A team of astronomers combining radio data from the Green Bank Telescope, West Virginia, and data from the radar transmitter at the National Science Foundation's Arecibo Observatory, Puerto Rico, have compiled a stunning new view of Venus. Often described as Earth's twin due to its similar proportions, capturing high quality images of the inhospitable planet has traditionally been a challenging prospect thanks to extreme atmospheric conditions. However, by combining observations from the instruments to create a more complete picture of Venus, astronomers can begin to observe how this enigmatic celestial object evolves over time.  Read More

DSCOVR, the NOAA's Earth observation and space weather satellite, being readied for launch...

Sunday's delayed launch means that NOAA's Deep Space Climate Observatory (DSCOVR) will wait at least a day before it can take up its job of helping warn of potentially damaging solar flares. If Monday's rescheduled liftoff goes as planned, the unmanned spacecraft will be on its way to a point between the Earth and the Sun, where it will act as a space weather observatory and early warning station.  Read More

When you're hunting for exoplanets many light years away, the complications posed by the Earth's atmosphere can make the search incredibly difficult for ground-based telescopes. That's why space-based telescopes, such as Hubble, Spitzer and Kepler, are generally employed for the job. But now for the first time, astronomers have detected the transit of a super-Earth in front of a nearby Sun-like star, which could see ground-based telescopes more widely used in categorizing the growing number of exoplanets expected to be discovered in the next few years.  Read More

During its nominal five-year mission, Gaia will scout the skies cataloging a billion stars...

After a 20-year search, astronomers have uncovered a grand total of 1,900 planets residing outside of the Solar System. According to a new Princeton study, the Gaia space observatory launched by the European Space Agency (ESA) could help that figure grow by a factor of ten by the end of the decade, eventually reaching 70,000 planets after 10 years of scouting.  Read More

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

The ANU SkyMapper telescope at the Siding Spring Observatory has discovered the oldest kno...

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
