Using archival data from the Gemini North telescope, a team of astronomers have measured the heaviest pair of supermassive black holes ever found. The merging of two supermassive black holes is a phenomenon that has long been predicted, though never observed. This massive pair gives clues as to why such an event seems so unlikely in the Universe.

Usando datos de archivo del telescopio Gemini Norte, un equipo de astrónomos midió un par de agujero negros supermasivos, los más pesados jamás encontrados. La fusión de estos agujeros negros supermasivos es un fenómeno que se predice desde hace mucho tiempo, aunque nunca se ha observado. Este par masivo nos entrega pistas de por qué un evento como este es tan improbable en el Universo.

The recent spike of activity from the sun occurred during what NASA has dubbed the Heliophysics Big Year—a celebration of solar science centered on the April 8 total eclipse, the last that will be visible from the continental U.S. for 20 years.
Most sighting reports of Unidentified Anomalous Phenomena occur in the American West where proximity to public lands, dark skies and military installations afford more opportunities to see strange objects in the air. Understanding environmental context may help identify truly anomalous objects that are a legitimate threat.
A new computer platform called TCL 3.0 represents a breakthrough in how scientists measure and monitor changes in tiger habitat and provides a framework for monitoring other wildlife species across the globe.
Scientists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory are working on ways to improve thrusters for satellites operating in very low orbit around the Earth. The researchers believe they can make satellites that weigh less, last longer and cost less by creating thrusters that use the air around them instead of having to carry its own supply of fuel. PPPL’s diagnostics will be used to evaluate this innovative thruster concept and characterize key physical processes involved in its operation.
Dark matter comprises over 80% of all matter in the cosmos but is invisible to conventional observation, because it seemingly does not interact with light or electromagnetic fields. Now Dr. Sukanya Chakrabarti, the Pei-Ling Chan Endowed Chair in the College of Science at The University of Alabama in Huntsville (UAH), along with lead author Dr. Tom Donlon, a UAH postdoctoral associate, have written a paper to help illuminate just how much dark matter there is in our galaxy and where it resides by studying the gravitational acceleration of binary pulsars. Chakrabarti gave a plenary talk on this work and other methods to measure galactic accelerations at the 243rd meeting of the American Astronomical Society in New Orleans in January.
In the three years since NASA’s Perseverance rover touched down on Mars, the NASA science team has made the daily task of investigating the red planet seem almost mundane.

How does ground-based astronomical radar expand our understanding of the Universe? By allowing us to study our nearby Solar System, and everything in it, in unprecedented detail. Radar can reveal the surface and ancient geology of planets and their moons, letting us trace their evolution.
A team including University of Idaho researchers is going to explore the physics of supermassive black hole mergers and galaxy collisions, unlocking secrets that could reshape science’s understanding of one of the universe’s most enigmatic processes.
In our most basic understanding of our Solar System, planets are drawn into the orbit of our massive star, the Sun. But what happens to planet-sized objects that don’t have a star? A team of astronomers studying Jupiter-mass binary objects (JuMBOs) in the Orion Nebula are gaining a new understanding of these unusual systems.
Though far to the west of the St. Croix antenna, the Owens Valley antenna has some similarities, in particular being in a remote location. The high mountains surrounding the valley mean that access to the region is only possible from the south, or through mountain passes. This also makes for a unique geography. To the south are the dry bed remains of Owens Lake, and further beyond is Death Valley. To the East are the White Mountains, which is home to the great bristlecone pine forest, and some of the oldest living trees in the world. Within the Methuselah Grove of this forest is hidden a particular tree that was seeded nearly 5,000 years ago.
SuperKnova is a project to provide learning opportunities in radio technology for students in a way that is inclusive and equitable. Originally conceived at the Radio Astronomy Imaging and Analysis Lab (RADIAL), SuperKnova is a collaboration between RADIAL, NRAO, and educators and students from across the country.
Scientists working with the powerful telescopes at Georgia State’s Center for High Angular Resolution Astronomy (CHARA) Array have completed a survey of a group of stars suspected to have devoured most of the gas from orbiting companion stars.
100 billion – there are at least that many stars in our Milky Way. It seems like an unimaginable number. Yet astrophysicists study structures in our universe that are far bigger than galaxies alone.
When galaxies go bump in the night, they cook-up new generations of stars that might otherwise have never been born. These close encounters between galaxies cause a gravitational tug-of-war.
El Observatorio Vera C. Rubin ayudará a los científicos a identificar objetivos intrigantes para dar prioridad a futuras misiones espaciales, mediante la detección de millones de nuevos objetos en el Sistema Solar y revelar, con el mayor detalle jamás visto, el contexto más amplio en el que existen.

With a panoramic view 200 times larger than the Hubble Space Telescope’s infrared view, the sheer amount of data captured by the upcoming Nancy Grace Roman Space Telescope will change the landscape of astronomy.
Employing massive data sets collected through NASA’s James Webb Space Telescope, a research team led by a Rutgers University–New Brunswick astronomer is unearthing clues to conditions existing in the early universe. The team has catalogued the ages of stars in the Wolf–Lundmark–Melotte (WLM) galaxy, constructing the most detailed picture of it yet, according to the researchers.
