Acting Programme Scientist for the European Extremely Large Telescope (E-ELT), and host of Hubblecast, European Southern Observatory (ESO)
Joe Liske, host of Hubblecast, is also the top scientist on the European Southern Observatory’s European Extremely Large Telescope (E-ELT), now under construction on a Chilean mountaintop. “Dr. J” tells us what this largest ever telescope will help us discover. Emily Lakdawalla has updates on the Akatsuki and Chang’e missions. Bill Nye shares his thoughts about the latest SpaceX launch to the International Space Station. Bruce Betts looks back at the Huygens lander on Saturn’s moon Titan for this week’s What’s Up.
European Extremely Large Telescope deploying lasers for adaptive optics
The E-ELT will make extensive use of adaptive optics to achieve images of remarkable sharpness. In this artist’s view the future 39-meter telescope is shown using lasers to create artificial stars high in the atmosphere. These are used as part of the telescope’s sophisticated adaptive optics system to remove much of the blurring effect of the Earth’s atmosphere.
Besides Galileo (the man, not the spacecraft) who was the first person to discover a moon circling another planet? (Not Earth’s moon, but you might earn extra points if you tell us who discovered that moon, too. Also, a Nobel prize.)
The answer will be revealed next week.
Question from the week before:
How many rockets carried humans into orbit in 2014?
