December 2, 2013 - Astronomy.com
For decades, astronomers have puzzled over an odd source of X-ray light
in an arm of the galaxy M101, just off the handle of the Big Dipper. The
object, like other so-called ultraluminous X-ray sources, is a system
made of a star and a black hole that orbit each other. But its
brightness and estimated mass haven’t seemed to add up.
...
To measure the mass of this system, known as ULX-1, Liu and colleagues
first looked at the system through the Gemini telescope. Then they
conducted a spectroscopic analysis of the images, which involved
analyzing the color of the light to figure out which elements the star
in the system contained. They found that there wasn’t much hydrogen in
the star. That helped them determine it’s a type known as a Wolf-Rayet.
Such stars are rare, large, and hot. And they’re shrinking fast due to
their strong stellar winds.

Stellar-Mass Black Hole Caught Consuming Matter In A Surprisingly Calm Manner
http://www.redorbit.com/news/space/1113015781/black-hole-gemini-unexpected-discovery-in-messier-101-112913/
November 27, 2013 - redOrbit.com
Our understanding of how some black holes
consume matter might be changed by new observations of a black hole
powering an energetic X-ray source in a galaxy some 22 million light
years away. The findings, published in a recent issue of Nature,
indicate that this particular black hole, thought to be the engine
behind the X-ray source’s high-energy light output, is unexpectedly
lightweight. Additionally, in spite of the generous amount of dust and
gas being fed to it by a massive stellar companion, it swallows this
material in a surprisingly orderly fashion.

They were surprised, therefore, when the Gemini Observatory data revealed that M101 ULX-1′s black hole is on the small side. Astrophysicists are unable to explain why this is so.

The researchers who published the astronomy-upending paper used the Gemini telescope to study the light coming from this system, named M101 ULX-1. It’s 20 million light-years away in the spiral galaxy M101 (often called the Pinwheel galaxy). Made up of the black hole and a companion star, the system turned out to be relatively free of hydrogen, suggesting the star was of a particular variety known as a Wolf-Rayet. Knowing what kind of star the companion was, the researchers could determine from its light that it was about 19 times as massive as the sun (typical for these rare stars).

The Colliding Spiral Galaxies of Arp 271
http://apod.nasa.gov/apod/ap130825.html
August 25, 2013 - Astronomy Picture of the Day
Spiral galaxies
NGC 5426 and NGC 5427 are passing dangerously close to each other,
but each is likely to survive this collision.
Typically when
galaxies collide,
a large galaxy eats a much smaller galaxy.
In this case, however, the two galaxies are quite similar, each being a
sprawling spiral
with expansive arms and a compact core.
As the galaxies advance over the next tens of millions of years, their
component stars are unlikely to collide, although new stars will form in
the bunching of gas caused by
gravitational tides.
Close inspection of the
above image taken by the 8-meter
Gemini-South Telescope in
Chile shows a
bridge
of material momentarily connecting the two giants.

03 de Julio, 2013 - El Observatodo
Los astrónomos recientemente pusieron sus manos en el nuevo y revolucionario sistema de óptica adaptativa del Observatorio Gemini, llamado GeMS, “y los datos son realmente espectaculares!” dice Robert Blum, Sub Director del Observatorio de Astronomía Optica Nacional de EEUU. "Lo que hemos visto hasta ahora es señal de una increíble capacidad que va por encima de todo ya sea en el espacio o en la tierra – y así será por un buen tiempo.” Blum está actualmente usando GeMS para estudiar los ambientes dentro y alrededor de los cúmulos estelares, y sus datos preliminares que apuntan al espectacular cúmulo conocido como RMC 136 y que se encuentra dentro de un set de siete imágenes publicadas hoy. Las seis imágenes restantes – vistas que atraviesan desde violentas regiones de formación estelar hasta la interacción de galaxias distantes que chocan–– solo dan una pista de la diversidad de las investigaciones más avanzadas que permite realizar GeMS.

Obtener la misma nitidez desde la Tierra que un telescopio ubicado en el espacio ya es posible. Un nuevo sistema resuelve uno de los mayores problemas de los telescopios terrestres: la distorsión de las imágenes espaciales. La atmósfera tiene varias capas con distintas temperaturas y presiones, lo que provoca que la luz, al atravesarla, se distorsione y las imágenes se vean rodeadas de turbulencia. En el Observatorio Gemini han dado con una técnica revolucionaria que produce imágenes con una resolución espacial similar a la que se logra con un telescopio orbital.

GRB Lights Up Ancient Hidden Galaxy

August 7, 2013 - Universe Today
Once upon a time, more than 12.7 billion years ago, a star was poised on the edge of extinction. It made its home in a galaxy too small, too faint and too far away to even be spotted by the Hubble Space Telescope. Not that it would matter, because this star was going to end its life before the Earth formed. As it blew itself apart, it expelled its materials in twin jets which ripped through space at close to the speed of light – yet the light of its death throes outshone its parent galaxy by a million times.

Comet ISON continues to foreshadow its close pass of the Sun later in the year - Hawaii's Gemini Observatory snapped these images of ISON crossing the sky in early February, March, April and May. It will pass within 1.2m km of the Sun in November, and could be the "comet of the century" if it does not burn up entirely on the way.

Why gamma-ray burst shocked scientists
http://www.cnn.com/2013/05/06/opinion/urry-gamma-ray-burst/index.html
May 6, 2013 - CNN.com
On April 27, NASA's Fermi and Swift satellites detected a strong signal from the brightest gamma-ray burst in decades. Because this was relatively close, it was thousands of times brighter than the typical gamma-ray bursts that are seen by Swift every few days. Scientists are now scrambling to learn more.
...
Thanks to observations made with the Gemini ground-based optical telescope in Hawaii, it quickly became clear that GRB130427A was superbright primarily because it lay only a few billion light years away. Had it been situated in a much more distant galaxy -- as many gamma-ray bursts are -- its signal would have been relatively feeble.

Chile Pins High-Tech Hopes on Heavens
http://online.wsj.com/article/SB10001424127887323628004578457203414317068.html
May 2, 2013 - Wall Street Journal
The desert here, with its pristine skies and bone-dry climate, is luring a bounty of the world's stargazers and raising hopes Chile can reap a boon in research and development and high-tech industry.
Investments in the astronomy sector are well under way and expected to reach nearly $6 billion by the end of this decade, giving northern Chile about 70% of the world's astronomical observatories. Astronomers say the extreme aridness and lack of light pollution there gives them less atmospheric distortion than elsewhere in the world.
"In the last five years, there have been on average 280 to 300 clear nights a year," said Rodrigo Carrasco, an assistant astronomer at the Gemini Observatory in La Serena in northern Chile's Atacama Desert. "That's higher than anywhere else and it's a particularity of the Chilean skies."

Dying Supergiant Stars Implicated in Hours-Long Gamma-Ray Bursts
http://www.sciencedaily.com/releases/2013/04/130416180032.htm
April 16, 2013 - ScienceDaily.com
Three unusually long-lasting stellar explosions discovered by NASA's Swift satellite represent a previously unrecognized class of gamma-ray bursts (GRBs). Two international teams of astronomers studying these events conclude that they likely arose from the catastrophic death of supergiant stars hundreds of times larger than the sun.
...
Using the Gemini North Telescope in Hawaii, Levan and his team obtained a spectrum of the faint galaxy that hosted the Christmas burst. This enabled the scientists to identify emission lines of oxygen and hydrogen and determine how much these lines were displaced to lower energies compared to their appearance in a laboratory. This difference, known to astronomers as a redshift, places the burst some 7 billion light-years away.

Astronomer Locates Previously Unseen Neighbor to the Sun

March 11, 2013 - Scientific American
When NASA launched the WISE satellite in 2009, astronomers hoped it would be able to spot loads of cool, dim objects known as brown dwarfs. Bigger than a planet, a brown dwarf is not quite a star, either—it is too small to sustain the nuclear fusion reactions that turn hydrogen to helium. But it may burn to some degree, using a heavy isotope of hydrogen called deuterium as fusion fuel.

Extreme Exoplanet-Hunting Telescope to Go Online This Fall
http://www.wired.com/wiredscience/2013/02/extreme-exoplanet-hunter/
February 23, 2013 - Wired.com
The search for exoplanets is about reach the next level with the Gemini Planet Imager, a new smart-car-sized telescope instrument that will use “extreme” adaptive optics to directly see distant planets around other stars.
Most large telescopes on Earth use adaptive optics — mirrors that wiggle a thousand times a second — to compensate for distortion from the atmosphere that causes the familiar “twinkling” effect of stars. With the technology, fuzzy globs of starlight are transformed into sharp pinpoints. GPI will take the method a step farther, using a mirror made from advanced silicon microelectromechanical systems (MEMS) instead of glass.
