  Cosmic sleuths are attempting to locate one of the estimated one billion neutron stars in the Milky Way–the collapsed core of a doomed supergiant star with the density of atomic nuclei–that was ejected from the blast of a supernova in the Small Magellanic Cloud, a satellite galaxy to our Milky Way 1,700 years ago during the decline of the Roman Empire. The light of a supernova is visible across billions of light years, releasing as much energy in an instant as our sun will produce over i...

Astronomers using the Hubble Space Telescope to study a supernova remnant in the Small Magellanic Cloud have determined light from the blast reached Earth 1,700 years ago during the decline of the Roman Empire. While it would have been visible to inhabitants of the southern hemisphere, there are no known records of any observations. Located some 200,000 light years away, the remnant is known as 1E 0102.2-7219. As shown below, gaseous knots in the expanding cloud of debris that are headed in Ear...

Astronomers have used the Hubble Space Telescope to turn back time and determine a more accurate estimate of a supernova explosion's location and time. The star

About 200,000 years ago, a massive star in a nearby companion galaxy to the Milky Way exploded. Blasting octillions of tons of debris outwards at high velocity, the explosion has been expanding into space ever since. Today it looks like a swirl of cirrus clouds, its huge velocity diminished almost to motionlessness by distance. But the actual expansion is measurable, and by using a clever technique that runs the clock on it backwards, astronomers have determined when the light of the explosion ...

About 200 thousand light-years away, near the outskirts of the Small Magellanic Cloud, a five million years young star cluster dazzles with bright, blue, newly formed stars.  "Inside the star cluster, bright, blue, newly formed stars are blowing a cavity in this nebula, sculpting the inner edge of its outer portions, slowly eroding it away and eating into the material

Travelling Back in Time Can Help Us Calculate How Old Supernovas Are FOLLOW US ON: While time-travel, as shown in fiction, isn’t a reality, looking back in time to discover the secrets of the universe can be done. Astronomers at NASA are doing a similar thing. According to the space agency, they “winding back the clock” to discover how and when a star blasted. The star in question exploded in the Small Magellanic Cloud a very long time ago. As you can guess, a stellar detonation is much l...

Hubble Pinpoints Supernova Blast Featured in this Hubble image is an expanding, gaseous corpse — a supernova remnant — known as 1E 0102.2-7219. It is the remnant of a star that exploded long ago in the Small Magellanic Cloud, a satellite galaxy of our Milky Way located roughly 200 000 light-years away. Because the gaseous knots in this supernova remnant are moving at different speeds and directions from the supernova explosion, those moving toward Earth are colored blue in this composition ...

Last Updated: How Old Are Supernovas?: NASA Astronomers Rewind Clock To Estimate Star Explosion Age “The victim is a star that exploded long ago in Small Magellanic Cloud, a satellite galaxy to our Milky Way," NASA astronomers studying supernovas age said. Researchers at NASA are rewinding the clock to calculate the age of the Supernova blast. NASAs Hubble Space Telescope captured an explosion of a nearby star, scientists are now trying to calculate an accurate estimate of the location a...
