NASA - National Aeronautics and Space AdministrationPasadena, CA – Gone are the days of being able to count the number of known planets on your fingers. Today, there are more than 800 confirmed exoplanets — planets that orbit stars beyond our sun — and more than 2,700 other candidates.

What are these exotic planets made of? Unfortunately, you cannot stack them in a jar like marbles and take a closer look. Instead, researchers are coming up with advanced techniques for probing the planets’ makeup.

This image shows the HR 8799 planets with starlight optically suppressed and data processing conducted to remove residual starlight. The star is at the center of the blackened circle in the image. The four spots indicated with the letters b through e are the planets. This is a composite image using 30 wavelengths of light and was obtained over a period of 1.25 hours on June 14th and 15th, 2012. (Image courtesy of Project 1640)

NASA’s reports Astronomers have found Green Galaxy churning out Stars

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers have spotted the “greenest” of galaxies, one that converts fuel into stars with almost 100-percent efficiency.

The findings come from NASA’s Wide-field Infrared Survey Explorer (WISE), NASA’s Hubble Space Telescope and the IRAM Plateau de Bure interferometer in the French Alps.

“This galaxy is remarkably efficient,” said Jim Geach of McGill University in Canada, lead author of a new study appearing in the Astrophysical Journal Letters. “It’s converting its gas supply into new stars at the maximum rate thought possible.”

NASA’s Wide-field Infrared Survey Explorer (WISE) captures dynamic image of Orion Nebula

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The tangle of clouds and stars that lie in Orion’s sword is showcased in a new, expansive view from NASA’s Wide-field Infrared Survey Explorer, or WISE.

Orion, the famous hunter, is visible in evening skies throughout the world from about December through April. The constellation appears tranquil and still to the naked eye, but lying in its sword, at what appears to be a slightly fuzzy star, is a turbulent cauldron of stellar birth.

The Orion nebula is featured in this sweeping image from NASA's Wide-field Infrared Survey Explorer, or WISE. The constellation of Orion is prominent in the evening sky throughout the world from about December through April of each year. The nebula (also catalogued as Messier 42) is located in the sword of Orion, hanging from his famous belt of three stars. The star cluster embedded in the nebula is visible to the unaided human eye as a single star, with some fuzziness apparent to the most keen-eyed observers. (Image Credit: NASA/JPL-Caltech/UCLA)

NASA’s Spitzer Space Telescope captures image of giant star Zeta Ophiuchi speeding through Space

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA -  Like a ship plowing through still waters, the giant star Zeta Ophiuchi is speeding through space, making waves in the dust ahead. NASA’s Spitzer Space Telescope has captured a dramatic, infrared portrait of these glowing waves, also known as a bow shock.

Astronomers theorize that this star was once sitting pretty next to a companion star even heftier than itself. But when that star exploded, Zeta Ophiuchi was kicked away and sent flying. Zeta Ophiuchi, which is 20 times more massive and 80,000 times brighter than our sun, is racing along at about 54,000 mph (24 kilometers per second).

 

The giant star Zeta Ophiuchi is having a "shocking" effect on the surrounding dust clouds in this infrared image from NASA's Spitzer Space Telescope. Stellar winds flowing out from this fast-moving star are making ripples in the dust as it approaches, creating a bow shock seen as glowing gossamer threads, which, for this star, are only seen in infrared light.

NASA’s Wide-field Infrared Survey Explorer (WISE) telescope searches for Gigantic Galaxy Clusters

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Our solar system, with its colorful collection of planets, asteroids and comets, is a fleck in the grander cosmos. Hundreds of billions of solar systems are thought to reside in our Milky Way galaxy, which is itself just a drop in a sea of galaxies.

The rarest and largest of galaxy groupings, called galaxy clusters, can be the hardest to find. That’s where NASA’s Wide-field Infrared Survey Explorer (WISE) can help. The mission’s all-sky infrared maps have revealed one distant galaxy cluster and are expected to uncover thousands more.

NASA’s Wide-field Infrared Survey Explorer (WISE) makes discovery about the Trojan asteroids in the same orbit as Jupiter around the Sun

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists using data from NASA’s Wide-field Infrared Survey Explorer, or WISE, have uncovered new clues in the ongoing mystery of the Jovian Trojans — asteroids that orbit the sun on the same path as Jupiter. Like racehorses, the asteroids travel in packs, with one group leading the way in front of the gas giant, and a second group trailing behind.

The observations are the first to get a detailed look at the Trojans’ colors: both the leading and trailing packs are made up of predominantly dark, reddish rocks with a matte, non-reflecting surface. What’s more, the data verify the previous suspicion that the leading pack of Trojans outnumbers the trailing bunch.

New results from NASA's Wide-field Infrared Explorer, or WISE, reveal that the Jovian Trojans -- asteroids that lap the sun in the same orbit as Jupiter -- are uniformly dark with a hint of burgundy color, and have matte surfaces that reflect little sunlight. (Image credit: NASA/JPL-Caltech)

NASA’s Wide-field Infrared Survey Explorer (WISE) images reveals hundreds of extreme Galaxies as well as millions of Supermassive Black Holes

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Wide-field Infrared Survey Explorer (WISE) mission has led to a bonanza of newfound supermassive black holes and extreme galaxies called hot DOGs, or dust-obscured galaxies.

Images from the telescope have revealed millions of dusty black hole candidates across the universe and about 1,000 even dustier objects thought to be among the brightest galaxies ever found. These powerful galaxies, which burn brightly with infrared light, are nicknamed hot DOGs.

With its all-sky infrared survey, NASA's Wide-field Infrared Survey Explorer, or WISE, has identified millions of quasar candidates. (Image credit: NASA/JPL-Caltech/UCLA)

NASA’s Wide-field Infrared Survey Explorer takes image of Flame Nebula in the Constellation Orion

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new image from NASA’s Wide-field Infrared Survey Explorer, or WISE, shows the candle-like Flame nebula lighting up a cavern of dust. The Flame nebula is part of the Orion complex, a turbulent star-forming area located near the constellation’s star-studded belt.

The image is being released along with a new batch of data from the mission. Last March, WISE released its all-sky catalog and atlas containing infrared images and data on more than a half billion objects, including everything from asteroids to stars and galaxies. Now, the mission is offering up additional data from its second scan of the sky.

The Flame Nebula sits on the eastern hip of Orion the Hunter, a constellation most easily visible in the northern hemisphere during winter evenings. (Image Credit: NASA/JPL-Caltech)

NASA’s Wide-field Infrared Survey Explorer (WISE) images shows Dust Disk orbiting Young Star has Mysteriously Disappeared

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Imagine if the rings of Saturn suddenly disappeared. Astronomers have witnessed the equivalent around a young sun-like star called TYC 8241 2652. Enormous amounts of dust known to circle the star are unexpectedly nowhere to be found.

“It’s like the classic magician’s trick: now you see it, now you don’t. Only in this case we’re talking about enough dust to fill an inner solar system and it really is gone!” said Carl Melis of the University of California, San Diego, who led the new study appearing in the July 5th issue of the journal Nature.

NASA’s Wide-field Infrared Survey Explorer (WISE) finds fewer Brown Dwarfs than Predicted Close to Home

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers are getting to know the neighbors better. Our sun resides within a spiral arm of our Milky Way galaxy about two-thirds of the way out from the center. It lives in a fairly calm, suburb-like area with an average number of stellar residents.

Recently, NASA’s Wide-field Infrared Survey Explorer, or WISE, has been turning up a new crowd of stars close to home: the coldest of the brown dwarf family of “failed” stars.

Now, just as scientists are “meeting and greeting” the new neighbors, WISE has a surprise in store: there are far fewer brown dwarfs around us than predicted.

This image shows our own back yard, astronomically speaking, from a vantage point about 30 light-years away from the sun. It highlights the population of tiny brown dwarfs recently discovered by NASA's Wide-field Infrared Survey Explorer, or WISE (red circles). The image simulates actual positions of stars.
