Galaxies on edge

Galaxies on edge

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 well-groomed constellation Coma Berenices. This sharp, colorful image reveals the galaxy’s bulging central core cut by […]

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 […]

Star factory: Coddington’s dwarf galaxy in the M81 groups

Star factory: Coddington’s dwarf galaxy in the M81 groups

Grand spiral galaxies often seem to get all the glory, flaunting their young, bright, blue star clusters in beautiful, symmetric spiral arms. But small, irregular galaxies form stars too. In fact dwarf galaxy IC 2574 shows clear evidence of intense star forming activity in its telltale pinkish regions of glowing hydrogen gas. Just as in […]

His shots of Wall Street Canyon at Bryce Canyon National Park with the stars of our own […]

Our Andromeda: Next door neighbor in local galaxy group

Our Andromeda: Next door neighbor in local galaxy group

A mere 2.5 million light-years away, the Andromeda Galaxy really is just next door as large galaxies go. So close, and spanning some 260,000 light-years, it took 11 different image fields from the Galaxy Evolution Explorer (GALEX) satellite’s telescope to produce this gorgeous portrait of the spiral galaxy in ultraviolet light. While its spiral arms […]

Hubble’s awesome look at a black dot of nothingness in the sky

Hubble’s awesome look at a black dot of nothingness in the sky

Here’s an excellent high definition video on the Hubble Ultra Deep Field images, with a 3D simulation that flies you through Hubble’s most awe-inspiring photographs. The Deep Field images were created by pointing the Hubble Space Telescope for several days at a tiny patch of apparently empty sky — “empty” sky that turned out to […]
