Exoplanetary Scratchpad

[SysBP Img]

A planet detected with microlensing measured to be one of the furthest ones known (13,000 ly), inwards, towards the center of the galaxy. It's distance was able to be determined with the help of Spitzer, whose orbit trails the Earth significantly, which is able to simultaneously observe the microlensing event and determine its distance with the delay of the event compared with earth based observations (a blip was detected with Spitzer 20 days before than from Earth). This is important so that astronomers can determine if planets are more common in the center of the galaxy. Once distance was determined, its mass could be determined, which was about half Jupiter's. The planet orbits a star with 0.7 solar masses at a distance of 3.1 AU.

My ThoughtsEdit

Wow, it's cool that we're able to do parallel observations with Spitzer, which is quite a bit away from Earth. Also cool that we're trying to map planet population distributions across the galaxy. That map that showed where the known planets are was pretty neat, with a nice sphere around the sun, a nice view into the direction of Kepler's gaze, and then several dots along a line towards the galaxy center for those found with microlensing.
