A three tril­lion mile-long jet called HH-47 resem­bles a glow­ing worm in this NASA Hub­ble Space Tele­scope image. Jets are com­mon around newly formed stars. They are the exhaust prod­uct of the chaotic for­ma­tion of the star.

Chaos reigns in the cen­ter of this butterfly-shaped neb­ula in the con­stel­la­tion Pup­pis. NGC 2440 is a plan­e­tary neb­ula and is the remains of a star like our Sun. The com­plex struc­ture within the cen­ter of this neb­ula sug­gest to astronomers that the star has ejected mate­r­ial peri­od­i­cally in var­i­ous directions.

Starry Bug

Float­ing like a bug under a micro­scope, I Zwicky 18 is an odd-looking galaxy. Astronomers pre­vi­ously thought this pecu­liar galaxy was very young because it resem­bles galax­ies typ­i­cally found in the early uni­verse. But images from NASA’s Hub­ble Space Tele­scope show older stars within the galaxy lead­ing sci­en­tists to update their ideas. They now believe I Zwicky 18 was born about the same time as the Milky Way Galaxy and the Androm­eda Galaxy.

This galax­ian drag­on­fly, wings folded, rests deep in space. NASA’s Hub­ble Space Tele­scope clearly shows a pair of merg­ing, edge-on galax­ies called NGC 6670. Astronomers believe the two galax­ies have already had one close encounter with each other and are mak­ing a sec­ond pass. The galax­ies are just 50,000 light years apart. For com­par­i­son, our Milky Way Galaxy is 100,000 light-years wide and the near­est large galaxy to it is the Androm­eda Galaxy at two mil­lion light-years away.

A cos­mic spider-shaped neb­ula hides in a dark cor­ner of space. Astronomers look­ing toward the con­stel­la­tion Circi­nus with earth-based tele­scopes saw only a fuzzy, hourglass-shaped patch of light. But when they turned the dust-piercing, infrared light gath­er­ing NASA’s Spitzer Space Tele­scope at this spot in the sky, they dis­cov­ered a neb­ula bloom­ing with clus­ters of mas­sive young stars. Astronomers called it the “Black Widow Neb­ula.”
