Artist impression of the debris disk around HD 107146. This adolescent star system shows signs that in its outer reaches, swarms of Pluto-size objects are jostling nearby smaller objects, causing them to collide and “kick up” considerable dust.

Il Sole raggiunge il suo massimo fulgore ed inizia lentamente il suo declino, mentre la Luna sua compagna lo sostiene nell'ombra, entrambi celebrati da millenni sulla Terra, che ospita i frutti del loro Amore così grande e duraturo. Così anche il maschile ed il femminile si uniscono per rendere fecondo e portare alla Luce ogni Disegno Divino, nel ciclo continuo ed eterno della Vita. #solstizio #estate #maschile #femminile #coaching www.valeriapisano.com

Video: Space Slinky 5,000 Light-Years Long Discovered By Astronomers  Astronomers have assembled, from more than 13 years of observations from NASA’s Hubble Space Telescope, a series of time-lapse movies showing a jet of superheated gas — 5,000 light-years long — as it is ejected from a supermassive black hole.

PS1-12sk, the yellow dot at image center (circled), is classified as a very rare Type Ibn supernova - only the sixth such example found out of thousands of supernovae. It was discovered on the outskirts of a bright elliptical galaxy (the yellow blob to the upper left of the supernova) located about 780 million light-years from Earth. A Type Ibn supernova is thought to come from the explosion of a young, massive star.

ALMA image of the dust surrounding the star HD 107146. Dust in the outer reaches of the disk is thicker than in the inner regions, suggesting that a swarm of Pluto-size planetesimals is causing smaller objects to smash together. The dark ring-like structure in the middle portion of the disk may be evidence of a gap where a planet is sweeping its orbit clear of dust
