New Radio Images of Bizarre “Odd Radio Circles” Which are Vastly Bigger Than the Milky Way
In radio astronomy, circle-shaped objects are fairly common. Since diffuse ionized gas often emits radio light, objects such as supernova remnants, planetary nebulae, and even star-forming regions can create circular arcs of diffuse gas. But in 2019 astronomers began to discover radio circles they couldn’t explain, in part because they are so large.

Astronomers Discover two Supermassive Black Holes Orbiting Each Other, Doomed to Collide in the Future.
Until recently, one of the closest orbiting each other pairs of supermassive blackholes was found in NGC 7727. That pair is about 89 million light-years away from Earth. Those black holes are only 1,600 light-years apart from each other. Another pair in OJ 287, about 3.5 billion light-years from Earth, are only separated by about 0.3 light years. Now scientists have discovered a pair orbiting each other at a distance of 200 AU to 2,000 AU apart, about 0.003 to 0.03 light years.
Life as we know it would not exist without this highly unusual number
The fine-structure constant is a seemingly random number with no units or dimensions, which has cropped up in so many places in physics, and seems to control one of the most fundamental interactions in the universe.

Three Cosmonauts Arrive at the ISS Wearing Bright Yellow Jumpsuits
About a month ago, Russian forces invaded Ukraine, placing NATO on high alert and creating a shock wave felt around the world. One place that has been particularly resilient to the effects of this conflict is the International Space Station (ISS). Even as tensions mount and the heads of space agencies engage in an online war of words, astronauts and cosmonauts continue to work and live together in orbit.
