CONTENTS
- Photo taken by the Hubble Space Telescope
This image from the Hubble Space Telescope shows a planetary nebula, the glowing remains of a dying star that was about five times the mass of the Sun. The glowing gas is the star’s outer layers, expelled about 2,200 years ago. - Facts of interest about the image
The “butterfly” stretches for more than two light-years, which is about half the distance from the Sun to the nearest star, Alpha Centauri. - Classroom activity
Included is an inquiry-based classroom activity that focuses on the image and text.
CONTENTS
- Photo taken by the Hubble Space Telescope
This image from the Hubble Space Telescope shows the tip of a huge pillar of star birth in a turbulent stellar nursery called the Carina Nebula. Nestled inside this dense structure are fledgling stars. The stars cannot be seen in this image because they are hidden by a wall of gas and dust. - Facts of interest about the image
Although the infant stars are invisible, one of them is providing evidence for its existence. Thin puffs of material can be seen traveling to the left and to the right of a dark notch in the center of the pillar. The matter is part of a jet produced by a young star. - Classroom activity
Included is an inquiry-based classroom activity that focuses on the image and text.
CONTENTS
- Photo taken by the Hubble Space Telescope
The image shows a thin ribbon seemingly draped across this portion of the sky. In reality, this ribbon marks the expanding blast wave from a supernova explosion that occurred more than 1,000 years ago. - Facts of interest about the image
The transparent nature of the ribbon of glowing gas is apparent from the background objects visible through the material. - Classroom activity
Included is an inquiry-based classroom activity that focuses on the image and text.
CONTENTS
- Photo taken by the Hubble Space Telescope
This image shows the colorful "last hurrah" of a star like our Sun. The star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star's remaining core. - Facts of interest about the image
The burned-out star, one of the hottest known white dwarfs, is the white dot in the center of the image. Our Sun will eventually burn out and shroud itself with stellar debris, but not for another 5 billion years. - Classroom activity
Included is an inquiry-based classroom activity that focuses on the image and text.
Crab Nebula (M1) lithograph
CONTENTS
- Photo taken by the Hubble Space Telescope
This image from the Hubble Space Telescope is a mosaic assembled from 24 individual exposures. The text explains the history of observation of the Crab Nebula from its formation as a spectacular supernova in 1054 to the discovery of the first pulsar at its center. - Facts of interest about the image
The lithograph includes an X-ray image of the nebula, which shows the pulsar. - Classroom activity
Included is an inquiry-based classroom activity that focuses on the image and text.
Cat's Eye Nebula (NGC 6543) lithograph
CONTENTS
- Photo taken by the Hubble Space Telescope
This image from the Hubble Space Telescope reveals new details of the Cat’s Eye Nebula, one of the most complex planetary nebulae ever seen. Understanding how and why planetary nebulae form is made complicated by vast distances and the fixed orientations of these Sun-like stars undergoing their last gasps. - Facts of interest about the image
The lithograph includes text and images of other nebulae, emphasizing that no two are alike. - Classroom activity
Included is an inquiry-based classroom activity that focuses on the image and text.
Globular Cluster M80 lithograph
CONTENTS
- Photo taken by the Hubble Space Telescope
This image from the Hubble Space Telescope shows a tightly packed crowd of stars resembling a swarm of bees. Called M80 (NGC 6093), the stellar swarm is one of the densest globular clusters in our Milky Way galaxy. - Facts of interest about the image
The text contains information about the characteristics of globular clusters and contrasts them with open clusters. - Classroom activity
Included is an inquiry-based classroom activity that focuses on the image and text.
NGC 346 in the Small Magellanic Cloud lithograph
CONTENTS
- Photo taken by the Hubble Space Telescope
This image from the Hubble Space Telescope illustrates the rite of passage for clusters of developing stars: from their sheltered growth in a dark cloud of dust and gas, to their powerful debut as a grouping of young stars, to their settlement into adulthood. - Facts of interest about the image
The text includes information about the process of star formation illustrated in the image. - Classroom activity
Included is an inquiry-based classroom activity that focuses on the image and text.
Stellar Spire in the Eagle Nebula lithograph
CONTENTS
- Photo taken by the Hubble Space Telescope
This image from the Hubble Space Telescope shows light from hot stars eating away the surface of the dust and gas cloud in this region to reveal a pillar composed of denser material. - Facts of interest about the image
The text includes information about the process of star formation taking place in the nebula. - Classroom activity
Included is an inquiry-based classroom activity that focuses on the image and text.
Helix Nebula lithograph
CONTENTS
- Photo taken by the Hubble Space Telescope
The Helix is a tube-shaped planetary nebula, an expanding shell of gas around a dying star. This Hubble image stares straight into the barrel of the tube. - Facts of interest about the image
Text explains the Helix Nebula's appearance and gives general information on planetary nebula formation. - Classroom activity
Included is an inquiry-based classroom activity that focuses on the image and text.
Orion Nebula lithograph
CONTENTS
- Photo taken by the Hubble Space Telescope
This Hubble Space Telescope image shows the Orion Nebula, featuring a "cavern" containing four of the nebula's hottest and most massive stars. - Facts of interest about the image
Background text describes why the Orion Nebula is considered a "crucible of creation" and provides definitions as well as fast facts.
Helix Nebula "Knots" lithograph
CONTENTS
- Photo taken by the Hubble Space Telescope
This Hubble Space Telescope image shows thousands of gigantic tadpole-shaped objects surrounding a dying star in the Helix Nebula. - Facts of interest about the image
Background text describes these objects and how they may have formed and provides definitions as well as fast facts.
Eagle Nebula lithograph
CONTENTS
- Photo taken by the Hubble Space Telescope
