This is the Oldest Known Galaxy Ever Photographed

The James Webb Space Telescope (JWST) has been busy peering into the distant reaches of the Universe, otherwise known as the "Cosmic Dawn." This period when the Universe was only a few hundred million years old is a treasure trove of information about how galaxies evolved when the Universe was very young.

NASA Develops Tiny Yet Mighty 36-Pixel Sensor

While NASA's James Webb Space Telescope is helping astronomers craft 122-megapixel photos 1.5 million kilometers from Earth, the agency's newest camera performs groundbreaking space science with just 36 pixels. Yes, 36 pixels, not 36 megapixels.

Ghostly Stellar Tendrils of the Vela Supernova Remnant

The Detail in This New 1.3-Gigapixel Photo of a Supernova is Incredible

Using the remarkable 570-megapixel Dark Energy Camera (DECam), astronomers have made a 1.3-gigapixel image of the ghostly Vela Supernova Remnant. The beautiful, detailed, and colorful image is the largest DECam image ever at 35,786 by 35,881 pixels, putting even the highest-resolution medium-format interchangeable lens cameras to shame.

The James Webb Space Telescope captures an image of NGC 1559 as part of the PHANGS collaboration. It is the Webb Picture of the Month for February 2024.

A Stunning, Lonely, and Fiery Galaxy Is a Treasure Trove of Data

As scientists continue to use the James Webb Space Telescope (JWST) to do incredible things, like find the first direct evidence of a neutron star in a nearby supernova remnant, it also generates many beautiful images that are easy for anyone to appreciate. That's where the monthly Webb Picture of the Month comes in. This month's new photo is of the barred spiral galaxy NGC 1559.

See the Sun’s Explosive Energy Captured Across Extreme Wavelengths

The Sun has been very active so far this month, with powerful sympathetic solar flares dazzling scientists and viewers alike and recent X-class flares making many wonder about communications network integrity. NASA's Solar Dynamics Observatory (SDO) constantly monitors the Sun and captures the recent powerful solar flares in exquisite detail across multiple wavelengths.

Webb Can See Far Enough to Test Theories of Dark Matter

The Hubble Space Telescope (HST) upended beliefs about the fundamental nature of the Universe, delivering evidence that the Universe was not slowing down, as gravity seemingly implied it must be, but expanding. 25 years later, the James Webb Space Telescope (JWST) can help scientists make another breakthrough.

NASA Hubble Picture of the Week ESO 245-5 irrregular galaxy

Hubble’s New Photo Shows the Immense Scale of Galaxies

The Hubble Space Telescope's new Picture of the Week shows a remarkably dense field of stars. However, what at first glance looks like just a field of stars, spread somewhat irregularly through the frame, the photo shows a considerable portion of a galaxy.

Webb surfs the cosmos

Webb Finds That Many Old, Distant Galaxies Look Like Surfboards

While the James Webb Space Telescope has been busy helping scientists solve some of the greatest mysteries of the early Universe, the powerful telescope has also found that many distant galaxies have flattened oval disk and tube-like shapes, unlike the spiral and elliptical structures that are more typically seen in closer galaxies.

Webb helps scientists answer one of the most persistent questions about the nature of the early Universe.

Webb Answers One of the Early Universe’s Biggest Questions

While the James Webb Space Telescope (JWST) has delivered many beautiful images, its primary mission is to probe the early Universe and help humanity solve some of the most significant questions it faces. Webb has delivered on this promise by revealing, for the first time, what is in the local environment of galaxies in the very earliest days of the Universe.
