#Four #X-class #Flares
Image Credit: #NASA, #Solar Dynamics Observatory, #GSFC
Explanation: Swinging around the Sun’s eastern limb on Monday, a group of sunspots labeled active region AR1748 has produced the first four X-class solar flares of 2013 in less than 48 hours. In time sequence clockwise from the top left, flashes from the four were captured in extreme ultraviolet images from the Solar Dynamics Observatory. Ranked according to their peak brightness in #X-rays, #X-class flares are the most powerful class and are frequently accompanied by coronal mass ejections (CMEs), massive #clouds of high energy plasma launched into #space. But CMEs from the first three flares were not #Earth-directed, while one associated with the fourth flare may deliver a glancing blow to the Earth’s magnetic field on May 18. Also causing temporary radio blackouts, AR1748 is likely not finished. Still forecast to have a significant chance of producing strong flares, the active region is rotating into more direct view across the Sun’s nearside. (presso Fonderia)

#Kepler’s #Supernova Remnant in #X-Rays
Image Credit: X-ray: #NASA/CXC/NCSU/M. Burkey et al. Optical: DSS
Explanation: What caused this mess? Some type of star exploded to create the unusually shaped #nebula known as Kepler’s supernova remnant, but which type? Light from the stellar explosion that created this energized cosmic cloud was first seen on #planet #Earth in October 1604, a mere four hundred years ago. The supernova produced a bright new star in early 17th century skies within the constellation #Ophiuchus. It was studied by astronomer Johannes Kepler and his contemporaries, without the benefit of a #telescope, as they searched for an explanation of the heavenly apparition. Armed with a modern understanding of stellar #evolution, early 21st century astronomers continue to explore the expanding debris cloud, but can now use orbiting space telescopes to survey Kepler’s supernova remnant (SNR) across the spectrum. Recent X-ray data and images of Kepler’s supernova remnant taken by the orbiting Chandra X-ray Observatory has shown relative elemental abundances typical of a Type Ia supernova, and further indicated that the progenitor was a white dwarf star that exploded when it accreted too much material from a companion Red Giant star and went over Chandrasekhar’s limit. About 13,000 light years away, Kepler’s supernova represents the most recent stellar explosion seen to occur within our #Milky #Way #galaxy. (presso Fonderia)

#Partial #Solar #Eclipse with #Airplane
Image Credit & Copyright: #Phillip #Calais
Explanation: It was just eight minutes after #sunrise, last week, and already there were four things in front of the #Sun. The largest and most notable was #Earth’s #Moon, obscuring a big chunk of the Sun’s lower limb as it moved across the solar disk, as viewed from #Fremantle, #Australia. This was expected as the image was taken during a partial solar eclipse — an eclipse that left sunlight streaming around all sides of the Moon from some locations. Next, a band of clouds divided the Sun horizontally while showing interesting internal structure vertically. The third intervening body might be considered to be the Earth’s atmosphere, as it dimmed the Sun from its higher altitude brightness while density fluctuations caused the Sun’s edges to appear to shimmer. Although closest to the photographer, the least expected solar occulter was an airplane. Quite possibly, passengers on both sides of that airplane were contemplating the unusual view only visible out the eastern-facing windows. (presso Fonderia)

#Cape #York #Annular #Eclipse

Explanation: This week the #shadow of the #New #Moon fell on planet #Earth, crossing #Queensland’s Cape York in northern #Australia … for the second time in six months. On the morning of #May 10, the Moon’s apparent size was too small to completely cover the #Sun though, revealing a “ring of fire” along the central path of the annular solar eclipse. Near mid-eclipse from #Coen, Australia, a webcast team captured this telescopic snapshot of the annular phase. Taken with a hydrogen-alpha filter, the dramatic image finds the Moon’s silhouette just within the solar disk, and the limb of the active Sun spiked with solar prominences. Still, after hosting back-to-back solar eclipses, northern Australia will miss the next and final solar eclipse of 2013. This November, a rare hybrid eclipse will track across the North Atlantic and equatorial Africa. (presso Fonderia)
