Gemini South confirms long-suspected link between the composition of exoplanets and their host stars

Astronomers have discovered that a giant planet, WASP-189b, echoes the composition of its host star, providing the first direct evidence of a foundational concept in astrobiology....

A New Eye Opens at the Top of the World.

Thirty four years ago, a group of Cornell scientists looked at a remote Chilean mountaintop and imagined what might be built there one day. That day has arrived. The Fred Young Sub...

Major new telescope on Chilean summit opens window on universe

Thirty-four years after Cornell University scientists first conceived it, the Fred Young Submillimeter Telescope (FYST) now rises above the Atacama Desert, near the summit of Cerro...

Gemini for Science: AI experiments and tools for a new era of discovery

Gemini for Science is a new collection of science tools and experiments to expand the scale and precision of scientific exploration.

Webb eyes a pair of planet-forming disks

This month's NASA/ESA/CSA James Webb Space Telescope Picture of the Month offers us a two-for-one on brand new stars—with some potential planets thrown in as well. This visual hi...

The Paranal solar ESPRESSO Telescope, a New Tool for Finding Exoplanets

The Paranal solar ESPRESSO Telescope (PoET), installed at the European Southern Observatory's (ESO's) Paranal site in Chile, has made its first observations. The telescope will wor...

20,000 Eyes on the Universe

We live in a golden age of astronomical imaging. Telescopes are capturing billions of galaxy images, painting the universe in breathtaking detail. But there's a problem, and it's a...

Gaze into the Crystal Ball Nebula and see the light emitted by a dying star 1,500 years ago

The 8.1-meter Gemini North telescope, located on the summit of Maunakea in Hawai'i, has captured NGC 1514, nicknamed the Crystal Ball Nebula, in awe-inspiring detail. This nebula,...

Between eternal night and day, the faces of two cousins of Earth

An international team including the University of Bern (UNIBE) and the University of Geneva (UNIGE), members of the National Center of Competence in Research PlanetS, has succeeded...

Antarctic telescope spies alien worlds with ever-shifting orbits

My new toy - Astronomy telescope

Have a look at LNB 744 and SH 2-221. They look pretty good in Stellarium and are about the same elevation as the Jellyfish Nebula and higher than Orion. I’m going to try 2 hours wi...

Exoplanet Host Star Shares Elemental Traits with Its Hot Jupiter

An ultra-hot Jupiter exoplanet orbiting a nearby star gave scientists using the Gemini South telescope a look at how both a star and its hot planet can have similar chemical compos...

My new toy - Astronomy telescope

Second night in a row with clear skies! Whoopee! So last night we had a go at M81 and M82 with the Dwarf 3 - Bode’s galaxy* and the Cigar galaxy. ( Discovered by Johann Elert Bode...

My new toy - Astronomy telescope

hairbear: Have a look at LNB 744 and SH 2-221. Thank you! Is there another designation for LNB 744? I can’t find that in Stellarium, or Google. SH 2-221 shows up in Stellarium b...

First light for PoET: shining (sun)light on exoplanet research

The Paranal solar ESPRESSO Telescope (PoET), installed at the European Southern Observatory's (ESO's) Paranal site in Chile, has made its first observations. The telescope will wor...

My new toy - Astronomy telescope

ChrisMann: Is there another designation for LNB 744? Yes indeed … LBN 744 . My misspelling. It’s actually next door to SH 2-221. Probably both a bit dimmer than Rosette Nebula,...

The Gemini recalibration

My new toy - Astronomy telescope

LBN 744 is a planetary nebula and may not be suitable for use with the Ha/OII filter.

My new toy - Astronomy telescope

hairbear: I see the Dwarf 3 has built in filters. Didi you use any of them yet ? Yes I used the dual narrow-band filter on the Orion and Rosette nebulae. It seemed to be a good...

Cosmic collision of galaxies mapped by Maunakea telescope

An astronomer at the University of Hawaiʻi at Hilo is using data from the Canada–France–Hawaiʻi Telescope (CFHT) on Maunakea to help reconstruct a slow-motion cosmic collisio...
