This artist's conception portrays a free-floating brown dwarf, or failed star. A new study shows that several of these objects are warmer than previously thought with temperatures about 250-350 degrees Fahrenheit. Credit: NASA/JPL-Caltech

The locations of brown dwarfs discovered by NASA's Wide-field Infrared Survey Explorer, or WISE, and mapped by NASA's Spitzer Space Telescope, are shown here in this diagram. The view is from a vantage point about 100 light-years away from the sun, looking back towards the constellation Orion. At this distance our sun is barely visible as a speck of light. The vastly fainter brown dwarfs would not even be visible in this view. The red lines all link back to the location of the sun. Credit: NASA/JPL-Caltech

This composite image traces Milky Way-like galaxies over most of cosmic history, revealing how they evolve over time. It shows examples of galaxies similar to the Milky Way at various stages of construction over 11 billion years. The galaxies are arranged according to time. Those on the left reside nearby; those at far right existed when the cosmos was about 2 billion years old. Credit: Image by NASA, ESA, P. van Dokkum [Yale University], S. Patel [Leiden University], and the 3-D HST Team

Image of the ROXs 42B system obtained with the Keck telescope. The star is located in the center of the masked region. ROXs 42Bb orbits at about 150 astronomical units (AU - 1 AU=the distance from Earth to the Sun.) The other object ("c") is a likely unrelated background star.

Gemini Planet Imager's first light image of the light scattered by a disk of dust orbiting the young star HR4796A. This narrow ring is thought to be dust from asteroids or comets left behind by planet formation; some scientists have theorized that the sharp edge of the ring is defined by an unseen planet. The left image shows normal light, including both the dust ring and the residual light from the central star scattered by turbulence in the Earth's atmosphere. The right image shows only polarized light. Leftover starlight is unpolarized and hence removed from this image. The light from the back edge of the disk is strongly polarized as it scatters towards us. Credit: Processing by Marshall Perrin, Space Telescope Science Institute

Gemini Planet Imager's first light image of Beta Pictoris b, a planet orbiting the star Beta Pictoris. The star, Beta Pictoris, is blocked in this image by a mask so its light doesn't interfere with the light of the planet. In addition to the image, GPI obtains a spectrum from every pixel element in the field of view to allow scientists to study the planet in great detail. Beta Pictoris b, a 10 million year old planet several times larger than Jupiter. Image courtesy of Gemini Observatory, processing by Christian Marois/NRC Canada
