This first light, as it's called, shows that all of the spacecraft's systems are working just as expected. "Based on the images we are seeing, we can now say that the instrument team nailed it," Jamie Bock, SPHEREx’s principal investigator at Caltech and NASA's Jet Propulsion Laboratory in California, said in a statement.

Explore how the Webb telescope reveals a massive black hole from the early universe living in a dormant state for most of its life.

Webb first observed the region called Sagittarius C in 2023. Now researchers are now using those observations to study star formation in the wider area around the center of the Milky Way, known as the Central Molecular Zone.

The rare cosmic phenomenon, called an Einstein ring, occurs when massive objects can bend light due to their gravitational influence. The post James Webb Space Telescope image shows one galaxy hiding behind another appeared first on Talker.

Recent observations from the James Webb Space Telescope revealed a decrease in the asteroid's size, adjusting it from previously estimated dimensions of 131-295 feet (40-90 meters) to 174-220 feet (53-67 meters).

Webb has filled in many gaps left by Voyager 2, the only spacecraft to visit the planet. In 2022, the telescope captured Neptune's ghostly rings and revealed a band of clouds around a known vortex at the planet's south pole for the first time.

NASA's James Webb Space Telescope (JWST) has snapped a spectacular image of a "cosmic tornado" being burped out from a baby star. The image reveals an outflow of hot gas from a newborn star — known as a Herbig-Haro object — situated about 625 light-years from Earth in the constellation Chamaeleon.

A newborn star, a blast of glowing gas, and a distant spiral galaxy — all caught in one stunning snapshot by the James Webb Space Telescope. This rare cosmic overlap forms a swirling, colorful image that blends science with art,

The NASA James Webb Space Telescope captured a stunning image of an Einstein ring, an optical phenomenon created by gravitational lensing. This rare s
