• Dec. 27, 2017 - Permanently in residence at dwarf planet Ceres, Dawn is now preparing to add some finishing touches to its many images revealing its masterpiece of otherworldly beauty. Dawn will enter an eliptical orbit in mid-2018 that will take Dawn even closer, perhaps below 30 miles (50 kilometers). Summary from Marc Rayman's Blog, Dawn Mission Director and Chief Engineer Marc Rayman's Blog "Dear Long Disdawnce Travelers".
• Dec. 11, 2017 - The IAU stellar name catalogue now contains 313 approved star names. The new 86 star names are from Chinese, Coptic, Hindu, Mayan, Polynesian, South African and Aboriginal cultures—honoring the indigenous starlore of these cultures. iau1707 — Press Release
For 26 years, the NASA/ESA Hubble Space Telescope has been expanding our cosmic horizons. In capturing an astronomical number of images, Hubble has revealed and shared the beauty, wonder, and complexity of the Universe. On February 1, 2017, a new exhibition called "Our Place in Space" openned in Venice, Italy. It presents a breathtaking visual journey, through our Solar System and out to the edge of the known Universe, alongside Hubble-inspired works by contemporary Italian artists....
After being on display in Venice the exhibition will be shown in the medieval town of Chiavenna, Italy, from May 13 to August 20, 2017. Afterwards it will be on display in Garching, Germany, in the ESO Supernova Planetarium & Visitor Centre, from the spring of 2018. Further stops in other European countries, the USA and even Australia are being considered. Entrance to the exhibition is free of charge on all occasions. Hubble: Our Place in Space
The James Webb Space Telescope (sometimes called JWST or Webb) will be a large infrared telescope with a 6.5-meter primary mirror. The telescope will be launched on an Ariane 5 rocket from French Guiana in October of 2018. JWST will be the premier observatory of the next decade, serving thousands of astronomers worldwide....
JWST was formerly known as the "Next Generation Space Telescope" (NGST); it was renamed in Sept. 2002 after a former NASA administrator, James Webb. JWST is an international collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). The NASA Goddard Space Flight Center is managing the development effort. The main industrial partner is Northrop Grumman; the Space Telescope Science Institute will operate JWST after launch....
"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 Aug. 27 when the spacecraft came about 2,500 miles (4,200 kilometers) above Jupiter’s swirling clouds. The download of six megabytes of data collected during the six-hour transit, from above Jupiter’s north pole to below its south pole, took one-and-a-half days. While analysis of this first data collection is ongoing, some unique discoveries have already made themselves visible...." (NASA)

ESA's Gaia Mission (billion-star surveyor)
"Gaia is an ambitious mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy. Gaia will provide unprecedented positional and radial velocity measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group. This amounts to about 1 per cent of the Galactic stellar population. The mission's ultimate goal is to create the largest, most precise 3D map of our Galaxy ever made." (ESA)
Mission Conception: 2000
Payload launched: Dec 19, 2013
Calibration and testing phase, First test Images: Early 2014
Science phase begins: Mid 2014 (five year operational phase)
First catalogue release, planned for summer 2016
03 July 2015 - "This image, based on housekeeping data from ESA's Gaia satellite, is no ordinary depiction of the heavens. While the image portrays the outline of our Galaxy, the Milky Way, and of its neighbouring Magellanic Clouds, it was obtained in a rather unusual way." How this image was made.
ALMA - In Search for our Cosmic Origins
"The Atacama Large Millimeter/submillimeter Array (ALMA), an international partnership of the European Organisation for Astronomical Research in the Southern Hemisphere (ESO), the U.S. National Science Foundation (NSF) and the National Institutes of Natural Sciences (NINS) of Japan in cooperation with the Republic of Chile, is the largest astronomical project in existence. ALMA is a single telescope of revolutionary design, composed initially of 66 high precision antennas located on the Chajnantor plateau, 5000 meters altitude in northern Chile." (ALMA)

New Asteroid Families Discovered
May 29, 2013
Astronomers using data from NASA's Wide-field Infrared Survey Explorer (WISE) have identified 28 new families of asteroids. The findings are a critical step in understanding the origins of asteroid families, and the collisions thought to have created these rocky clans.
"We're separating zebras from the gazelles," said Joseph Masiero of NASA's Jet Propulsion Laboratory in Pasadena, Calif., who is lead author of a report on the new study that appears in the Astrophysical Journal. "Before, asteroid family members were harder to tell apart because they were traveling in nearby packs. But now we have a better idea of which asteroid belongs to which family."
Saturn's Super-sized Vortex
Saturn's Hex, nesting upon Saturn's North Pole, is large enough to fit two Earth's inside. The Hurricane-like Super Storm Vortex lies fixed within the Hex whirling about Saturn's north pole. The eye alone of this relentless vortex stretches about 2000 kilometers (1250 miles) across, with vaporous clouds whipping around the outer edge of the storm at about 150 meters per second (330 miles per hour).

Saturn's Super Storm
May, 2011 post
"NASA's Cassini spacecraft and a European Southern Observatory ground-based telescope are tracking the growth of a giant early-spring storm in Saturn's northern hemisphere so powerful that it stretches around the entire planet. The rare storm has been wreaking havoc for months and shooting plumes of gas high into the planet's atmosphere...."

Mars Express and Phobos
To say Phobos, a moon of Mars, is hollow is a bit of an over statement, however it has been concluded by Mars Express that the interior of Phobos likely contains large voids. Mars Express passes by Phobos about every five months providing opportunity for close-up analysis. The next flybys will occur in August 2010 and January 2011. More at the The ESA Mars Express Blog.
