Scientists have discovered a new class of objects using NASA's Chandra X-ray Observatory that are behaving unlike any seen before. These mysterious objects may help solve not one, but two long-standing questions in astrophysics. More: https://t.co/MaQaxW85dy https://t.co/nQoQoQLD
A composite image of a spiral galaxy, M101; one of six identified galaxies housing a new class of mysterious objects that give off unusually low-energy X-rays. In this image, M101 faces us directly. It has multiple arms in shades of purple, spiraling clockwise around a golden yellow core. Scattered along and between the arms are scores of tiny specks in white and purple. Most of those specks are pairs of stars, but seven of them are a mystery. To casual observers, the unusual objects are visually indistinguishable from the other specks of light in the galaxy. The curious objects give off X-rays of such low energy, they in fact produce large amounts of ultraviolet radiation, as UV radiation borders X-rays on the electromagnetic spectrum. Searching images of galaxies with low-energy X-rays in the Chandra Observatory archive, scientists have found a total of 84 such objects spread across M101 and five other galaxies. They have dubbed these mysterious objects "hypersoft X-ray sources."

Starburst galaxies are galaxies that are undergoing incredibly high rates of star formation. NGC 1569 is one such galaxy — forming stars roughly 100 times faster than our own Milky Way Galaxy for the past 100 million years or so. https://t.co/Hb9nyecYaf
NGC 1569, a compact dwarf irregular galaxy undergoing a violent, compact burst of star formation. Chandra and XMM-Newton observations (blue and purple) reveal massive bubbles of million-degree gas inflated by stellar winds, set against a backdrop of optical light (magenta, orange and white) imaged by Adam Block. Dwarf starburst galaxies can serve as local laboratories for studying the conditions of the early universe, where small, primitive galaxies formed stars at frantic rates. Overall, NGC 1569 resembles a tangle of glowing red yarn surrounding a white sparkler.

Take in this new image of the barred spiral galaxy NGC 1672 from Chandra, @NASAHubble, and @NASAWebb. Studying barred spirals in action can help reveal how gas in our own Milky Way, which is also a barred spiral, feeds its central black hole and forms new stars.🌀 https://t.co/ONV
This is a multiwavelength image of galaxy NGC 1672. At its center are two thick, spiraling, dark purple arms that bridge a brilliant white and neon pink core. Those bridging arms create a bar, which channels gas to the core, making NGC 1672 a barred spiral galaxy, like our own Milky Way. Longer, wispier arms also spiral out from the core, dotted with gleaming white and pink stars.

@chandraxray The details from Webb in red really pop. Wonder what we’d see if we threw even more telescopes at it. 312 views · 1 likes · 0 reposts · 0 replies Open on X →

Like a collage made of layered sheets of colored cellophane, a vibrant new image layers observations of the Tarantula Nebula from NASA's Chandra (blue), Hubble (green), and Webb (red). More: https://t.co/7q1F5LXwgD https://t.co/gMxMGoLqk4

Three images of the Tarantula Nebula, each representing a different wavelength of light, presented in a different color. When layered atop one another, like sheets of colored cellophane, they combine to produce a vibrant and informative singular image. The base layer features a blanket of wispy blue clouds against a black backdrop. These clouds represent hot gas observed by Chandra. The second layer cuts diagonally across the cloudy blue square, tilted from our upper left down toward our lower right. This red layer represents infrared data collected by Webb. The third layer is a diamond-shaped image, with its points touching the edges of the big blue base layer. This green layer represents data captured by NASA's Hubble Space Telescope. In the center of the combined image, the three translucent layers overlap, resulting in an image of intermingled blue, red, and green clouds that blend to include lively shades of fiery orange, golden yellow, and deep purple.
