Summary: International Observe The Moon Night 2019

10 years after the first NASA sponsored International Observe The Moon Night Event, and 5 decades after the Apollo 11 astronauts first set foot on the surface of the Moon, we’re proud to report the largest International Observe The Moon Night event, EVER, at UCLA thanks to help from volunteers from UCLA’s Earth, Planetary, and Space Sciences, and Physics and Astronomy Departments.

Just short of ~1000 visitors were entertained by experts in astronomy answering questions and showing views of the Moon, Jupiter, and Saturn. This was the largest ever International Observe The Moon Night event held by UCLA, and a number growing each year. Many of those in attendance had never seen a celestial body through a telescope.

Please see the recap below by UCLA Professor Dr. David Jewitt, Dr. Jing Li, and Emmanuel Masongsong:

Many thanks to the UCLA EPSS Paige, & Jewitt Groups, as well as the Physics and Astronomy Rich Group, NASA’s Jet Propulsion Laboratory, and Fox Searchlight for offering their support, artifacts, and giveaways for the public.

See you in 2020 for IOTMN 2020!

UCLA Professor David Jewitt Leading New Studies on The Second Interstellar Visitor to Our Solar System

UCLA Professor Dr. David Jewitt is at the forefront of the newest study on an interstellar comet visiting the solar system. While you may remember that ‘Oumuamua (A/2017 U1 & aka 1/I ‘Oumuamua) passed into the solar system in 2017, a recent discovery by Gennadiy Borisov suggests this object is completely unbounded to the Sun with an eccentricity of ~3.5 and is the first interstellar comet, ever detected. This suggests a highly energetic object, unbound to the Sun which may have came from another planetary system.

In a new Popular Mechanics Article (c.f. https://www.popularmechanics.com/space/deep-space/a29091084/comet-photos-2019/) , Dr. Jewitt mentioned: “The most excellent thing about these objects is the number of them”

“We’ll detect more of them as time goes on,” he says. “It’s already good that we got the second [comet] pretty much on schedule.”

This suggests more of these objects are able to be detected by our instruments on the Earth, and in space.

The future looks promising for Planetary Science as well as welcoming more and more of these interstellar visitors to our own solar system.

In the days to come, we will learn more about the composition of volatiles coming from comets in other systems, as well as our our solar system from researchers at UCLA, and all over the world leading the way.

Early Monday morning, the moon was the closest it has been to Earth since 1948 and it appeared 30 percent brighter and 14 percent bigger than the average monthly full moon.

UCLA Astronomers Confirm the Very First Existence of an Asteroid Beyond Our Solar System

CAPE CANAVERAL, Fla. — A newly discovered object from another star system that’s passing through ours is shaped like a giant pink fire extinguisher.

That’s the word this week from astronomers who have been observing this first-ever confirmed interstellar visitor.

“I’m surprised by the elongated shape – nobody expected that,” said astronomer David Jewitt of the University of California, Los Angeles, who led the observation team that reported on the characteristics.

Scientists are certain this asteroid or comet originated outside our solar system. First spotted last month by the Pan-STARRS telescope in Hawaii, it will stick around for another few years before departing our sun’s neighborhood.

Jewitt and his international team observed the object for five nights in late October using the Nordic Optical Telescope in the Canary Islands and the Kitt Peak National Observatory near Tucson, Arizona.

At approximately 100 feet by 100 feet by 600 feet (30 meters buy 30 meters by 180 meters), the object has proportions roughly similar to a fire extinguisher — though not nearly as red, Jewitt said Thursday. The slightly red hue — specifically pale pink — and varying brightness are remarkably similar to asteroids in our own solar system, he noted.

Astronomer Jayadev Rajagopal said in an email that it was exciting to point the Arizona telescope at such a tiny object “which, for all we know, has been traveling through the vast emptiness of space for millions of years.”

“And then by luck passes close enough for me to be able to see it that night!”

The object is so faint and so fast — it’s zooming through the solar system at 40,000 mph (64,000 kph) — it’s unlikely amateur astronomers will see it.

In a paper to the Astrophysical Journal Letters, the scientists report that our solar system could be packed with 10,000 such interstellar travelers at any given time. It takes 10 years to cross our solar system, providing plenty of future viewing opportunities, the scientists said.

Trillions of objects from other star systems could have passed our way over the eons, according to Jewitt.

It suggests our solar system ejected its own share of asteroids and comets as the large outer planets — Jupiter, Saturn, Neptune — formed.

Why did it take so long to nail the first interstellar wanderer?

“Space is big and our eyes are weak,” Jewitt explained via email.

Anticipating more such discoveries, the International Astronomical Union already has approved a new designation for cosmic interlopers. They get an “I” for interstellar in their string of letters and numbers. The group also has approved a name for this object: Oumuamua (OH’-moo-ah-moo-ah) which in Hawaiian means a messenger from afar arriving first.

NASA’s Hubble Observes the Farthest Active Inbound Comet Yet Seen

UCLA’s Professor David Jewitt has most recently been involved in using NASA’s Hubble Space Telescope to image the farthest active inbound comet yet seen.

The Comet that Came in from the Cold

A solitary frozen traveler has been journeying for millions of years toward the heart of our planetary system. The wayward vagabond, a city-sized snowball of ice and dust called a comet, was gravitationally kicked out of the Oort Cloud, its frigid home at the outskirts of the solar system. This region is a vast comet storehouse, composed of icy leftover building blocks from the construction of the planets 4.6 billion years ago.

The comet is so small, faint, and far away that it eluded detection. Finally, in May 2017, astronomers using the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) in Hawaii spotted the solitary intruder at a whopping 1.5 billion miles away – between the orbits of Saturn and Uranus. The Hubble Space Telescope was enlisted to take close-up views of the comet, called C/2017 K2 PANSTARRS (K2).

The comet is record-breaking because it is already becoming active under the feeble glow of the distant Sun. Astronomers have never seen an active inbound comet this far out, where sunlight is merely 1/225th its brightness as seen from Earth. Temperatures, correspondingly, are at a minus 440 degrees Fahrenheit. Even at such bone-chilling temperatures, a mix of ancient ices on the surface – oxygen, nitrogen, carbon dioxide, and carbon monoxide – is beginning to sublimate and shed as dust. This material balloons into a vast 80,000-mile-wide halo of dust, called a coma, enveloping the solid nucleus.

Astronomers will continue to study K2 as it travels into the inner solar system, making its closest approach to the Sun in 2022.

UCLA EPSS Prof. Margaret Kivelson Wins American Astronomical Society’s 2017 Gerard P. Kuiper Prize

UCLA EPSS Professor Margaret Kivelson Wins American Astronomical Society’s 2017 Gerard P. Kuiper Prize
UCLA EPSS Professor Margaret Kivelson has won the 2017 Gerard P. Kuiper Prize, the highest award given to planetary scientists from the American Astronomical Society’s Division For Planetary Sciences. The Kuiper Prize is given for Outstanding Contributions to Planetary Science.
From the AAS news release:

“The Gerard P. Kuiper Prize for outstanding contributions to planetary science goes to Margaret G. Kivelson (University of California, Los Angeles, and University of Michigan) for her work studying Jupiter’s magnetospheric plasmas to understand the interiors of planets and their moons. Kivelson’s pioneering discoveries of an ocean inside Jupiter’s moon Europa and a magnetic field generated by neighboring Ganymede showed us that these icy bodies are not inert but dynamic worlds. Her insights have spurred us to recognize that habitability need not depend on proximity to the Sun in the traditional habitable zone. As a direct result of Kivelson’s advancements, we now recognize that the ocean worlds of the outer solar system may represent our best chances for discovering life beyond Earth.”

Congratulations Professor Kivelson!
