... September 21, 1998 . NGC 281: Cluster, Clouds, and Globules . ... Explanation: NGC 281 is a busy workshop of star formation. Prominent features include a small open cluster of stars, a diffuse red-glowing emission nebula , large lanes of obscuring gas and dust , and dense knots of dust and gas in which stars may still be forming. The open cluster of stars IC 1590 visible on the upper right has formed only in the last few million years. ... About APOD > . ...

home publications > mercury . ... Big Clusters, Tiny Galaxies . ... Astronomers struggle to understand why giant star clusters form in the tiniest of galaxies . ... These clusters are probably young versions of globular clusters, but they are commonly called super star clusters. Seven dwarf galaxies within 16 million light-years have formed super star clusters, with one of these galaxies, NGC 1569, possessing two young clusters. ... Super star clusters have a lot to tell us about star formation. ...

... Resolved Stellar Populations Globular Clusters . Galaxies are made of stars, gas and the illusive dark matter. ... Star clusters are the simplest form of the stellar population. ... Old globular clusters are easily observed at great distances and can be used as probes of the early stages of star formation history in galaxies where individual stars cannot be resolved. My research interests are centered on the studies of resolved stellar populations and (old) star clusters in nearby galaxies. ...

Photon Scattering: Basic Principle of Photon Scattering . Audio Narration is available . No Scattering: Photon Source and Detector . ... For optical photons, scattering goes as wavelength to the -4 power. In the case of blue photons compared to red photons, this means that blue photons are about 10 times more likely to get scattered than red photons. ... Watch the blue photons scatter away from the detector . ... Interstellar dust make stars appear redder than they really are . ...

... Circumstellar Disks in Young Nebulous Clusters . ... HST . ... To take advantage of the enhanced visibility of circumstellar matter externally illuminated in a nebular environment, and to determine if the Orion "proplyds" are unique, we observed four other young nebulous clusters with HST/WFPC2 during Cycle 5. Eight fields were observed in H-alpha and I-band continuum in the nearby H II regions NGC 2024, NGC 2264, and S155. Two fields were observed in V-band in the reflection nebula NGC 7023. ...
