This is a new fanart made for the Iron Butchers warband (instagram: @enter.the.butcher) . The idea is a piece focused on the Iron Butchers vehicles. The centerpiece would be a Cauldron of Blood, a Khornate daemon-engine from the very old lore.

White dwarf devours pluto-like world, astronomers reveal cosmic feast
Astronomers have spotted a rare event where a white dwarf star consumed a pluto-sized world. this discovery offers a glimpse into the future of our own solar system and how stars interact with nearby planets in their final stages of life. a dramatic reminder of the powerful forces shaping the universe.
"We are the immortal heirs of the ancient realms, and we shall reclaim what was once ours."

Another Necron Warrior. I tried a bit different color scheme with more saturated bronze and turquoise black at the weapon (inspired by @warhipster ) . . . . #warhammer40k #40k #gamesworkshop #wargaming #warhammer #miniatures #abaddon #coolminis #eavymetal #whitedwarf #miniaturepainting #painting #art #miniaturephotography #photography #miniature #miniatureart #blacklegion40k #thearmypainter #tabletopgames #paintingwarhammer #chaosmarines #citadelpainting #vallejopaints #raphaelbrushes #necrons #necrons40k #szarekhandynasty #redgrassgames #contrastpaints #coolminis #photography https://www.instagram.com/p/CNVJyeknVQX/?igshid=yl20p3cgc8ov

For the people who don't know about white dwarfs, 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. Only the hot core of the star remains. . .

The Kepler space telescope has shown us our galaxy is teeming with planets — and other surprises
The Kepler space telescope has taught us there are so many planets out there, they outnumber even the stars. Here is a sample of these wondrous, weird and unexpected worlds (and other spectacular objects in space) that Kepler has spotted with its “eye” opened to the heavens.
Kepler has found that double sunsets really do exist.
Yes, Star Wars fans, the double sunset on Tatooine could really exist. Kepler discovered the first known planet around a double-star system, though Kepler-16b is probably a gas giant without a solid surface.
Kepler has gotten us closer to finding planets like Earth.
Nope. Kepler hasn’t found Earth 2.0, and that wasn’t the job it set out to do. But in its survey of hundreds of thousands of stars, Kepler found planets near in size to Earth orbiting at a distance where liquid water could pool on the surface. One of them, Kepler-62f, is about 40 percent bigger than Earth and is likely rocky. Is there life on any of them? We still have a lot more to learn.
This sizzling world is so hot iron would melt!
One of Kepler’s early discoveries was the small, scorched world of Kepler-10b. With a year that lasts less than an Earth day and density high enough to imply it’s probably made of iron and rock, this “lava world” gave us the first solid evidence of a rocky planet outside our solar system.
If it’s not an alien megastructure, what is this oddly fluctuating star?
When Kepler detected the oddly fluctuating light from “Tabby’s Star,” the internet lit up with speculation of an alien megastructure. Astronomers have concluded it’s probably an orbiting dust cloud.
Kepler caught this dead star cannibalizing its planet.
What happens when a solar system dies? Kepler discovered a white dwarf, the compact corpse of a star in the process of vaporizing a planet.
These Kepler planets are more than twice the age of our Sun!
The five small planets in Kepler-444 were born 11 billion years ago when our galaxy was in its youth. Imagine what these ancient planets look like after all that time?
Kepler found a supernova exploding at breakneck speed.
This premier planet hunter has also been watching stars explode. Kepler recorded a sped-up version of a supernova called a “fast-evolving luminescent transit” that reached its peak brightness at breakneck speed. It was caused by a star spewing out a dense shell of gas that lit up when hit with the shockwave from the blast.

This time-lapse, assembled from images taken by the Hubble Space Telescope over a period of two and a half years, shows the evolution of the light echo coming from the supernova SN 2014J.
The supernova was located in Messier 82, the „Cigar Galaxy“, about 3.5 mpc (11.5 million light-years) away from earth. The light echo is caused by light scattering of the interstellar dust cloud. When it was discovered in January 2014, it was one of the closest supernovae seen for decades and, due to its relative closeness and unusual brightness, of great interest for scientists and amateur astronomers.
The closeness of the supernova allowed astronomers to study it in much more detail than usual and might help us to understand how supernovae form and evolve. Moreover, SN2014J was, as its optical spectrum showed, a Type Ia supernova. These supernovae are used for determining distances in space, understanding them better may, therefore, help clarify the shape of the Universe.
A supernova is a large explosion that takes place at the end of a star's life cycle and produces heavier elements. When a supernova happens, the star expels all its, or at least a great majority of it, matter at speeds up to 10% the speed of light. In the case of SN2014J, the supernova produced a debris that originally expanded at up to 20,000 kilometres per second. The expelled matter can be seen as a supernova remnant.
Supernovae are classified according to their light curves, their absorption lines and the chemical elements they emit. If a supernova has a strong ionised silicon absorption line, it‘s a type Ia supernova; otherwise, it’s classified as Type Ib (this type has helium absorption lines) or Ic (doesn’t have helium absorption lines). The same classifications are used for type II supernovae. Type Ib, Type Ic, and Type II supernovae are the result of the core-collapse of a massive star.
A type Ia supernova occurs in a binary star system. Here, two stars are orbiting the same point. One of the two stars, usually a white dwarf, „consumes“ matter from its companion star. Due to this, the white star accumulates too much matter; its mass becomes greater than the Chandrasekhar limit, and this results in a supernova. The Chandrasekhar limit is the maximum mass of a stable white dwarf star, which is 1.4 times the mass of our sun. White dwarfs resist gravitational collapse primarily through electron degeneracy pressure. The Pauli exclusion principle disallows two electrons with the same spin to occupy the same energy state in the same volume. This forces them into higher energy states, once the lowest energy level is filled. When they are in a higher energy state, the electrons are travelling at faster speeds. These faster moving electrons create a pressure called electron degeneracy pressure. When the mass of the white star approaches the Chandrasekhar limit, its gravity attempts to squeeze the star into a smaller volume. This forces electrons into a higher energy state and therefore travelling at higher velocities. When the mass of the white dwarf is smaller than the Chandrasekhar limit, the electron degeneracy pressure in the star's core generates an equilibrium to the star's gravitational self-attraction, this prevents it from collapsing. At the Chandrasekhar limit, the electrons are travelling close to the speed of light, but the pressure exerted by them becomes insufficient to support the star, thus causes it to collapse and to evolve into a different type of stellar remnants, such as a neutron star or a black hole.
