“Light takes time to reach Earth’s observatories from the depths of space, and so you see objects and phenomena not as they are but as they once were. That means the universe acts like a giant time machine: the farther away you look, the further back in time you see—back almost to the beginning of time itself. Within that horizon of reckoning, cosmic evolution unfolds continuously, in full view.” — Neil deGrasse Tyson, Astrophysicist.

Intro

It’s called “The Big Ears” and it’s picking up naturally occurring signals from outer space. The Owens Valley Radio Observatory (OVRO) has a variety of antennas which are collecting these signals. Just as optical telescopes collect visible light waves, bring them into focus, amplify them and make them available for analysis, radio telescopes collect weak radio light waves, bring them into focus, amplify them and make them available for analysis.

OVRO is a research facility of the California Institute of Technology (Caltech). It was brought into operation in 1958 with one 32-ft radio telescope, which was built at the Caltech’s Palomar Observatory and relocated at the newly established OVRO. By early 1959, the first of two 90-foot antennas was operational and soon thereafter the second was listening to outer space.

90 footers. Then.

“The two 90-foot antennas of the radio interferometer at Owens Valley, shown here after the completion of the dishes in 1959, formed one of the largest and most sensitive radio telescopes in the world. Each dish alone was larger than any in the United States at that time.” ~ The Owens Valley Radio Observatory: Early Years by Marshall H. Cohen.

90 footers. Now.

In 1968 a 130-foot dish became operational at OVRO, which was originally intended to form part of an array of eight 130-foot dishes. But by the time the first dish was built, the National Science Foundation diverted funding to build twenty-seven 85-foot dishes in New Mexico. Nevertheless, the 130-foot dish at OVRO has produced valuable scientific results as a single dish as well as when it was paired with other radio telescopes around the world.

What Makes It Great

2018 marks 60 years of observation at the Owens Valley Radio Observatory. Little remains of that first 32-foot telescope, but the big dishes and numerous other telescopes, antennas, and arrays have expanded the reach and capacity of the facility. The scope of operation is extensive and world-class. OVRO now has the capability to ‘listen’ and analyze data using multiple different types of radio telescope technologies.

Looking to the sky. 130 foot dish.

The 130-foot telescope is still a vital instrument in radio astronomy 50 years after it was built. It is being used in conjunction with the Fermi Gamma-ray Space Telescope to monitor nearly 1200 blazars every two days – from right here in the Owens Valley.

The Long Wavelength Array (LWA) situated at OVRO is a low frequency interferometer that is working in conjunction with another LWA in New Mexico. Together these arrays are studying ‘The Dark Ages and Cosmic Dawn.” The Owens Valley LWA is currently the most powerful radio telescope in the world, which operates below 100MHz.

Another array, the Owens Valley Solar Array (OVSA), is one of the largest solar radio observatories in the United States. This project is a world-class facility for solar research at radio frequencies from 1-18 GHz. This is an area of national importance as scientists begin to understand the Sun’s influence on the Earth and near-Earth space environment – a subject broadly termed Space Weather.

The Deep Synoptic Array, which consists of ten fixed-position 15-foot dishes, is searching the sky for very short, powerful radio bursts called Fast Radio Bursts (FRBs). FRBs are enigmatic – we don’t know what causes them, how far away they are or even where they come from. Data from Deep Synoptic Array will allow astronomers to pinpoint the source of a FRB and help them figure out what creates them.

In what one of the astronomers calls ”the most technically challenging project we have ever done,” the CO Mapping Array Pathfinder (COMAP) uses a 34-foot dish to collect data to learn about galaxy formation in the early Universe. Further development of this project may see another four 10-meter dishes added for phase-2 of this study.

Who Is Going to Love It

This is a truly awesome facility to visit for aspiring and current scientists, astronomers, and anyone who has a keen interest in learning about our world – especially our extra-terrestrial world. A visitor could really ‘geek out’ at OVRO.

The beauty of this facility will not be lost on the less scientific and more artistic members of a family or school group. The location is incredibly beautiful with the majestic mountainous background on either side of these technological marvels. While much of the scientific data may be beyond the comprehension of most visitors, it is not hard to see how science and art are in perfect harmony out here in the high desert of the Owens Valley.

The Season

The Owens Valley Radio Observatory is operational year-round, and the facility offers free public tours on the first Monday of every month – unless it is a holiday, then the tour is on the second Monday. Tours begin at 1pm and last about an hour. Reservations are not required. Tours for school groups and large parties can be prearranged for other times by contacting OVRO at (760) 358-6410.

A series of public lectures is also offered by the researchers and educators in astronomy and astrophysics from OVRO. Lectures are held once a month from August to December and are geared towards any member of the community with an interest in the sciences. The lectures are presented at the Bishop campus of the Cerro Coso Community College.

“All that’s required is an inquisitive mind!” ~ OVRO

Original computers still in place, but now it runs through modern computers and programs.

Directions. Parking. Regulations.

Located southeast of Bishop, the Owens Valley Radio Observatory is 6 miles from the town of Big Pine. To get there, take US Highway 395 to just north of Big Pine and turn East onto State Route 168. Travel for 2½ miles then turn left onto Leighton Lane and go about 4 miles and through the gate. After a sharp left turn go about 100 yards and turn right on Robbie Road towards buildings #12 & #13. Tours start inside building #12 at the east end of the observatory. Detailed directions and maps are available here.

For the geeks in the group the coordinates for OVRO are 37:14:02N latitude, 118:16:56W longitude at 1222 meters above sea level.

This is Bishop from the Tungsten Hills looking east. Our little town is almost like an island. We have to travel hours to do most major shopping, or for any major medical issues. For most of us, it is absolutely worth it because we love the Eastern Sierra and although our town is small, our “backyard” is big and full of majestic natural beauty. We know many of you who live far away love this place as well. ❤️

So as you are making holiday plans this year, please remember to protect the people and places you love to play in. We appreciate it!!

We were campground hosts at Mammoth & went to Bishop for nice dinners on our days off, get haircuts, do laundry & see dentist. Enjoyed Bishop Mule Days too.. Besutiful area to spend the summer... Had to edit & add Schat's Bakery 💞💞

My first trip to Bishop was 57 years ago and have been back more years than not. I plan to keep coming back until my legs can’t walk the trails anymore. It’s truly a special place.

Wish I could be there. Great place to do star watching. Seem to be extra stars in the sky over there. Wishing you all the best for the holidays. Wish that bakery could deliver. So yummy. Stay well. <3

Loved growing up in Bishop, many fond memories there! I bet the town has changed since 75, but never the scenery!

One of my favorite places to camp don't how many times I've been there but I've been a bunch of times love it over 30times

I love it too! Grew up in Big Pine, worked in Bishop and Big Pine! 😊

best town I ever lived in

A place and time far far away! A place named Bishop, where I was born.

Take care! Hope to see you again next year!

Lived in early 50’s I lived in a mine camp Sheelite till the mud slide, moved to Rovanna To a mine housing . Parents bought a house in Tungsten City, up behind Rocking K Ranch, attended school in Round Valley Lots of memory In the area

Maybe you need to stop Blaming people that travel to the Eastern Sierra for your local problems. Its not really that small of a town and With the tax you get from tourism build a real medical facility and hospital!

My Dad grew up in Bishop, he actually worked at the Tungsten mines for awhile before heading to El Paso to go to college. Then the war started and he joined the Army Air Corps . I spent many a summers staying with my grandma Duffy, playing with my cousins in that magical place. Still my favorite place on earth.

Best place to grow up ‼️

Bishop is always one of our stopping points if we're visiting Yosemite and Death Valley. Bishop Creek Canyon, Rock Creek Canyon, Schats Bakery, Jacks, Spellbinder Books, Whiskey Creek- all previous haunts. Once normal travel arrangements return, we'll be back to visit one of our favourite places in the USA.

I know this viewpoint........magic.

I really miss Bishop and the Owens valley.....

Lived at Hilltop Estates/ Swall Meadows for quite a few years in the late 70’s to the early 80’s. Only place in California that keeps me coming back every couple years.

We would love to move there! Love the area.

Thank you for the words and picture you are blessed to live there xo

Our favorite place to go. Always come to the car show.

Home🇺🇸

To bad its in commiefornia. Love bishop

I remember Lone Pine too. Loved it

Small Town, Big Back Yard. 🥰

One of my favorite places on earth

I will take 1986. Had a cool uncle living there. Free lodging, and his Land Cruiser was available for deep snow drives.

Heck no...especially after I saw the video on "the old western hygiene". Talk about funk and stink! Whew, even the women stunk! Man-o-man....plus add on disease, diet and doctoring! Nope...lol 😆

I wonder if they still had to pose to get the exposure by 1886. Probably not.

Hmmm...1886 in Owens Valley? Was there a Sheriff? Or just a bunch of gun toting fools on horseback.

might be a sale but I will think it is a Halter class in the middle of the street and that will make me happy

Love that picture

I would love it. 🙏❤️🙏

I see Rusty’s!! Lol

It would be hard an cold but very free it would be something to go back in time

Every horse looks so healthy (extra shiny coat).... all that great pasture of the area > Owens Valley!

No thank you. I love Bishop, but I can't imagine living there without AC or a swamp cooler. lol

Even tho these days were hard ,they were free to enjoy great days.

Life was harder back then but better in My opinion.

Looks like a stock sale. If it were today, I would call it a horse show.

A busy place!

Early "Mule Days"?

I would buy that Appaloosa .

I would escape in a second :)

great pic

Right on

Can we visit but not stay?

Me

Great picture

Me toooooooo

Just an FYI. Seems fire season is still not over.
MONO COUNTY —U.S. Highway 395 in Mono County Due remains closed from Emigrant Street in Bridgeport to the Nevada State Line due to a wildfire in Walker Canyon. The fire has reached 20,800 plus acres and claimed 80 structures. It is unclear how long this section of the highway will be closed.

Drivers heading northbound on U.S. Hwy 395 should detour to either U.S. Hwy 6 just north of Bishop to NV360 to US 95 or State Route 182 in Bridgeport to Nevada 338. Southbound traffic from Nevada should detour to U.S. Hwy 95 to NV360 to U.S. Hwy 6 or Nevada 208 to Nevada 338 to State Route 182.

Hoping for an end to this nightmare. Time for some real rain and snow. Be safe. <3

Blah blah anything from keeping people away ! Come on people clear road a little hazy try and drive back east ! Quit whining!

We used to always camp with my parents at Bridgeport or Topaz lake years ago.

Tanner Ernst

Oh no!

These fires are never ending! Be safe.

Y'all stay safe!

Wow!

🙏🏻
