The dwarf galaxy problem
... are shown in red with big features labelled. The red dappling shows the noise in the cube. Figure 4 - All of the discrete clouds detected. The black outline shows the gas disk of M33. All of the clouds are colour coded according to their velocity...

Bridge between the Magellanic Clouds discovered
... these regions find it easy to leave the satellite and begin orbiting the host. As more stars leave the satellite, they leave a trace on the sky that reveals the satellite's orbit. "Stellar streams around the Clouds were predicted but never observed...

First glimpse at how gravity effects star formation
... of four filaments converging on a central hub, have captured the effects of gravity on ammonia gas moving within the cloud to show how the swirling motion of gas aids in the star formation process. It has been known for some time that stars...

Unstoppable monster galaxy puzzles and enlightens astronomers
... overly active star formation is that the clouds throughout the galaxy are very unstable, which is not normally the case. Gas clouds keep in equilibrium as long as the inward force of gravity is matched by the outward force of pressure. Once gravity...

Cassini observations open up Saturn’s atmosphere
... condensation of water), and gases and fresh cloud material dredged up from the deeper atmosphere. Once at the cloud tops, the new material is blown around the planet by the prevailing winds, creating a storm system that evolves from a single white...

Does a second black hole lurk near the centre of the Milky Way?
... and a compact but low density component with a very wide velocity dispersion of 100 km/s. As no holes were observed in the cloud and X-ray and infrared observations did not find any corresponding compact objects, a wide velocity dispersion...
