Google's newest homepage Doodle celebrates Guillermo Haro, a Mexican astronomer who became the first Mexican in 1959 to be elected to the Royal Astronomical Society.

Today (March 21) Haros would have been 105 years old. He (along with the astronomer George Herbig) gives his name to Herbig-Haro objects, glowing arcs and patches of light that come from baby stars that create shock waves when they blast high-speed material jets into the surrounding gas. The relatively short-lived objects point the way to the newborn stars of the universe. He also discovered bright, changeable stars, which in the Orion constellation are called flare stars, which can then unexpectedly increase their brightness for minutes.

  This image from Herbig-Haro object HH ​​46/47 combined with the Atacama Large Millimeter captured radio observations / sub-millimeter array (ALMA) with much shorter wavelength visible light Observations by ESO New Technology Telescope (NTT). The ALMA observations (orange and green, lower right) of the newborn star reveal a large energetic beam that moves away from us, obscured by dust and gas in the visible. On the left (in pink and violet) you can see the visible part of the jet, which partially flows towards us.

The ALMA observations (orange and green, lower right) of the newborn star reveal a large energetic beam that moves away from us, obscured by dust and gas in the visible. On the left (in pink and purple) you can see the visible part of the jet, which flows partly to us.

"Haro was born in Mexico in 1913, grew up during the Mexican Revolution, and studied philosophy before starting a career in astronomy," Google spokesmen wrote in a blog post. "Haro's legacy continues today through the National Institute for Astrophysics, Optics and Electronics, which he founded to support science students in their careers, and runs an observatory named after him in the Mexican state of Sonora."
