Clouds Dominate the Galactic Halo

Using the exquisite sensitivity of the National Science Foundation’s Green Bank Telescope, astronomer Jay Lockman of the National Radio Astronomy Observatory in Green Bank, West Virginia, has produced the best cross-section ever of the Milky Way Galaxy’s diffuse halo of hydrogen gas.

Aging Star is a Giant Water Fountain

Astronomers using the National Science Foundation’s Very Long Baseline Array (VLBA) radio telescope have found that an aging star is spewing narrow, rotating streams of water molecules into space, like a jerking garden hose that has escaped its owner’s grasp.

Supermassive Black Hole Mimics Smaller Cousins

Scientists have caught a supermassive black hole in a distant galaxy in the act of spurting energy into a jet of electrons and magnetic fields four distinct times in the past three years, a celestial take on a Yellowstone geyser.

Binary Stars ‘Flare’ With Predictable Cycles

Astronomers have completed a 5-year campaign to monitor continuously radio flares from two groups of binary star systems. This survey is of special interest because it provides evidence that certain binary star systems have predictable activity cycles like our Sun.
