Gravitational Lensing By A Black Hole
This illustration reveals how the gravity of a black hole warps space and bends the light of a distant star behind it. A black hole is the crushed remnant of a massive star that exploded as a supernova. The black hole traps light due to its intense gravitational field, hence it cannot be seen directly. The black hole distorts the space around it, which warps images of stars lined up almost directly behind it. This offers telltale evidence for the existence of lone black holes wandering our galaxy. The light from a background star is deflected and brightened by the black hole's intense gravitational field. The Hubble Space Telescope goes hunting for these black holes by looking for distortion in starlight as the black hole drifts in front of background stars.

Illustration of an Isolated Black Hole
This is an illustration of a close-up look at a black hole drifting through our Milky Way galaxy. The black hole is the crushed remnant of a massive star that exploded as a supernova. The surviving core is several times the mass of our Sun. The black hole traps light due to its...
Microlensing Black Hole
The star-filled sky in this Hubble Space Telescope photo is located in the direction of the Galactic center. The brightness of stars are monitored to see if any change in apparent brightness is made by a foreground object drifting in front of them. The warping of space by the...
Time-Lapse Look at Microlensing from a Black Hole
This is a time-lapse of a set of four Hubble Space Telescope photos that capture the gravitational effects of an invisible black hole drifting through our galaxy. Because a black hole doesn't emit or reflect light, it cannot be directly observed. But its unique thumbprint on the...
