Another find from our archives! 🔭
In 1968, a Carnegie team hiked a bare Chilean peak above the high Atacama to decide if it would be a good home for an observatory. This collection of photos captures the trip.

This total solar eclipse appeared not only poetically beautiful but scientifically interesting. Usually the solar corona appears white, and to some observers the corona of last week's total solar eclipse did appear this pearly color. But this time, totality observers in Spain saw a corona that appeared unusually golden. For one reason, from Spain, the totality occurred when the setting Sun was near the horizon. That low, sunlight travels through a large amount of air which scatters out blue light. An unusual amount of smoke in the air from nearby forest fires acted as a second filter, further scattering the remaining blue tones and deepening the already gold-dominated light. The HDR-processed, multiple-exposure featured image was captured from Benavente, Spain last week. One thing that did not appear golden was a hydrogen-glowing prominence that hovered over the Sun's left edge -- its original bright pink color survived.

Every total solar eclipse is unique. The one on August 12—which occurred at dusk, just before sunset—revealed changes in the light of indescribable beauty. It is impossible to capture those changes in a image, but this one by Javier Castro (via @shaqt3) offers an incredible view.

🚐🌵 In the 1970s, Carnegie scientists drove a mobile home into Death Valley. The lab on wheels helped study a plant that did its best photosynthesis at 117°F.
The Desert Mobile Lab (+ this very 70s photo set) make up our 20th #Carnegie125 object.

A cosmic "lighthouse" calls the center of the Crab Nebula home.
Known as a pulsar, this rapidly spinning neutron star sends off beams of radiation that sweep through space.

Colorful gas filaments appear to splash outward from the nebula center, colored yellow, magenta, and blue.

Last week, Carnegie President John Mulchaey & author George Hammond joined @cwclub to discuss science history, next-gen telescopes (@giantmagellan), & the future of U.S. astronomy.
The takeaway? Continued U.S. leadership is a decision—not a given! 👏

Happy birthday to Robert S. Woodward—Carnegie's second president and "the first modern manager of science." His portrait is Object 18 in our #Carnegie125 series.
Learn how his approach got Andrew Carnegie to double down on his investment in science. ⬇️

57 years ago today, Apollo 11 landed on the Moon and the rock samples the team collected rewrote planetary science. The samples are still teaching us today.
Here are three things we learned from Apollo: bit.ly/3TpUon1

One giant leap for mankind
History was made on July 20, 1969, when Apollo 11's Neil Armstrong and Buzz Aldrin became the first to set foot on the Moon.
For more than 5 decades, the total number of moonwalkers has remained at 12. NASA will change that with Artemis IV.

They found what they were looking for in 2024, using the WINERED spectrograph on the Magellan Clay telescope at Carnegie's Las Campanas Observatory in Chile (@LCOAstro.)

Beyond telescopes, Carnegie's @LCOAstro brings astronomy to communities across Chile through school visits, teacher training, accessible resources, dark-sky education, & hands-on science programs.

Lunar halo above the dome of Baade 6.5-m Magellan telescope at Carnegie Las Campanas in the Atacama desert in Chile 🇨🇱 I captured this image a while ago and what a sight it was ! 🤩 A lunar halo is a bright ring of light (often 22° in radius) encircling the Moon, formed when moonlight is refracted and dispersed through hexagonal ice crystals in high-altitude cirrus or cirrostratus clouds.

Venus and Jupiter shining right above the telescope at Carnegie Las Campanas Observatory in the Atacama desert in Chine. I took this image soon after sunset, when the colors suddenly fired up high in the sky. Such a serene scene ! Although such weather is quite a challenge for us astronomers, it’s moments like this that make it all worth it ✨

Clouds have finally arrived in the Atacama desert in Chile ☁️ Looks like we are going to have challenging observations tonight …
