Starting out our starry alphabet is the nebula near Pismis 24. Harsh winds from hot, new stars have hollowed out an “A” in this image from NASA’s Hubble Space Telescope.
Newborn stars are tucked away in their baby blanket of gas and dust in this image of Rho Ophiuchus from NASA’s Spitzer Space Telescope.
Like a hollowed out ornament, NGC 6357 glows red in the constellation Scorpius. Or, maybe, what I see in this NASA Hubble Space Telescope image is a Christmas tree reaching for the stars of the open star cluster Pismis 24.
The Hubble Space Telescope shows us another example of how our Sun might die in 5 billion years. The “Ant Nebula, ” or Menzel 3, shows two glowing bubbles coming out from the dying star. Astronomers are most curious about the equal shape of the bubble on either side of the star. This symmetry offers scientists a chance to come up with many different ideas on the cause.
