NGC 7024: Туманность Ирис NGC 7023: The Iris Nebula
4.11.2004

Like delicate cosmic petals, these clouds of interstellar dust and gas have blossomed 1,300 light-years away in the fertile star fields of the constellation Cepheus. Sometimes called the Iris Nebula and dutifully cataloged as NGC 7023, this is not the only nebula in the sky to evoke the imagery of flowers.

Туманности в Орионе Orion Nebulosities
30.05.2002

Adrift 1,500 light-years away in one of the night sky's most recognizable constellations, the glowing Orion Nebula and the dark Horsehead Nebula are contrasting cosmic vistas. They both appear in this stunning composite color photograph along with other nebulosities as part of the giant Orion Molecular Cloud complex, itself hundreds of light-years across.



Петля Барнарда вокруг туманности Конская Голова Barnards Loop around the Horsehead Nebula
24.02.2009

Why is the Horsehead Nebula surrounded by a bubble? Although hard to make out above, the famous Horsehead Nebula is the slight dark indentation in the bright streak just to the left of the image center. Glowing like an emission nebula, the origin of the bubble, known as Barnard's Loop, is currently unknown.

Why is the Horsehead Nebula surrounded by a bubble? Although glowing like an emission nebula, the origin of the bubble, known as Barnard's Loop, is currently unknown. Progenitor hypotheses include the winds from bright Orion stars and the supernovas of stars long gone.



IC 2948: туманность Бегущий Цыпленок IC 2948: The Running Chicken Nebula
18.04.2008

Bright nebulae abound in and around the expansive southern constellation of Centaurus. This one, cataloged as IC 2948 is near the star Lambda Centauri and not far on the sky from the better known Eta Carinae Nebula.



Туманность и нейтронная звезда The Nebula And The Neutron Star
1.02.2003

The lonely RX J1856.5-3754 was formed from the collapsed core of an exploding star. At a distance of 180 light-years it is the closest known neutron star. More massive than...



Петля Барнарда вокруг Ориона Barnards Loop Around Orion
20.04.2005

Why is the belt of Orion surrounded by a bubble? Although glowing like an emission nebula, the origin of the bubble, known as Barnard's Loop, is currently unknown. Progenitor hypotheses include the winds from bright Orion stars and the supernovas of stars long gone.



NGC 7822 в Цефее NGC 7822 in Cepheus
28.08.2009

Pillars of gas, dust, and young, hot stars fill the center of NGC 7822. At the edge of a giant molecular cloud toward the northern constellation Cepheus, the glowing star forming region lies about 3,000 light-years away. Within the nebula, bright edges and tantalizing shapes are highlighted in this colorful skyscape.



Головастики в IC 410 The Tadpoles of IC 410
11.01.2006

This close-up view shows a portion of otherwise faint emission nebula IC 410 in striking false-colors. It also shows two remarkable denizens of the glowing gas cloud at the right - the "tadpoles" of IC 410. The picture is a composite of images taken through narrow band filters intended to trace atoms in the nebula.
