A New Theory of Dark Matter Could Solve Three Cosmic Mysteries

A study led by UC Riverside physicist Hai-Bo Yu suggests that a new type of dark matter could explain three astrophysical puzzles across vastly different environments. from Universe Today https://ift.tt/NDXHhZ1 via IFTTT

Turbulence in the Milky Way's ISM Distorts Light from Distant Quasars

We may be getting better images of the Milky Way's supermassive black hole in the future. Astronomers used 10 years of observations of a distant blazar to detect turbulence in the Milky Way's interstellar medium. This turbulence makes images of Sagittarius A-star blurry. from Universe Today https://ift.tt/0MsN35a via IFTTT

It's Raining Stardust. It Has Been for Thousands of Years.

Right now, as you read this, Earth is drifting through a cloud of debris from an ancient stellar explosion. Stardust, real stardust, is raining down on us so thinly scattered that we have only just found the proof. Locked inside Antarctic ice cores up to 80,000 years old, an international team led by the Helmholtz-Zentrum Dresden-Rossendorf has discovered traces of iron-60, a radioactive isotope that can only be created in the heart of an exploding star. from Universe Today https://ift.tt/VoXSinK via IFTTT

We've Been Listening for Ten Years. Here's What We Heard

For ten years, astronomers at UCLA have been pointing one of the world's most powerful radio telescopes at the stars and listening. Not for pulsars or gas clouds, or the hiss of the cosmic microwave background, but for something far more extraordinary. A signal from another civilisation. The result of a decade's work, 70,000 stars, and 100 million candidate signals is now in and every single one of them was us! But far from being a disappointment, the findings are among the most rigorous and revealing in the history of the search for extraterrestrial intelligence. from Universe Today https://ift.tt/PqcaSxb via IFTTT

UC Student Gets a Closer Look at Lonely Gas Giant

University of Cincinnati astrophysicist Paul Smith is part of an international team studying TOI-2031Ab, a gas giant orbiting a star 901 light years from Earth. Smith and his colleagues used the James Webb Space Telescope to study its atmosphere. from Universe Today https://ift.tt/3MEye6s via IFTTT
