A look beyond stars in our Milky Way to galaxies beyond

A look beyond stars in our Milky Way to galaxies beyond

[CLICK ON IMAGE FOR HIGH RESOLUTION, Dietmar Hager, Eric Benson] This sharp telescopic field of view holds two bright galaxies. Barred spiral NGC 5101 (top right) and nearly edge-on system NGC 5078 are separated on the sky by about 0.5 degrees or about the apparent width of a full moon. Found within the boundaries of […]

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 […]

Guess which 2 celestial objects are within our Milky Way galaxy

[CLICK ON IMAGE FOR HIGH RESOLUTION, Bob Franke] Comet C/2014 S2 (PanSTARRS) poses for a Messier moment in this telescopic snapshot from April 18. In fact it shares the 1.5 degree wide field-of-view with two well-known entries in the 18th century comet-hunting astronomer’s famous catalog. Outward bound and sweeping through northern skies just below the […]

Why many galaxies, seen edge on, are extremely thin

Why many galaxies, seen edge on, are extremely thin

[CLICK ON IMAGE FOR HIGH RESOLUTION, NASA, ESA, Hubble Legacy Archive; Processed & Copyright: Hunter Wilson] Why is this galaxy so thin? Many disk galaxies are actually just as thin as NGC 5866, pictured above, but are not seen edge-on from our vantage point. One galaxy that is situated edge-on is our own Milky Way […]

Nearby spiral galaxy captured in all its glory by Hubble telescope

[CLICK ON IMAGE FOR HIGH RESOLUTION, ESA/Hubble & NASA and S. Smartt (Queen’s University Belfast), Robert Gendler] This huge swirling mass of stars, gas, and dust occurs near the center of a nearby spiral galaxy. Gorgeous spiral NGC 3521 is a mere 35 million light-years distant, toward the constellation Leo. Spanning some 50,000 light-years, its […]

Planetary dawn spectacular

Planetary dawn spectacular

[CLICK ON IMAGE FOR HIGH RESOLUTION, Yuri Beletsky (Carnegie Las Campanas Observatory, TWAN)] Planet Earth’s horizon stretches across this recent Solar System group portrait, seen from the southern hemisphere’s Las Campanas Observatory. Taken before dawn it traces the ecliptic with a line-up familiar to November’s early morning risers. Toward the east are bright planets Venus, […]

Fireball over the Swiss Alps

Fireball over the Swiss Alps

[CLICK ON IMAGE FOR HIGH RESOLUTION, Ivo Scheggia] A few days ago, a bright fireball was photographed from the Alps mountain range in Switzerland as it blazed across the sky. The fireball, likely from the Taurids meteor shower, was notable not only for how bright it was, but for the rare orange light it created […]

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 […]
