In preparation for the Square Kilometer Array (SKA) radio telescope project set to start construction in 2018, the CSIRO’s recently unveiled Australia SKA Pathfinder (ASKAP) radio telescope array has been used to demonstrate and prove the technology involved. With the images it has captured so far, it has also shown its ability to operate as a fully-fledged radio telescope in its own right.  Read More

NASA scientists are eager to get to grips with a new toy for observing the heavens, the Echelon-Cross-Echelle Spectrograph (EXES). Mounted on a heavily-customized Boeing 747, the spectrograph has undergone two successful test flights and when declared operational, will comb the sky for infrared frequency light aboard the largest flying telescope ever constructed.  Read More

With the use of seven telescopes spread across South America, observers have confirmed the unlikely discovery of a double ring surrounding the minor planet Chariklo, which holds orbit between Saturn and Uranus. Previously rings have only been found around giant planets, the most dramatic of which, Saturn, shines easily visible to the naked eye in the night sky.  Read More

The European Space Observatory's Very Large Telescope (VLT) has spotted a massive yellow star with a diameter of more than 1,300 times the size of the Sun. The star is also a part of a binary system, with a companion star orbiting so close that it is actually in physical contact with the giant.  Read More

A team of astronomers at The Australian National University (ANU) working on a five-year project to produce the first comprehensive digital survey of the southern sky has discovered the oldest known star in the Universe. Just a 6,000 light year astronomical hop, skip and jump from Earth, the ancient star formed shortly after the Big Bang 13.7 billion years ago.  Read More

Online observatory Slooh has streamed live pictures of NASA’s Juno space probe flyby. The feed from the robotic half-meter telescope in the Canary islands gave visitors a ringside seat as the probe passed within 347 mi (559 km) of Earth in a slingshot maneuver designed to take it all the way to Jupiter.  Read More

The last antenna arrives at the ALMA observatory in Chile (Image: ESO)

The last 12 meter (40 ft) antenna has arrived at the Atacama Large Millimeter/submillimeter Array (ALMA), pushing the project closer to its full operational potential. The final antenna was supplied by the European side of the venture, and completes the 66 dish array stretching across the Chajnantor Plateau in Chile's Atacama Desert. The telescope, which was inaugurated in March 2013, has already made a number of significant discoveries despite its incomplete nature.  Read More

Korean architectural studio GDS Architects has received the green light for its award winning 450 meter high Tower Infinity design. To be built near the Incheon International Airport just outside of Seoul, Tower Infinity will become the "world's first invisible tower" and third highest observation deck.  Read More

An international team of scientists using one of the pair of 10-meter telescopes at the W.M. Keck Observatory on the summit of Mauna Kea on the island of Hawaii has now shown that the early moments of our Universe closely followed the theoretical model for the genesis of the elements. Improved observational and modeling methods show that the elemental composition of the post-Big Bang universe agrees with the predictions of that model, eliminating what was thought to be a substantial discrepancy between theory and observation.  Read More

Three years ago the very first images from the Solar Dynamics Observatory (SDO) were beamed back to earth. Since then, NASA’s SDO has effectively had continuous coverage of the Sun’s rise towards solar maximum, the period of the most intense solar activity in the 11 year solar cycle. NASA has now provided a fascinating snapshot of this ongoing research in the form of a time-lapse video that squeezes three years of solar activity into three minutes of footage.  Read More
