Look closely at this image from NASA’s Hubble Space Telescope and you’ll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily distinguished by the spikes that appear to extend outward from each star. These spikes, called diffraction spikes, are the […]

The Milky Way’s galactic bulge, the bulbous region that surrounds the galactic center, contains a dense collection of stars, planets, and other free-floating objects. This region has been studied for decades with numerous ground-based and space-based telescopes, including NASA’s Hubble and James Webb space telescopes.

A new paper from NASA’s Backyard Worlds: Planet 9 project announces that volunteers have essentially doubled the number of known brown dwarfs, with over 3,000 new discoveries made over the past 10 years since the project began. Brown dwarfs are balls of gas the size of Jupiter, less massive than stars.

A newly discovered object may be a key to unlocking the true nature of a mysterious class of sources that astronomers have found in the early universe in recent years. A “X-ray dot” found by NASA’s Chandra X-ray Observatory could explain what the hundreds or potentially thousands of these objects are. A paper describing the […]

A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this new NASA Hubble Space Telescope image. IC 486 lies right on the edge of the constellation Gemini (the Twins), around 380 million light-years from Earth. Classified as a barred spiral galaxy, […]
