Saturn's rings affect the planet's ionosphere

Tue, 12/12/2017 - 13:17
Data collected by the Cassini spacecraft, before it was deliberately crashed into Saturn's atmosphere in September 2017, show that the planet's illustrious rings are casting a shadow in ionized particles over the planet. Cassini has transmitted a hoard of valuable data from Saturn since it arrived at the planet in 2004.   Language English

Great Red Spot's roots

Tue, 12/12/2017 - 12:13
Data collected by NASA's Juno spacecraft during its first pass over Jupiter's Great Red Spot in July 2017 indicate that this iconic feature penetrates well below the clouds. Other revelations from the mission include that Jupiter has two previously uncharted radiation zones. The findings were announced Monday at the annual American Geophysical Union meeting in New Orleans. Language English

Happy Birthday COSMO-SkyMed #10

Thu, 12/07/2017 - 17:48
The present and the future of the COSMO-SkyMed satellite system, which over the ten years since the first satellite was launched, has changed the way the Earth is observed, ensuring essential information for our security and for understanding our Planet. This was discussed at MAXXI in Rome by the Italian Minister of Education, University, and Research, Valeria Fedeli, the Secretary General of Defence and National Armaments Director, Lt. Gen.

Jupiter in striking shades of blue

Fri, 12/01/2017 - 13:08
The Juno spacecraft captured this image when the spacecraft was only 18,906 kilometers from the tops of Jupiter’s clouds — that’s roughly as far as the distance between New York City and Perth, Australia.   The color-enhanced image, which captures a cloud system in Jupiter’s northern hemisphere, was taken on Oct. 24, 2017 when Juno was at a latitude of 57.57 degrees (nearly three-fifths of the way from Jupiter’s equator to its north pole) and performing its ninth close flyby of the gas giant planet. The spatial scale in this image is 2.5 kilometers/pixel.   Language English

Saturn, the beginning and the end

Tue, 11/28/2017 - 12:31
These two images illustrate just how far Cassini traveled to get to Saturn. On the left is one of the earliest images Cassini took of the ringed planet, captured during the long voyage from the inner solar system. On the right is one of Cassini's final images of Saturn, showing the site where the spacecraft would enter the atmosphere on the following day.   Language English

The abundance of positrons: pulsars don't seem to be the origin

Wed, 11/22/2017 - 14:57
It is called the High-Altitude Water Cherenkov (HAWC) and it is an observatory with a high level of gamma rays located in Mexico. The international team that built it and runs it has managed to capture, for the first time, a broad picture of very high energy gamma emissions coming from the sky, and in particular identifying the contribution coming from two pulsars close to the Earth, which are two fast-spinning neutron stars, including Geminga. Language English

Cassini: a farewell to Saturn

Wed, 11/22/2017 - 12:35
In a fitting farewell to the planet that had been its home for over 13 years, the Cassini spacecraft took one last, lingering look at Saturn and its splendid rings during the final leg of its journey and snapped a series of images that has been assembled into a new mosaic. Cassini’s wide-angle camera acquired 42 red, green and blue images, covering the planet and its main rings from one end to the other, on Sept. 13, 2017. Language English

JUICE Missione, radar sounder chosen

Wed, 11/15/2017 - 15:17
JUICE (JUpiter ICy moons Explorer) mission, part of the European Space Agency’s “2015-25 Cosmic Vision” program has been conceived to study Jupiter’s icy moons.  Language English

String of pearls on Jupiter’s surface

Fri, 11/10/2017 - 13:15
The color-enhanced view captures one of the white ovals in the “String of Pearls,” one of eight massive rotating storms at 40 degrees south latitude on the gas giant planet.   The image was taken on Oct. 24, 2017 as Juno performed its ninth close flyby of Jupiter. At the time the image was taken, the spacecraft was 33,115 kilometers from the tops of the clouds of the planet at a latitude of minus 52.96 degrees. The spatial scale in this image is 22.3 kilometers/pixel.   Language English

What's hiding into the core of Enceladus

Tue, 11/07/2017 - 16:57
Heat from friction could power hydrothermal activity on Saturn's moon Enceladus for billions of years if the moon has a highly porous core, according to a new modeling study by European and U.S. researchers working on NASA's Cassini mission.   The study, published today in the journal Nature Astronomy, helps resolve a question scientists have grappled with for a decade:  Where does the energy to power the extraordinary geologic activity on Enceladus come from? Language English

Cosmic rays in the eye of CALET

Mon, 11/06/2017 - 13:27
The CALET Cosmic Ray experiment, has successfully carried out the high-precision measurement of cosmic-ray electron spectrum up to 3 tera electron volts (TeV) by using the CALorimetric Electron Telescope (CALET) on the Japanese Experimental Module, the Exposed Facility on the International Space Station (ISS). This experiment is the first to make direct measurements of such high energy electrons in space. Language English

ISNCC Symposium

Fri, 11/03/2017 - 14:58
The International Symposium on Networks, Computers and Communications (ISNCC) will be held in Rome, from 19 to 21 June 2018, under the patronage of the Italian Space Agency, the NITEL Consortium and the APRE Agency.  Enrico Russo, ASI Technical Director has been appointed as ISNCC’s Honorary General Chair.  Language English

Juno aces eighth science pass of Jupiter

Fri, 11/03/2017 - 12:48
Data returned Tuesday, Oct. 31, indicate that NASA’s Juno spacecraft successfully completed its eighth science flyby over Jupiter's mysterious cloud tops on Tuesday, Oct. 24. The confirmation was delayed by several days due to solar conjunction at Jupiter, which affected communications during the days prior to and after the flyby. Language English

Saturn, light on the north pole

Tue, 10/31/2017 - 10:43
Reflected sunlight is the source of the illumination for visible wavelength images such as the one above.  However, at longer infrared wavelengths, direct thermal emission from objects dominates over reflected sunlight.  This enabled instruments that can detect infrared radiation to observe the pole even in the dark days of winter when Cassini first arrived at Saturn and Saturn's northern hemisphere was shrouded in shadow.  Language English

Dawn finds possible ocean remnants at Ceres

Fri, 10/27/2017 - 14:53
Minerals containing water are widespread on Ceres, suggesting the dwarf planet may have had a global ocean in the past. What became of that ocean? Could Ceres still have liquid today? Two new studies from NASA's Dawn mission shed light on these questions. Language English

From Cassini's collection

Tue, 10/24/2017 - 15:00
Saturn's graceful lanes of orbiting ice -- its iconic rings -- wind their way around the planet to pass beyond the horizon in this view from  Cassini spacecraft.  And diminutive Pandora, scarcely larger than a pixel here, can be seen orbiting just beyond the F ring in this image.   Language English

Dawn mission extended

Fri, 10/20/2017 - 15:57
NASA has authorized a second extension of the Dawn mission at Ceres, the largest object in the asteroid belt between Mars and Jupiter. During this extension, the spacecraft will descend to lower altitudes than ever before at the dwarf planet, which it has been orbiting since March 2015. The spacecraft will continue at Ceres for the remainder of its science investigation and will remain in a stable orbit indefinitely after its hydrazine fuel runs out. Language English

Cassini spacecraft ended its journey on Sept. 15 with an intentional plunge into the atmosphere of Saturn, but analysis continues on the mountain of data the spacecraft sent during its long life. Some of the Cassini team's freshest insights were presented during a news conference yesterday at the American Astronomical Society Division for Planetary Science meeting in Provo, Utah. Among the findings being shared: Language English
