Space Photos of the Week: Dead Stars and a Cute L’il Comet

This ghostly image captures a death. The red filaments of gas are remnants of a supernova explosion called HBH 3. Astronomers think it happened anywhere between 80,000 and 1 million years ago, and these markers stretch 150 light years across—among the largest supernova remnants ever discovered. And while the red ...

A new map for a birthplace of stars

A Yale-led research group has created the most detailed maps yet of a vast seedbed of stars similar to Earth’s Sun. The maps provide unprecedented detail of the structure of the Orion A molecular cloud, the closest star-forming region of high-mass stars. Orion A hosts a variety of star-forming environments, ...

The Shift: Facebook’s Other Critics: Its Viral Stars

Glenn Harvey For the past two years, Ryan Hamilton has been getting Facebook-famous. Mr. Hamilton, 28, manages a network of Facebook pages and makes viral videos for his “Hammy T.V.” channel — mostly lowbrow fare with titles like “Shocking Pit Bull Social Experiment” and “World’s Hottest Pepper on Girlfriend’s Thong” ...

Space Photos of the Week: Where Stars Go to Live and Die

As Carl Sagan once said, “We are made of star stuff.” And so is everything in the universe. When a star explodes, it leaves behind traces that can tell you about its elemental makeup, and Cassiopeia A is a great example of those supernova remnants. The Chandra X-ray observatory snapped ...

Squishy or Solid? A Neutron Star’s Insides Open to Debate

The alerts started in the early morning of Aug. 17. Gravitational waves produced by the wreck of two neutron stars—dense cores of dead stars—had washed over Earth. The thousand-plus physicists of the Advanced Laser Interferometer Gravitational-Wave Observatory rushed to decode the space-time vibrations that rolled across the detectors like a ...

Explosive birth of stars swells galactic cores

Astronomers found that active star formation upswells galaxies, like yeast helps bread rise. Using three powerful telescopes on the ground and in orbit, they observed galaxies from 11 billion years ago and found explosive formation of stars in the cores of galaxies. This suggests that galaxies can change their own ...

What Happens When Two Neutron Stars Collide? Scientific Revolution

Late last week, as some staff astronomers embarked on trips to see Monday’s solar eclipse, two of NASA’s space-based observatories—Hubble and Chandra X-ray—and at least two land-based telescopes scrambled to capture a far more explosive event. The astronomers who stayed behind trained their telescopes on a patch of sky where ...
