The North America Nebula (NGC7000) is part of the same H II region as its smaller neighbour, the Pelican Nebula (IC 5070). The two nebulae are separated by a molecular cloud of dark obscuring dust. They are both located in the Orion Arm of the Milky Way.
Galactic Cirrus aka Integrated Flux Nebulae
David Elmore
This week I got in some observing of very faint whips in the galaxy. Here is a region containing two galaxies, M81 and M82, often imaged close up against a black background. The background (actually foreground) is anything but black but is in fact full of dust that is illuminated by light from all the stars in the galaxy itself.

Comet T2 passing Coddington’s Nebula
Dr. Brian Ottum
Coddington’s Nebula is a rather close “dwarf” galaxy. Astronomers have determined that 90% of its mass is INVISIBLE to us – it is dark matter. Yet we know little about dark matter.

M51 Whirlpool Galaxy lies 23 million light years from Earth and has an estimated diameter 0f 76,000 light years. Overall the galaxy is about 76% of the Milky Way.
First Light: M51
Mark Striebeck
M51 is a spiral galaxy in a distance of 23 million light years and has a diameter of 76,000 light years – which means it’s slightly smaller than our own galaxy (105,700 light years). It was discovered by Charless Messier on October 13, 1775 – though he only discovered the main galaxy. The smaller galaxy (NGC 5159) was discovered 6 years later by Pierre Méchain. The most prominent feature of this galaxy is the encounter with the smaller galaxy (at the bottom in the image). Although it looks like a frontal encounter, the smaller galaxy (NGC 5159) is actually passing behind the larger galaxy. This process has been going on for hundreds of millions of years.

The Pleiades, also known as the Seven Sisters and Messier 45, is an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. It is among the star clusters nearest to Earth, it is the nearest Messier object to Earth, and is the cluster most obvious to the naked eye in the night sky.
Exploring the Antennae
Bernard Miller
Some 60 million light-years away in the southerly constellation Corvus, two large galaxies are colliding. Stars in the two galaxies, cataloged as NGC 4038 and NGC 4039, very rarely collide in the course of the ponderous cataclysm that lasts for hundreds of millions of years. But the galaxies’ large clouds of molecular gas and dust often do, triggering furious episodes of star formationi near the center of the cosmic wreckage. Spanning over 500 thousand light-years, this stunning view also reveals new star clusters and matter flung far from the scene of the accident by gravitational tidal forces. The remarkably sharp ground-based image includes narrowband data that highlights the characteristic red glow of atomic hydrogen gas in star-forming regions. The suggestive overall visual appearance of the extended arcing structures gives the galaxy pair its popular name – The Antennae.
