Here are today's trending topics in astronomy:
- *Swirling Polar Vortices on the Sun*: Researchers have discovered that the Sun likely has swirling polar vortices, similar to those on Earth, but driven by magnetic forces instead of atmospheric conditions ¹.
- *Einstein's Equations and the Universe's Expansion*: Scientists are still trying to solve the mystery of the universe's accelerating expansion, which was discovered 25 years ago. This phenomenon challenges our understanding of the fundamental laws of physics, including Albert Einstein's equations ¹.
- *Black Hole Light Echoes*: Astrophysicists have developed a new technique to search for black hole light echoes, which will make it easier to measure the mass and spin of black holes ¹.
- *Asteroid Grains and the Outer Solar System*: Tiny grains from the asteroid Ryugu are providing clues about the magnetic forces that shaped the outer solar system over 4.6 billion years ago ¹.
- *Dance of Electrons in Neutron-Star Collisions*: Scientists have observed the temperature of elementary particles in the radioactive glow following the collision of two neutron stars and the birth of a black hole ¹.
- *The Fastest-Feeding Black Hole*: Astronomers have discovered a supermassive black hole consuming matter at a phenomenal rate, over 40 times that of other black holes ¹.
