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.
Gemini Observatory provides critical rapid follow up observations of a Fast Radio Burst – one of modern astronomy's greatest enigmas. These observations provide the first details on a burst's distant extragalactic host.
A new image released today by the Gemini Observatory offers a deep, revealing view into an active stellar nursery known as GGD 27. The infrared view peels back layers of obscuring gas and dust to unshroud the inner workings of star formation.
Using spectroscopic data from the Gemini North telescope, researchers have probed a complex binary T Tauri system that hints at a hidden planetary body shrouded deep within a stellar environment at the late stages of formation.
Astronomers using critical observations from the Gemini Observatory have found the strongest evidence yet that the formation of more massive stars follow a path similar to their lower-mass brethren - but on steroids!
A team using the Gemini Multi-Conjugate Adaptive Optics System (GeMS) with the Gemini South Adaptive Optics Imager (GSAOI) have, for the first time, measured the stellar masses relative to the physical sizes of several galaxies in a cluster at a lookback time of about 5 billion years.
Jupiter’s moon Io is the most volcanically active world in our Solar System. Now, the longest series of frequent high-resolution tracking of Io’s thermal emission is providing insights on Io’s volcanoes thanks to a powerful joint observation program between the Gemini North telescope (with NIRI+Altair instrument) and the W.M. Keck Observatory.
An international team of astronomers, using the Gemini Multi-conjugate adaptive optics System (GeMS) and the high resolution camera GSAOI, brought the ancient globular cluster NGC 6624 into razor-sharp focus and determined its age with very high accuracy － a challenging observation even from space.
Astronomers studying a mysterious phenomenon known as Lyman-alpha blobs (LABs) have discovered several of these high-energy objects in galaxies that are much closer than previously known. The discovery is significant because these closer specimens are much easier to study, and because they live at a time when the Universe was much older and more mature, allowing astronomers to study their evolution with cosmic time
Using the W. M. Keck Observatory and the Gemini North telescope – both on Maunakea, Hawai‘i – astronomers found a galaxy whose mass is almost entirely Dark Matter.
Gemini explores the possibility of short-lived optical emission (visible light) from the violent events that produce gravitational waves.
Gemini observations show that the thin atmosphere of Jupiter's moon Io undergoes dramatic changes during frequent eclipses with the giant planet.
Gemini Observatory plays a key role in the latest harvest of over 100 confirmed exoplanets from NASA’s K2 mission, the repurposed Kepler spacecraft. Three instruments on the Gemini North telescope delivered precise images verifying many of the candidate stars as planetary system hosts. Researchers note that these systems could contain a considerable number of rocky, potentially Earth-like exoplanets.
As the Juno mission begins exploring Jupiter in our Solar System, scientists explore a solo world that researchers say looks more similar to Jupiter than any exoplanet yet discovered.
The novel collaboration between the Gemini Observatory and Canada-France-Hawai‘i Telescope (CFHT) called GRACES (Gemini Remote Access to CFHT ESPaDOnS Spectrograph), helped to characterize a “hot Jupiter” around the T-Tauri star V830 Tau.
The world’s most advanced adaptive optics system reveals “shocking” details on star formation in a new image released by the Gemini Observatory probing a swarm of young and forming stars that appear to have been shocked into existence.
Using the Gemini Planet Imager astronomers have successfully monitored the motion of a planet around the forming exoplanet system orbiting the star HD 95086 and suggest that more unseen planets are present.
Before low-medium mass stars become white dwarfs they pulsate wildly and eventually spew their outer layers into space – often forming beautiful planetary nebulae. The same stars are predicted to continue pulsating during their transformation to a white dwarf, if they have helium in their atmospheres.
Using the FLAMINGOS-2 spectrometer/imager at Gemini South, astronomers have characterized an especially young, free-floating analogue to Jupiter in our neighborhood (92 light years away).
Astronomers using the 8-meter Gemini North telescope on Hawaii’s Maunakea have probed an enigmatic, and unexpected, supermassive black hole dominating the core of a large galaxy in the cosmic backwaters.
