The illustration above shows a star behind a shattered comet. Scientists initially believed the strange behavior of the star KC 8462852 was caused by dusty comet fragments that blocked the light of the star, causing it to occasionally dim. (NASA/JPL-Caltech) A star that has long puzzled scientists with its strange behavior has suddenly dimmed again, andresearchers worked to observe its odd actions. On May 19, astronomers noticed than it had been a few days prior, according to a website dedicated...

New telescope images show a dying giant star collapsing into a black hole instead of going supernova. ...

At a Glance Astronomers were able to observe dying star turning into a black hole.The event may help explain why not all stars become supernovae when they expire.Questions remain about the origin of black holes. A dying star 25 times the size of our sun has likely been reborn as a black hole, giving astronomers key insights into the life cycles of supernovae and black holes. Instead of exploding in a massive supernova, the star instead fizzled out, leaving behind...

At a Glance The latest discovery shows these waves can be anywhere in the sky.Two black holes, which likely were originally far apart, eventually merged into a giant one, researchers say. Astronomers said Thursday they detected a third ripple in the fabric of space-time, a remnant of a cosmic crash of two black holes 3 billion years ago. These invisible ripples, called gravitational waves and first theorized by Albert Einstein, first burst into science's view to great fanfare in February...

This image shows an artist's impression of the giant, ringed gas planet orbiting the star PDS 110. (University of Warwick) At a Glance Scientists have determined a giant, ringed gas planet may be causing eclipses of a star more than 1,000 light years away.The possible planet may be up to 50 times larger than Jupiter.The next eclipse will occur in September. Saturn is theplanet in our cosmic lineup known best for its rings, but researchers say a massive gas planet...
