The outstanding Omega Centauri, largest and brightest star cluster in our Milky Way
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 […]
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 […]
The magnificent Orion nebula, powered by Trapezium, and observable by small telescopes
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 […]
Mars poses with the stars, Antares and M4
[CLICK ON IMAGE FOR HIGH RESOLUTION, Sebastian Voltmer] Wandering through this stunning field of view, Mars really is in front of these colorful cosmic clouds. The mosaic contructed from telescopic images is about 5 degrees (10 full moons) across. It captures the planet’s position on Aug. 26, over 7 light-minutes from Earth and very near […]
Check out the magnificent M13 globular star cluster with your binoculars
[CLICK ON IMAGE FOR HIGH RESOLUTION, Dean Fournier; Inset: ESA/Hubble & NASA] M13 is one of the most prominent and best known globular clusters. Visible with binoculars in the constellation of Hercules, M13 is frequently one of the first objects found by curious sky gazers seeking celestials wonders beyond normal human vision. M13 is a […]
The relatively nearby Formax Galaxy Cluster is only 62 million light years away
June 16, 2016 CLICK ON IMAGE FOR HIGH RESOLUTION, European Southern Observatory, Aniello Grado and Luca Limatola Named for the southern constellation toward which most of its galaxies can be found, the Fornax Cluster is one of the closest clusters of galaxies. About 62 million light-years away, it is almost 20 times more distant than […]
View from and of a robotic observatory in the Canary Islands
[CLICK ON IMAGE FOR HIGH RESOLUTION, Mads Fredslund Andersen, Stellar Astrophysics Centre, Aarhus Univ., Denmark] Near first quarter, the Moon in March lights this snowy, rugged landscape, a view across the top of Tenerife toward La Palma in the Canary Islands Spanish archipelago. The large Teide volcano, the highest point in Spain, looms over the […]
Omega Centauri is the largest globular star cluster and also nearby … and ancient
[CLICK ON IMAGE FOR HIGH RESOLUTION, Roberto Colombari] This huge ball of stars predates our Sun. Long before humankind evolved, before dinosaurs roamed, and even before our Earth existed, ancient globs of stars condensed and orbited a young Milky Way Galaxy. Of the 200 or so globular clusters that survive today, Omega Centauri is the […]
Lots of energy in that big, black sky: M31, Mirach and M33
[CLICK ON IMAGE FOR HIGH RESOLUTION, Malcolm Park (North York Astronomical Association)] Separated by about 14 degrees (28 Full Moons) in planet Earth’s sky, spiral galaxies M31 at left, and M33 are both large members of the Local Group, along with our own Milky Way galaxy. This narrow- and wide-angle, multi-camera composite finds details of […]
The amazing Sombrero Galaxy’s glowing central core
[CLICK ON IMAGE FOR HIS RESOLUTION, Hubble Heritage Team (AURA/STScI /NASA)] Why does the Sombrero Galaxy look like a hat? Reasons include the Sombrero’s unusually large and extended central bulge of stars, and dark prominent dust lanes that appear in a disk that we see nearly edge-on. Billions of old stars cause the diffuse glow […]
