Black-Hole-Powered Jets Forge Fuel for Star Formation

Published on 14/02/2017 

Composite image showing how powerful radio jets from the supermassive black hole at the center of a galaxy in the Phoenix Cluster inflated huge "bubbles" in the hot, ionized gas surrounding the galaxy (the cavities inside the blue region imaged by NASA's Chandra X-ray observatory). Hugging the outside of these bubbles, ALMA discovered an unexpected trove of cold gas, the fuel for star formation (red). The background image is from the Hubble Space Telescope.

IMAXT: imaging and molecular annotation of xenografts and tumors

To fully understand cancer, scientists need to know everything about a tumour – what types of cells are in it, how many there are, what they are doing and where they are located in the tumour. Having such a detailed picture of a tumour would allow scientists and doctors to develop new ways to diagnose and treat the disease, and new ways to stop it spreading and coming back.

The dusty disc surrounding the star TW Hydrae exhibits circular features that may signal the formation of protoplanets. Cambridge astronomer Giovanni Rosotti is one of a team of astronomers led by LMU astrophysicist Barbara Ercolano who argue that the innermost feature actually points to the impending dispersal of the disc.
