How to Feed a Galactic Monster

This image shows the Slumgullion Landslide in southwestern Colorado. The central area above the highway moves almost an inch per day; the lower part moves much more slowly.

MIT researchers find that extratropical storm tracks — the blue regions of storminess in the Earth's middle latitudes — would change significantly with solar geoengineering efforts.

A composite image of the central region of our Milky Way galaxy, known as Sagittarius A. SOFIA found that magnetic fields, shown as streamlines, are strong enough to control the material moving around the black hole, even in the presence of enormous gravitational forces. This can help answer long-standing, fundamental questions about the galactic center region: why the star formation rate is significantly lower than expected and why our galaxy’s black hole is quieter than those in other galaxies. SOFIA data is shown in green (37 microns) and dark blue (25 and 53 microns). The light blue is from Herschel Space Observatory (70 microns) and the gray is from the Hubble Space Telescope.

Researchers at MIT, the University of Oklahoma, and elsewhere, with the help of citizen scientists, have identified a brown dwarf with a disk that is the youngest of its kind within about 100 parsecs of Earth. The brown dwarf, named W1200-7845 and depicted in this image, appears to have the kind of disk that could form planets.

Scientists Shed Light on Growth of Black Holes
