The HSC image shows M31 in stunning detail (Image: HSC Project/NAOJ)

The Andromeda galaxy is one of the most commonly studied objects in the sky. It's just 2.5 million light years from Earth, is visible to the naked eye on a moonless night and has been imaged countless times. Japan's Subaru Telescope's Hyper Suprime-Cam (HSC) has provided the latest snap of the popular object, showing our neighboring galaxy in a spectacular new light.  Read More

The right eyepieces can help you get more out of your starter telescope (Image: Shuttersto...

OK, so you've put your hands on a decent starter telescope. We're not talking about one of the cheap 50 mm aperture "department store" scopes, but a good quality 4 to 6-inch aperture scope. You've seen this and that in the night skies, and now you want a bit of an upgrade. Here's Gizmag's guide to getting there as easily as possible, without having to buy a new telescope.  Read More

The Large Magellanic Cloud as taken by the Swift satellite's Ultraviolet/Optical telescope...

Data from NASA's Swift satellite has been used to create the highest-ever resolution images of our two nearest galaxies, the Magellanic Clouds. The detailed ultraviolet light surveys measure 160 and 55 megapixels, and cumulatively show some 1.25 million ultraviolet sources.  Read More

Massive galaxy LRG 3-757 forms a gravitational lens for a second galaxy (blue ring) at a d...

Gravitational lenses, which are massive galaxies or galaxy clusters that act as a magnifying glass by bending light passing them, are one of the Universe's golden gifts to astronomers. To help unlock the mysteries that might lie behind these untapped celestial resources, Zooniverse, a program of the Citizens Science Alliance, has begun the Space Warps project. It allows citizen scientists to put their skills at pattern/image recognition to use, toward finding these fugitive gravitational lenses.  Read More

The International Space Apps Challenge asked teams to solve problems for both Earth and sp...

Given a set of problems related to space exploration and a 48-hour deadline, 9,000 people in 80 locations around the world created over 600 solutions. The International Space Apps Challenge, sponsored by NASA and other international space agencies, offered up massive amounts of data and other resources to teams of hackers who responded with creative solutions. The public now has the chance to view these solutions online and vote for their favorites on each project's official page. Gizmag set out to find the best projects related to data visualization and education, space exploration and satellite inventiveness, green technology, and remotely-operated vehicles.  Read More

Composite of 25 separate images of the Sun captured buy NASA's SDO (Photo: NASA/SDO/AIA/S....

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

Hubble's stunning near-infrared image of the Horsehead Nebula (Image: NASA)

New near-infrared and far-infrared views captured by NASA's Hubble Space Telescope and the European Space Agency's Herschel space telescope have provided a spectacular new look at the famous Horsehead Nebula.  Read More

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

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
