V404 Cygni Rings (Credit: X-ray: NASA/CXC/U.Wisc-Madison/S. Heinz et al.; Optical/IR: Pan-STARRS) A spectacular set of rings around a black hole has been captured using NASA’s Chandra X-ray Observatory and Neil Gehrels Swift Observatory. The X-ray images of the giant rings have revealed new information about dust located in our Galaxy, using a similar […]

When it comes to finding exoplanets, size matters, but so does weight.  The larger and heavier the planet, the more likely they will be discovered by the current crop of telescopes.  Both the techniques to find exoplanets and the telescopes using those techniques are biased toward larger, heavier planets.  So […]

When the poet Horace said “We are but dust and shadow”, he probably didn’t think that dust itself could create a shadow. But it can, and that shadow can obscure even some of the most powerful explosions in the universe.  At least that’s the finding from new research from an international team […]

The orphan cloud is the blue umbrella-shaped part of this image, which is color-coded to show the X-ray part of the cloud in blue, the warm gas in red, and the visible region in white. Credit: Ge et al (2021) A scientifically mysterious, isolated cloud bigger than the Milky Way has been […]
