Two NASA space telescopes jointly observed a microlensing event, when a distant star brightens due to the gravitational field of at least one foreground cosmic object.
LATEST IMAGE
Astronomers were surprised to see these data from NASA's Spitzer Space Telescope in January 2013, showing a huge eruption of dust around a star called NGC 2547-ID8. In this plot, infrared brightness is represented on the vertical axis, and time on the horizontal axis.
