NASA detects gigantic “bullets in gun” in the space – The Universal

Hubble space telescope NASA has detected a super-hot “cannon balls” coming out of a dying star, who has left intrigued scientists about the origin of these giant balloons of gas.

The fireballs are twice the size of Mars, and are traveling so fast, that it would only take them 30 minutes to travel from the Earth to the Moon, according to data from the website of Hubble. Its surface temperature is 17-thousand degrees Fahrenheit (9.427 or C), making it nearly two times hotter than the surface of the Sun.

balls of fire represent a puzzle for astronomers, since the material ejected could not have been fired by the parent star, called V Hydrae. The star is a red giant puffy, localized to a thousand 200 light years away from Earth, which has probably been stripped of at least half of its mass into space during its death throes.

The best explanation suggests that the balls of plasma were launched by a companion star invisible. According to this theory, the partner would have to be in a elliptical orbit that takes you close to the atmosphere squeezing the red giant every 8.5 years. As the companion enters the outer atmosphere of the star fans, who gobbles up material. this material settles into a disk around the companion, and serves as a launching pad to spots of plasma which travel at about half a million miles per hour.

This star system could be the archetype to explain a dazzling array of shiny forms discovered by the Hubble that you see around the dying stars, called planetary nebulae, say researchers. A planetary nebula is a shell extension for the gas that shines brightly and is expelled by a star at the end of its useful life.

“we Knew that this object had a high-speed output by the above data, but this is the first time that we see this process in action,” said Raghvendra Sahai of the Jet Propulsion Laboratory of NASA in Pasadena, California, lead author of the study. “We suggest that these bubbles of gas produced during this late phase of the help to the life of a star that the structures observed in planetary nebulae”.

The Hubble observations in the last two decades have revealed an enormous complexity and diversity of the structure of planetary nebulae. The telescope high-resolution has caught knots of material in the clouds of gas that glow brightly and surrounding the dying star.

The astronomers speculate that these knots are, in reality, the jets driven by disks of material around stars companions that were not visible in the Hubble images. Most of the stars in the Milky Way are members of binary systems. But the details of how they produced these jets remains a mystery.
