Spirals of solar wind can spin off larger solar eruptions and disrupt Earth’s magnetic field, yet they are too difficult to detect with our current single-location warning system, according to a new study from the […]

In principle, discovering new exoplanets is pretty easy. Simply measure the brightness of a star over time, and when a planet passes in front of the star, the brightness will dim slightly. The more the […]

A hundred years before the Event Horizon Telescope Collaboration released the first image of a black hole in 2019—located at the heart of the galaxy M87—astronomer Heber Curtis had already discovered a strange jet protruding […]

Using the Very Energetic Radiation Imaging Telescope Array System (VERITAS), German astronomers have observed a unique microquasar known as SS 433. Results of the observational campaign, published Sept. 25 on the arXiv pre-print server, could […]

A mysterious “rogue” planet has been observed gobbling six billion tons of gas and dust a second—an unprecedented rate that blurs the line between planets and stars, astronomers said Thursday.This post was originally published on […]

Scientists have unveiled a new approach to detecting gravitational waves in the milli-Hertz frequency range, providing access to astrophysical and cosmological phenomena that are not detectable with current instruments.This post was originally published on this […]

Since the early 20th century, scientists have gathered compelling evidence that the universe is expanding at an accelerating rate. This acceleration is attributed to what is known as dark energy—a fundamental property of spacetime that […]

The most distant and most powerful “odd radio circle” (ORC) known so far has been discovered by astronomers. These curious rings are a relatively newly identified astronomical phenomenon, having been detected for the first time […]

Astronomers have identified an enormous “growth spurt” in a so-called rogue planet. Unlike the planets in our solar system, these objects do not orbit stars, free-floating on their own instead. The new observations, made with […]

Astronomers report the discovery of two new highly scattered pulsars as part of the Australian SKA Pathfinder (ASKAP) Variables and Slow Transients (VAST) survey. The findings are detailed in a research paper published September 24 […]
