July 24, 2017 [CLICK HERE FOR HIGH RESOLUTION: Mike O’Day] Behold the largest ball of stars in our galaxy. Omega Centauri is packed with about 10 million stars, many older than our Sun and packed within a volume of only about 150 light-years in diameter. The star cluster is the largest and brightest of 200 […]
[Click Here for High Resolution, Lóránd Fényes] Is our Galaxy this thin? We believe so. The magnificent spiral galaxy NGC 4565 is viewed edge-on from planet Earth. Also known as the Needle Galaxy for its narrow profile, bright NGC 4565 is a stop on many telescopic tours of the northern sky, in the faint but […]
May 21, 2017 Utah amateur Patrick Wiggins discovered a possible bright supernova in the spiral galaxy NGC 6946 in Cygnus on May 13. If confirmed, 2017 eaw will become the 10th supernova found in this explosion-rich galaxy in the past century, reaffirming its reputation for fireworks of the grandest kind. It was Wiggins’s third supernova, […]
What is pictured is a sharp telescopic view of a magnificent edge-on spiral galaxy NGC 3628, a puffy galactic disk divided by dark dust lanes. Of course, this deep galactic portrait puts some astronomers in mind of its popular moniker, The Hamburger Galaxy. The tantalizing island universe is about 100,000 light-years across and 35 million […]
April 25, 2017 On April 12, as the Sun was blocked by the disk of Saturn the Cassini spacecraft camera looked toward the inner Solar System and the gas giant’s backlit rings. At the top of the mosaicked view is the A ring with its broader Encke and narrower Keeler gaps visible. At the bottom […]
March 12, 2017 [CLICK ON IMAGE FOR HIGH RESOLUTION, Christoph Kaltseis, CEDIC 2017] Near the center of this sharp cosmic portrait, at the heart of the Orion Nebula, are four hot, massive stars known as the Trapezium. Tightly gathered within a region about 1.5 light-years in radius, they dominate the core of the dense Orion […]
[CLICK ON IMAGE FOR HIGH RESOLUTION / CHART32 Team, Processing – Johannes Schedler] Over 40 million light-years away and swimming within the boundaries of the constellation Pisces, NGC 660’s peculiar appearance marks it as a polar ring galaxy. A rare galaxy type, polar ring galaxies have a substantial population of stars, gas, and dust orbiting […]
Jan. 31, 2017 [CLICK ON IMAGE FOR HIGH RESOLUTION, NASA, JSC, ESRS] Astronauts aboard the International Space Station see some amazing vistas, one of which was captured in this breathtaking picture in mid-2015. First, visible at the top, are parts of the space station itself including solar panels. Just below the station is the band […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Wolfgang Ries / Stefan Heutz (Astrokooperation)] The two eye-catching galaxies lie far beyond the Milky Way, at a distance of over 300 million light-years. Their distorted appearance is due to gravitational tides as the pair engage in close encounters. Cataloged as Arp 273 (also as UGC 1810), the galaxies […]
September 20, 2016 It’s hard to believe that more than 4 years have passed since the Curiosity rover (a.k.a. NASA’s Mars Science Laboratory) dropped onto the broad floor of Gale crater and began its marathon exploration of Mars. Although the craft’s “primary mission” spanned only 23 months, the hope has always been that this durable, […]
