Similar in size to the Milky Way, elliptical galaxy NGC 7600 is about 160 million light-years distant. In this deep image, spanning about 1/2 degree on the sky toward the constellation Aquarius, NGC 7600 sports a remarkable outer halo of nested shells and broad circumgalactic structures. The tantalizing features can be explained by the accretion of dark matter and stars on a cosmic timescale.     Shell Galaxy NGC 7600  Image Credit & Copyright: Ken Crawford ... Full Story

In 185 AD, Chinese astronomers recorded the appearance of a new star in the Nanmen asterism - a part of the sky identified with Alpha and Beta Centauri on modern star charts. The new star was visible for months and is thought to be the earliestrecorded supernova. This multiwavelength composite image from orbiting telescopes of the 21st century, XMM-Newton and Chandra in X-rays, and Spitzer and WISE in infrared, shows RCW 86, understood to be the remnant of that stellar explosion.RCW 86: ...

Sky Tonight—February 18, Moon rises with Leo the Lion, harbinger of spring

Courtesy of EarthSky A Clear Voice for Science Visit EarthSky at www.EarthSky.org About two hours after sunset on February 18, look for the waning gibbous moon and the constellation Leo the Lion shining side by side over the eastern horizon. The fainter stars of Leo might be hard to make out in the lunar glare tonight, but you should be able to spot Regulus, Leo’s brightest star, and one of the brightest stars in our night sky.

Later at night, you will find Orion in the southwest. Above Orion’s Belt, you will find one of the sky’s most famous stars, ruddy-hued Betelgeuse. Kids especially like Betelgeuse, because its name ... Full Story
