How our galaxy would look from the side

How our galaxy would look from the side

[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 […]

Another supernova explodes in a galaxy know for them

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, […]

NGC 3628: The Hamburger Galaxy

NGC 3628: The Hamburger Galaxy

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 […]

Disturbance in the ‘force’: Did passing galaxy cause ‘Polar Ring’ NGC 660’s shape?

Disturbance in the ‘force’: Did passing galaxy cause ‘Polar Ring’ NGC 660’s shape?

[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 […]

A galaxy couple 300 million light years away

[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 […]
