One image tracks the same cosmic object across space and time. It's all down to a strange quirk of physics | BBC Sky at Night Magazine Light from little red dot RX1 is split into four images. Between the youngest and oldest image is about 130 years.

The hottest topic in #astronomy is what exactly the little red dots (#LRDs) hiding in #JWST images really are.

Visualization of galaxy cluster CL0025+1654, 4.5 billion light-years away. Yellow dots represent galaxies, while blue shows the mapped distribution of dark matter revealed through gravitational lensing. This Hubble Space Telescope image demonstrates how dark matter closely follows the distribution of luminous matter within the cluster.
