Since 1999, a lot of things have come and gone -- the Y2K bug, a slew of boy bands and a new Star Wars trilogy. But NASA's Chandra X-ray Observatory, which unveiled its first images just a few months shy of the new millennium, continues to make headlines seven years later. Maybe it's because Chandra's subjects are timeless -- black holes, distant galaxies, and stars that don't reside in Hollywood. And they're long-lasting -- with stellar lives that span billions of years. Or maybe it's...

NASA's Hubble Space Telescope has uncovered what astronomers are reporting as the dimmest stars ever seen in any globular star cluster. Globular clusters are spherical concentrations of hundreds of thousands of stars. These clusters formed early in the 13.7-billion-year-old universe. The cluster NGC 6397 is one of the closest globular star clusters to Earth. Seeing the whole range of stars in this area will yield insights into the age, origin, and evolution of the cluster. Although...

This is a unique NASA Hubble Space Telescope view of the disk galaxy NGC 5866 tilted nearly edge-on to our line-of-sight. Hubble's sharp vision reveals a crisp dust lane dividing the galaxy into two halves. The image highlights the galaxy's structure: a subtle, reddish bulge surrounding a bright nucleus, a blue disk of stars running parallel to the dust lane, and a transparent outer halo. Some faint, wispy trails of dust can be seen meandering away from the disk of the galaxy out into the...

NASA - Looking like a child's pinwheel ready to be set a spinning by a gentle breeze, this dramatic spiral galaxy is one of the latest viewed by NASA's Hubble Space Telescope. Stunning details of the face-on spiral galaxy, cataloged as NGC 1309, are captured in this color image. Recent observations of the galaxy taken in visible and infrared light come together in a colorful depiction of many of the galaxy's features. Bright blue areas of star formation pepper the spiral arms, while ruddy...

RIT -- How does matter spiral its way to the center of a galaxy and into the mouth of a supermassive black hole? A new study provides the best glimpse yet at the death spiral of material as it descends into the core of a galaxy hosting a large black hole. The study predicts that, barring obstructions, the galactic debris will take about 200,000 years to make a one-way trip through the inner regions of the galaxy and into oblivion. An international team of scientists led by Kambiz Fathi at...

NASA -- Scientists using NASA's Chandra X-ray Observatory have discovered evidence of energetic plumes - particles that extend 300,000 light years into a massive cluster of galaxies. The plumes are due to explosive venting from the vicinity of a supermassive black hole, and they provide dramatic new evidence of the influence a black hole can have over intergalactic distances. "In relative terms, it is as if a heat source the size of a fingernail affects the behavior of a region the size of...

Cambridge, MA -- Just in time for Thanksgiving, NASA's Spitzer Space Telescope has harvested a bounty of young stars. A new infrared image of the reflection nebula NGC 1333, located about 1,000 light-years from Earth in the constellation Perseus, reveals dozens of stars like the Sun but much younger. "These newborns are less than a million years old - babies by astronomical standards," said Rob Gutermuth of the Harvard-Smithsonian Center for Astrophysics (CfA). "Our Sun may have formed in a...

NASA -- This is a Hubble Space Telescope view of one of the most dynamic and intricately detailed star-forming regions in space, located 210,000 light-years away in the Small Magellanic Cloud (SMC), a satellite galaxy of our Milky Way. At the center of the region is a brilliant star cluster called NGC 346. A dramatic structure of arched, ragged filaments with a distinct ridge surrounds the cluster. A torrent of radiation from the cluster's hot stars eats into denser areas creating a fantasy...

New VLT Images Reveal the Surroundings of a Super-massive Black Hole ESO -- Near-infrared images of the active galaxy NGC 1097, obtained with the NACO adaptive optics instrument on ESO's Very Large Telescope, disclose with unprecedented detail a complex central network of filamentary structure spiralling down to the centre of the galaxy. These observations provide astronomers with new insights on how super-massive black holes lurking inside galaxies get fed. "This is possibly the first time...

ESO's VLT Captures Image of Spiral Galaxy NGC 1350 Eighty-five million years ago on small planet Earth, dinosaurs ruled, ignorant of their soon-to-come demise in the great Jurassic extinction, while mammals were still small and shy creatures. The southern Andes of Bolivia, Chile, and Argentina were not yet formed and South America was still an island continent. Eighty-five million years ago, our Sun and its solar system was 60,000 light years away from where it now stands [1]. Eighty-five...

The NGC 5866, located in the Draco constellation, is named after the galaxy with the highest magnitude however some catalogs list NGC 5907 as the brightest member. The M51 Group and the M101 Group are NGC 5866 closest neighbor. The distances between these groups are similar which suggest the three groups are part of a single large, loose, elongated group. However, most identification methods consider them separate.

The M81 Group, containing the well known galaxies Messier 81 and Messier 82, is a group of galaxies within the constellation Ursa Major. Along with Messier 81 and 82 are several other galaxies with apparent brightness. The center, located at an approximate distance of 3.6 Mpc, is one of the nearest groups to the Local Group. The total estimated mass of the group is (1.03 ± 0.17) × 1012M☉. The Virgo Supercluster contains the M81 Group, the Local Group, and some other nearby...

The M51 Group, located in Canes Venatici, is named after the brightest galaxy in the group, the Whirlpool Galaxy (M51A). The few other notable members include the companion galaxy to the Whirlpool Galaxy (M51B) and the Sunflower Galaxy (M63).

The Coma Cluster (Abell 1656), along with the Leo Cluster, is one of two major clusters compromising the Coma Supercluster. It contains over 1000 identified galaxies. Most of the galaxies in the center of the Coma Cluster are elliptical galaxies including both dwarf and giant. However the center is dominated by NGC 4874 and NGC 4889, two giant elliptical galaxies. The brightest galaxies are visible, a few degrees north of the galactic pole, with an amateur telescope larger than 20 cm. The...

Stephan's Quintet in the constellation Pegasus is a visual grouping of five galaxies which four form the first compact galaxy group ever discovered. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory and is the most studied of all the compact galaxy groups. NGC 7320, which has extensive H II regions, is the brightest member of the visual grouping and is where active star formation is occurring. Hickson Compact Group 92, which contains four of the five...

Word of the Day
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
