A bright surprise in the early universe: new discoveries from the James Webb Space Telescope

Among the impressive achievements of the telescope is the detection of very early galaxies, which developed only about 300 million years after the Big Bang

NASA's SPHEREx Satellite: Exploring the Universe in 102 Infrared Colors 

"This is the first mission to view the entire sky in so many colors," said Jamie Bock, principal investigator of SPHEREx, which operates jointly at NASA's Jet Propulsion Laboratory (JPL) and Caltech.

Heavenly beauty: discover a "ring galaxy" that challenges expectations

The "ring galaxy" classification is reserved for unique galaxies with a circular ring of gas and star formation, much as spiral arms are seen, but completely detached from the galactic nucleus - or even without a nucleus at all.

NASA's Chandra X-ray Observatory Celebrates 25 Years With Impressive Cosmic Images

Since its launch in 1999, Chandra has helped unravel cosmic mysteries, supported the research of thousands of astronomers, and maintained its status as a cornerstone of astrophysical research.
An international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope has directly imaged an extrasolar planet about 12 light-years from Earth. Although there were hints that the planet existed, it was not confirmed until Webb photographed it. The planet is one of the coldest exoplanets observed so far.

Webb photographs a cold extrasolar planet 12 light years away

The mass of the planet, named Epsilon Indi Ab, is about three times that of Jupiter and it orbits the K-type star Epsilon Indi A, which is about the age of the Sun but is slightly
For the first time, a phenomenon that astronomers had long hoped to photograph directly has been captured by the NASA/ESA/CSA James Webb Space Telescope's Near Infrared Camera (NIRCam).

long image captionThis is part of the Evolution of the Universe Early Science Survey (CEERS), consisting of several near-infrared points from the NIRCam (Near Infrared Camera) camera on the James Webb Space Telescope. These observations are being made in the same region studied by the Hubble Space Telescope, known as the Extended Groth Belt. Arrows showing the directions north and east show the direction of the image in the sky. It should be noted that the relationship between north and east in the sky (as seen from below) is reversed compared to the half directions on the map of the earth (as seen from above). The image shows invisible near-infrared wavelengths converted to visible colors. The color key shows which NIRCam filters were used to collect the light. The name color of each filter is the visible color that represents the infrared light passing through that filter. The barrel ruler is marked with arc-seconds which are a measure of angular distance in the sky. One arc-second is equal to an angular measurement of 1/3600 of one degree. There are 60 arc-minutes in a degree and 60 arc-seconds in an arc-minute. (The full moon has an angular diameter of about 30 arc-minutes.) The actual size of an object that covers one arc-second in the sky depends on its distance from the telescope.

The James Webb telescope reveals: galaxies in the early universe have a long and flat shape

The first galaxies were much less developed than the spiral and spherical galaxies that exist today, which are actually the result of mergers, both because of the stage of development but also because of the conditions that prevailed at the time
This image taken by the Hubble Space Telescope shows Aram-Mador 2105-332, a unique galaxy system in the Microscope Group. It is known for its emission line galaxies, which indicate vigorous star formation.

A star exploding is a dramatic event, but the debris the star leaves behind can be even more dramatic. A new mid-infrared image from the James Webb Space Telescope provides one stunning example. It shows the remains of the supernova Cassiopeia A (Cas A), created by a stellar explosion 340 years ago. The image shows bright colors and complex structures. Cas A is the youngest known remnant of a massive exploding star in our galaxy, offering astronomers an opportunity to understand the star's death process. Image credit: NASA, ESA, CSA, D.

Two of the most distant galaxies ever seen have been revealed in Webb Space Telescope images of the outer regions of the giant galaxy cluster Abell 2744. The galaxies are not inside the cluster, but many billions of light-years behind it. The galaxy shown in the top image in the center was extracted from the image on the left. It existed only 450 million years after the big bang. The galaxy shown in the lower center image is drawn from the image on the right. It existed 350 million years after the big bang. Both galaxies appear to be very close in time to the Big Bang that occurred 13.8 billion years ago. These galaxies are tiny compared to our Milky Way. Webb Space Telescope photo, ESA/NASA

Webb discovered the oldest galaxies, their age and properties surprised astronomers

One of these galaxies is observed as it appeared about 300 million years after the Big Bang and shines much brighter than expected. This figure now makes researchers estimate that the first galaxies were formed 100 million years after the Big Bang

The computer of the space telescope 'Hubble' is still disabled - NASA is trying new strategies to solve the problem

NASA is taking additional steps to investigate the malfunction that happened to the computer of the Hubble space telescope that began on June 13 and caused the suspension of scientific observations. At the same time as the investigation, NASA is looking at indirect ways to activate the backup hardware
The Hubble Space Telescope was deployed on April 25, 1990 from the high-redundancy space shuttle Discovery. Hubble's location outside the distortions of the atmosphere gives it an unfettered view of stars, planets, and galaxies out to a distance of more than 13.4 billion light-years.
