The spring has come, and the onset of mild weather in most of the northern hemisphere brings forth a hunger for new celestial objects to observe. Following on from our top picks for winter stargazing, here's our selection of the best targets for spring viewing.  Read More

The ALMA telescope has been used to pinpoint the locations of early star-forming galaxies ...

Astronomers have used the Atacama Large Millimeter/submillimter Array (ALMA) telescope to more accurately map dusty star-forming galaxies in the early Universe. The new telescope is significantly more powerful than other similar devices, and in just a few hours, using less than a quarter of its full capacity, was able to double the number of confirmed observations of this type.  Read More

SOFIA's FORCAST telescope was used to collect infrared readings from protostar G35.20-0.74

Observations made by NASA's airborne Stratospheric Observatory for Infrared Astronomy (SOFIA) have led to a development in our understanding of the formation of massive stars. By studying the star G35, the team found that the formation process was more akin to that of smaller stars than was previously thought.  Read More

The Thirty-Meter Telescope (TMT) (Image: Courtesy TMT Observatory Corporation)

The world’s largest optical telescope got the go ahead last Friday when the Hawaiian Board of Land and Natural Resources (BLNR) granted a building and operating permit for the Thirty Meter Telescope (TMT) to be sited on a plateau of Mauna Kea on the island of Hawaii. The next-generation telescope, which uses a 30-meter (98 ft) segmented mirror promises to capture images from the near-ultraviolet to the mid-infrared wavelengths with unprecedented clarity.  Read More

Project 1640 image of the four exoplanets orbiting HR 8977. The image has been enhanced fo...

While the number of exoplanets so far identified is steadily marching towards the 1000 mark, fewer than twenty have been discovered in the course of direct observation by astronomical telescopes. Four of them (HR 8977 b,c,d,and e) circle an unprepossessing A5 star called HR 8977, which lies about 130 light-years distant from Earth. Thanks to the little-known astrophysics research arm of the American Museum of Natural History (AMNH), we now have the ability to examine the makeup of their atmospheres by taking simultaneous spectrographs of all four planets.  Read More

The ESA's Planck space telescope has revealed a detailed image showing the 'afterglow' of ...

A new image acquired by the European Space Agency's (ESA) Planck space telescope provides an unprecedented view of the oldest light in the Universe. The image represents the most detailed mapping of cosmic microwave background (CMB) ever created and both solidifies and questions our current understanding of the Universe.  Read More

Astronomers have used the Herschel space observatory to detect a group of fledgling stars ...

Observations made by the Herschel space observatory have revealed 15 protostars in the constellation Orion, the biggest star formation area near our own solar system. The observatory was the first telescope to reveal the grouping, with previous studies of the area missing the stars which are thought to be some of the youngest and coldest in the constellation. The discovery is a significant step in furthering our understanding of how stars form.  Read More

Even before the Atacama Large Millimeter/submillimeter Array (ALMA) was inaugurated this week, it was already rewriting history with its observations showing that a stellar baby boom took place much earlier than previously thought. But the pre-inauguration announcement isn’t a reflection that the ALMA team didn’t get to enjoy the official ceremony – like the first images released in 2011, the observations were taken while ALMA was still under construction.  Read More

A look at some of the ESO's best images of 2013

Despite being only a couple of months into the year, the various telescopes of the European Southern Observatory (ESO) have already provided some truly breathtaking sights. From dusty stellar nurseries to giant star clusters, here's a look at the best ESO images of 2013 so far.  Read More

The first comet discovered this year, Comet C/2013 A1, is currently projected to pass within about 23,000 miles (37,000 km) of the surface of Mars late in 2014. While this event in itself promises spectacular views for astronomers, the uncertainty of the comet's orbit includes a significant chance of an impact on Mars. If this happens, the impact would be hundreds of times more powerful than the asteroid impact that wiped out the dinosaurs on Earth.  Read More
