Zeta Oviucci once orbited close to another star, before its companion was destroyed in a supernova explosion. Infrared data from Spitzer revealed shockwaves made of material that exploded from the star’s surface and collided with gas on its way. Chandra’s data show X-ray emission bubbles located around the star, generated by gas heated to tens of millions of degrees by the shock wave. Chandra’s data helps tell more about the story of this wild star. credit: X-ray: NASA/CXC/Univ. Cambridge / c. Cesc Raines et al; Radio: NSF/NRAO/VLA; Optics: PanSTARRS Zeta Ophiuchi is the only star that may ever have a companion destroyed during a supernova. The supernova explosion sent zeta Ophiuchi into space as seen in the Spitzer data (in green and red) and Chandra (in blue). The X-rays that Chandra discovered came from heating the gas to millions of degrees by the shockwave effect. Scientists are working to match the computational model of this object to interpret the data ...

Not all stars enjoy just wandering around, orbiting the galactic center with all the other stars. Some stars go rogue, crossing the Milky Way with significant force. It is a runaway star, and we can trace its trajectory to understand the violent events that could occur in the Universe. One such star, and one of the more famous ones, is Zeta Ophiuchi. Located about 440 light-years from Earth in the equatorial constellation Ophiuchus, it is also one of the strangest stars in the sky. Not only is it incredibly fast, at about 30 to 40 kilometers (roughly 20 to 25 miles) per second, but it’s a strange type of star to see roaring in space. Zeta Ophiuchi is the main sequence star; that is, one that still combines hydrogen into helium in its core. And it’s a hot, massive O-type star: about 20 times the mass of the Sun, glowing blue with intense heat. Such stars also have relatively short lives; Zeta Ophiuchi is about half way past the main sequence’s projected age of 8 m...

A newly discovered star, now called S4716, is moving at 5,000 miles (8,000 km) per second around the black hole at the center of our galaxy, the Milky Way, space.com reported. The vast expanse of our universe means that astronomers are always discovering something they’ve never seen before. Earlier this week, astronomers spotted two asteroids the size of a bus heading for Earth, which will pass just a quarter of the distance that separates the Moon from us. In addition to asteroids, our galaxy is also attracting the attention of astronomers looking for signs of other planets that support life. Right at the center of the Milky Way, there is a supermassive black hole dubbed Sagittarius A* or Sgr A* and S4716 orbits this black hole at high speed. What we know about S4716 From observations made so far, we know that at 5,000 miles (8,000 km) per second or 18 million miles (29 million km) per hour, S4716 is the fastest star orbiting Sgr A*. It completes an orbit around a black hole ...
