Our current best radial velocities are precise to about 1m/s. How do we make the step towards achieving 10cm/s precision?
How many spiral arms does the Milky Way have? You might be surprised to learn that astronomers are still not completely sure.
Much of what we know today about exoplanets is due to the success of the radial velocity method. Where does it stand now? What is its future?
70,000 years ago, a binary star passed through the outskirts of the Oort Cloud–was it the closest known stellar encounter?
The Kepler Space Telescope was the workhorse of exoplanet discovery until its second reaction wheel failed, rendering it incapable of continuing its original mission. Now, Kepler is back in the game of planet hunting.
Are more massive stars more likely to have planets? Read on to find out…
