Tracking down black holes at the center of dwarf galaxies has proven difficult. In part it is because they have a tendency to “wander” and are not located at the galaxy’s center. There are plenty […]

Researchers using the NASA/ESA/CSA James Webb Space Telescope have confirmed an actively growing supermassive black hole within a galaxy just 570 million years after the Big Bang. Part of a class of small, very distant […]

Astronomers know that mergers play a huge role in galaxy growth. Right now, the Milky Way is slowly consuming the Large and Small Magellanic Clouds. The evidence is a stream of gas called the Magellanic […]

Using high-resolution 1665/1667 MHz OH line and continuum spectrum observational data from the European VLBI Network and the Multi-Element Radio Linked Interferometer Network, Antneh Gashaye, a Ph.D. student from the Xinjiang Astronomical Observatory of the […]

Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has inspected a distant galaxy designated MACS0416_Y1. Results of the observations, presented Nov. 11 on the arXiv pre-print server, indicate that MACS0416_Y1 is […]

Let’s rewind the clock back…oh, I don’t know, let’s say a hundred years. It was 1917, and Einstein had just developed his general theory of relativity. It was a masterpiece, giving us our modern-day view […]

The international LIGO-Virgo-KAGRA Collaboration has completed the fourth observation campaign (called O4) of the international network of gravitational wave detectors. Launched in May 2023, the campaign ends after a period of coordinated observations lasting over […]

All around us are elements forged in stars, from the nickel and copper in coins to the gold and silver in jewelry. Scientists have a good understanding of how these elements form: In many cases, […]

Our search for exoplanets is focused on Milky Way stars. It’s been successful, with more than 6,000 detected so far. Scientists are even beginning to move beyond mere detections, and working on characterizing other characteristics […]

All motion is relative. That simple fact makes tracking the motion of distant objects outside our galaxy particularly challenging. For example, there has been a debate among astronomers for decades about the path that one […]
