Magnifying Deep Space Through the ‘Carousel Lens’

Annotated Hubble Space Telescope image of the Carousel Lens, taken in two 10-minute exposures, one using an optical filter and another using an infrared filter.

The “L” indicators near the center (La, Lb, Lc, and Ld) show the most massive galaxies in the lensing cluster, located 5 billion light years away. Seven unique galaxies (numbered 1 through 7) – located an additional 2.6 to 7 billion light years beyond the lens – appear in multiple, distorted “fun-house mirror” iterations (indicated by each number’s letter index, e.g., a through d), as seen through the lens. (Credit: Credit: William Sheu (UCLA) using Hubble Space Telescope data.)

A newly discovered cluster-scale strong gravitational lens, with a rare alignment of seven background lensed galaxies, provides a unique opportuni...

Webb Spots Surprisingly Massive Galaxies in early Universe

Inching towards the Big Bang: The James Webb telescope peers deep into space and time
Inching towards the Big Bang: The James Webb telescope peers deep into space and time.

The James Webb Space Telescope has spotted six massive galaxies that emerged not long after the Big Bang, a study said Wednesday, surprising scientists by forming at a speed that contradicts our current understanding of the universe.

Since becoming operational last July, the Webb telescope has been peering farther than ever before into the universe’s distant reaches—which also means it is looking back in time.

For its latest discovery, the telescope spied galaxies from between 500 to 700 years million years after the Big Bang 13.8 billion years ago, meaning the universe was under five percent of its current age.

Webb’s NIRCam instrument, which operates in the near infrared wavelength invis...

Hubble Detects Ghostly Glow Surrounding Our Solar System

This artist’s illustration shows the location and size of a hypothetical cloud of dust surrounding our solar system. Astronomers searched through 200,000 images and made tens of thousands of measurements from Hubble Space Telescope to discover a residual background glow in the sky. Because the glow is so smoothy distributed, the likely source is innumerable comets – free-flying dusty snowballs of ice. They fall in toward the Sun from all different directions, spewing out an exhaust of dust as the ices sublimate due to heat from the Sun. If real, this would be a newly discovered architectural element of the solar system.

Red-Supergiant Supernova: Secrets of an Earlier Universe

Four images of supernova exploding
Panels A-D (clockwise from upper left) show several different stages of the supernova: the location of the host galaxy after the supernova faded, the three images of the host galaxy and the supernova at different phases in its evolution, the three different faces of the evolving supernova, and the different colors of the cooling supernova.

Detailed telescope images help scientists learn more about the Universe two billion years after the Big Bang. An international research team led by the University of Minnesota Twin Cities has measured the size of a star dating back 2 billion years after the Big Bang, or more than 11 billion years ago...
