New WISE Image Captures Cosmic Star Birth

A new, large mosaic from NASA's Wide-Field Infrared Survey Explorer (WISE) showcases a vast stretch of cosmic clouds bubbling with new star birth. The region -- a 1,000-square-degree chunk of our Milky Way galaxy -- is home to numerous star-forming clouds, where massive stars have blown out bubbles in the gas and dust. "Massive stars sweep up and destroy their natal clouds, but they continuously spark new stars to form along the way," said WISE Mission Scientist Dave Leisawitz of NASA...

New Clues About Inner Workings Of Black Hole Jets

  Astronomers using NASA's Wide-field Infrared Survey Explorer (WISE) have captured rare data of a flaring black hole, revealing new details about these powerful objects and their blazing jets. Scientists study jets to learn more about the extreme environments around black holes. Much has been learned about the material feeding black holes, called accretion disks, and the jets themselves, through studies using X-rays, gamma rays and radio waves. But key measurements of the...

Background In November 2010, the scientific journal Icarus published a paper by astrophysicists John Matese and Daniel Whitmire, who proposed the existence of a binary companion to our sun, larger than Jupiter, in the long-hypothesized "Oort cloud" -- a faraway repository of small icy bodies at the edge of our solar system. The researchers use the name "Tyche" for the hypothetical planet. Their paper argues that evidence for the planet would have been recorded by the Wide-field Infrared...

NASA said on Tuesday that its near-Earth objects Wide-field Infrared Survey Explorer (NEOWOSE) mission has completed its survey of small bodies, asteroids and comets in our solar system. The mission's previous discoveries include 20 comets, over 33,000 asteroids in the main belt between Mars and Jupiter, and 134 near-Earth objects (NEOs). NEOs are asteroids and comets with orbits that come within 28 million miles of Earth's path around the sun. NASA said that NEOWISE is an enhancement of...

Astronomers have uncovered what appear to be 14 of the coldest stars known in our universe. These failed stars, called brown dwarfs, are so cold and faint that they'd be impossible to see with current visible-light telescopes. Spitzer's infrared vision was able to pick out their feeble glow, much as a firefighter uses infrared goggles to find hot spots buried underneath a dark forest floor. The brown dwarfs join only a handful of similar objects previously discovered. The new objects are...

All systems are behaving as expected on NASA's Wide-field Infrared Survey Explorer (WISE), which rocketed into the sky just before dawn on Dec. 14 from Vandenberg Air Force Base in California. The mission will undergo a one-month checkout before beginning the most detailed survey yet of the entire sky in infrared light. Hundreds of millions of objects will populate its vast catalog, including dark asteroids, the closest "failed" stars and tremendously energetic galaxies. Shortly after the...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
