The Sloan Digital Sky Survey (SDSS) is little known to the public, but represents one of the most-challenging efforts in observational cosmology ever attempted. The most recent phase, SDSS-III, began in 2008 and includes the Baryon Oscillation Spectroscopic Survey (BOSS), a part of SDSS-III aimed at mapping the cosmos. Its goal is to map the physical locations of all major galaxies back to seven billion years ago, and bright quasars back to 12 billion years ago – two billion years after the Big Bang. This is being done so we can gain a better understanding of dark matter and energy, and hopefully encounter a few surprises.  Read More

The International Lunar Observatory Association is to send a tested telescope on board Moo...

The International Lunar Observatory Association (ILOA) is being backed by Google Lunar X Prize contestant Moon Express in placing a small telescope on the Moon's surface to test and troubleshoot operating protocols for a fully loaded remote telescope. Last week, the ILO-X, the first ILOA telescope that will be sent to the Moon, was remotely tested by ILOA and Moon Express on the summit of Mauna Kea, and passed with flying colors. Later ILOA/Moon Express missions will include landing considerably larger telescopes at strategic locations on the lunar surface.  Read More

NASA researchers are trying a 'scotch tape' design to build larger, more affordable X-ray ...

A team led by NASA's Maxim Markevitch is investigating the possibility of building bigger X-ray telescope mirrors – up to thirty times as large as today's – using a plastic tape coated with a reflective material and then, just like a roll of Scotch tape, tightly rolled on itself. By studying cosmic rays and distant galaxy clusters, such large and significantly cheaper mirrors would allow us to learn more about the birth and evolution of the universe.  Read More

The distance from Earth to the Sentinel space telescope will vary between 30-170 million m...

California-based non-profit B612 Foundation has announced its intention to place an asteroid-hunting infrared telescope into orbit around the Sun. Named Sentinel, the ambitious endeavor is to be the world's first privately funded deep space mission and will aim to map up to 90 percent of all asteroids larger than 140 meters (459 ft) in Earth’s region of the solar system. In addition to these sizable asteroids, Sentinel will further provide data on a number of smaller asteroids, down to a size of approximately 30 meters (98 ft) in diameter.  Read More

Upon completion, the E-ELT is expected to be the largest optical telescope in the world

The European Southern Observatory (ESO) council met on Monday in Garching, Germany and approved the European Extremely Large Telescope (E-ELT) program, pending the confirmation of ad referendum votes from the authorities of four member states before the next council meeting. Assuming all goes according to plan, the E-ELT is expected to begin operation early in the next decade.  Read More

The Square Kilometer Array (SKA) will be shared between Australia and South Africa (Image:...

After a tense few months that has had many in Australia and South Africa anxiously awaiting word on whether their particular site will be chosen to host the world’s largest and most sensitive radio telescope, the Square Kilometer Array (SKA) Organisation has finally made its decision. And it’s good news for both bids – or bad news, if you’re the glass half empty sort - with the organization opting for a dual-site solution that will see the SKA telescope shared between Australia and South Africa.  Read More

A cut-away view of the LSST camera, with a person for scale

Although the pixel count for consumer cameras continues to rise, they will all pale in comparison to the 3,200-megapixel Large Synoptic Survey Telescope (LSST) camera. Although the enormous astronomical camera has yet to be built, last week the U.S. Department of Energy gave its approval for the project to proceed to the next phase of development. This means that a detailed engineering design can begin, along with a production schedule and budget. If everything goes according to plan, construction on what will be the world’s largest digital camera should begin in 2014.  Read More

The NIRCam that has passed its testing at Lockheed Martin and is being readied for shipmen...

Assembly has been completed on the Near Infrared Camera (NIRCam) that will be the primary imager on NASA’s James Webb Space Telescope (JWST) and will also act as the telescope’s wavefront sensor to allow for control of its primary mirror. NIRCam covers the infrared wavelength range of 0.6 (the edge of visible) to 5 microns (near infrared) and its focal plane assemblies (FPA) consist of 40 million pixels and are designed to operate at 35 degrees Kelvin (-396°F/-238°C).  Read More

IBM and ASTRON (the Netherlands Institute for Radio Astronomy) are working to develop tech...

When completed in 2024, the Square Kilometre Array (SKA) will be the largest, most sensitive radio telescope ever created. It will consist of 3,000 individual ground-based dish antennas, linked to act as one big telescope – an arrangement known as an interferometer. While their combined total surface area will be about one square kilometer (0.39 sq mile), they will be spread out across a geographical area approximately 3,000 kilometers (1,864 miles) in width. They will be gathering about one exabyte of astronomical data per day, which is twice the amount of data that is handled by the World Wide Web on a daily basis. Today, IBM announced that it has partnered with ASTRON (the Netherlands Institute for Radio Astronomy), in an effort to develop computer systems that will be able read, analyze and store all of that data, and do so in an energy-efficient manner.  Read More

Astronomers using data from NASA's Kepler mission have discovered the tiniest solar system found so far. The system consists of a single red dwarf star, known as KOI-961 and three planets which are 0.78, 0.73 and 0.57 times the radius of Earth. The planets are thought to be rocky - like Earth - but orbit much closer to their star making them too hot to be habitable.  Read More
