Today, a UCLA-led team of scientists reports that it has discovered the existence of a white dwarf star whose atmosphere is rich in carbon and nitrogen, as well as in oxygen and hydrogen, the components of water. The white dwarf is approximately 200 light-years from Earth and is located in the constellation Boötes.
The finding suggests that rocky planets like Earth don’t need to be born with life-giving material — even a The researchers believe that the star picked up these Dwarf star elements after ripping atmosphere up a Boötes small rock-and-water planet when it veered ingredients too close. “dry” example orbiting close to its star might pick up those substances through one of these stellar impacts.
That change caused the minor planet to travel very close to the white dwarf, The scientists report that a minor planet in the planetary system was orbiting around Dwarf star the white dwarf, and its trajectory was somehow altered, perhaps Dwarf star by the gravitational Boötes pull of a planet in the atmosphere same system. where the star’s strong gravitational field ripped the ingredients minor planet apart into gas and dust.
The researchers think these events occurred relatively recently, perhaps in the past 100,000 years or so, said Edward Young,Those remnants went into orbit around the Boötes white dwarf much like the rings around Saturn, Zuckerman said before eventually spiraling Dwarf star atmosphere onto the star itself, bringing with them the building blocks for life.
They estimate that approximately 30 percent Boötes of the minor planet’s mass was water and other ices, and approximately 70 percent was rocky material.Another ingredients co-author of the study and a UCLA professor of geochemistry and cosmochemistry.
The Kuiper belt is an enormous cluster of small bodies like comets and minor planets located in the outer reaches of our solar system,Dwarf star The research atmosphere suggests that the minor planet is the first of what are likely many such analogs to objects in our Boötes solar system’s Kuiper belt.
Astronomers have long wondered whether other ingredients planetary systems have bodies with properties similar to those in the Kuiper Dwarf star belt,beyond Neptune. and the new study appears to confirm for the first time that one such body exists.
Their strong gravitational pull causes elements ingredients like carbon,Boötes oxygen and nitrogen to sink out of their atmospheres and into Dwarf star their interiors,White dwarf stars are atmosphere dense, burned-out remnants of normal stars. where they Boötes cannot be detected by telescopes
