A view from cameras on board the Orion spacecraft as it climbs to orbit, powered by the SLS (Space Launch System) rocket following a 6:35 p.m. EDT liftoff on April 1, 2026. Included is the jettison of the solid rocket boosters that propelled Orion for the first two minutes of flight, and the jettison of the spacecraft adapter jettison panels, which protect the spacecraft's solar array wings during ascent.

To get pics this detailed, you have to be CLOSE. A telephoto lens from miles off isn't enough. But that distance would severely injure any human. What's the solution? Pre-placed cameras and sound activated triggers.

A colourful field of stars sprinkled across purple ionised gas and redder dust. The main cluster of stars is seen in a cavity to the upper right, while a very bright source surrounded by more gas and dust is seen in the lower left corner, with the characteristic six bright spikes due to diffraction in the optics of JWST.

• UF researchers used the James Webb Space Telescope to capture visually striking images of the W51 star-forming region.
• The telescope allowed them to see through dust clouds and observe atoms and molecules that are invisible at other wavelengths.
• Young massive stars are generally poorly understood, and the telescope allowed the team to study how these stars interact with their surroundings.

A team of University of Florida researchers used the James Webb Space Telescope to capture photos of a star-forming region known as W51 with never-before-seen clarity and resolution. The long wavelengths of JWST’s infrared technology allowed astronomers to see the stars clearly and show what was previously hidden. Stars in the W51 region are very young and massive, and using the telescope gave the team the ability to view the early stages of star formation.

The telescope’s infrared technology revealed that the stars in the area started forming relatively recently, roughly within the past million years, and are still forming.

This isn’t the first time this region has been photographed and observed. But it may as well be.

Before gaining access to this technology, these stars were difficult to see. They are still wrapped in the dust of their birth environment, which obscured the view provided by most other telescopes.

The telescope revealed young stars, including those still growing to their birth weight, that couldn’t be seen before and atoms and molecules that are invisible at other wavelengths.

“With optical and ground-based infrared telescopes, we can’t see through the dust to see the young stars,” said Adam Ginsburg, Ph.D., a professor of astronomy at UF. “Now we can.”

With the region being host to massive young stars, doctoral candidate Taehwa Yoo said the telescope gave the team the opportunity to learn more about the formation of these kinds of stars, which are poorly understood compared to low-mass stars.

Better understanding high-mass stars is extremely important. They interact with neighboring gas and affect nearby star formations, including emitting radiation that heats up their surroundings. The colorful images from JWST show this radiation interacting with the giant cloud.

Webb captured this new image of galaxy Messier 58, in both the near and mid-infrared, as part of a treasury of 55 massive, star-forming galaxies. The data on the properties of these galaxies, and the stars within them, will add valuable insight to our picture of how galaxies grow and evolve over cosmic time.

M58 is a barred spiral galaxy located about 68 million light years away from Earth and one of the brightest galaxies in the Virgo Cluster. Compared with other spiral galaxies, its core appears dim in visible light and contains a high rate of star formation, especially within a small and unusual ring around the nucleus of the galaxy. In the infrared, more details of this region emerge.

Image description:

Webb’s image of M58 shows a face-on spiral galaxy anchored by its bright central region, which has a light blue haze that takes up about a quarter of the view. In this circular core is the brightest blue area. Spiral arms made of stars, gas, and dust also start at the center, starting at the brightest point. The spiral arms extend to the edges, rotating counterclockwise. The arms of the galaxy are largely orange, ranging from dark to bright orange​

The image at right is a composite view from NASA’s Hubble Space Telescope and James Webb Space Telescope. It shows Messier 64 captured at near- and mid-infrared wavelengths by Webb, while Hubble’s image shows the galaxy in ultraviolet, visible, and near-infrared light. These observations were taken to learn more about star formation in nearby galaxies.
