Planet Hunting Techniques: Microlensing

Posted by

Astronomers can discover a planet not by noticing the planet’s gravitational effects on its parent star but rather on a star much farther away.

When one celestial object passes in front of another from our point of view, the closer object’s gravity can bend and magnify the light of the more distant object, causing the distant object to appear brighter than normal for a short time. This phenomenon is called gravitational microlensing.

For example, if a closer star passes in front of a farther star, the farther star will appear temporarily brighter and then return to its normal brightness after the closer star has passed.

But if, by chance, the closer star is accompanied by an unseen planet, the farther star’s brightness will increase a second time as the planet passes in front of it.

By watching for a distant star’s brightness to intensify twice, astronomers can find out whether the closer star has a secret traveling companion.

Moonrise: The Surprisingly Diverse Array of Moons in our Solar System
Dr. Bonnie Meinke, Space Telescope Science Institute

Earth’s Moon is so familiar to us, yet there are hundreds of other moons in our solar system that still remain exotic. Take a journey from our Moon to the weird and wonderful collection of moons across interplanetary space. Explore volcanoes, oceans, and clouds that make these distant worlds much more recognizable than one might have guessed. And consider how these familiar geologic features could create ideal conditions for life to take hold and flourish!

Host: Dr. Frank Summers

Recorded live on May 6, 2014 at the Space Telescope Science Institute in Baltimore, MD, USA
