Studies of 69 nearby galaxies have shown that the mass of a black hole affects the growth of a galaxy 🌌

Before the Big Bang, there was nothing 💥

According to Stephen Hawking, if this were true, the universe "would have been neither created nor destroyed. It just would have been." The scary part: if there was nothing before the Big Bang, how long did it last before the universe came into existence?

What do solar eclipses look like on other planets? 🔅

It all depends on the size of the satellite and its location above the planet's surface. We are lucky: we can observe both a total eclipse and a partial, annular eclipse.

But Mars has satellites so small that even its largest satellite, Phobos, is unable to cover the entire Sun.

The video shows the Martian eclipse captured by Curiosity.

NASA showed what happens if you get inside a black hole 🛰

The process of getting into a black hole has been called "spaghettification". The object is stretched like a noodle during the interaction.

The simulation is created in two views. In one, the camera shows the approach to a supermassive black hole, spiral around it and cross the event horizon. This is the zone of no return, which nothing can leave. In the other case, a conditional traveller approaches the event horizon but does not cross it.

It took the supercomputer over 5 days to create this video, on a normal laptop it would have taken 10 years.

Map of asteroids in the solar system 🪨

The map shows the orbits of more than 18 thousand asteroids. About 10 thousand of them have a diameter of 10 kilometres or more.

Arizona-based amateur astrophotographer Andrew McCarthy has revealed a 5-hour timelapse of the Sun. Hard to believe, but he shot these mesmerising images from his front lawn.

A computer model shows the distribution of objects in close proximity to the Earth 💫

According to NASA, 95 per cent of them are space debris and the remaining 5 per cent are active satellites, small asteroids and other objects

The Doppler method is one way to detect exoplanets 🪐

It is based on observing the change in the colour of a star's light caused by the gravitational influence of a planet orbiting around it.

Gravitational lensing is a phenomenon in the Universe in which the gravity of massive objects bends and amplifies light from objects behind them ☀️

This allows scientists to observe very dim objects, such as stars and planets, at great distances - millions or even billions of light years.

Cosmic Question ❓

The Webb telescope has captured a galaxy whose image is distorted by a gravitational lens created by a cluster of galaxies. This photograph is not only unusual in shape, but also important for studying cosmic evolution.

The launch of the EscaPADE mission, organised by NASA, has been postponed 🚀

The EscaPADE mission includes two probes developed by Rocket Lab that are designed to study the magnetosphere and atmosphere of Mars.

The postponement of the launch is due to the limitations of the ballistic window for a mission to Mars, which is narrow and does not allow for flexible launch planning.

Tourists went into outer space for the first time thanks to the SpaceX flight. The first to leave the ship was billionaire Jared Isaacman, followed by company engineer Sarah Gillies.

The crew climbed to an altitude above 700 kilometres from Earth - that's twice as far beyond the ISS orbit. Crew members will test spacesuits with projection displays.

Venus looked almost exactly like Earth does now, about two billion years ago 🟡 .

Today, Venus is a living hell. It has a stifling atmosphere of carbon dioxide and almost no water vapour; temperatures reach 462 degrees Celsius! But climate modelling has shown that ancient Venus may have had oceans and land, just as Earth did
