A star in the Andromeda Galaxy has turned into a black hole without the characteristic explosion that usually accompanies such events 🌌

Scientists watched as the massive star disappeared, leaving behind only a cloud of dust.

To create it, photographer Aaron Jenkin travelled to Mount Cook National Park, New Zealand, known for its extremely low light pollution.

The two-stage Big Bang theory suggests that the initial explosion was followed by a second explosion leading to the origin of dark matter 💥

The possibility of detecting gravitational waves could provide evidence for these events and make significant changes to cosmological theory.

To get to Mars, spacecraft have to travel a much longer distance than the distance between Earth and Mars at the closest point of their orbits (about 55 million kilometres) 🚀 🚀

This is due to orbital mechanics, which requires proper trajectory and launch timing.

Scientists have found the youngest exoplanet 👶

🤯 Earth has rings!

They are much less visible than those of Saturn or Jupiter. These rings are made up of dust, small particles and micrometeorites that drift in the outer layers of the atmosphere.

How does a telescope work? 🔭

A telescope, like the eye, collects light from distant objects. However, the lens of a telescope is much larger than the pupil of the eye, so it can pick up more light. This allows the telescope to see objects that are too dim for the human eye.

The asteroid belt, located between Mars and Jupiter, contains most of the asteroids in the solar system and separates the rocky planets from the gas giants 🪐

The belt was originally thought to have formed from the shattered planet Phaethon. However, modern research has shown that it is a failed planet whose formation was disrupted by Jupiter's gravity.

Our galaxy - Milky Way 💫

The Earth's average temperature is 14°C, but without an atmosphere it would drop to -23°C, like the Moon.

The greenhouse effect created by Earth's atmosphere traps heat and makes our planet habitable.

💫 Introducing an incredibly detailed map of the Universe - the Laniakea supergroup!

This colossal supercluster of over 100,000 galaxies spans 500 million light years. One of its sections, marked in red, is home to our Milky Way galaxy.
