Inside of her head: it's a vast place.

She travels far and beyond.

But that has a supermassive blackhole as well. In the farthest corner of that place. It's tiny but dense.

She will reach for the stars, talk about anything and everything. Maybe sometimes, when she doesn't chase the stars, when she stays completely still and floats... the gravity starts to pull.

The pull is so strong that it takes her down the abyss where everything is dark.

The good thing is, she can see the polar star from that hole and that's gives her Hope!

She throws a lasso around that star and jumps right out of that abyss.

But sometimes, she's too tired. She is not depressed. She is sad.

Sometimes she thinks maybe sadness is the most real things in the universe, just like the darkness that lets the stars shine so bright and falls into a dilemma where she isn't sure anymore about what she loves more - the dark abyss or the bright stars 💫

 Which one is your favorite , comment below ... 1. NASA’s Viking I is the first ever spacecraft to touch the Mars surface. The Viking I spacecraft touched the martian surface on 20th July, 1976. This spacecraft also holds the record to send first ever image of Mars to Earth just after touching the surface of red planet. 2.The view of earth from space is the most spectacular things that a man ca ever get in his lifetime. NASA’s Saturn mission spacecraft manage to gift us view of mother Earth and Moon from Saturn. Cassini capture this color image of Earth and Moon from 900 million miles away just near to Saturn planet.  3..This spectacular view of Sunset on Mars was captured by NASA’s Spirit space rover.  4.Earthrise is the most popular photograph from NASA’s Polo 8 mission, the first ever manned mission to lunar orbit. Frank Borman, Jim Lovell and William Anders the astronauts of Apollo 8 mission took the photograph of mother planet from lunar orbit on Christmas evening of 24th December 1968. P.c.

What are white dwarfs?

Some curiosities about white dwarfs, a stellar corpse and the future of the sun.

Where a star ends up at the end of its life depends on the mass it was born with. Stars that have a lot of mass may end their lives as black holes or neutron stars.

A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula.

In 5.4 billion years from now, the Sun will enter what is known as the Red Giant phase of its evolution. This will begin once all hydrogen is exhausted in the core and the inert helium ash that has built up there becomes unstable and collapses under its own weight. This will cause the core to heat up and get denser, causing the Sun to grow in size.

It is calculated that the expanding Sun will grow large enough to encompass the orbit’s of Mercury, Venus, and maybe even Earth.

A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth. This makes white dwarfs one of the densest forms of matter, surpassed only by neutron stars and black holes.

The gravity on the surface of a white dwarf is 350,000 times that of gravity on Earth. 

White dwarfs reach this incredible density because they are so collapsed that their electrons are smashed together, forming what is called “degenerate matter.” This means that a more massive white dwarf has a smaller radius than its less massive counterpart. Burning stars balance the inward push of gravity with the outward push from fusion, but in a white dwarf, electrons must squeeze tightly together to create that outward-pressing force. As such, having shed much of its mass during the red giant phase, no white dwarf can exceed 1.4 times the mass of the sun.

While many white dwarfs fade away into relative obscurity, eventually radiating away all of their energy and becoming a black dwarf, those that have companions may suffer a different fate.

If the white dwarf is part of a binary system, it may be able to pull material from its companion onto its surface. Increasing the mass can have some interesting results.

One possibility is that adding more mass to the white dwarf could cause it to collapse into a much denser neutron star.

A far more explosive result is the Type 1a supernova. As the white dwarf pulls material from a companion star, the temperature increases, eventually triggering a runaway reaction that detonates in a violent supernova that destroys the white dwarf. This process is known as a single-degenerate model of a Type 1a supernova. 

If the companion is another white dwarf instead of an active star, the two stellar corpses merge together to kick off the fireworks. This process is known as a double-degenerate model of a Type 1a supernova.

At other times, the white dwarf may pull just enough material from its companion to briefly ignite in a nova, a far smaller explosion. Because the white dwarf remains intact, it can repeat the process several times when it reaches the critical point, briefly breathing life back into the dying star over and over again.

Wispy remains of a supernova explosion hide a possible ‘survivor.’ Of all the varieties of exploding stars, the ones called Type Ia are perhaps the most intriguing. Their predictable brightness lets astronomers measure the expansion of the universe, which led to the discovery of dark energy. Yet the cause of these supernovae remains a mystery. Do they happen when two white dwarf stars collide? Or does a single white dwarf gorge on gases stolen from a companion star until bursting? If the second theory is true, the normal star should survive. Astronomers used the Hubble Space Telescope to search the gauzy remains of a Type Ia supernova in a neighboring galaxy called the Large Magellanic Cloud. They found a sun-like star that showed signs of being associated with the supernova. Further investigations will be needed to learn if this star is truly the culprit behind a white dwarf’s fiery demise.

 This supernova remnant is located 160,000 light-years from Earth. The actual supernova remnant is the irregular shaped dust cloud, at the upper center of the image. The gas in the lower half of the image and the dense concentration of stars in the lower left are the outskirts of a star cluster.
