We see an array of twinkling yellow, red, and blue galaxies stretched across space in a way that is reminiscent of Christmas lights

James Webb telescope reveals gargantuan 'Mothra' star in most colorful image of the universe ever taken

By Jamie Carter published

The James Webb and Hubble space telescopes have combined forces to image a cluster of galaxies 4.3 billion light-years away in one of the most colorful pictures of the universe ever taken.

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.

James Webb telescope finds an 'extreme' glow coming from 90% of the universe's earliest galaxies

By Ben Turner published

The universe's early galaxies are way brighter than they should be. The James Webb Space Telescope's discovery of brightly glowing gas around 90% of primordial galaxies may explain why.

Universe's oldest X-ray-spitting quasar could reveal how the biggest black holes were born

By Robert Lea published

The newly identified quasar, observed 13.7 billion light-years away by the James Webb Space Telescope and Chandra X-ray Observatory, could be an example of a heavy black hole "seed" in the early universe.

Black Holes
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.

Exoplanets
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

By Briley Lewis published

New James Webb Space Telescope observations might be able to explain why clusters of young stars keep turning up near the Milky Way’s central black hole.

James Webb Space Telescope spots dozens of physics-breaking rogue objects floating through space in pairs

By Ben Turner published

Astronomers spotted Jupiter-mass binary objects (JUMBOs) in the Orion constellation, and they don't know how the objects formed.
