APOD: 2021 August 23 - Abell 3827: Cannibal Cluster Gravitational Lens Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2021 August 23 Abell 3827: Cannibal Cluster Gravitational Lens Image Credit: ESA/Hubble & NASA, R. Massey Explanation: Is that one galaxy or three?Toward the right of the featured Hubble image of the massive galaxy cluster Abell 3827 is what appears to be a most unusual galaxy -- curved and with three centers. A detailed analysis, however, finds that these are three images of the same background galaxy -- and that there are at least four more images. Light we see from the single background blue galaxy takes multiple paths through the complex gravity of the cluster, just like a single distant light can take multiple paths through the stem of a wine glass.Studying how clusters like Abell 3827 and their component galaxies deflect distant light gives information about how mass and dark matter are distributed.Abell 3827 is so distant, having a redshift of 0.1, that the light we see from it left about 1.3 billion years ago -- before dinosaurs roamed the Earth.Therefore, the cluster's central...

APOD: 2021 August 22 - Explosions from White Dwarf Star RS Oph Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2021 August 22 Explosions from White Dwarf Star RS Oph Illustration Credit & Copyright: David A. Hardy & PPARC Explanation: Spectacular explosions keep occurring in the binary star system named RS Ophiuchi. Every 20 years or so, the red giant star dumps enough hydrogen gas onto its companion white dwarf star to set off a brilliant thermonuclear explosion on the white dwarf's surface. At about 5,000 light years distant, the resulting nova explosions cause the RS Oph system to brighten up by a huge factor and become visible to the unaided eye. The red giant star is depicted on the right of the above drawing, while the white dwarf is at the center of the bright accretion disk on the left. As the stars orbit each other, a stream of gas moves from the giant star to the white dwarf. Astronomers speculate that at some time in the next 100,000 years, enough matter will have accumulated on the white dwarf to push it over the...

APOD: 2021 August 18 - Rings Around the Ring Nebula Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2021 August 18 Rings Around the Ring Nebula Image Credit: Hubble, Large Binocular Telescope,Subaru Telescope; Composition & Copyright: Robert Gendler Explanation: The Ring Nebula (M57), is more complicated than it appears through a small telescope. The easily visible central ring is about one light-year across,but this remarkably deep exposure -a collaborative effort combining data from three different large telescopes -exploresthe looping filaments of glowing gas extending much farther from the nebula's central star.This composite image includes red light emitted by hydrogen as well asvisible and infrared light.The Ring Nebula is an elongated planetary nebula, a type of nebula created when a Sun-like star evolves to throw off its outer atmosphere to become a white dwarf star. The Ring Nebula is about 2,500 light-years away toward the musicalconstellationLyra.

APOD: 2021 August 16 - Perseid Meteor, Red Sprites, and Nova RS Oph Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2021 August 16 Perseid Meteor, Red Sprites, and Nova RS Ophiuchus Image Credit & Copyright: Daniel Korona Explanation: This was an unusual sky.It wasn't unusual because of the central band the Milky Way Galaxy, visible along the image left. Most dark skies show part of the Milky Way.It wasn't unusual because of the bright meteor visible on the upper right.Many images taken during last week's Perseid Meteor Shower show meteors, although this Perseid was particularly bright.This sky wasn't unusual because of the red sprites, visible on the lower right.Although this type of lightning has only been noted in the past few decades, images of sprites are becoming more common.This sky wasn't unusual because of the nova, visible just above the image center.Novas bright enough to be seen with the unaided eye occur every few years, with pictured Nova RS Ophiuchus discovered about a week ago. What was most unusual, though, was to capture all these things together, in a single night, on a single...

APOD: 2021 August 11 - Mammatus Clouds over Saskatchewan Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2021 August 11 Mammatus Clouds over Saskatchewan Image Credit & Copyright: Michael F Johnston Explanation: When do cloud bottoms appear like bubbles?Normally, cloud bottoms are flat.This is because moist warm airthat rises and cools will condense into water droplets at a specific temperature, which usually corresponds to a very specific height. As waterdroplets grow, an opaque cloud forms. Under some conditions, however, cloud pockets can develop that contain large droplets of water or ice that fall into clear air as they evaporate. Such pockets may occur in turbulent air near a thunderstorm. Resulting mammatus clouds can appear especially dramatic if sunlit from the side. The mammatus clouds pictured here, lasting only a few minutes, were photographed over Regina,Saskatchewan, Canada,just after a storm in 2012.
