The globular cluster M53, imaged here by the Hubble Space Telescope, is home to mostly older stars – but also a population of strange, young-looking blue straggler stars.

Even if you knew nothing about astronomy, you’d understand that exploding stars are forceful and consequential events. How could they not be? Supernovae play a pivotal role in the Universe with their energetic, destructive demises. There are different types of supernovae exploding throughout the Universe, with different progenitors and different remnants. The Zwicky Transient Facility … Read more
HBO’s “Dune: Prophecy” is lurching towards its season finale on Dec. 22, but before we’re further embroiled in the heated court politics of House Corrino and Valya Harkonnen’s vengeful thirst for power and Sisterhood control comes to a head, fans were treated to some intimate time with the two brooding patriarchs, Evgeny Harkonnen (Mark Addy) … Read more
Exomoons are a hot topic in the science community, as none have been confirmed with astronomers finding new and creative ways to identify them. But while astronomers have searched for exomoons orbiting exoplanets around single stars like our Sun, could exomoons exist around exoplanets orbiting binary stars? This is what a recent study submitted to … Read more
A superflare erupts from a young sunlike star in this artist’s impression. Credit: CfA/Melissa Weiss Solar flares are bright flashes of light from the Sun that release large amounts of electromagnetic radiation. And while normal flares can release as much as 1025 joules of energy, so-called superflares, observed on other stars, are up to 10,000 … Read more
High-energy, powerful, and violent stellar explosions called “superflares” have been found to erupt from stars like the sun roughly once every 100 years, making these blasts far more common than scientists had thought. Solar flares, eruptions of high-energy radiation, can have serious effects on Earth, with the potential to impact communication systems and power infrastructure. … Read more
Death by black hole isn’t always inevitable for stars that exist in binary systems with one of these cosmic titans. There may be a way for small stars in such systems to dodge their expected fates: violent supernovas that end in the creation of another black hole. This expected mechanism is also believed to turn … Read more
