Astronomers Find Progenitor of Magnetic Monster
A team of researchers, including NOIRLab astronomer André-Nicolas Chené, has found a highly unusual star that has the most powerful magnetic field ever found in a massive star — and that may become one of the most magnetic objects in the Universe: a variant of a neutron star known as a magnetar. This finding marks the discovery of a new type of astronomical object — a massive magnetic helium star — and sheds light on the origin of magnetars.

Visitors from Distant Stars: Rubin Observatory Will Detect an Abundance of Interstellar Objects Careening Through Our Solar System
Many as-yet-undiscovered interstellar objects exist throughout our Milky Way Galaxy: comets and asteroids that have been ejected from their home star systems. Some of these objects pass through our Solar System, bringing valuable information about how planetary systems form and evolve. Currently, only two such interstellar visitors have been discovered: 1I/ʻOumuamua and comet 2I/Borisov. Rubin’s upcoming Legacy Survey of Space and Time will show us many more.

Dark Energy Camera Captures Galaxies in Lopsided Tug of War, a Prelude to Merger
The spiral galaxy NGC 1532, also known as Haley’s Coronet, is caught in a lopsided tug of war with its smaller neighbor, the dwarf galaxy NGC 1531. The image — taken by the US Department of Energy’s (DOE) Dark Energy Camera mounted on the National Science Foundation’s (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF’s NOIRLab — captures the mutual gravitational influences of a massive- and dwarf-galaxy merger.

Peering Back to the Early Universe: A Story of Confirmation and Refutation
Last year astronomers using NASA’s James Webb Space Telescope peered back to the very distant, very early Universe and found what appeared to be some of the earliest galaxies ever observed, thought to have formed when the Universe was less than 500 million years old. Using follow-up spectroscopy, two NOIRLab astronomers confirmed the ages of two of these early galaxies, but they also revealed how a third galaxy had astronomers fooled.

Accretion Disks: How Big Are They Really?
Using the Gemini North telescope, one half of the International Gemini Observatory, operated by NSF’s NOIRLab, astronomers have detected for the first time evidence of the presence of an accretion disk within the active galactic nucleus of galaxy III Zw 002. Using two rare and peculiar near-infrared emission lines, these observations place firm limits on the size of the galaxy’s accretion disk and shed new light on its geometry and behavior.

An Enigmatic Cosmic Crime Scene
During a dive through archival data, astronomers unearth an unusual tidal disruption event that occurred in a nearby star-forming galaxy. Obscured by the interstellar medium, this incredibly close and luminous event went unnoticed for seven years. The SOAR telescope’s integral role in pinpointing its uncommon location illustrates how future searches for tidal disruption events will be conducted.

The Dark Energy Survey: Uncovering the Invisible
The Dark Energy Survey was a six-year observing program designed to survey the skies in order to better understand dark energy — a complex concept that developed when scientists realized that the Universe seemed to be breaking its own supposedly immutable laws of physics. But how do you observe something that cannot be seen? And why are scientists so convinced that there is really something to search for?
From the first observations in 1965, Cerro Tololo, located in Chile, has served as the principal platform for U.S. astronomical investigation of the southern skies.
Programs within the Community Science and Data Center support and enable a broad range of astronomical community science activities across the US ground-based optical and infrared system.
Founded in 1958, Kitt Peak National Observatory is home to one of the largest arrays of optical and radio telescopes in the world.
The Gemini Observatory consists of twin 8.1-meter diameter optical/infrared telescopes located on two of the best observing sites on the planet.
Vera C. Rubin Observatory, currently under construction on Cerro Pachón in Chile, is an 8-meter-class telescope coupled to a 3.2-gigapixel camera – the world’s largest digital camera ever fabricated for optical astronomy.
