💫 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.

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 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.

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.
The brightest galaxy known to us has been found with the WISE✨ telescope
To say that WISE J224607.57-052635.0 is glowing is to say nothing - it shines like 300 trillion солнц☀️
The supposed cause is a black hole of such gravity that it's hard to imagine its existence. It has long ago exceeded its absorption threshold and is spewing energy into the surrounding dust cocoon, generating a glowing aura.
Incredible timelapse from the ISS by Matthew Dominick, which answers two popular questions at once: why can't you see the stars and where are the satellites? ✨

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.

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.
🤯 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.
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.
A timelapse of the Milky Way
To create it, photographer Aaron Jenkin travelled to Mount Cook National Park, New Zealand, known for its extremely low light pollution.

James Webb has discovered many supernovae in the early Universe ✨
The scientists estimate that 10 times more supernovae have been identified than were previously known. Before the study, only a few such objects had been found in the early Universe with redshift values greater than Z=2, which corresponds to a Universe age of just 3.3 billion years. Now JWST has observed many supernovae that erupted when the Universe was less than 2 billion years old, including a previously known and spectroscopically confirmed supernova with Z=3.8, which is when the Universe is only 1.8 billion years old.
To detect supernovae, the team compared several images taken one year apart and looked for sources that disappeared or appeared. Such objects, whose brightness changes over time, are called transient objects. In total, the team found about 80 supernovae in a patch of sky the size of a grain of rice
