After the object was discovered by Pan-STARRS1 on Haleakala, both Gemini telescopes observed ‘Oumuamua for three nights as it quickly dimmed from view. Researchers found that despite its interstellar origin, the object is similar in composition to some objects in our Solar System but its shape is unlike anything found around our Sun.
Gemini North’s NIFS has confirmed the spiral nature of the most distant known spiral galaxy (A1689B11) by far through gravitational lensing.
Gemini Observatory "pulled all of the stops" to bring a gravitational wave source into focus and capture early optical and infrared light from the merger of two neutron stars.
Gemini astronomer Tom Geballe describes his recent infrared spectroscopic observations of a mysterious quintuplet of stars. Each of these stars is embedded in its own cocoon of dust in a cluster of massive stars near the center of the Milky Way.
Astronomers using the Gemini Observatory and the Canada-France-Hawaii Telescope have discovered remarkable differences in the abundance of heavier elements and the Lithium content in a binary star pair.
GRACES observes a fast-moving object that is likely a white dwarf star expelled from a supernova explosion and sent hurtling through our galactic neighborhood.
Gemini confirms a new class of variable stars called Blue Large-Amplitude Pulsators. They are significantly bluer than main sequence stars of the same luminosity demonstrating that they are relatively hot.
Spectroscopy using the Gemini Multi-Object Spectrograph on the Gemini South telescope in Chile verifies the extreme distance of one of the most distant superluminous supernovae ever studied.
Detailed Gemini Observatory images peel back Jupiter’s atmospheric layers to support the NASA/JPL Juno spacecraft in its quest to understand the giant planet’s atmosphere.
A team of Korean astronomers uses imaging from GMOS on Gemini North to characterize the rotation of active asteroid P/2010 A2’s largest fragment. The observations show that this faint and tiny asteroid, which underwent a mass ejection episode, is slowly rotating.
The first exoplanet discovered using the Gemini Planet Imager (GPI) is a young, cool object between 2–10 Jupiter masses. Research hints that the formation of this exoplanet is likely due to the collapse of icy disk materials followed by the accretion of a thick gas atmosphere.
Gemini Observatory astronomer Meg Schwamb is this year’s recipient of the Carl Sagan Medal for Excellence in Public Communication in Planetary Science. Schwamb is being honored for the creation and development of new tools and venues to facilitate planetary science communication.
On July 1, 2017, Dr. Laura Ferrarese begins a one-year term as Interim Director of the Gemini Observatory.
Researchers combine images from Gemini South’s wide-field adaptive optics system (GeMS/GSAOI) with data from the Hubble Space Telescope (HST) to determine the proper motion of a distant cluster of stars.
Gemini Observatory announces the development of a major new facility-class broadband optical and near-infrared imager and spectrograph named OCTOCAM.
The Gemini/CFHT observations help address ongoing questions and debates among scientists about Neptune’s migration from its primordial formation orbital location to its current locale.
Using the Gemini Planet Imager (GPI), a team of astronomers led by J. Chilcote (University of Toronto) found that the low mass stellar companion β Pictoris b is about 13 times more massive than Jupiter with a surface temperature of about 1720 K.
Using the Gemini Multi-Object Spectrograph (GMOS) on Gemini South, a team led by Jay Farihi (University College London) found, for the first time, a dust and debris disk surrounding a binary star with a white dwarf as a substellar companion. To date, almost all of the known planetary systems which include a white dwarf are single stars.
Gemini reached another significant milestone with the celebration of the official handover to Base Facility Operations (BFO) at Gemini South. About a year ago, Gemini North reached the same milestone, so now both Gemini telescopes operate routinely from the base facilities in La Serena, Chile and Hilo, Hawai‘i.
Gemini follows up on candidate galaxies with fading active galactic nuclei (AGN) first identified thanks to the Galaxy Zoo citizen science project. The gas clouds around these fading AGN are dominated by rotation, unlike those around radio-loud AGN, which are outflows coming from the nuclei.
