By Monday afternoon, the fire had grown to 4,871 acres and remained 0% contained — numbers that remained unchanged into the night.

The Mount Wilson Observatory houses 18 telescopes, many of which were used to make some of the greatest astronomical discoveries of the last century.

They include the 100 inch Hooker telescope that Edwin Hubble used in the 1920s to prove that our universe is still expanding.

Observatory Director Tom Meneghini said he's afraid they could be seriously impacted if the fire gets close enough.

“The heat can do irreparable damage. Our two big telescopes are historically significant and irreplaceable,” Meneghini said.

However, he said fires have gotten close before and the decades-old firefighting setup at the Observatory is ready to be used again.

"We have an inground system of hoses and pumps," he said. "We have half a million gallons of water ready to pump so that’s all been prepared for any fire professional to come in and take over."

The fire also threatens a seismic station that has recorded earthquake activity for 100 years, seismologist Lucy Jones said via Twitter.

Thick smoke has made the sun appear red in some places and cast an ominous orange glow over the region.

Across Southern California, the air quality level is projected to be moderate to unhealthy for sensitive groups. Bottom line: If you can see it or smell it, then you should take precautions. Stay indoors and check the current air quality before attempting outdoor activities.
