Little red dots may reside in small, dense galaxies with total masses equivalent to around 1 billion times that of the sun, according to research published in Nature Astronomy.This post was originally published on this […]

The universe is known to be expanding at an accelerating rate. Physicists typically attribute this acceleration to dark energy, a mysterious component of the universe that exerts negative pressure, causing space to expand faster. Dark […]

At the center of our solar system, the sun influences every planet that orbits it. In two recent studies, scientists uncovered how ancient events in the sun’s history may have helped create Earth’s unique climate […]

On Aug. 15, the CTAO LST Collaboration and the MAGIC Collaboration released findings from observations of OP 313, the most distant very-high-energy blazar ever recorded. The paper, published in Astronomy & Astrophysics, presents in-depth observations […]

Astronomers have found a four-star system doing something that has never been confirmed before. The system, TIC 433545934, has two close pairs of stars orbiting each other. While each pair eclipses its own two stars, […]

Science seems like a straightforward endeavor. You come up with a hypothesis, collect data to prove or disprove it, and analyze that data to see whether the hypothesis is right. But anyone who actually does […]

An international team of astrophysicists and plasma physicists has provided the first experimental evidence that strong magnetic fields surrounding active stars can completely suppress coronal mass ejections. This offers clues to why massive stellar eruptions […]

At the center of most galaxies lies a supermassive black hole, with a mass millions to billions of times that of our sun and some of the most extreme gravity in the universe.This post was […]

Welcome back to our series on interstellar travel! In our first installment, we examined attempts to realize nuclear propulsion and how the technology could be used to reach the nearest star. In our second, we […]

Astronomers have discovered a chemically rich collection of sulfur-bearing molecules surrounding the rare massive star HD 87643. The observations include the first detection of sulfur monoxide and sulfur dioxide around a B[e] supergiant. The paper […]
