Eight of Space

In 1987, astronomers wit­nessed a bril­liant explo­sion. A mas­sive star exploded, shin­ing with more light than an entire galaxy. In a span of months it was gone. With the help of NASA’s Hub­ble Space Tele­scope, astronomers “re-found” SN 1987A hid­den in a back­drop of glit­ter­ing stars and shim­mer­ing wisps of gas.

Fireworks in D

The let­ter D is out­lined in this celes­tial fire­works dis­play. The col­or­ful fil­a­ments seen in this NASA Hub­ble Space Tele­scope image of N49 are all that’s left of a super­nova explo­sion that took place thou­sands of years ago in the Large Mag­el­lanic Cloud. This super­nova rem­nant is called N 49, or DEM L 190. Inside these sheets of glow­ing star debris lies a pow­er­ful, spin­ning neu­tron star called a pul­sar. Pul­sars give off reg­u­lar pulses of energy like the tick­ing of a very pre­cise clock. After the super­nova blows off the outer lay­ers of the star, it col­lapses under its own grav­ity. The star col­lapses so much that the pro­tons and elec­trons spin­ning around the atoms of the star com­bine to form neu­trons. A neu­tron star is very dense. Imag­ine our entire Sun packed into an area of just 20 kilo­me­ters (12 miles) in diam­e­ter! Grav­ity is very strong on a neu­tron star. On Earth, a spoon­ful of neu­tron star mate­r­ial would weigh bil­lions of tons. The mag­netic field of N 49 is super strong, tril­lions of times stronger than Earth’s, putting it in spe­cial class of bizarre celes­tial objects called magnetars.

Curling C

Galaxy inter­ac­tions cre­ate all sorts of curls and odd shapes. In this NASA Hub­ble Space Tele­scope image of UGC 4881, the let­ter ‘C’ spi­rals out in deep space.

Angry Fish

Acknowl­edg­ment: Y.-H. Chu and R. M. Williams (UIUC)

To me, this image of what hap­pens after a super­nova blows up, has always looked like a piranha or some sort of angry fish. This image of N 63A from NASA’s Hub­ble Space Tele­scope; that’s what astronomers call it, used to be a huge star, many times big­ger than the sun. Stars like N 63A have vio­lent lives. They live quickly and then explode with force that for a short time they out­shine entire galaxies.

Starship contrail

A del­i­cate rib­bon of gas floats through this image from NASA’s Hub­ble Space Tele­scope. Is it a con­trail left by a star­ship bar­rel­ing through the area? Actu­ally, this rib­bon of gas is the thin edge of the super­nova rem­nant SN 1006 in our galaxy that exploded more than 1,000 years ago.

Nebular Octopus

An green octo­pus hides in the cor­ner of this image of a neb­ula in the Large Mag­el­lanic Cloud. Home to some of the most bril­liant, most mas­sive stars known to astronomers, Hodge 301 is an active star­burst region.

The Little Man

J. Hester/Arizona state Uni­ver­sity NASA

Explore the image of Eta Cari­nae and you’ll see the lit­tle man, or homuncu­lus, astronomers saw in their tele­scopes 150 years ago. Eta Cari­nae is a star on the brink of destruc­tion. In 1841, the blue hypergiant-star sud­denly became the sec­ond bright­est star in the night sky. Dur­ing the next 20 years, Eta Cari­nae, or Eta Car, ejected more mass than our Sun. Then the star faded. When astronomers searched out the star, they found the Homuncu­lus Neb­ula. In Latin, homuncu­lus means “lit­tle man.” Share with us the shapes and sto­ries you see in this neb­ula.

Monkey Face

Do you see a mon­key face look­ing up? Or sparks and smoke left over from a fire­works dis­play?
