They used the ALMA telescope to observe a slow outflow and a high speed jet from a newly forming star. These two streams appear misaligned and were apparently launched from different parts of the star-forming disk.

Scientists used the measured velocities of 44 globular star clusters to measure the mass of our home galaxy, the Milky Way.

There are at least 200 billion stars in our galaxy, and perhaps even a greater number of planets. Now a new study suggests there could be an additional 50 billion rogue planets, not orbiting any stars.

The red dwarf star TRAPPIST-1 – about 40 light-years away – has 7 Earth-sized exoplanets orbiting it. A new study puts limits on how many of those worlds have hazy or cloudy atmospheres.
