Johns Hopkins Astronomers To Discuss New Satellite Galaxy Simulation
With a new simulation that shows how satellite galaxies orbit bigger galaxies like the Milky Way, Johns Hopkins University researchers have reconciled long-dueling visions of what astronomers actually see using telescopes and what theorists have predicted they should see.
Galaxies in the Infant Universe Were Surprisingly Mature
ALMA telescope conducts largest survey yet of distant galaxies in the early universe
ALMA Shows Volcanic Impact on Io’s Atmosphere
New radio images from the Atacama Large Millimeter/submillimeter Array (ALMA) show for the first time the direct effect of volcanic activity on the atmosphere of Jupiter’s moon Io.
ALMA Discovers Misaligned Rings in Planet-Forming Disk Around Triple Stars
Using the Atacama Large Millimeter/submillimeter Array (ALMA), two teams of astronomers have for the first time discovered a planet-forming disk with misaligned rings around a triple star system, called GW Orionis. The astronomers give two possible scenarios for the misalignment: either…
ALMA Captures Stirred-Up Planet Factory
Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made with the Atacama Large Millimeter/submillimeter Array (ALMA). All planets, including the ones in our Solar System,…
ALMA Finds Possible Sign of Neutron Star in Supernova 1987A
Based on ALMA observations and a theoretical follow-up study, scientists suggest that a neutron star might be hiding deep inside the remains of Supernova 1987A.
2020 Jansky Lectureship Awarded to University of Cornell Professor Martha P. Haynes
AUI and the NRAO have awarded the 2020 Karl G. Jansky Lectureship to Dr. Martha P. Haynes, Goldwin Smith Professor of Astronomy at Cornell University.
Stellar Fireworks Celebrate Birth of Giant Cluster
Astronomers created a stunning new image showing celestial fireworks in star cluster G286.21+0.17.
Supergiant Atmosphere of Antares Revealed by Radio Telescopes
An international team of astronomers has created the most detailed map yet of the atmosphere of the red supergiant star Antares. The unprecedented sensitivity and resolution of both the Atacama Large Millimeter/submillimeter Array (ALMA) and the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) revealed the size and temperature of Antares’ atmosphere from just above the star’s surface, throughout its chromosphere, and all the way out to the wind region.
ALMA Discovers Massive Rotating Disk in Early Universe
In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late. But a new discovery made with the Atacama Large Millimeter/submillimeter Array (ALMA) of a massive rotating disk galaxy, seen when the universe was only ten percent of its current age, challenges the traditional models of galaxy formation. This research appears on 20 May 2020 in the journal Nature.
Exoplanet climate ‘decoder’ aids search for life
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.
Astronomers could spot life signs orbiting long-dead stars
To help future scientists make sense of what their telescopes are showing them, Cornell University astronomers have developed a spectral field guide for rocky worlds orbiting white dwarf stars.
Researchers use ‘hot Jupiter’ data to mine exoplanet chemistry
After spotting a curious pattern in scientific papers – they described exoplanets as being cooler than expected – Cornell University astronomers have improved a mathematical model to accurately gauge the temperatures of planets from solar systems hundreds of light-years away.
The Strange Orbits of ‘Tatooine’ Planetary Disks
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found striking orbital geometries in protoplanetary disks around binary stars. While disks orbiting the most compact binary star systems share very nearly the same plane, disks encircling wide binaries have orbital planes that are severely tilted. These systems can teach us about planet formation in complex environments.
Dimming Betelgeuse likely isn’t cold, just dusty, new study shows
Scientists at the University of Washington and Lowell Observatory report that Betelgeuse is significantly warmer than expected if its recent dimming had been triggered by cooling of the star’s surface. This may indicate that Betelgeuse instead sloughed off material from its outer layers.
How Newborn Stars Prepare for the Birth of Planets
An international team of astronomers used two of the most powerful radio telescopes in the world to create more than three hundred images of planet-forming disks around very young stars in the Orion Clouds. These images reveal new details about the birthplaces of planets and the earliest stages of star formation.
ASU-led NASA Psyche mission offers free online course on team building from leadership experts
The new Psyche Mission Innovation Toolkit online course is designed to help learners understand the unique challenges of a diverse team and provides tools to help address these challenges and take actions to be more successful in working with others.

The Turbulent Life of Two Supermassive Black Holes Caught in a Galaxy Crash
An international team of astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to create the most detailed image yet of the gas surrounding two supermassive black holes in a merging galaxy.
Automated Observing Network Inaugurated at SOAR Telescope
To provide astronomers with a network of world-class telescopes that can be accessed with a touch of a button, four ground-based astronomical observatories have joined forces to set up the Astronomical Event Observatory Network (AEON): Las Cumbres Observatory (LCO), the National Science Foundation’s National Optical Astronomy Observatory (NOAO), the SOAR Telescope, and Gemini Observatory. With AEON, astronomers will be able to automatically follow up on their astronomical objects of interest, with a range of 0.4-meter to 8-meter telescopes, observing in UV light to infrared.
