The second- and fourth-most distant galaxies ever seen (UNCOVER z-13 and UNCOVER z-12) have been confirmed using the James Webb Space Telescope’s Near-Infrared Camera (NIRCam). They are shown here as near-infrared wavelengths of light that have been translated to visible-light colors.

James Webb telescope discovers 2 of the oldest galaxies in the universe

By Brandon Specktor published

The James Webb Space Telescope has discovered a cosmic 'peanut' and 'fluff ball' that happen to be two of the four oldest galaxies in the known universe.

James Webb telescope discovers 'Cosmic Vine' of 20 connected galaxies sprawling through the early universe

By Brandon Specktor published

The James Webb Space Telescope has discovered a massive chain of 20 galaxies in the early universe, raising questions about the formation of the largest structures in the cosmos.

The Crab Nebula. An oval nebula with complex structure against a black background. On the nebula’s exterior, particularly at the top left and bottom left, lie curtains of glowing red and orange fluffy material. Its interior shell shows large-scale loops of mottled filaments of yellow-white and green, studded with clumps and knots.

Space photo of the week: James Webb telescope finds a secret at the Crab Nebula's heart

By Jamie Carter published

The James Webb Space Telescope has revealed the most detailed image so far of the Crab Nebula, a gorgeous supernova remnant of a star that exploded 1,000 years ago.

James Webb telescope uncovers mysterious Milky Way 'twin' in the early universe

By Sharmila Kuthunur published

A Milky Way doppleganger discovered in the early universe suggests some key physical ingredient is missing from cosmological models.

Researchers using NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) have discovered a high-speed jet stream sitting over Jupiter’s equator, above the main cloud decks. At a wavelength of 2.12 microns, which observes between altitudes of about 12-21 miles (20-35 kilometers) above Jupiter’s cloud tops, researchers spotted several wind shears, or areas where wind speeds change with height or with distance, which enabled them to track the jet.

James Webb telescope spots enormous jet stream faster than a Category 5 hurricane on Jupiter

This illustration shows one possible scenario for the hot, rocky exoplanet called 55 Cancri e, which is nearly two times as wide as Earth. New data from NASA Spitzer Space Telescope show that the planet has extreme temperature swings.

Mysterious signals from 'hell planet' 40 light-years from Earth could finally be solved by James Webb Space Telescope

By Paul Sutter published

The hellish super-Earth '55 Cancri e' may be constantly losing and re-growing its atmosphere, a new study of the planet's strange transit signals suggests.

A 2 week observation through the optic eye of the Chandra X-Ray Observatory revealed this sturning explosion occurring in the super massive black hole at the Milky Way's center, known as Sagittarius A or Sgr A*. Huge lobes of 20-million degree Centigrade gas ( red loops in image) flank both sides of the black hole and extend over dozens of light years indicating that enormous explosions occurred several times over the last 10 thousand years.

Mysterious 'fountain of youth' near Milky Way's central black hole is full of newborn stars that shouldn't exist
