NASA’s Webb Sees Galaxy Mysteriously Clearing Fog of Early Universe

Using the unique infrared sensitivity of NASA’s James Webb Space Telescope, researchers can examine ancient galaxies to probe secrets of the early universe. Now, an international team of astronomers has identified bright hydrogen emission from a galaxy in an unexpectedly early time in the universe’s history.

ESA Previews Euclid Mission’s Deep View of ‘Dark Universe’

With contributions from NASA, the mission is looking back into the universe’s history to understand how the universe’s expansion has changed.  The Euclid mission — led by ESA (European Space Agency) with contributions from NASA — aims to find out why our universe is expanding at an accelerating rate. Astronomers use the term “dark energy” […]

NASA Webb Wows With Incredible Detail in Actively Forming Star System

High-resolution near-infrared light captured by NASA’s James Webb Space Telescope shows extraordinary new detail and structure in Lynds 483 (L483). Two actively forming stars are responsible for the shimmering ejections of gas and dust that gleam in orange, blue, and purple in this representative color image.

NASA Telescopes Deliver Stellar Bouquet in Time for Valentine’s Day

A bouquet of thousands of stars in bloom has arrived. This composite image contains the deepest X-ray image ever made of the spectacular star forming region called 30 Doradus. By combining X-ray data from NASA’s Chandra X-ray Observatory (blue and green) with optical data from NASA’s Hubble Space Telescope (yellow) and radio data from the […]

Black Holes Can Cook for Themselves, Chandra Study Shows

Astronomers have taken a crucial step in showing that the most massive black holes in the universe can create their own meals. Data from NASA’s Chandra X-ray Observatory and the Very Large Telescope (VLT) provide new evidence that outbursts from black holes can help cool down gas to feed themselves. This study was based on […]

New Simulated Universe Previews Panoramas From NASA’s Roman Telescope

Astronomers have released a set of more than a million simulated images showcasing the cosmos as NASA’s upcoming Nancy Grace Roman Space Telescope will see it. This preview will help scientists explore a myriad of Roman’s science goals. “We used a supercomputer to create a synthetic universe and simulated billions of years of evolution, tracing […]

Newfound Galaxy Class May Indicate Early Black Hole Growth, Webb Finds

In December 2022, less than six months after commencing science operations, NASA’s James Webb Space Telescope revealed something never seen before: numerous red objects that appear small on the sky, which scientists soon called “little red dots” (LRDs).

How Many Black Holes Are Hiding? NASA Study Homes in on Answer

An effort to find some of the biggest, most active black holes in the universe provides a better estimate for the ratio of hidden to unhidden behemoths. Multiple NASA telescopes recently helped scientists search the sky for supermassive black holes — those up to billions of times heavier than the Sun. The new survey is […]
