Lawrence LeBlond for redOrbit.com - Your Universe Online NASA’s Solar Dynamics Observatory (SDO) recorded a coronal mass ejection (CME) on Saturday April 20, 2013, at 2:54 a.m. EDT. That was only to be the first of three such events over the course of the weekend. CME’s, solar phenomena that send billions of tons of solar particles and radiation speeding through space at over 500 miles per second, have the potential to affect communication systems and electronics here and in orbit...

Lawrence LeBlond for redOrbit.com - Your Universe Online A powerful solar eruption occurred on the surface of the sun at 2:54 a.m. (EDT) this morning. The eruption, called a coronal mass ejection (CME), occurred on the Earth-facing side of the sun and may have released billions of tons of solar particles into space racing their way toward Earth, potentially making impact within three days. Once particles from this CME event hit Earth, electrical systems in orbit, in the sky and on...

Brett Smith for redOrbit.com - Your Universe Online Earlier this week the sun twice ejected large amounts of solar material during two coronal mass ejections (CMEs) in a 12-hour period, according to a NASA report. The CMEs are not expected to significantly impact Earth. The first CME began at 8:36 p.m. EDT on March 12, 2013. The solar material was directed toward three NASA spacecraft, Spitzer, Kepler and Epoxi. Two of the crafts, Spitzer and Kepler, are in an Earth-like orbit around...

From a news release by NASA, dated February 28, 2013, the Birth of a Planet was observed from Earth through the Hubble Telescope that possibly showed a proto planet being born from a star. Kansas City, MI (PRWEB) March 06, 2013 For much of this century and the previous one, scientists have proposed and theorized about the origins of planets and moons and how they formed; most of the scientific community have settled on the “Accretion” hypothesis for planet formation; which states that...

NASA [ Watch The Video ] In the evening of Feb. 5, 2013, the sun erupted with two coronal mass ejections or CMEs that may glance near-Earth space. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and ESA/NASA’s Solar and Heliospheric Observatory, show that the first CME began at 7 p.m. EST and left the sun at speeds of around 750 miles per second. The second CME began at 10:36 p.m. EST and left the sun at speeds of...

NASA [ Watch The Video ] On Jan. 31, 2013 at 2:09am EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and ESA/NASA’s Solar and Heliospheric Observatory, show that the CME left the sun at speeds of around 575 miles per second, which is a fairly typical speed for CMEs. Historically, CMEs at this speed are mild. Not to be confused with a solar...

[ Watch the Video: SOHO Captures CME On January 23, 2013 ] Lee Rannals for redOrbit.com - Your Universe Online The sun showed off its strength on Wednesday with two coronal mass ejections (CME), observed by both NASA and the European Space Agency instruments. NASA's Solar Terrestrial Relations Observatory (STEREO) and both of the space agencies' Solar and Heliospheric Observatory (SOHO) helped to unveil the activity during the solar maximum cycle. The CME seen at 9:55 a.m. EST on...

redOrbit Staff & Wire Reports - Your Universe Online On Thursday, October 25, NASA's twin Solar Terrestrial Relations Observatory (STEREO) program celebrated its sixth anniversary orbiting the sun, the US space agency announced on Friday. The twin orbiting probes were launched on that date in 2006, and ultimately entered into similar but separate orbits around the sun. STEREO-A's orbit is slightly smaller and faster, while STEREO-B's is larger and slower, they said, and those subtle...

[Watch The Video] [Listen to EarthSong] Lawrence LeBlond for redOrbit.com - Your Universe Online Earth is filled with many sounds and no matter where you go it is inescapable. From the roar of the city streets, to the ever-pleasing sounds of nature, and the endless commotion of human chatter. But there is one sound that most of us have never heard: the sound of the Earth itself. The sound (or song) is called “chorus,” explains Craig Kletzing of the University of Iowa. This...

Lee Rannals for redOrbit.com - Your Universe Online Scientists are using data from NASA's Lunar Reconnaissance Orbiter (LRO) to develop a way to explore the Moon in three dimensions. The team used images taken from different angles and were able to generate rich 3D maps of the surface of the Moon. The way a human brain deciphers three dimensions is that our eyes are slightly apart, and are able to see the world at separate angles at the same time. The human brain is able to interpret...
