Science Experiment Requires New Altitude For Space Station
2013-07-02 10:44:28

Lee Rannals for redOrbit.com - Your Universe Online Crew members aboard the International Space Station (ISS) had to add a little more distance between the orbiting laboratory and Earth on Sunday for a science experiment. NASA said astronauts raised the space station's altitude to accommodate a research project aimed at learning about Earth's atmosphere and climate change. "The European scientists requested that we reposition the station slightly because by having this period of time...

M5.9 Solar Flare Emitted By The Sun
2013-06-11 09:18:19

NASA The sun emitted a mid-level solar flare, peaking at 6:49 p.m. on June 7, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours. This flare is classified as an...

M-Class Solar Flare And Two Coronal Mass Ejections Detected Mid-Week
2013-05-23 07:00:42

Lawrence LeBlond for redOrbit.com - Your Universe Online As the peak year of the solar maximum picks up in intensity, NASA´s Solar Dynamics Observatory (SDO) observed yet another solar flare and two coronal mass ejections (CMEs) mid-week. On Wednesday May 22 the sun emitted an M7 solar flare, which peaked at about 9:38 a.m. EDT. While it was not immediately clear if the M-class flare also produced a CME, NASA confirmed later that the flare was associated with a CME. While this CME...

Coronal Mass Ejection Heads Toward Earth This Weekend
2013-05-19 07:37:21

[WATCH VIDEO: Coronal Mass Ejection On May 17, 2013] Lawrence LeBlond for redOrbit.com - Your Universe Online On May 17, the sun unleashed an Earth-directed coronal mass ejection (CME) at 5:24 a.m. EDT sending billions of tons of solar particles into space. The matter from this CME will likely reach Earth in one to three days and potentially affect electronic systems in satellites and possibly the International Space Station (ISS). NASA research models based on observations from...

Solar Activity Continues On The Sun
2013-05-15 11:28:59

NASA Solar activity continued on May 14, 2013, as the sun emitted a fourth X-class flare from its upper left limb, peaking at 9:48 p.m. EDT. This flare is classified as an X1.2 flare and it is the 18th X-class flare of the current solar cycle. The flare caused a radio blackout — categorized as an R3, or strong, on NOAA´s space weather scales from R1 to R5 -- which has since subsided. The flare was also associated with a non-Earth-directed CME. CMEs and flares are separate but...

The Impacts Of Strong Solar Flares
2013-05-14 07:53:54

NASA Given a legitimate need to protect Earth from the most intense forms of space weather -- great bursts of electromagnetic energy and particles that can sometimes stream from the sun -- some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth, but this is not actually possible. Solar activity is indeed currently ramping up toward what is known as solar maximum, something that occurs approximately every 11 years. However, this same solar cycle...

Sun Produces An X1.7 Solar Flare, Followed By An X2.8
2013-05-13 12:04:28

Lawrence LeBlond for redOrbit.com - Your Universe Online On Sunday (May 12) the Sun emitted a significant solar flare that is being classified as the first X-class event of 2013. The X1.7 flare, which peaked at about 10 p.m. EDT, was also associated with another solar event known as a coronal mass ejection (CME). While CMEs can release radiation and solar material in the direction they were produced, Sunday´s phenomenon was not directed at Earth. While solar flares also have the...

SDO Captures 3 Years Of Sun Activity In Spectacular Video
2013-04-22 19:09:25

Lee Rannals for redOrbit.com — Your Universe Online NASA has released a video of the unbroken coverage of the sun for the past three years, taken by its Solar Dynamics Observatory (SDO). The spacecraft's Atmospheric Imaging Assembly snaps a shot of the sun every twelve seconds in ten different wavelengths. The latest video shows the past three years of the sun at a pace of two images per day. [ Watch the Video: Three Years With Solar Dynamics Observatory ] The video,...

Astronomers Discover Solar Wind Energy Source
2013-03-08 12:36:32

NASA Science Using data from an aging NASA spacecraft, researchers have found signs of an energy source in the solar wind that has caught the attention of fusion researchers. NASA will be able to test the theory later this decade when it sends a new probe into the sun for a closer look. The discovery was made by a group of astronomers trying to solve a decades-old mystery: What heats and accelerates the solar wind? The solar wind is a hot and fast flow of magnetized gas that streams...

Twin Peaks For Solar Cycle?
2013-03-02 07:29:34

redOrbit Staff & Wire Reports - Your Universe Online While 2013 is supposed to be the year of Solar Max - the peak of the 11-year sunspot cycle - the relatively low solar activity recorded thus far has led experts to conclude that an unusual phenomenon has occurred. This most recent solar cycle has had not one but two peaks. According to NASA, sunspot numbers during the months of January and February 2013 were well below values recorded back in 2011. Furthermore, they report that...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...

Solar Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...
