The interacting galaxy pair NGC 1512 and NGC 1510 take center stage in this image from the US Department of Energy-fabricated Dark Energy Camera, a state-of-the-art wide-field imager on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF’s NOIRLab.
At its April 28,2022 meeting the AURA Board of Directors endorsed the following principles for the future management of astronomical facilities on Maunakea.
Alignment of NASA’s James Webb Space Telescope is now complete. After full review, the observatory has been confirmed to be capable of capturing crisp, well-focused images with each of its four powerful onboard science instruments.
NASA’s Hubble Space Telescope has determined the size of the largest icy comet nucleus ever seen by astronomers. The estimated diameter is approximately 80 miles across, making it larger than the state of Rhode Island.
NASA’s Hubble Space Telescope has established an extraordinary new benchmark: detecting the light of a star that existed within the first billion years after the universe’s birth in the big bang—the farthest individual star ever seen to date.
Today NASA released the first image from Webb with all 18 segments focused and functioning together as a single 6.5-meter mirror.
Former NOAO employee Doug Tody, who was the visionary behind the Image Reduction and Analysis Facility (IRAF), has passed away from complications related to cancer.
On Wednesday, February 23, 2022, the U.S. National Science Foundation’s (NSF’s) Daniel K. Inouye Solar Telescope (Inouye Solar Telescope) commenced its first science observations, signaling the start of its year-long operations commissioning phase and a new era of solar science. Over 25 years in the making, the world’s most powerful solar telescope is now poised to revolutionize our understanding of the Sun and its impacts on Earth.
A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA’s Hubble Space Telescope.
This image, taken by astronomers using the US Department of Energy-fabricated Dark Energy Camera on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF’s NOIRLab, captures the galaxy NGC 1566 as it twirls, flinging its arms through the vastness of space. Colloquially nicknamed the Spanish Dancer, this spiral galaxy is often studied by astronomers learning about galaxy groups, stars of different ages, and galactic black holes.
Scientists have had only limited ability to study these objects once discovered, but all of that is about to change with NASA’s James Webb Space Telescope.
This week the Webb telescope team kept the excitement going with two main developments.
Light from a star made its way through the entire telescope for the very first time, and engineering images were acquired!
Today Webb concluded a month of incredible achievements, and we checked off the last box on our deployment “To Do List.” Webb’s last deployment activity, insertion into L2 orbit, is now complete. Although there are many more achievements to look forward to, let’s take a moment to review what the Webb teams accomplished so far.
Sinuous stellar jets meander lazily across a field of stars in new images captured from Chile by the international Gemini Observatory, a Program of NSF’s NOIRLab. The gently curving stellar jets are the outflow from young stars, and astronomers suspect their sidewinding appearances are caused by the gravitational attraction of companion stars.
