Life Delivered By Space Rocks?
2012-09-24 19:03:37

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have provided more evidence that life was delivered to Earth through collisions with objects like asteroids. Researchers presented a paper at the European Planetary Sciences Congress on Tuesday, showing microorganisms that crashed to Earth might have been what sparked life. The astronomers report under certain conditions there is a high probability that life came to Earth during the Solar System's infancy when...

Student Biology Investigations Stream Live From International Space Station
2012-09-11 15:22:20

Several young researchers were incredibly excited when the latest Japanese cargo ship arrived at the International Space Station, in late July. Along with the usual food, clothing, and science investigations, the spacecraft delivered the two global YouTube Space Lab winning entries. Dorothy Chen and Sara Ma (from Troy, Mich.) and Amr Mohamed (from Alexandria, Egypt) won this opportunity to do research in the orbiting laboratory's microgravity environment -- while attending high school....

Radiation From Sun’s Solar Whip Is Expected To Reach Earth Today
2012-09-04 07:45:16

Watch the Video: Filament Eruption August 31, 2012 Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists from NASA have discovered an enormous ℠solar whip´ on the surface of the Sun and have warned that radiation from the phenomenon is heading straight toward Earth, arriving on our doorstep sometime today. The stunning event was captured by NASA´s Solar Dynamics Observatory (SDO) and, according to a report from Mail Online´s Mark Prigg, video and...

Massive Winds Driven By Intense Star Formation
2012-08-22 05:30:05

April Flowers for redOrbit.com - Your Universe Online Fueled by an intense burst of star formation, fierce galactic winds may blow gas right out of massive galaxies, which in turn could shut down their ability to make new stars. A team of astronomers sifted through images and data from three telescopes to find 29 objects with outflowing winds measuring up to 2,500 kilometers per second, an order of magnitude faster than most observed galactic winds. "They're nearly blowing themselves...

La Silla Snaps Detailed Image Of The Pipe Nebula

Videos: Zooming in on the Dark Nebula Barnard 59 | Panning Across the Dark Nebula Barnard 59 Lee Rannals for redOrbit.com - Your Universe Online A new image of the Pipe Nebula has been taken using the Wide Field Imager at the European Space Observatory's La Silla Observatory. The Pipe Nebula is a vast dark cloud of interstellar dust, or a dark nebula, which is a type of nebula that consist of stars, but is so thick with dust that it blocks out the light. The dark nebula is...

Lee Rannals for redOrbit.com - Your Universe Online Scientists are warning that power grids, communications and satellites could be knocked out by a massive solar storm within the next two years. The sun will be reaching its peak in its 10-year solar activity cycle, putting the Earth at a greater risk from solar storms. During this peak, scientists say there is a heightened risk that a solar storm could knock out the communication systems that we rely on. "Governments are taking...

Solar Winds Affect Earth's Magnetosphere
2012-08-01 13:04:29

April Flowers for redOrbit.com — Your Universe Online Weather has always affected our lives, but we are increasingly reliant on technology that can be disrupted by space weather. Geomagnetic storms, which are major disturbances of the magnetosphere, cause high altitude flights to be rerouted, costing many thousands of dollars per flight; cause GPS errors of up to 151 feet; and affect the International Space Station and satellites. Geomagnetic storms and other space weather...

Solar Flare Captured By SDO
2012-07-31 13:47:29

Lee Rannals for redOrbit.com - Your Universe Online NASA's Solar Dynamics Observatory (Solar Dynamics Observatory) captured a mid-level solar flare on Saturday, showing us that the sun is getting prepped for its solar maximum. SDO witnessed the image on the active region of the sun named AR 1532 in the 131 Angstrom wavelength. This wavelength is typically colorized as teal, and is particularly good for catching flares, NASA said. Solar flares emit powerful bursts of radiation, which...

Coronal Mass Ejection Unlikely To Reach Earth
2012-07-21 04:31:52

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online A coronal mass ejection (CME) associated with a solar flare emitted early Thursday morning is unlikely to reach Earth, but it could affect one of the two Solar Terrestrial Relations Observatory (STEREO) satellites currently orbiting the sun, NASA officials posted on the agency's official website. According to the US space agency, the sun emitted a mid-level (M7.7) flare on July 19. The flare, which began at...

Stellar Astrophysics

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...

Planetary and Space Science
2012-05-28 10:21:45

Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...

Ring Current
2004-10-19 04:45:44

Ring Current -- A ring current is an electric current carried by charged particles trapped in a planet's magnetosphere. It is caused by the longitudinal drift of energetic (10-200 keV) particles. Earth's Ring Current Earth's ring current is responsible for geomagnetic storms. The ring current system consists of a band, at a distance of 3-5 RE(1), which lies in the equatorial plane and circulates clockwise around the Earth (when viewed from the north). The particles of this region...

Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...
