Universe Today 24 Feb 2021, 20:37 UTC Binary star systems are everywhere. They make up a huge percentage of all known solar systems: from what we can tell, about half of all Sun-like stars have a binary partner. But we haven’t really had a chance to study them in detail yet. That’s about to change. Using data from the European Space Agency’s Gaia spacecraft, a research team has just compiled a gigantic new catalog of nearby binary star systems, and it shows that at least 1.3 million of them exist within 3000 light-years of Eart

Bad Astronomy 23 Feb 2021, 14:00 UTC Using one of the largest optical light telescopes in the world, astronomers have identified one of the rarest beasts in the Universe: An extremely distant type of galaxy called a BL Lac object, a galaxy's supermassive black hole spewing out a beam of energy so powerful it dwarfs the light of the entire galaxy it comes from.
SciTech Daily 23 Feb 2021, 11:10 UTC A team of scientists has detected the presence of a high-energy neutrino — a particularly elusive particle — in the wake of a star’s destruction as it is consumed by a black hole. This discovery sheds new light on the origins of Ultrahigh Energy Cosmic Rays — the highest energy particles in the Universe.
Lights in the Dark 22 Feb 2021, 21:45 UTC On February 18, 2021, NASA’s Perseverance rover successfully landed on Mars, becoming the fifth robotic rover to do so and the third operational exploration robot currently on the planet’s surface. Today during a press conference NASA released stunning high-definition video from Perseverance’s entry, descent, and landing (EDL) sequence to the anticipation and excitement of scientists and space enthusiasts alike.
