A Runaway Star in the Small Magellanic Cloud

In a drama taking place in the Small Magellanic Cloud, a close companion galaxy to the Milky Way, a rare star is speeding out of the galaxy at 300,000 miles per hour. The first runaway yellow supergiant star ever discovered, and only the second evolved runaway star found in another galaxy, the star was once a member of a binary star system and was ejected at high speed when its companion star exploded as a supernova. The discovery was made using the CTIO 4-m Blanco telescope.

New Chapter Begins for Kitt Peak Telescope

Forty-five years ago this month, the 4-m Mayall began its career as an “all-purpose research tool” with the inspection of its first images by then KPNO Director Nicholas Mayall (inset). The telescope now turns to a new mission: creating the largest 3D map of the cosmos. Over the next 15 months, the telescope will prepare for the installation of the Dark Energy Spectroscopic Instrument, an ultra-high-tech optical spectrometer capable of measuring the spectra of 5000 astronomical objects simultaneously.

New Chapter Begins for Kitt Peak’s 4-m Mayall

Its 45-year-long assignment as an “all-purpose research tool” completed, the Mayall now embarks on a new mission: creating the largest 3D map of the cosmos. The map will help chart out the role of dark energy in the expansion history of the Universe. Over the next 15 months, the telescope will prepare for the installation of the Dark Energy Spectroscopic Instrument, a massively parallel optical spectrometer capable of measuring the spectra of 5000 astronomical objects simultaneously.

New Stellar Streams Confirm ‘Melting Pot’ History of the Galaxy

While most stars in the Milky Way were likely born here, many appear to have originated in other galaxies and migrated to our shores. Tell-tale evidence comes from streams of stars created when small galaxies interact with the Milky Way. Eleven new stellar streams, discovered in data from the Dark Energy Survey, currently in progress at the CTIO Blanco telescope, provide new evidence for this picture. The public release of the survey data continues the trend toward “Big Data” in astronomy.

Rivers in the Sky
New stellar streams named for water-related words from Chile, India, and Australia

While most stars in the Milky Way were likely born here, many appear to have originated in other galaxies and migrated here in streams of stars created when small galaxies interact with the Milky Way. Some of the new stellar streams discovered by the Dark Energy Survey, currently in progress at the CTIO Blanco telescope, have been named by Chilean children for bodies of water close to home (Lea en español). Others have been named for rivers in India and Australia.
