NASA reveals stunning image of giant 'cosmic smile'
New York Post • • science
Key Points:
- NASA showcased an image captured by the Hubble Space Telescope illustrating gravitational lensing, where a galaxy cluster appears to form a cosmic "smile" due to warped spacetime.
- The arcs, described as "smile lines," result from the bending of light by massive structures, allowing astronomers to magnify and study distant galaxies that would otherwise be too faint to observe.
- This effect also helps scientists map the distribution of dark matter within massive galaxy clusters, providing insight into the universe's unseen components.
- The featured galaxy cluster, SDSS J1038+4849, was originally imaged in 2015, with bright galaxies forming the "eyes" and gravitational lensing creating the arc-shaped "smile."
- The image and concept received enthusiastic reactions on social media, highlighting public fascination with gravitational lensing and its role in astronomy.
