NGC 1448, a galaxy with an active galactic nucleus hidden by gas and dust, is seen in this image combining data from the Carnegie-Irvine Galaxy Survey in the optical range and NASA's NuSTAR in the X-ray range.
This artist's concept shows a pulsar, which is like a lighthouse, as its light appears in regular pulses as it rotates. Pulsars are dense remnants of exploded stars, and are part of a class of objects called neutron stars.
This artist's concept depicts 'heartbeat stars,' which have been detected by NASA's Kepler Space Telescope. Two heartbeat stars are seen swerving close to one another in their closest approach along their highly elongated orbits around one another.
This illustration based on computer modeling and data from NASA's Kepler Space Telescope, represents how hot Jupiters of different temperatures and different cloud compositions might appear while flying over the dayside of these planets on a spaceship.
This image of galaxy cluster Abell 2744, also called Pandora's Cluster, was taken by NASA's Spitzer Space Telescope. The gravity of this galaxy cluster is strong enough that it acts as a lens to magnify images of more distant background galaxies.
Infrared Echoes of a Black Hole Eating a Star (Illustration)
This illustration shows a glowing stream of material from a star as it is being devoured by a supermassive black hole in a tidal disruption flare. Astronomers gained new insights into tidal disruption flares thanks to data from NASA's WISE.
These nebulae seen by NASA's Spitzer Space Telescope, display two regions of star formation that are hidden behind a haze of dust when viewed in visible light, known officially y their catalog numbers, IRAS 19340+2016 and IRAS19343+2026.
The blue dots in this field of galaxies, known as the COSMOS field, show galaxies that contain supermassive black holes emitting high-energy X-rays, as detected by NASA's Nuclear Spectroscopic Array, or NuSTAR.
This artist's impression depicts the accretion disc surrounding a black hole, in which the inner region of the disc precesses. 'Precession' means that the orbit of material surrounding the black hole changes orientation around the central object.
Studies based on observations from NASA's Hubble Space Telescope show that hot Jupiters, exoplanets around the same size as Jupiter that orbit very closely to their stars, often have cloud or haze layers in their atmospheres.
New stars are the lifeblood of our galaxy, and there is enough material revealed by ESA's Herschel of the constellation Vulpecula (little fox) OB1. The giant stars at the heart of Vulpecula OB1 are some of the biggest in the galaxy.
