Fleming 1 is a rare planetary nebula enclosing a binary pair of white dwarf stars (typically these shells of gas surround only one white dwarf). The fast orbit of these stars creates two nearly symmetric jets that make Fleming 1 atypical.

Whether big or small, stars mostly form the same way; stellar gasses accumulating and slowly condensing until a fusion reaction is started. However, stars can die in different way, from super nova explosions to slow, steady decay.

Researchers had thought disks like our own Milky Way had been static for the last 8 billion years.
19 October 2012, 02:04 PM ET
A study of 544 star-forming galaxies observed by the Keck and Hubble telescopes shows that disk galaxies like our own Milky Way unexpectedly reached their current state long after much of the universe's star formation had ceased.

NASA turned its Chandra X-Ray Observatory to planetary nebulas in our solar neighborhood (within 5000 light years). These objects are the remains of red giant stars that shed most of their mass as they condense into white dwarfs.

A companion star pushing through expelled dust and gas around a red giant star created a spiral structure.
10 October 2012, 12:02 PM ET
Astronomers using the Atacama Large Millimeter Array have discovered a surprising spiral structure and spherical shell surrounding the red giant star R Sculptoris. The shape was probably caused by a hidden companion star orbiting the red giant.

What a difference 50 years can make. The European Southern Observatory got its start using giant film slides – blurry and inexact by modern standards. Today, high tech digital telescopes and sensors can capture dramatically more detail.
04 October 2012, 01:37 PM ET
These shape-shifting galaxies have taken on the form of a giant mask. The icy blue eyes are actually the cores of two merging galaxies, called NGC 2207 and IC 2163, and the mask is their spiral arms in this cool space wallpaper.
