First finding as part of new research collaboration An international team of scientists that includes an astronomer from Princeton University has made the first direct observation of a planet-like object orbiting a star similar to the sun. The finding marks the first discovery made with the world's newest planet-hunting instrument on the Hawaii-based Subaru Telescope and is the first fruit of a novel research collaboration announced by the University in January. The object, known as GJ 758 B,...

NASA's Spitzer Space Telescope has contributed to the discovery of the youngest brown dwarf ever observed -- a finding that, if confirmed, may solve an astronomical mystery about how these cosmic misfits are formed. Brown dwarfs are misfits because they fall somewhere between planets and stars in terms of their temperature and mass. They are cooler and more lightweight than stars and more massive (and normally warmer) than planets. This has generated a debate among astronomers: Do brown...

NASA's Wide-field Infrared Survey Explorer, or Wise, is chilled out, sporting a sunshade and getting ready to roll. NASA's newest spacecraft is scheduled to roll to the pad on Friday, Nov. 20, its last stop before launching into space to survey the entire sky in infrared light. Wise is scheduled to launch no earlier than 9:09 a.m. EST on Dec. 9 from Vandenberg Air Force Base in California. It will circle Earth over the poles, scanning the entire sky one-and-a-half times in nine months. The...

Ninjas knew how to be stealthy: Be dark. Emit very little light. Move in the shadows between bright places. In modern warfare, though, ninjas would be sitting ducks. Their black clothes may be hard to see at night with the naked eye, but their warm bodies would be clearly visible to a soldier wearing infrared goggles. To hunt for the "ninjas" of the cosmos "” dim objects that lurk in the vast dark spaces between planets and stars "” scientists are building by far the most...

NASA's Wide-field Infrared Survey Explorer, or WISE, has been assembled and is undergoing final preparations for a planned Nov. 1 launch from Vandenberg Air Force Base, Calif. The mission will survey the entire sky at infrared wavelengths, creating a cosmic clearinghouse of hundreds of millions of objects -- everything from the most luminous galaxies, to the nearest stars, to dark and potentially hazardous asteroids. The survey will be the most detailed to date in infrared light, with a...

COLUMBIA, Md., June 2 /PRNewswire-USNewswire/ -- The Universities Space Research Association (USRA) is proud to announce that Dr. Eric Becklin has been selected as a fellow of the American Academy of Arts and Sciences (the Academy). One of the world's foremost infrared astronomers, Dr. Becklin has played a significant role in laying the basis for the modern science of astronomy with wide-ranging work that includes the discovery of the location of the nucleus of the Milky Way, one of the...

Planets near stars cooler than Earth's sun may lack the material to produce life, say scientists at Johns Hopkins University in Baltimore. The scientists used the infrared Spitzer Space Telescope to search for hydrogen cyanide around 61 young stars, hydrogen cyanide being a component of a compound in DNA found in every living thing on Earth, the Los Angeles Times reported Saturday. The researchers found hydrogen cyanide in 30 percent of the yellow, sun-like stars, but none around cooler,...

U.S.-led astronomers say new data hint that planets around stars cooler than the sun might have a differing mix of life-forming prebiotic chemicals. The astronomers used the Spitzer space telescope to look for a prebiotic chemical called hydrogen cyanide in the planet-forming material swirling around different types of stars. Hydrogen cyanide is a component of adenine that is a basic element of DNA, which is found in every living organism on Earth. The researchers said they detected hydrogen...

Cool Stars Have Different Mix of Life-Forming Chemicals Life on Earth is thought to have arisen from a hot soup of chemicals. Does this same soup exist on planets around other stars? A new study from NASA's Spitzer Space Telescope hints that planets around stars cooler than our sun might possess a different mix of potentially life-forming, or "prebiotic," chemicals. Astronomers used Spitzer to look for a prebiotic chemical, called hydrogen cyanide, in the planet-forming material swirling...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
