Central disk of our spiral galaxy from Monument Valley

Central disk of our spiral galaxy from Monument Valley

[CLICK ON IMAGE FOR HIGH RESOLUTION, Wally Pacholka (AstroPics.com, TWAN)] You don’t have to be at Monument Valley to see the Milky Way arch across the sky but it helps. Only at Monument Valley USA would you see a picturesque foreground that includes these iconic rock peaks called buttes. Buttes are composed of hard rock […]

Cluster of 10 million stars: Part of Milky Way or its own galaxy?

Cluster of 10 million stars: Part of Milky Way or its own galaxy?

[FOR HIGH RESOLUTION CLICK ON IMAGE,CEDIC Team, Processing – Christoph Kaltseis] Globular star cluster Omega Centauri, also known as NGC 5139, is some 15,000 light-years away. The cluster is packed with about 10 million stars much older than the Sun within a volume about 150 light-years in diameter, the largest and brightest of 200 or […]

The center of our galaxy as viewed from Chile at dawn

[CLICK ON IMAGE FOR HIGH RESOLUTION, Babak Tafreshi (TWAN), ESO Ultra HD Expedition As dawn broke on March 27, the center of the Milky Way Galaxy stood almost directly above the European Southern Observatory’s Paranal Observatory. In the dry, clear sky of Chile’s Atacama desert, our galaxy’s dusty central bulge is flanked by Paranal’s four […]

Hubble provides closeup of 100,000 stars in M15 near our galaxy’s center

[CLICK ON IMAGE FOR HIGH RESOLUTION, Hubble, NASA] Stars, like bees, swarm around the center of bright globular cluster M15. This ball of over 100,000 stars is a relic from the early years of our Galaxy, and continues to orbit the Milky Way’s center. M15, one of about 170 globular clusters remaining, is noted for […]

Radio image of large galaxy reveals huge plasma jets

Radio image of large galaxy reveals huge plasma jets

[FOR HIGH RESOLUTION, CLICK ON IMAGE] The galaxy at the image center, Hercules A, appears to be a relatively normal elliptical galaxy in visible light. When imaged in radio waves, however, tremendous plasma jets over one million light years long appear. Detailed analyses indicate that the central galaxy, also known as 3C 348, is actually […]

Stardust memories

Stardust memories

[CLICK ON IMAGE FOR HIGH RESOLUTION] Cosmic dust clouds sprawl across a rich field of stars in this sweeping telescopic vista near the northern boundary of Corona Australis, the Southern Crown. Probably less than 500 light-years away and effectively blocking light from more distant, background stars in the Milky Way, the densest part of the […]

The nearest star in our galaxy is actually three

The nearest star in our galaxy is actually three

The glare of Alpha Centauri, one of the brightest stars in planet Earth’s night sky, floods the left side of this southern skyscape. A mere 4.3 light-years distant, Alpha Centauri actually  consists of two component stars similar in size to the Sun, locked in a mutual orbit. Much smaller and cooler, a third member of […]

Head on collision: Milky Way and Andromeda to merge … in a few billion years

Head on collision: Milky Way and Andromeda to merge … in a few billion years

Will our Milky Way Galaxy collide one day with its larger neighbor, the Andromeda Galaxy? Most likely, yes. Careful plotting of slight displacements of M31’s stars relative to background galaxies on recent Hubble Space Telescope  images indicate that the center of M31  could be  on a direct collision course with the center of our home […]
