Titan and Saturn. Image credit: NASA/JPL-Caltech/Space Science Institute .

Saturn's largest moon, Titan, looks small here, pictured to the right of the gas giant in this Cassini spacecraft view.

Titan (3,200 miles, or 5,150 kilometers across) is in the upper right. Saturn's rings appear across the top of the image, and they cast a series of shadows onto the planet across the middle of the image.

The moon Prometheus (53 miles, or 86 kilometers across) appears as a tiny white speck above the rings in the far upper right of the image. The shadow cast by Prometheus can be seen as a small black speck on the planet on the far left of the image, between the shadows cast by the main rings and the thin F ring. The shadow of the moon Pandora also can be seen on the planet south of the shadows of all the rings, below the center of the image towards the right side of the planet. Pandora is not shown here.

This view looks toward the southern, unilluminated side of the rings from about 1 degree below the ringplane.

The image was taken with the Cassini spacecraft wide-angle camera on Jan. 5, 2012 using a spectral filter sensitive to wavelengths of near-infrared light centered at 752 nanometers. The view was acquired at a distance of approximately 426,000 miles (685,000 kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 20 degrees. Image scale is 23 miles (37 kilometers) per pixel on Saturn. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

Astronomers using NASA's Chandra X-ray Observatory have clocked the fastest wind yet discovered blowing off a disk around a stellar-mass black hole. This result has important implications for understanding how this type of black hole behaves.

The record-breaking wind is moving about 20 million mph, or about 3 percent of the speed of light. This is nearly 10 times faster than had ever been seen from a stellar-mass black hole.

Stellar-mass black holes are born when extremely massive stars collapse. They typically weigh between five and 10 times the mass of the sun. The stellar-mass black hole powering this super wind is known as IGR J17091-3624, or IGR J17091 for short. (read more)

Spitzer finds solid Buckyballs in Space

Source: NASA Spitzer


NASA's Spitzer Space Telescope has detected little spheres of
carbon, called buckyballs, in the Small Magellanic Cloud.
Image credits: NASA/JPL-Caltech.

Astronomers using data from NASA's Spitzer Space Telescope have, for the first time, discovered buckyballs in a solid form in space. Prior to this discovery, the microscopic carbon spheres had been found only in gas form.

Formally named buckminsterfullerene, buckyballs are named after their resemblance to the late architect Buckminster Fuller's geodesic domes. They are made up of 60 carbon molecules arranged into a hollow sphere, like a soccer ball. Their unusual structure makes them ideal candidates for electrical and chemical applications on Earth, including superconducting materials, medicines, water purification and armor.

In the latest discovery, scientists using Spitzer detected tiny specks of matter, or particles, consisting of stacked  buckyballs. They found them around a pair of stars called "XX Ophiuchi," 6,500 light-years from Earth. (read more)

Hypernuclei - The core of strange matter discovered

Source: PhysOrg

Physicists in Italy have discovered the first evidence of a rare nucleus that doesn’t exist in nature and lives for just 10-10 seconds before decaying. It’s a type of hypernucleus that, like all nuclei, contains an assortment of neutrons and protons. But unlike ordinary nuclei, hypernuclei also contain at least one hyperon, a particle that consists of three quarks, including at least one strange quark. Hypernuclei are thought to form the core of strange matter that may exist in distant parts of the universe, and could also allow physicists to probe the inside of the nucleus. (read more)

Titan Flyby: Back to the South

Source:Cassini Solstice Mission


Image credit: NASA/JPL

Tomorrow Cassini goes back to Titan to make the T-82 flyby close to Titan's south pole.

During this close Titan flyby, the composite infrared spectrometer (CIRS) performs a wide variety of observations, including limb sounding, and mapping of surface and atmospheric temperatures. Far-infrared limb sounding near closest approach reaches the most northerly latitude of the Solstice Mission. (75 degrees North) until 2015, providing insights into the transition of the northern polar circulation from spring to summer, and includes a search for possible condensates. The Visible and Infrared Mapping Spectrometer (VIMS) rides-along to detect clouds to monitor climatic changes after the equinox.T-82 is a dusk sector equatorial flyby across Titan's magnetic tail. Similar in geometry, but at a lower altitude (2,363 miles, or 3,803 kilometers) than T-78, Cassini will be able to provide a better characterization of the magnetotail by providing samples at different radial distances from the moon at a fixed local time.

A new image from the APEX (Atacama Pathfinder Experiment) telescope in Chile shows a sinuous filament of cosmic dust more than ten light-years long. In it, newborn stars are hidden, and dense clouds of gas are on the verge of collapsing to form yet more stars. It is one of the regions of star formation closest to us. The cosmic dust grains are so cold that observations at wavelengths of around one millimetre, such as these made with the LABOCA camera on APEX, are needed to detect their faint glow.(read more)

The Odysseus Project - A new contest for schools

Odysseus is a European project, co-founded by the European Commission under the 7th Framework Programme, in the Space area for ” Studies and events in support of European Space Policy”.

Space exploration advances our knowledge, allows us to understand and protect our planet better and provides the opportunity to discover the answers to fundamental questions about the history of Earth, the origin of life, the Solar System and the Universe. In other words space exploration is pushing forward the limits of our knowledge and is engaging and inspiring the public in the “New Frontier”. The Odysseus project aims exactly at engaging and inspiring the European youth in the “New Frontier”, by implementing a pan-European Scientific Contest for young people on Space exploration themes, combining creativity, intelligence and innovation.

The project, which started on 1st November 2011 and will last for 18 months, aspires to integrate ongoing educational activities on science in a pan-European perspective, providing the opportunity for young pupils to compete with their peers from different European countries. This action is also enhancing the concept of multinational cooperation, an element necessary in space exploration field. All participants have to be between 14 to 18 years old and in order to submit their entry will have to create a collaborative team, which would design and demonstrate an innovative project in one of the contest’s themes.

The total budget of Odysseus project is € 335,000, with approximately € 300,000 financing by the European Commission.
