Magnificent CME Erupts on the Sun with Earth to Scale (por NASA Goddard Photo and Video) On August 31, 2012 a long filament of solar material that had been hovering in the sun’s atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled at over 900 miles per second. The CME did not travel directly toward Earth, but did connect with Earth’s magnetic environment, or magnetosphere, causing aurora to appear on the night of Monday, September 3.

NOAA Satellite Captures Venus Transit (by NOAAVisualizations)

The NOAA GOES satellites are most commonly associated with the non-stop coverage of severe weather over the western hemisphere. However, one of the sensors on-board the GOES spacecraft, the Solar X-Ray Imager (SXI), points towards the Sun, providing constant monitoring of space weather, especially solar flares. On June 5th, the GOES-15 SXI captured the transit of Venus across the Sun. It can be seen in this animation as a small dark spot that crosses from left to right. The next transit of Venus visible by Earth will occur in 2117.

In 1859, Richard Carrington observed a large group of sunspots, and two solar flares. The flares’ path is marked A-C and B-D. This was one of the first observations of solar flares, which Carrington suspected were the cause of the disruption on Earth. Credit: Science Museum. (via Stories from the stores)

Lunar Eclipse As Seen From The Moon (2011.06.15) [720p] (by djxatlanta)

During the June 15, 2011 lunar eclipse, scientists will be able to get a unique view of the moon. While the sun is blocked by the Earth, LRO’s Diviner instrument will take the temperature on the lunar surface. Since different rock sizes cool at different rates, scientists will be able to infer the size and density of rocks on the moon. This animation shows the June 15 lunar eclipse as viewed from the Moon.

The sequence above shows the setting Sun dipping toward the western horizon as observed from Veszprem, Hungary. As the Sun sinks lower, its color becomes more reddened because the path length of sunlight is increasing, resulting in the shorter wavelength colors of light (blues and greens) being preferentially scattered from our view. The longer wavelengths (reds, oranges, yellows) remain to color the Sun. Only if clouds or sufficient aerosols are present will the sky take on shades of red. In this case, exposures were selected to enhance the Sun, not the sky. Note that the striped Sun in frame five is due to thin clouds near the horizon. Sunspots may be discerned in frames two and four (upper right quadrant). Photos taken on April 18, 2011. Credit: Monika Landy-Gyebnar (via EPOD)
