwave Measurements
2014-05-14 08:27:34

April Flowers for redOrbit.com - Your Universe Online What do you get when you combine polarized radiation with Einstein's theory of general relativity? According to a group of astrophysicists at UC San Diego, you just might get more accurate estimates for the mass of ghostly subatomic particles known as neutrinos. The study, published in Physical Review Letters, measures the distortions in polarized radiation from the early universe and demonstrates that these ancient microwaves can...

What Would Happen If Saturn Came Extremely Close To Earth?
2014-05-14 07:38:35

redOrbit Staff & Wire Reports - Your Universe Online While astronomers enjoyed the best view of Saturn this past weekend, an animator created a new video depicting what would happen if the people of Earth got an extreme close-up of the sixth planet from the Sun. According to Laurel Kornfeld of The Space Reporter, Saturn reached opposition on May 10, which means that it and the Earth were on opposite sides of the Sun. The ringed planet was also at its closest distance to our world...

Have Experts Finally Solved The Mystery Of Magnetars?
2014-05-14 06:55:50

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online When a massive star reaches the end of its life, it explodes in a brilliant supernova explosion. The remnant of the stellar core will usually form either a neutron star or a black hole. Occasionally, however, there emerges a third option: a magnetar. These exotic objects, share a lot in common with neutron stars. They are incredibly dense – second only to black holes in that regard – and spin very rapidly, though not...

Finding An Exoplanet That Takes 80,000 Earth Years To Orbit Its Sun
2014-05-14 05:40:33

Brett Smith for redOrbit.com - Your Universe Online Using observations from multiple observation facilities, an international team of astronomers has identified a very unusual planet that takes around 80,000 Earth years to orbit its sun. The planet, dubbed GU Psc b, was determined to be 2,000 times the distance between the Earth and the Sun from its own star – a new record for exoplanets. The team said they were able to detect this highly unusual planet by detecting the light coming...

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

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...

Tropic of Capricorn
2013-02-21 13:31:57

The Tropic of Capricorn, alternately called the Southern Tropic, is a marker of the most southerly latitude on the Earth at which the Sun can be directly overhead. This occurs at the December solstice, when the southern hemisphere is tilted towards the sun at its maximum degree. It is one of the five major circles of latitude that mark maps of the Earth. It presently lies 23 degrees 26’ 16’’ south of the Equator. Currently, the Tropic of Capricorn is drifting towards the north at...
