The Hubble Space Telescope is commemorating its 25th anniversary with a second look at the Pillars of Creation — but there’s hard science behind these pretty pictures.
Last year the University of California ordered its astronomers to make historic Lick Observatory self-supporting by 2018. Now there's been a change of heart, and the university will continue to pay for its operation.
An ALMA submillimeter-wavelength image unveils the dawn of planet formation around a surprisingly young star in unprecedented detail.
The University of Hawai'i, in partnership with the University of Arizona and Lockheed Martin, will sustain operations of the UKIRT infrared telescope.
Officials proceeded with groundbreaking ceremonies for the world's largest optical telescope on October 7th amid protests from native Hawaiians who oppose it.
The Subaru Telescope has donned a new pair of glasses called Raven, a multi-object adaptive optics system that enables astronomers to correct for atmospheric turbulence over an unprecedented field of view.
The top of Cerro Armazones in Chile yielded on June 19th to a blast that paves the way for the European Extremely Large Telescope.
A new processing technique has revealed once-invisible planetary disks encircling five stars imaged in Hubble’s archive.
Amateur astronomers have teamed up with the pros to produce four stunning multiwavelength images of galaxies M101, M81, M51, and Centaurus A.
Miniature robots crawling along glass plates will help big surveys collect light from hundreds of thousands of galaxies.
Astronomy is ready for the next generation of detectors, and superconductors are at the heart of the coming revolution.
After four years of exquisite observations, the latest mission to study the universe's earliest light has been shuttered. But this end is a happy one and comes with a significant cosmological legacy.
The 17-day strike at the world’s largest ground-based observatory ended Saturday, and ALMA's revolutionary observations of the millimeter/submillimeter sky restart today.
Threatened by NSF cuts, the Green Bank Telescope signed a deal with West Virginia University to receive $1 million over the next two years. But the radio antenna will need more than that to survive long-term.
Time and tide wait for no man. So the XMM-Newton space telescope is making every second count. As the telescope shifts its gaze from source to source, it's recording the X-ray sky.
Twinkle, twinkle, quasi-star: cosmic lenses could tell us what you are.
Solar physicists hope NASA’s latest space observatory, the Interface Region Imaging Spectrograph, can finally discover what heats the Sun’s million-degree corona.
The stars were not aligned when one of Sky & Telescope's editors signed up to ride NASA's Stratospheric Observatory for Infrared Astronomy.
From international travel to interplanetary probes, the U.S. budget cuts are having impacts on both ground- and space-based astronomy.
Astronomers have been waiting for our galaxy’s slumbering supermassive black hole to stir for a snack. Instead, the universe handed them a different treat.
After nearly four years of successful observing, the largest infrared space telescope ever launched has run out of cryogenic coolant, permanently ending its science operations.
Astronomers have announced a new class of gamma-ray bursts, possibly created when some of the biggest stars in the universe go supernova.
The future is now — the world’s most powerful radio telescope array was inaugurated yesterday.
Yesterday bushfires swept through Australia's Warrumbungle National Park, home to Siding Spring Observatory. The telescopes there appear to have escaped harm, but some support facilities and staff homes were destroyed.
NASA’s newest high-energy X-ray telescope has released two stunning images of a stellar explosion and ravenous black holes.
