Known as the N44 superbubble complex, a storm of billowing clouds blown by the winds from massive stars, and set aglow by their light, is the focus of a striking image released today by Gemini Observatory.
The 200th paper is titled “The luminosity function of the fossil group RX J1552.2+2013” by Claudia L. Mendes de Oliveira et al.
Astronomers used GMOS on the Gemini North Telescope to determine the first luminosity function (LF) of the galaxies in fossil group RX J1552.2+2013 based on spectroscopy of the member galaxies.
Two upcoming papers based on optical and mid-infrared data from the Gemini North telescope focus on the dynamic core of the spiral galaxy NGC 1068.
The instrument clusters located at the Cassegrain foci of the Gemini telescopes are perhaps the most unique collections of astronomical instrumentation ever assembled on ground-based telescopes.
The unique nod-and-shuffle mode on the Gemini Multi-object Spectrograph (GMOS) provides a reduction of sky line residuals in the red part of the spectrum, making it a better tool to observe the faintest and highest redshift candidates.
The recent addition of a field lens in the Altair adaptive optics system has resulted in a significant improvement in near-infrared imaging capabilities at Gemini North.
Geologic activity on the surface of Saturn's moon Titan is belching puffs of methane gas into the atmosphere of the moon, creating clouds.
Astronomers using the Frederick C. Gillett Gemini Telescope on Mauna Kea have found the source of short flashes of gamma rays from outer space: a collision of two dead stars.
With system and science verification complete, the Gemini Bench-mounted High-Resolution Spectrograph (bHROS) is available for science programs in 2006A.
A series of coordinated observations, made under ideal conditions by the world’s largest collection of big telescopes, delivered surprising new insights into the ancestry and life cycles of comets.
Astronomers have glimpsed dusty debris around an essentially dead star where gravity and radiation should have long ago removed any sign of dust. The discovery might provide insights into our own solar system’s eventual demise several billion years from now.
The Gemini Observatory released a pair of images today that capture the dynamics of two very different interactions in space.
Astronomers using the 8-meter Gemini South telescope have revealed that the galaxy NGC 300 has a large, faint extended disk made of ancient stars, enlarging the known diameter of the galaxy by a factor of two or more.
Gemini Observatory has obtained a preliminary spectrum of 2003 UB313, the so-called "10th planet".
A relatively young star located about 300 light-years away is greatly improving our understanding of the formation of Earth-like planets.
Gemini Observatory is actively looking for sub-stellar mass companions using the existing Adaptive Optics (AO) system Altair on Gemini North, and building the specialized near-infrared coronagraph (NICI) with its own AO system for Gemini South.
The Gemini North telescope on Mauna Kea successfully captured the dramatic fireworks display produced by the collision of NASA's Deep Impact probe with Comet 9P/Tempel 1.
Imaging by Gemini North's Michelle mid-infrared imager/spectrograph has allowed an international team of researchers to isolate and characterize the dusty remains of the supernova remnant SN 2002hh.
