Updated: Dec 12, 2023 9:06 PM UTCPublished: Mar 21, 2018 1:04 PM UTC He may not be a household name, but Guillermo Haro is a star — at least as far as Google is concerned. [The March 21 Google Doodle](https://www.google.com/doodles/guillermo-haros-105th-birthday) is devoted to the vaunted Mexican astronomer, in honor of what would have been his 105th birthday. The celestial Doodle shows constellations spelling out Google’s name, with Haro’s face, illuminated in the night sky, serving as the second “O.” Here are five things to know about celebrated scientist Guillermo Haro. ## 1\. Guillermo Haro discovered Herbig-Haro objects Perhaps Guillermo Haro’s largest astronomical finding, and the one that bears his name, is the Herbig-Haro object. The term refers to planetary matter formed by the birth of a new star, [according to _Discover_ magazine](http://blogs.discovermagazine.com/badastronomy/tag/herbig-haro-objects/#.WrJOsxPwau4). ## 2\. …And flare stars in Orion’s Belt Orion’s Belt, a constellation made up of three sister stars, is among the most recognizable celestial shapes out there. We have Guillermo Haro to thank for discovering flare stars, or red and blue bright stars, near those that make up Orion’s Belt, as well in as several other areas, [according to the Royal Astronomical Society](http://adsabs.harvard.edu/full/1989QJRAS..30..493T). ## 3\. Guillermo Haro was the first Mexican elected to the Royal Astronomical Society Haro, who was born in Mexico in 1913, was honored for his contributions to the field of astronomy in 1959, when he became the first Mexican elected to the prestigious Royal Astronomical Society, according to Google. ## 4\. Haro advanced science in Mexico In 1960, Guillermo Haro became the first president of the brand new Mexican Academy of Sciences, an organization which he helped found, according to the Royal Astronomical Society. Haro also founded the [National Institute of Astrophysics, Optics, and Electronics,](http://www.inaoep.mx/en/) in 1971, to help support science students as they advance professionally, according to Google. ## 5\. Haro didn’t always plan to be an astronomer Despite his numerous contributions to the field of astronomy, Guillermo Haro actually graduated from the University of Mexico with a degree in philosophy. It was only after he graduated that he turned his interests to astronomy, paving the way for his career full of achievements. ## Transcript [ MUSIC ] For both astronomers and amateur sky watchers the great eclipse of 2017 is a wonderful cosmic freebie. It's the rare space phenomenal that can be fully observed and fully enjoyed entirely without an telescope. But for all other astronomical work Telescopes. The bigger, the better, remain the one indispensable tool. It's a good thing then that we're living in something of a boom time for telescope- building. And some of the best instruments are being deployed in one of two places. Chile or space itself. Not all of the country lends itself to telescope construction. But the Atacama Desert does, covering 40, 000 square miles of the Chilean coast, the Atacama is considered the driest place in the world. Cloudless at least 300 days a year. Combine that with a tenuous air of the desert's 13, 000 foot elevation and you get an almost completely clear window on the sky And that has brought the astronomers flocking. Currently, more than half a dozen radio telescope observatories from countries around the world are at work in the Atacama. Newest and most impressive is the Atacama Large Millimeter Array, a massive installation built by the United States, Canada, Taiwan, South Korea, and a consortium of European nations. The array consists of 66 separate radio dishes, and has the ability to expand to still more, all of them peering deep into space and far back in time. [ UNKNOWN ] Forward another foot please. As for the space- based observatories, the 800 pound gorilla is, of course, the Hubble Space Telescope. But Hubble is also an old gorilla, having been in orbit since 1990. With no more space shuttles to ferry up astronauts for occasional repair missions, Hubble is always just one significant malfunction away from going dark entirely The good news is that the vulnerable telescope is not alone. The most important and productive of the space flop include [ UNKNOWN ] Chandra X- Ray Observatory, the Swift Gamma- Ray Burst Explorer, and the celebrated Kepler Space Telescope which is being in the space since 2009. [ MUSIC ] More exiting is what's in the Pipeline especially the James Webb Space Telescope which will be launched in 2018. Web is the instrument that will take [ UNKNOWN ] place and it's upgrade in almost every way. From its 21 feet diameter mirror which dwells [ UNKNOWN ] 840 model to its ability in to do most of its observing in the infra red. Meaning it can peer straight through the clouds of interstellar dust that often obscure Hubble's view. None of these observatories, either in space or on the ground, will answer all of the questions human beings have about the universe. But the telescopes are expanding our view all the same, throwing back the curtain of the cosmos a little more. Free discovery they make.
