James Webb telescope finds ancient galaxy larger than our Milky Way, and it's threatening to upend cosmology

By Ben Turner published

Astronomers believe the first galaxies formed around giant halos of dark matter. But a newly discovered galaxy dating to roughly 13 billion years ago mysteriously appeared long before that process should have occurred.

James Webb telescope makes ultra-rare detection of 2 planets orbiting dead stars

By Robert Lea published

The James Webb Space Telescope has detected two alien planets orbiting white dwarfs, the collapsed husks of once-mighty stars. The discovery offers a hint of what our solar system will look like after the sun's eventual demise.

The Event Horizon Telescope Collaboration has released new images of M87* from observations taken in April 2018, one year after the first observations in April 2017. The new observations in 2018, which feature the first participation of the Greenland Telescope, reveal a familiar, bright ring of emission of the same size as we found in 2017. This bright ring surrounds a dark central shadow, and the brightest part of the ring in 2018 has shifted by about 30º relative from 2017 to now lie in the 5 o’clock position.

Right again, Einstein: New snapshot of 1st black hole to be photographed confirms relativity

An image of a young star-forming region filled with wispy blue, grey, green, and red nebulosity that is brightest towards the centre and fainter towards the edges, especially in the top left corner and on the right side. Thousands of stars are seen sprinkled across the field, concentrated towards the centre, and the brightest stars show the eight spikes due to diffraction that are characteristic of Webb images.
