Milky Way Ransacks Nearby Dwarf Galaxies, Stripping All Traces of Star-Forming Gas

October 15, 2014
Astronomers using the National Science Foundation’s Green Bank Telescope (GBT) in West Virginia, along with data from other large radio telescopes, have discovered that our nearest galactic neighbors, the dwarf spheroidal galaxies, are devoid of star-forming gas, and that our Milky Way Galaxy is to blame… Read More

  • Image at 7 mm wavelength of the dusty disk around the star HD 169142 obtained with the Very Large Array (VLA) at 7 mm wavelength. The positions of the protoplanet candidates are marked with plus signs (+) (Osorio et al. 2014, ApJ, 791, L36). The insert in the upper right corner shows, at the same scale, the bright infrared source in the inner disk cavity, as observed with the Very Large Telescope (VLT) at 3.8 micron wavelength (Reggiani et al. 2014, ApJ, 792, L23).

Alma

  • This artist’s impression shows the dust and gas around the double star system GG Tauri-A. Researchers using ALMA have detected gas in the region between two discs in this binary system. This may allow planets to form in the gravitationally perturbed environment of the binary. Half of Sun-like stars are born in binary systems, meaning that these findings will have major consequences for the hunt for exoplanets.

  • ALMA image of the distribution of the organic molecule HNC in the upper atmosphere of Saturn's moon Titan. The denser, brighter concentrations are shown near the moon's north and south poles. Their shifted, off-axis locations were unexpected and could help researchers better understand Titan's complex atmospheric processes. The globe outline represents Titan's orientation at the time of the observations.
