A star when alive and kicking, can literally be life-giver in its planetary system. Take for example the Solar System. The Sun created the planetary system, and endowed Earth with life itself. The planets peacefully revolve around the star and everything is somewhat alright.

But astronomers have now observed a dead star who is involved in what is being called 'cosmic cannibalism. The dead star is ripping apart its own planetary system.

The star is called G238-44. It is a White Dwarf star. Normal star the size of our Sun, on completion of its life, becomes a White Dwarf.

However, prior to becoming a White Dwarf, such star becomes Red Giant. In this phase, it expands rapidly and disrupts orbits of the planets revolving around it. This sends them on a haywire path.

What's happening, in this case, is that the planets are disintegrating due to the tidal forces of the White Dwarf. The result is total chaos with planetary material falling onto the White Dwarf star.

We may get to witness this cosmic process from afar but 5 billion years in future when&nbsp;the Solar System will meet the same fate.

"When a star like our Sun expands into a bloated red giant late in its life, it will shed mass by puffing off its outer layers. One consequence of this can be the gravitational scattering of small objects like asteroids, comets, and moons by any remaining large planets. Like pinballs in an arcade game, the surviving objects can be thrown into highly eccentric orbits," says NASA on its website.

"...5 billion years from now. Earth might be completely vaporized along with the inner planets. But the orbits of many of the asteroids in the main asteroid belt will be gravitationally perturbed by Jupiter and will eventually fall onto the white dwarf that the remnant Sun will become."

A dead star is ripping apart its planets in 'cosmic cannibalism'

Are we alone in the universe? This is a question that has bothered scientists for time immemorial. A number of researchers over the years have attempted to find any trace of alien life in the farthest corners of the universe but till now, no concrete proof has emerged from the studies. However, according to a professor at the University of California Los Angeles, there can be intelligent alien life on Dyson spheres around white dwarf stars in the Milky Way. Ben Zuckerman, who teaches physics and astronomy, has authored a new study which focuses on alien presence in the Dyson spheres.

Dyson spheres are hypothetical constructions which exist around a star and the spheres, named after well-known physicist Freeman Dyson, take in a huge amount of the star’s power output.

According to the study, Freedom suggested that if alien life exists on a planet, they would prefer to create a Dyson sphere around their star than moving around in the universe. As a result, a study of the spheres can point towards the viability of alien life on a white dwarf (a small, dense star).

The study proposes that Dyson spheres can also allow the scientists to understand the exact number of alien civilisations that exist in the universe. The absence of any Dyson spheres can hint at an unstable environment and that rules out the presence of alien species up to a certain extent.

While the suggestions are new because of the lack of data about white dwarves, this can be an incomplete solution as the Dyson spheres does not have a straight correlation with life till now.

Can there be alien life in Milky Way? New study provides a fascinating answer

A dead star has officially smashed the record for the fastest known spin rate of a white dwarf.

Located over 2000 ight years away, the wild 'propellor' star is called LAMOST J024048.51+195226.9.

The research, published in the Monthly Notices of the Royal Astronomical Society: Letters, shows that the star's speed has broken the previous record by 29 seconds.

Plasma is getting flung out at 3000 km/second from the star which resembles AE Aquarii.

According to astrophysicist Ingrid Pelisoli of the University of Warwick in the UK, ''the star will have completed several rotations in the short amount of time that people take to read about it, it is really incredible.''

''The rotation is so fast that the white dwarf must have an above average mass just to stay together and not be torn apart.''

''It is pulling material from its companion star due to its gravitational effect, but as that gets closer to the white dwarf the magnetic field starts to dominate. This type of gas is highly conducting and picks up a lot of speed from this process, which propels it away from the star and out into space,'' he added.

In their death throes, roughly 97 per cent&nbsp;of all stars become a smoldering stellar zombie called a white dwarf, one of the densest objects in the cosmos.

Only two other types of objects,&nbsp;black holes and neutron stars,&nbsp;are more compact than white dwarfs.

Stars with up to eight times the mass of our sun are thought to be destined to end up as a white dwarf.&nbsp;

Such stars eventually burn up all of the hydrogen they use as fuel through nuclear fusion. At this point, gravity causes them to collapse and blow off their outer layers in a 'red giant' stage, eventually leaving a dense core that is a white dwarf.

White dwarfs initially have high temperatures but gradually cool over time, lacking any new energy source.

In appprocimately 5 billion years, our sun is expected to become a red giant and later a white dwarf.

Dead star breaks record for fastest known spin rate of white dwarf

Earth rotates around itself once a day. For Sun this duration is of 1 month. Other planets in our solar system have varying durations. But a single rotation in 25 seconds? That's some serious speed for a celestial body.

A white dwarf star has been found to perform this extreme space ballet. The star is named (rather heartlessly it would appear), LAMOST J0240+1952. It is 2000 lightyears away from Earth.

It is a white dwarf star. These stars are extremely dense. The star has size of Earth but has mass equal to the Sun. So much material packed in such a small space makes the surface gravity of the star ridiculously extreme. If a pebble is lifted from the surface of the star and dropped from a mere few feet, it would collide with the surface of the star at a speed equal to thousands of miles an hour! The white dwarf is located in Aries constellation.

The massive rotation rate of this star was discovered on August 7 by astronomer Ingrid Pelisoli of the University of Warwick in Coventry, England. She and her team noticed a particular 'blip' from this star. The blip came every 25 seconds. It was subsequently found that the blip is due to rotation of the star around itself.

A red dwarf was found to be revolving around the white dwarf. The red dwarf is the reason why the white dwarf has such a mind boggling speed of rotation.

The death of the first known exoplanet to survive the death of its star provides a glimpse of the solar system's future, as per a new study.

Researchers have discovered a huge snowman-shaped star with a unique atmospheric composition.

The enormous white dwarf star is known as WDJ0551+4135 and is thought to have resulted from the merger of two so-called white dwarf stars that often explode as powerful supernovas.

Usually, they're small and lightweight but this star is 1.14 times the mass of our sun which is nearly twice the average mass of a white dwarf star.

"This star stood out as something we had never seen before," said Mark Hollands, lead study author and postdoctoral researcher at the University of Warwick's department of physics.

''Initially, these observations didn't make any sense. The only way you can explain it is if it was formed through a merger of two white dwarfs," he added.

Astronomers first spotted the star in data collected by the European Space Agency's Gaia space telescope, launched in 2013.
