Gemini Planet Imager

A parsec is the distance — 3.26 light-years — that a star must lie from the Sun for its parallax angle to be exactly 1 arcsecond (1/3600 of a degree). astronomy.com/magazine/ask-a…

From @briles_34: Curious about what polarimetry is, and how it can help us understand the universe? This guide is for you! astrobites.org/2022/10/23/ast… feat. science cases & results from @PlanetImager @ehtelescope @almaobs @sofiatelescope and more

GPI (2) has got a brand new look! Testing out our adaptive optics on GPI's updated logo that features native Hawaiian geese, called nenes, in honor of GPI 2's future home at @GeminiObs North.

Why are we looking for life beyond Earth and how will we find it? Hear from astrobiologist K. Lynch, SETI researcher S. Sheikh, artist-in-residence B. Nelson, and planetary astronomer F. Marchis on possible answers. Vote for our SXSW Panel from Aug. 9-21! buff.ly/3vUDPRP

The dawn of a new era in astronomy has begun as the world gets its first look at the full capabilities of the NASA/ESA/CSA #JWST. The telescope’s first full-colour images and spectroscopic data were released today and they are spectacular. buff.ly/3P0kbuY

I have arrived at @NotreDame to be refurbished with a better WFS, new electronics and optics, so I reach a better sensitivity and contrast.

It’s happening… finally! @PlanetImager is going to @NotreDame to be upgraded and then will be shipped to @GeminiObs North to find more planets and image disks around young stars.

Beautiful observations with ALMA of a planetary cocoon around the planet PDS 70c where baby moons might be forming. It’s remarkable what can be seen with this facility on the top of the world. Congrats' to the team buff.ly/2W11ukb

What if there were a museum that contained every type of life form in the Universe? This @musicalscience video describes this fantastic place and gives us the opportunity to dream about them by mixing art and science. Enjoy this beautiful video! #SETI buff.ly/2FkUTsV

For the first time, astronomers have detected a planet orbiting a white dwarf star named WD 1856+534 (25pc from us). If further confirmed, the discovery shows that some planets could survive the destruction of their sun-like stars. buff.ly/3hHj3Lc

“Cosmic Conversation” Franck Marchis (@AllPlanets) of the @SETIInstitute and @ryanwyatt of the @calacademy to discuss direct imaging of Earth-like exoplanets—perhaps even the exoplanet closest to us, orbiting Proxima Centauri! buff.ly/2EgQ5ED

Animation of the solar system and moving outward to indicate stars observed with the Gemini Planet Imager (GPI) mounted on the Gemini South telescope in Chile. Highlighted are the images of the dusty rings encircling some of these young stars. buff.ly/3g1YoB9

Those are snapshots from the largest collection of sharp, detailed images of dusty debris disks around young stars. The images captured by Gemini @PlanetImager illustrate the variety of shapes and sizes that stellar systems can take during their infancy. buff.ly/37VRsCO

Astronomers released the largest collection of sharp, detailed images of debris disks around young stars, showcasing the variety of shapes & sizes of stellar systems during their prime planet-forming yrs. Surprisingly, nearly all showed evidence of planets buff.ly/3eyT48i

Dr. Jason Wang @semaphore_P of Caltech told us about the recent announcement that astronomers using the Near-Infrared Camera (NIRC2) on the Keck II telescope at W. M. Keck Observatory have directly imaged two infant gas giants: PDS 70b and PDS 70c. buff.ly/2UsBRp5
