[WATCH VIDEO: Space Warps Gravitational Lensing Animation] Lee Rannals for redOrbit.com — Your Universe Online Volunteers are being summoned to help astronomers find "space warps," leading to the discovery of faraway objects. Space warps, more commonly known as "gravitational lenses," allow objects in space to act as a giant lens to other objects even farther away. Studies have found that the human brain is much better at identifying lenses than current computer algorithms, so...

Previously Unknown Giant Radio Galaxy Discovered By LOFAR

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have discovered a previously unknown gigantic radio galaxy using the powerful International LOFAR Telescope (ILT). The team was browsing the first set of photos taken during LOFAR's first all-sky imaging survey known as the Multi-frequency Snapshot Sky Survey (MSSS). While browsing the first set of MSSS images, ASTRON astronomer Dr. George Heald found a new source of radio emission the size of the full moon...

A newly developed image analysis technique has significantly improved the sensitivity limits reached by the IBIS imager on board INTEGRAL, resulting in the deepest survey ever compiled of the entire sky in the energy range between 17 and 60 keV. Pushing the instrument towards its very limits, the novel method discloses a vast number of previously undetected faint sources, galactic and extragalactic alike. For more than seven years, the INTEGRAL observatory has been surveying the entire X-ray...

Astronomers scanning the skies as part of ESO's VISTA Magellanic Cloud survey have now obtained a spectacular picture of the Tarantula Nebula in our neighboring galaxy, the Large Magellanic Cloud. This panoramic near-infrared view captures the nebula itself in great detail as well as the rich surrounding area of sky. The image was obtained at the start of a very ambitious survey of our neighboring galaxies, the Magellanic Clouds, and their environment. The leader of the survey team,...

This week, Astronomy & Astrophysics is publishing a special feature devoted to the new results obtained with the infrared satellite AKARI, a JAXA project with the participation of ESA. It includes 17 articles dealing with various subjects. Some papers are based on the AKARI all-sky survey, which has just been released. Others are dedicated to pointed observations of many astronomical targets from solar system bodies to distant galaxies. Astronomy & Astrophysics is publishing a special...

Two new infrared catalogues, containing more than 1.3 million celestial sources, are made public today. The AKARI All-Sky Catalogues, based on the first all-sky infrared survey in more than a quarter of a century, will provide important new data for a wide range of studies that cover topics ranging from the properties of nearby stars, to the formation of planetary systems, and the star formation history of the distant Universe. All-sky surveys are an essential tool for astronomers. The large...

A new telescope "” VISTA (the Visible and Infrared Survey Telescope for Astronomy) "” has just started work at ESO's Paranal Observatory and has made its first release of pictures. VISTA is a survey telescope working at infrared wavelengths and is the world's largest telescope dedicated to mapping the sky. Its large mirror, wide field of view and very sensitive detectors will reveal a completely new view of the southern sky. Spectacular new images of the Flame Nebula, the center...

The U.S. space agency says its wide-field infrared survey explorer instrument named WISE is ready to be joined with its satellite for launch later this year. The Space Dynamics Laboratory in North Logan, Utah, the builder of the instrument, said it has shipped WISE to the Ball Aerospace & Technologies Corp. in Boulder, Colo., where it will be integrated onto the satellite. The SDL-built WISE instrument will collect millions of images, from which hundreds of millions of astronomical...

XMM-Newton has discovered an exploding star in the Milky Way. Usually that would be important in itself, but this time there is a special twist. Calculations show that the explosion must have been clearly visible to the unaided eye but was missed by the legions of star watchers around the planet. On October 9, 2007, ESA's orbiting X-ray observatory XMM-Newton was turning from one target to another. As it did so, it passed across a bright source of X-rays that no one was expecting. The source...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
