Have you seen anything that strong before ?

2022-05-28 10:00:05 Will the Sun ever become a black hole? No, it won't and never will.

Why?? Because the sun is way, way too small and has way, way too little mass.

Our sun is referred to as a type G Dwarf star. Stars like the sun will fuse hydrogen into helium and then helium into carbon and a little oxygen. After that, it's essentially the end of fusion for the star.

The best the sun can hope for at the end of its life is to finally become a white/black dwarf which is one of three outcomes for all stars.

This video shows the astronaut's work in the neutral buoyancy laboratory – this is a huge pool in which full-size models of the ISS working modules and spacecraft are located.

It is here that astronauts train to perform various jobs in spacesuits and conditions close to zero gravity.

2022-05-27 10:00:05 Yes, there is something in space called The Great Attractor!

It was discovered in the 1970s.

The view of The Great Attractor is obscured by our own Milky Way's galactic plane. It would take 100 million years for the milky way to rotate and give us a view.

As the name suggests, The Great Attractor is attracting.

It could be 250 million light-years away.

Observations of galaxies reveal that they are slightly drawn toward this anomaly based on variations in their redshifts.

As x-ray astronomy became more powerful, scientists could start to see through the Milky Way. There are two galaxy clusters, the Norma Cluster and Shapley Supercluster which could also be tugging on local galaxies.

So as we hurtle through the cosmos, the Great Attractor, despite its glorious title, could in fact be a perfectly normal collection of galaxies, which just happens to be hidden from us.

2022-05-26 10:00:06 Scientists have seen the explosion of a white dwarf for the first time

The flare was classified as a classic nova and occurred in a cataclysmic variable of the Sculptor type VY, which contains He/N-a white dwarf and is located at a distance of 8.2 thousand light-years from the Sun.

The flash of X-ray radiation began 11 hours before the nine-fold increase in the brightness of the nova in the optical range and lasted less than 8 hours. At the same time, the flare spectrum can be described by a model of the atmosphere of a white dwarf heated to 327 thousand kelvin, and the mass of the dwarf was estimated at 0.98 solar masses, which is quite a lot. Thus, the existence of X-ray flashes is now confirmed observationally

At first glance, you can't tell that this is something extraterrestrial.

Immediately after landing, they can't stand on their feet at all.
