The Large and Small Magellanic Clouds are irregular dwarf galaxies and satellites of the Milky Way. The LMC is about 163,000 light-years away and the SMC is about 206,000 light-years away, and their close proximity […]

A research team has investigated long-term X-ray variability in the neutron star NGC 7793 P13, an object thought to be driven by supercritical accretion, where an extraordinary amount of gas falls onto the object and […]

Images captured by NASA’s Parker Solar Probe as the spacecraft made its record-breaking closest approach to the sun in December 2024 have now revealed new details about how solar magnetic fields responsible for space weather […]

Researchers at the University of Hawaiʻi Institute for Astronomy (IfA) are helping reshape how scientists study the sun. The UH-led team has developed a new artificial intelligence (AI) tool that can map the sun’s magnetic […]

Astronomers have produced the first continuous, two-dimensional maps of the outer edge of the sun’s atmosphere, a shifting, frothy boundary that marks where solar winds escape the sun’s magnetic grasp. By combining the maps and […]

Most smaller galaxies may not have supermassive black holes in their centers, according to a recent study using NASA’s Chandra X-ray Observatory. This contrasts with the common idea that nearly every galaxy has one of […]

In a discovery that’s fit for a movie, Northwestern University astronomers have directly imaged a Tatooine-like exoplanet, orbiting two suns. While obtaining an image of a planet beyond our solar system is already rare, finding […]

The European Space Agency’s Swarm mission detected a large but temporary spike of high-energy protons at Earth’s poles during a geomagnetic storm in November. It did this not with the scientific instruments for measuring Earth’s […]

Compelling evidence that the structure of matter surrounding supermassive black holes has changed over cosmic time has been uncovered by an international team of astronomers.This post was originally published on this site

By analyzing the data from the PHANGS-MUSE survey, an international team of astronomers has inspected a nuclear star cluster of the nearby large spiral galaxy Messier 74. The new study presented Dec. 3 on the […]
