NASA’s Juno Spacecraft gets close up look at Jupiter’s Great Red Spot

NASA - National Aeronautics and Space AdministrationPasadena, CA – Images of Jupiter’s Great Red Spot reveal a tangle of dark, veinous clouds weaving their way through a massive crimson oval. The JunoCam imager aboard NASA’s Juno mission snapped pics of the most iconic feature of the solar system’s largest planetary inhabitant during its Monday (July 10th) flyby.

The images of the Great Red Spot were downlinked from the spacecraft’s memory on Tuesday and placed on the mission’s JunoCam website Wednesday morning.

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Juno mission completed a close flyby of Jupiter and its Great Red Spot on July 10th, during its sixth science orbit.

All of Juno’s science instruments and the spacecraft’s JunoCam were operating during the flyby, collecting data that are now being returned to Earth. Juno’s next close flyby of Jupiter will occur on September 1st, 2017.

Raw images from the spacecraft’s latest flyby will be posted in coming days.

Dodging the Roadkill: Pop’s Travel Center

 

Dodging the Roadkill - A Biker's JourneyLacon, AL – Along Interstate 65, between Huntsville and Birmingham Alabama, just off exit 318, sits a welcome site.  Pop’s Travel Center.  It’s the only business at this exit and it’s well worth the visit.

I discovered this place quite by accident.  

While riding my Harley back home to Tennessee last year, I was getting “drowsy” and had a bit of an appetite, so the next exit, 318, I pulled off to take a break.

I was greeted by a Stuckeys and a family restaurant.  Having grown up visiting Stuckeys when we traveled,  it was a welcome site.

NASA’s Juno Spacecraft to take close up look at Jupiter’s Great Red Spot

 

Written by DC Agle / Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Just days after celebrating its first anniversary in Jupiter orbit, NASA’s Juno spacecraft will fly directly over Jupiter’s Great Red Spot, the gas giant’s iconic, 10,000-mile-wide (16,000-kilometer-wide) storm. This will be humanity’s first up-close and personal view of the gigantic feature — a storm monitored since 1830 and possibly existing for more than 350 years.

“Jupiter’s mysterious Great Red Spot is probably the best-known feature of Jupiter,” said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. “This monumental storm has raged on the solar system’s biggest planet for centuries. Now, Juno and her cloud-penetrating science instruments will dive in to see how deep the roots of this storm go, and help us understand how this giant storm works and what makes it so special.”

Earth’s most powerful telescopes enhance NASA’s Juno Spacecraft’s Jupiter Flyby

 

Written by Laurie Cantillo / Dwayne Brown
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Telescopes in Hawaii have obtained new images of Jupiter and its Great Red Spot, which will assist the first-ever close-up study of the Great Red Spot, planned for July 10th. On that date, NASA’s Juno spacecraft will fly directly over the giant planet’s most famous feature at an altitude of only about 5,600 miles (9,000 kilometers).

Throughout the Juno mission, numerous observations of Jupiter by Earth-based telescopes have been acquired in coordination with the mission, to help Juno investigate the giant planet’s atmosphere.

This composite, false-color infrared image of Jupiter reveals haze particles over a range of altitudes, as seen in reflected sunlight. It was taken using the Gemini North telescope in Hawaii on May 18, 2017, in collaboration with observations of Jupiter by NASA's Juno mission.

NASA’s Chandra X-ray Observatory photo shows merger of Two Galaxies

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – What would happen if you took two galaxies and mixed them together over millions of years? A new image including data from NASA’s Chandra X-ray Observatory reveals the cosmic culinary outcome.

Arp 299 is a system located about 140 million light years from Earth. It contains two galaxies that are merging, creating a partially blended mix of stars from each galaxy in the process.

However, this stellar mix is not the only ingredient. New data from Chandra reveals 25 bright X-ray sources sprinkled throughout the Arp 299 concoction.

NASA reports LIGO detects Third Gravitational Wave

 

Written by Molly Porter
NASA’s Marshall Space Flight Center

NASA - National Aeronautics and Space AdministrationHuntsville, AL – About 3 billion years ago, a pair of orbiting black holes collided to form a single object with 49 times the mass of our sun. The event unleashed powerful gravitational waves—ripples in the very fabric of space and time—that reached Earth seconds before 4:12am CST on January 4th, 2017.

That’s when they were detected by the ground-based twin Laser Interferometer Gravitational-Wave Observatory (LIGO) facilities in Hanford, Washington, and Livingston, Louisiana.

The event, known as GW170104, after the date, is the third detection of gravitational waves by LIGO. Located at a distance of about 3 billion light-years, the coalesced black hole is twice as far away as both of the two mergers previously detected.

This artist illustration shows two black holes (black spheres) of nearly equal mass as they spiral together and merge. (NASA)

NASA’s Juno Spacecraft provides fascinating discoveries about Jupiter

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Early science results from NASA’s Juno mission to Jupiter portray the largest planet in our solar system as a complex, gigantic, turbulent world, with Earth-sized polar cyclones, plunging storm systems that travel deep into the heart of the gas giant, and a mammoth, lumpy magnetic field that may indicate it was generated closer to the planet’s surface than previously thought.

“We are excited to share these early discoveries, which help us better understand what makes Jupiter so fascinating,” said Diane Brown, Juno program executive at NASA Headquarters in Washington. “It was a long trip to get to Jupiter, but these first results already demonstrate it was well worth the journey.”

NASA's Juno spacecraft carries an instrument called the Microwave Radiometer, which examines Jupiter's atmosphere beneath the planet's cloud tops. (NASA/JPL-Caltech/SwRI)
