Microlensing Event at OGLE-2013-BLG-0341 (Hubble Image)
Related Observations · NASA Science
A follow-up observation by NASA's Hubble Space Telescope shows a field containing a microlensing event that was captured by the Optical Gravitational Lensing Experiment (OGLE) in 2013. This provides an example of how a Hubble image could be used to analyze future microlensing events spotted by NASA's Nancy Grace Roman Space Telescope.
In gravitational microlensing, the gravity of a foreground object acts as a lens, magnifying and distorting the light of a background star when the two objects align in the sky.
About the data
These images were created with Hubble data from proposal: 17776 (S. Terry).

- Description
- Microlensed Exoplanet, Hubble Galactic Bulge Survey
- Constellation
- Sagittarius
- Distance
- The center of our galaxy is about 26,000 light-years away
- Instrument
- WFC3/UVIS
- Filters
- F606W, F814W
- Exposure dates

- Color
- These images were acquired by the Wide Field Camera 3 (WFC3/UVIS) instrument on NASA's Hubble Space Telescope . Several filters were used to sample varying wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Cyan: F606W and Orange: F814W
