Before DESI, the Dark Energy Spectroscopic Instrument, can begin its 5-year mission from an Arizona mountaintop to produce the largest 3D sky map yet, researchers first needed an even bigger 2D map of the universe.Read more
Astronomers have discovered the most distant quasar yet found. The quasar is seen as it was only 670 million years after the Big Bang, and is providing valuable clues about how huge black holes and their host galaxies formed in the early Universe.
Comparing data from VLA sky surveys made some two decades apart revealed that the black hole-powered “engines” at the cores of some distant galaxies have launched new, superfast jets of material during the interval between the surveys.
New VLA images show how the crowded environment of a cluster of galaxies affects the individual galaxies, helping astronomers better understand some of the complex details of such an environment.
ALMA telescope conducts largest survey yet of distant galaxies in the early universe
New Brunswick, N.J. (Oct. 15, 2020) – Blakesley Burkhart’s childhood days spent volunteering at a science museum and watching theRead more
Winners in NRAO’s VLA 40th Anniversary Image Contest are from around the world, and their works illustrate a fascinating variety of celestial objects. Entries combined observational data from the VLA with data from optical, infrared, and X-ray telescopes, and from computer simulations.Read more
Rutgers astronomers have produced the most advanced galaxy simulations of their kind, which could help reveal the origins of the Milky Way and dozens of small neighboring dwarf galaxies. Their research also could aid the decades-old search for dark matter, which fills an estimated 27 percent of the universe. And the computer simulations of “ultra-faint” dwarf galaxies could help shed light on how the first stars formed in the universe.Read more
A new image from the VLA dramatically reveals the extended magnetic field of a spiral galaxy seen edge-on from Earth.Read more
A cosmic measurement technique independent of all others adds strong evidence pointing to a problem with the current theoretical model describing the composition and evolution of the Universe.
Despite a temporary shutdown of the Dark Energy Spectroscopic Instrument in Arizona – which was in its final stages of testing in preparation to begin mapping millions of galaxies in 3D when the pandemic struck – a variety of project tasks are still moving forward.Read more
After examining a dozen types of suns and a roster of planet surfaces, Cornell University astronomers have developed a practical model – an environmental color “decoder” – to tease out climate clues for potentially habitable exoplanets in galaxies far away.Read more
