Image: Hubble captures cosmic cluster

The massive cluster Abell 3322 is featured in this image from the NASA/ESA Hubble Space Telescope, in which the galaxy 2MASX J05101744-4519179 basks in the center. This distant galaxy cluster is a cosmic leviathan that is ...

Radio observations inspect galaxy cluster Abell 1413

Using the LOw-Frequency ARray (LOFAR) and MeerKAT telescope, European astronomers have performed radio observations of a galaxy cluster known as Abell 1413. Results of the observational campaign, published August 1 in the ...

Video: The universe in a box: Preparing for Euclid's survey

ESA's Euclid mission will create a 3D-map of the universe that scientists will use to measure the properties of dark energy and dark matter and uncover the nature of these mysterious components. The map will contain a vast ...

The glittering, glitzy contents of the globular cluster NGC 6652 sparkle in this star-studded image from the NASA/ESA Hubble Space Telescope. The core of the cluster is suffused with the pale blue light of countless stars, ...

Webb spotlights gravitational arcs in 'El Gordo' galaxy cluster

A new image of the galaxy cluster known as "El Gordo" is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image, taken by NASA's James Webb Space Telescope, displays ...

Unexpectedly calm and remote galaxy cluster discovered

Astronomers have discovered the most distant "relaxed" galaxy cluster to date—the farthest cluster ever spotted that is not being disrupted by violent collisions with other clusters of galaxies. This finding is paving the ...

Image: Hubble views a galactic monster

The NASA/ESA Hubble Space Telescope has captured a monster in the making in this observation of the exceptional galaxy cluster eMACS J1353.7+4329, which lies about eight billion light-years from Earth in the constellation ...

Gravity and dark matter, a bond beyond distances

Isaac Newton formulated his theory of gravity as an action at a distance: a planet instantly feels the influence of another celestial body, no matter the distance between them. This characteristic motivated Albert Einstein ...
