NASA - National Aeronautics and Space AdministrationPasadena, CA – For a planet, this would be like a day at the spa. After years of growing old, a massive planet could, in theory, brighten up with a radiant, youthful glow. Rejuvenated planets, as they are nicknamed, are only hypothetical.

But new research from NASA’s Spitzer Space Telescope has identified one such candidate, seemingly looking billions of years younger than its actual age.

“When planets are young, they still glow with infrared light from their formation,” said Michael Jura of UCLA, coauthor of a new paper on the results in the June 10th issue of the Astrophysical Journal Letters. “But as they get older and cooler, you can’t see them anymore. Rejuvenated planets would be visible again.”

This artist's concept shows a hypothetical "rejuvenated" planet -- a gas giant that has reclaimed its youthful infrared glow. NASA's Spitzer Space Telescope found tentative evidence for one such planet around a dead star, or white dwarf, called PG 0010+280 (depicted as white dot in illustration). (NASA/JPL-Caltech)

NASA - National Aeronautics and Space AdministrationPasadena, CA – Imagine trying to create a map of your house while confined to only the living room. You might peek through the doors into other rooms or look for light spilling in through the windows. But, in the end, the walls and lack of visibility would largely prevent you from seeing the big picture.

The job of mapping our own Milky Way galaxy from planet Earth, situated about two-thirds of the way out from the galaxy’s center, is similarly difficult. Clouds of dust permeate the Milky Way, blocking our view of the galaxy’s stars.

NASA’s Wide-field Infrared Survey Explorer (WISE) data used to find Bright Distant Galaxy

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A remote galaxy shining with the light of more than 300 trillion suns has been discovered using data from NASA’s Wide-field Infrared Survey Explorer (WISE).

The galaxy is the most luminous galaxy found to date and belongs to a new class of objects recently discovered by WISE — extremely luminous infrared galaxies, or ELIRGs.

“We are looking at a very intense phase of galaxy evolution,” said Chao-Wei Tsai of NASA’s Jet Propulsion Laboratory in Pasadena, California, lead author of a new report appearing in the May 22nd issue of The Astrophysical Journal. “This dazzling light may be from the main growth spurt of the galaxy’s black hole.”

NASA to increase search for Life on other Planets with NExSS Project

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA is bringing together experts spanning a variety of scientific fields for an unprecedented initiative dedicated to the search for life on planets outside our solar system.

The Nexus for Exoplanet System Science, or “NExSS”, hopes to better understand the various components of an exoplanet, as well as how the planet’s stars and neighbor planets interact to support life.

The search for life beyond our solar system requires unprecedented cooperation across scientific disciplines. NASA's NExSS collaboration includes those who study Earth as a life-bearing planet (lower right), those researching the diversity of solar system planets (left), and those on the new frontier, discovering worlds orbiting other stars in the galaxy (upper right).

NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) images now available Online to the Public

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Millions of images of celestial objects, including asteroids, observed by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft now are available online to the public. The data was collected following the restart of the asteroid-seeking spacecraft in December 2013 after a lengthy hibernation.

The collection of millions of infrared images and billions of infrared measurements of asteroids, stars, galaxies and quasars spans data obtained between December 13th, 2013, and December 13th, 2014.

The NEOWISE spacecraft viewed comet C/2014 Q2 (Lovejoy) on January 30, 2015, at a solar distance of 120 million miles (193 million kilometers). (NASA/JPL-Caltech)

NASA’s Wide-field Infrared Survey Explorer (WISE) discovers stars at the edge of the Milky Way Galaxy

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers using data from NASA’s Wide-field Infrared Survey Explorer, or WISE, have found a cluster of stars forming at the very edge of our Milky Way galaxy.

“A stellar nursery in what seems to be the middle of nowhere is quite surprising,” said Peter Eisenhardt, the project scientist for the WISE mission at NASA’s Jet Propulsion Laboratory in Pasadena, California. “But surprises turn up when you look everywhere, as the WISE survey did.”

The newfound young star clusters lie thousands of light-years below the plane of our Milky Way galaxy, a flat spiral disk seen in this artist's conception. If alien lifeforms were to develop on planets orbiting these stars, they would have views of a portion, or all, of the galactic disk. (NASA/JPL-Caltech)

NASA’s Wide-field Infrared Survey Explorer (WISE) data analyzed by Volunteer Disk Detectives finds possible Planetary Habitats

 

Written by Francis Reddy
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – A NASA-sponsored website designed to crowdsource analysis of data from the agency’s Wide-field Infrared Survey Explorer (WISE) mission has reached an impressive milestone.

In less than a year, citizen scientists using DiskDetective.org have logged 1 million classifications of potential debris disks and disks surrounding young stellar objects (YSO). This data will help provide a crucial set of targets for future planet-hunting missions.

The marked asymmetry of the debris disk around the star HD 181327 suggests it may have formed as a result of the collision of two small bodies. The Disk Detective project aims to discover many other stellar disks using volunteer classifications of data from NASA's WISE mission. (NASA/ESA/Univ. of Arizona/HST/GO 12228 Team)

NASA’s Spitzer Space Telescope captures image of Horsehead Nebula

 

Written by Whitney Clavin

NASA - National Aeronautics and Space AdministrationPasadena, CA – Sometimes a horse of a different color hardly seems to be a horse at all, as, for example, in this newly released image from NASA’s Spitzer Space Telescope. The famous Horsehead nebula makes a ghostly appearance on the far right side of the image, but is almost unrecognizable in this infrared view.

In visible-light images, the nebula has a distinctively dark and dusty horse-shaped silhouette, but when viewed in infrared light, dust becomes transparent and the nebula appears as a wispy arc.

The famous Horsehead nebula of visible-light images (inset) looks quite different when viewed in infrared light, as seen in this newly released image from NASA's Spitzer Space Telescope. (NASA/JPL-Caltech/ESO)

NASA’s Wide-field Infrared Survey Explorer (WISE) Black Hole Survey has astronomers reexamining “Doughnut” Theory

 

Written by J.D. Harrington
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A survey of more than 170,000 supermassive black holes, using NASA’s Wide-field Infrared Survey Explorer (WISE), has astronomers reexamining a decades-old theory about the varying appearances of these interstellar objects.

The unified theory of active, supermassive black holes, first developed in the late 1970s, was created to explain why black holes, though similar in nature, can look completely different. Some appear to be shrouded in dust, while others are exposed and easy to see.

Active, supermassive black holes at the hearts of galaxies tend to fall into two categories: those that are hidden by dust, and those that are exposed. (NASA/JPL-Caltech)
