Nearby Superbubble in the Night Sky
Description: A nearby superbubble discovered with the 100 m Green Bank Telescope (GBT) is shown as if we were able to see it with the naked eye in the night sky. A picture of the night sky taken from the NRAO Green Bank observatory site is overlaid by an optical…

Violent Milky Way's Halo HI (image 7)
Description: This is a false-color image showing the structure of the HI (neutral hydrogen) halo of the Milky Way near the Scutum spiral arm approximately 2 kpc above the Galactic disk. Brighter yellow corresponds to more and darker red to less hydrogen density.…

Violent Milky Way's Halo HI (image 6)
Description: This is a false-color image showing the structure of the HI (neutral hydrogen) halo of the Milky Way near the Scutum spiral arm approximately 2 kpc above the Galactic disk. Brighter yellow corresponds to more and darker red to less hydrogen density.…

Violent Milky Way's Halo HI (image 5)
Description: This is a false-color image showing the structure of the HI (neutral hydrogen) halo of the Milky Way near the Scutum spiral arm approximately 1 kpc above the Galactic disk. Brighter yellow corresponds to more and darker red to less hydrogen density.…

Violent Milky Way's Halo HI (image 4)
Description: This is a false-color image showing the structure of the HI (neutral hydrogen) halo of the Milky Way near the Scutum spiral arm approximately 1.5 kpc above the Galactic disk. Brighter yellow corresponds to more and darker red to less hydrogen…

Violent Milky Way's Halo HI (image 3)
Description: This is a false-color image showing the structure of the HI (neutral hydrogen) halo of the Milky Way near the Scutum spiral arm approximately 2 kpc above the Galactic disk. Brighter yellow corresponds to more and darker green to less hydrogen…

Violent Milky Way's Halo HI (image 2)
Description: This is a false-color image showing the structure of the HI (neutral hydrogen) halo of the Milky Way near the Scutum spiral arm approximately 2 kpc above the Galactic disk. Brighter yellow corresponds to more and darker green to less hydrogen…

Violent Milky Way's Halo HI (image 1)
Description: This is a false-color image showing the structure of the HI (neutral hydrogen) halo of the Milky Way near the Scutum spiral arm approximately 2 kpc above the Galactic disk. Brighter yellow corresponds to more and darker green to less hydrogen…

Hydrogen Emission from a 30 Myr Old Superbubble II
Description: A nearby superbubble recently discovered with the 100 m Green Bank Telescope (GBT) is shown as a false color image. Green color is neutral hydrogen detected by its 21 cm radio emission, purple -- ionized hydrogen detected by its optical emission,…
