Press Releases 2022

22 February 2022: This image, taken by astronomers using the US Department of Energy-fabricated Dark Energy Camera at Cerro Tololo Inter-American Observatory, a Program of NSF 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.

15 February 2022: NOIRLab's Journey Through the Universe — returning with an online program this year — will share the wonders of the Universe and career awareness in science and technology with Hawaiʻi students. In partnership with the Hawaiʻi Department of Education Hilo-Waiakea Complex Area, this year’s implementation of the flagship astronomy outreach program consists of a week of virtual programming along with a new cultural exchange program between classrooms in NOIRLab’s host cities in Hawaiʻi, Chile, and Arizona.

3 February 2022: At a press conference today, NSF NOIRLab announced that it has been selected, along with the SKA Observatory (SKAO), by the International Astronomical Union to host the new IAU Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference. The center coordinates collaborative multidisciplinary international efforts with institutions and individuals and works across multiple geographic areas to help mitigate the negative impact of satellite constellations on ground-based optical and radio astronomy observations as well as humanity’s enjoyment of the night sky.

1 February 2022: By scanning the sky very close to the horizon at sunrise, the SOAR Telescope in Chile, part of Cerro-Tololo Inter-American Observatory, a Program of NSF NOIRLab, has helped astronomers confirm the existence of only the second-known Earth Trojan asteroid and reveals that it is over a kilometer wide — about three times larger than the first.

20 January 2022: 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 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. These crystal-clear observations were made using the Gemini South telescope’s adaptive optics system, which helps astronomers counteract the blurring effects of atmospheric turbulence.

13 January 2022: The Dark Energy Spectroscopic Instrument (DESI) has cataloged more galaxies than all other previous three-dimensional redshift surveys combined, measuring 7.5 million galaxies in only seven months since beginning science operations. The US Department of Energy's Lawrence Berkeley National Laboratory leads DESI, which is installed at Kitt Peak National Observatory, a program of NSF NOIRLab, on the Nicholas U. Mayall 4-meter Telescope.

12 January 2022: Using the 4.1-meter SOAR Telescope in Chile, astronomers have discovered the first example of a binary system where a star in the process of becoming a white dwarf is orbiting a neutron star that has just finished turning into a rapidly spinning pulsar. The pair, originally detected by the Fermi Gamma-ray Space Telescope, is a “missing link” in the evolution of such binary systems.

5 January 2022: A primordial stellar stream discovered in the outer reaches of the Milky Way has a lower proportion of heavy elements than any known stellar system in our galaxy. Observations with the Gemini Observatory, a Program of NSF NOIRLab, showed that the stars in this stream were torn from an ancient star cluster and are relics from the early days of the Milky Way, which could provide insights into the formation of the first stars.
