An international team of researchers has confirmed that a possible microlensing event witnessed in 2011 was due to the presence of a free-floating black hole roaming through interstellar space—the first of its kind ever ...
Dozens of space-based telescopes operate near Earth and provide incredible images of the universe. But imagine a telescope far away in the outer solar system, 10 or even 100 times farther from the sun than Earth. The ability ...

A pair of researchers at the Czech Academy of Sciences has been shaking up the astrophysics community with a new modified Newtonian dynamics (MOND) theory that tosses out the concept of dark matter and instead backs up theories ...
Gazing into the universe is like looking into a funhouse mirror. That's because gravity warps the fabric of space, creating optical illusions.
