What a spectacle! 🧐
In the constellation Draco, almost nine billion light-years away, a massive galaxy helps astronomers see its distant neighbors in this image captured by NASAHubble.
The behemoth galaxy in the center of this image warps the light of galaxies behind it, making the light appear bent as if by a lens: a phenomenon known as gravitational lensing. An important consequence of this distortion? Magnification – which can help astronomers study distant galaxies by acting as a vast natural telescope which magnifies objects that would otherwise be too faint or distant to see.
Hubble’s sensitivity and high resolution allows it to see faint and distant gravitational lenses that cannot be detected with ground-based telescopes, whose images would be blurred by the Earth’s atmosphere.
Image Description: A cluster of large galaxies, surrounded by various stars and smaller galaxies on a dark background. The central cluster is mostly made of bright elliptical galax...
