Too Close to a Black Hole

Explanation: What would you see if you went right up to a black hole?Featured is acomputer generated image highlighting how strange things would look. The black holehas such strong gravity that light is noticeably bent towards it - causing some very unusualvisual distortions. Every star in the normal frame has at least two bright images - one on each side of theblack hole. Near theblack hole, you can see the whole sky - light fromevery direction is bentaroundand comes back to you. The original background map was taken from the2MASS infrared sky survey, with stars from theHenry Draper catalog superposed. Black holesare thought to be the densest state of matter, and there isindirect evidencefor their presence instellar binary systems and the centers ofglobular clusters,galaxies, andquasars.

Explanation: A New Moonjoined giant sunspot group AR 2192 to dim the bright solar disk during Thursday'smuch anticipated partial solar eclipse.Visible from much of North America, the Moon's broad silhouette is captured in this extreme telephoto snapshot near eclipse maximum from Santa Cruz, California. About the size of Jupiter, theremarkable AR 2192 itself darkens a noticeable fraction of the Sun, near center and below the curved lunar limb. As the sunspot group slowly rotatesacross the Sun and out of view in the coming days its activity is difficultto forecast. But the timing ofsolar eclipses is easier to predict. The next will be a total solar eclipse onMarch 20, 2015.
