Latest News About Stars and Galaxies
Stars are giant, luminous spheres of plasma. Galaxies consist of stars, stellar remnants, dust, gas, and dark matter, bound together by gravity. Learn more about stars and galaxies.
NASA's NuSTAR mission will peer through the dust and gas to see what what lies in the centers of other galaxies.
NASA's Kepler Mission, a space-based telescopic camera, has discovered planets orbiting stars beyond our Sun. Though an Earth-like planet in the "Goldilocks Zone" hasn't yet been positively identified, astronomers believe it's just a matter of time.
The new photo captures perhaps 1 percent of our galaxy's stars.
NASA's Spitzer Space Telescope is designed to study objects in infrared light.
The new image shows more than 200,000 galaxies that each contains billions of stars.
The globular cluster at the center of our galaxy contains stars twice as old as the sun.
New observations support the idea that galaxies expel gas and then suck it back in to create baby stars.
A new survey of distant galaxies provides new clues about how these cosmic objects evolved.
This cool space wallpaper shows a massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus Nebula, a turbulent star-birth region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way.
The Hercules cluster is unlike many other neighboring galaxy groups.
This stunning space wallpaper reveals the natural-color image of the galaxies was taken with NASA's Hubble Space Telescope and with the Canada-France-Hawaii Telescope in Hawaii.
Infrared observations of the Orion nebula show young stars as they mature into adulthood.
These outflows could shape the growth of black holes and dictate star formation in their host galaxies.
This mind-bending look at our day and night sky – including some auroras – was cut together by Randy Halverson (Dakotalapse.com). The score was composed by Bear McCreary (Battlestar Galactica, The Walking Dead, Eureka, etc.).
The galaxies are said to be in a smooth, curved line making them appear to be connected in a chain.
The extremely bright X-ray source in the Andromeda galaxy was first detected in late 2009.
The Carina nebula is home to several of the brightest and most massive known stars.
