A series of five new images from NASA’s Chandra X-ray Observatory show the beauty of space as seen in the X-ray wavelength. Data from Chandra has been combined with data from other telescopes operating in the visible light and infrared wavelengths to show some of the unique features of the high-energy universe.
The images show a range of objects from the heart of the Milky Way to supernova remnants, each one combining different sets of data to create a stunning view of an object that couldn’t be perceived in this way by human eyes.
The first image in the collection is titled Galactic Center. Here, the center of the Milky Way galaxy resembles a pink, orange, red, and purple cloud, dotted with several brilliant orbs of light. Surrounding the cloud is a dense field of purple, orange, red, and pale blue specks that entirely blanket the sky. In this image, orange, blue, and purple represent X-ray light from the Chandra X-ray Observatory.NASA/CXC/SAO, JPL-Caltech, MSFC, STScI, ESA/CSA, SDSS, ESO
The center of our galaxy, shown above, is a busy region full of objects like massive stars, incredibly dense neutron stars, superheated clouds of gas, and a supermassive black hole named Sagittarius A*. The clouds of bright color show the presence of energy in the X-ray wavelength.
The second image features Kepler’s Supernova Remnant, the remains of a white dwarf star that was destroyed by a thermonuclear explosion. The remnant resembles a knotted ball of crackling blue, red, and white energy, set against a black sky dotted with pale blue specks. Here, red streaks and patches of mottled turquoise represent debris from the destroyed star. A web of translucent electric blue veins that encircles and weaves through the knot represents the powerful blast wave captured by Chandra.NASA/CXC/SAO, JPL-Caltech, MSFC, STScI, ESA/CSA, SDSS, ESO
When a massive star reaches the end of its life and explodes as a supernova, the shockwave from the explosion can reach out far into space and interact with nearby dust and gas to form a supernova remnant. These shells appear around the site where the star exploded, and this image combines optical, infrared, and X-ray observations to show the different parts of the remnant like the debris and the blast wave.
In the third image, a bright, pale pink light encircled by translucent blue swirls rockets toward our upper left, leaving two, long, pink and purple tails behind it. This is ESO 137-001, a galaxy moving through space at 1.5 million miles per hour. Set against a black background packed with gleaming stars, the galaxy’s twin tails feature streams of pink floating inside superheated purple gas. Clusters of red dots, hydrogen atoms, appear to travel with the galaxy, alongside the flowing tails. In this image, X-ray light is represented by blue.NASA/CXC/SAO, JPL-Caltech, MSFC, STScI, ESA/CSA, SDSS, ESO
This galaxy zips through space at a tremendous speed of 1.5 million miles per hour, leaving a dramatic pair of tails in its wake. As the galaxy moves, it trails superheated gas which gives off X-rays that Chandra can observe, shown in blue. The patches of red are hydrogen, which was observed in the infrared. Visible light is represented in orange and cyan.
The fourth image in this release features a close-up of the spiral galaxy NGC 1365, and the supermassive black hole at its center. Here, the galaxy is shown at a dramatic angle, as if the bright pink core is gazing past our right shoulder. Swirls of pale, grey-blue material, resembling waves in a dark ocean, spiral toward the radiant pink core, which hangs at our upper left. Glowing pink circles, and flecks of red, dot the churning spiral galaxy.

Like our galaxy and most others, NGC 1365 also hosts a supermassive black hole at its center. This image shows the hot gas swirling around the black hole in purple, as it gradually falls in and the black hole devours it. The Chandra X-ray data is combined with infrared data from the James Webb Space Telescope.
The fifth and final image of this release features the Vela Pulsar, the aftermath of a collapsed and exploded star sending a jet of particles into space. The pulsar resembles a soft, pillowy, lavender bean in a pocket of blue gas. A faint stream of gas, the X-ray jet, appears to shoot from the pocket, heading into the distance at our upper right. Purple markings in the lavender bean shape strongly resemble narrow eyes and an open mouth, giving the pulsar a squinting happy face. In this image, X-ray light is shown in blues and purples.NASA/CXC/SAO, JPL-Caltech, MSFC, STScI, ESA/CSA, SDSS, ESO
Finally, another supernova remnant is shown here. Within the remnant is a pulsar, a type of neutron star that has a strong magnetic field and which gives off regular pulses of energy in high wavelengths like X-ray and gamma-ray. The purple glow is X-ray energy captured by Chandra, while blue light is from another X-ray telescope called IXPE. It is set over a background of stars captured in the visible light wavelength.
Creepy cosmic eyes stare out from space in Webb and Hubble image
These sinister eyes gazing out from the depths of space star in a new Halloween-themed image, using data from both the Hubble Space Telescope and the James Webb Space Telescope. It shows a pair of galaxies, IC 2163 on the left and NGC 2207 on the right, which are creeping closer together and interacting to form a creepy-looking face.
The two galaxies aren't colliding directly into one another, as one is passing in front of the other, but they have passed close enough to light scrape by each other and leave indications. If you look closely at the galaxy on the left, you can see how its spiral arms have been pulled out into an elongated shape, likely because of its close pass to the gravity of the other nearby galaxy. The lines of bright red around the "eyes" are created by shock fronts, with material from each galaxy slamming together.
A SpaceX Crew Dragon spacecraft has set a new record
SpaceX’s Crew-8 members are finally on their way home after spending nearly eight months at the International Space Station (ISS).
The crew members were supposed to depart the ISS several weeks ago, but poor weather conditions at the splashdown site off the coast of Florida prompted mission planners to delay the homecoming. Prior to that, delays to departure were caused by measures to deal with Boeing’s troubled Starliner spacecraft, which was docked at the station over the summer.
