Pasadena, CA – Astronomers using NASA’s Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter’s moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.
The observation increases the possibility that missions to Europa may be able to sample Europa’s ocean without having to drill through miles of ice.
“Europa’s ocean is considered to be one of the most promising places that could potentially harbor life in the solar system,” said Geoff Yoder, acting associate administrator for NASA’s Science Mission Directorate in Washington. “These plumes, if they do indeed exist, may provide another way to sample Europa’s subsurface.”

Washington, D.C. – NASA will host a teleconference at 1:00pm CDT Monday, September 26th, to present new findings from images captured by the agency’s Hubble Space Telescope of Jupiter’s icy moon, Europa.
Astronomers will present results from a unique Europa observing campaign that resulted in surprising evidence of activity that may be related to the presence of a subsurface ocean on Europa.

Pasadena, CA – NASA’s Juno spacecraft has sent back the first-ever images of Jupiter’s north pole, taken during the spacecraft’s first flyby of the planet with its instruments switched on. The images show storm systems and weather activity unlike anything previously seen on any of our solar system’s gas-giant planets.
Juno successfully executed the first of 36 orbital flybys on August 27th when the spacecraft came about 2,500 miles (4,200 kilometers) above Jupiter’s swirling clouds.

Pasadena, CA – Our galaxy is home to a bewildering variety of Jupiter-like worlds: hot ones, cold ones, giant versions of our own giant, pint-sized pretenders only half as big around.
Astronomers say that in our galaxy alone, a billion or more such Jupiter-like worlds could be orbiting stars other than our sun. And we can use them to gain a better understanding of our solar system and our galactic environment, including the prospects for finding life.
It turns out the inverse is also true — we can turn our instruments and probes to our own backyard, and view Jupiter as if it were an exoplanet to learn more about those far-off worlds.

Pasadena, CA – NASA’s Juno mission successfully executed its first of 36 orbital flybys of Jupiter today. The time of closest approach with the gas-giant world was 6:44am PDT (8:44am CDT, 13:44 UTC) when Juno passed about 2,600 miles (4,200 kilometers) above Jupiter’s swirling clouds.
At the time, Juno was traveling at 130,000 mph (208,000 kilometers per hour) with respect to the planet. This flyby was the closest Juno will get to Jupiter during its prime mission.
“Early post-flyby telemetry indicates that everything worked as planned and Juno is firing on all cylinders,” said Rick Nybakken, Juno project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California.

Washington, D.C. – This Saturday at 5:51am PDT, (7:51am CDT, 12:51 UTC) NASA’s Juno spacecraft will get closer to the cloud tops of Jupiter than at any other time during its prime mission.
At the moment of closest approach, Juno will be about 2,600 miles (4,200 kilometers) above Jupiter’s swirling clouds and traveling at 130,000 mph (208,000 kilometers per hour) with respect to the planet. There are 35 more close flybys of Jupiter scheduled during its prime mission (scheduled to end in February of 2018).

Greenbelt, MD – Launched five years ago on August 5th, 2011, NASA’s Juno mission maneuvered into orbit around Jupiter on July 4th, 2016, joining a long tradition of discovery at the gas giant.
One of the brightest objects in the night sky, Jupiter has enthralled humans since ancient times. Today, scientists believe that learning more about the planet may be the key to discovering our solar system’s origins and formation.
Washington, D.C. – Jupiter’s volcanic moon Io has a thin atmosphere that collapses in the shadow of Jupiter, condensing as ice, according to a new study by NASA-funded researchers. The study reveals the freezing effects of Jupiter’s shadow during daily eclipses on the moon’s volcanic gases.
“This research is the first time scientists have observed this remarkable phenomenon directly, improving our understanding of this geologically active moon,” said Constantine Tsang, a scientist at the Southwest Research Institute in Boulder, Colorado. The study was published August 2nd in the Journal of Geophysical Research.

Pasadena, CA – Five years after departing Earth, and a month after slipping into orbit around Jupiter, NASA’s Juno spacecraft is nearing a turning point. On July 31st at 12:41pm PDT (3:41pm EDT), Juno will reach the farthest point in its orbit of Jupiter for the first time, known as “apojove,” 5 million miles (8.1 million kilometers) from the giant planet.
After that point, Jupiter’s gravitational grip on Juno will cause the spacecraft to begin falling back toward the planet for another pass, this time with its scientific eyes wide open.

Washington, D.C. – NASA’s Juno is now poised to shine a spotlight on the origins and interior structure of the largest planet in our solar system.
As we wait for Juno’s first close-up images of Jupiter (to be taken August 27th during the spacecraft’s next pass by the planet), NASA continues to explore our solar system to help answer fundamental questions about how we came to be, where we are going and whether we are alone in the universe.
