Astronomers have made the most detailed study yet of an extremely massive young galaxy cluster using three of NASA's Great Observatories. This rare galaxy cluster, located 10 billion light-years from Earth, is almost as massive as 500 trillion suns.
The discovery of likely Eta Carinae 'twins' in other galaxies will help scientists better understand this brief phase in the life of a massive star with images such as this from NASA's Hubble Space Telescope.
Galaxy NGC 1068 can be seen in close-up in this view from NASA's Hubble Space Telescope. NuSTAR data revealed that the torus of gas and dust surrounding the black hole, also referred to as a doughnut, is more clumpy than previously thought.
Galaxy NGC 1068 is shown in visible light and X-rays in this composite image. High-energy X-rays (magenta) captured by NASA's NuSTAR, are overlaid on visible-light images from both NASA's Hubble Space Telescope and the Sloan Digital Sky Survey.
This image shows an artist's impression of the 10 hot Jupiter exoplanets studied using the Hubble and Spitzer space telescopes. (Top L, Bottom R -- WASP-12b, WASP-6b, WASP-31b, WASP-39b, HD 189733b, HAT-P-12b, WASP-17b, WASP-19b, HAT-P-1b, HD 209458b)
Cool Star Marked by Long-Lived Storm (Artist's Concept)
This illustration shows a cool star, called W1906+40, marked by a raging storm near one of its poles. The storm is thought to be similar to the Great Red Spot on Jupiter. Scientists discovered it using NASA's Kepler and Spitzer space telescopes.
The galaxy cluster called MOO J1142+1527 can be seen here as it existed when light left it 8.5 billion years ago. The red galaxies at the center of the image from NASA's Spitzer make up the heart of the galaxy cluster.
Shifting Coronas Around Black Holes (Artist Concept)
In 2014, NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, and Swift space telescopes witnessed an X-flare from the supermassive black hole in a distant galaxy called Markarian 335. Artist Concept.
Scores of baby stars shrouded by dust are revealed in this infrared image of the star-forming region NGC 2174, as seen by NASA's Spitzer Space Telescope. Found in the constellation Orion, NGC 2174 is located around 6,400 light-years away.
This sky map shows the location of the star HD 219134 (circle), host to the nearest confirmed rocky planet found to date outside of our solar system. The star lies just off the 'W' shape of the constellation Cassiopeia.
Little Black Spot on the Star Today (Artist's Concept)
This artist's conception shows the silhouette of a rocky planet, dubbed HD 219134b, as it passes in front of its star. At 21 light-years away, the planet is the closest outside of our solar system that can be seen crossing, or transiting, its star.
Of the 1,030 confirmed planets from Kepler, a dozen are less than twice the size of Earth and reside in the habitable zone of their host stars. In this diagram, the sizes of the exoplanets are represented by the size of each sphere.
