This image shows the Hyades star cluster, the nearest cluster to us. The Hyades cluster is very well studied due to its location, but previous searches for planets have produced only one. A new study led by Jay Farihi of the University of Cambridge, UK, has now found the atmospheres of two burnt-out stars in this cluster ??? known as white dwarfs ??? to be ???polluted??? by rocky debris circling the star. Seeing evidence of asteroids points to the possibility of Earth-sized planets in the same system, as asteroids are the building blocks of major planets. Planet-forming processes are inefficient, and spawn many times more small bodies than large bodies ??? but once rocky embryos the size of asteroids are built, planets are sure to follow.

Crooked star clusters may be a sign that Einstein’s gravity is wrong

Astronomers have found an unexpected asymmetry in stars escaping from their clusters, and it can't be easily explained by our standard theories of gravity

Magnetic fields in NGC 1068, or M77, are shown as streamlines over a visible light and X-ray composite image of the galaxy from the Hubble Space Telescope, the Nuclear Spectroscopic Array, and the Sloan Digital Sky Survey. The magnetic fields align along the entire length of the massive spiral arms ? 24,000 light years across (0.8 kiloparsecs) ? implying that the gravitational forces that created the galaxy?s shape are also compressing its magnetic field. This supports the leading theory of how the spiral arms are forced into their iconic shape known as ?density wave theory.? SOFIA studied the galaxy using far-infrared light (89 microns) to reveal facets of its magnetic fields that previous observations using visible and radio telescopes could not detect.
