NASA Warns ‘Something Unexpected Is Happening To The Sun’
” ‘Sunspot numbers are well below their values from 2011, and strong solar flares have been infrequent,’ the space agency says.
The image above shows the Earth-facing surface of the Sun on February 28, 2013, as observed by the Helioseismic and Magnetic Imager (HMI) on NASA’s Solar Dynamics Observatory.
It observed just a few small sunspots on an otherwise clean face, which is usually riddled with many spots during peak solar activity.
Experts have been baffled by the apparent lack of activity – with many wondering if NASA simply got it wrong.
However, Solar physicist Dean Pesnell of NASA’s Goddard Space Flight Center believes he has a different explanation.”
” NASA has released some stunning images this month, and here are the top 10 most incredible visuals published online in January, ranging from pics of snow-covered deserts to a galaxy found in the Milky way.
has long been known for being a digital pioneer, often making photos and videos available as soon as possible. Online, their pics are readily available with complete descriptions and fall under the public domain copyright (NASA is a government agency).”
“This new view of the historical supernova remnant Cassiopeia A, located 11,000 light-years away, was taken by NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR. Blue indicates the highest energy X-ray light, where NuSTAR has made the first resolved image ever of this source”

” SPECTACULAR JETS powered by the gravitational energy of a supermassive black hole in the core of the elliptical galaxy Hercules A illustrate the combined imaging power of two of astronomy’s cutting-edge tools, the Hubble Space Telescope’s Wide Field Camera 3, and the recently upgraded Karl G. Jansky Very Large Array (VLA) radio telescope in west-central New Mexico.
Some two billion light-years away, the yellowish elliptical galaxy in the center of the image appears quite ordinary as seen by Hubble in visible wavelengths of light. The galaxy harbors a 2.5-billion-solar-mass central black hole that is 1,000 times more massive than the black hole in our Milky Way. But the innocuous-looking galaxy, also known as 3C 348, has long been known as the brightest radio-emitting object in the constellation Hercules. Emitting nearly a billion times more power in radio wavelengths than our Sun, the galaxy is one of the brightest extragalactic radio sources in the entire sky. “
