Into the Void: The Coldest, Most Isolated Spot in the Universe
When you reach the coldest point in the cosmos, you realize that even the Universe has its silent, frozen limits How cold is space? Although the universe is filled with a vast number of stars that emit heat, the distance between them is quite large. Usually, the temperature in outer space does not fall below…

Staring Into The Depths Of Time: The Oldest Galaxies Ever Discovered
In the light of old galaxies, we glimpse the first chapter of the cosmos. Studying very distant galaxies allows astronomers to understand the processes that took place in the Universe during the first hundreds of millions of years of its existence. The oldest galaxy discovered so far is JADES-GS-z14-0. JADES-GS-z14-0 was discovered in 2024. We…

The Death of Everything: The Universe’s Final Journey
The end of the Universe is not a tragedy, but a natural conclusion of its story The future of the universe depends on its physical properties: mass, energy, average density and expansion rate. The following development options exist: Big Rip, Big Crunch, Heat death (also known as the Big Freeze). There is also a hypothesis…

Beyond Our Blue Planet: Are We Alone in the Universe?
The universe is a pretty big place. If it’s just us, it seems like an awful waste of space. Is there life in the universe? Many scientists no longer ask this question, but ask another, more specific one – when will we discover it? According to modern estimates, the probability of the existence of the…

Eternal Cosmic Inhabitants: Neutron Stars And Their Marvels
The heartbeat of the cosmos beats in neutron stars A neutron star is a cosmic body that represents the final stage of the evolution of stars. This star has a mass comparable to that of the Sun and is compact in size – their typical radius is only 10-20 km. Despite this, they have an…

The Loudest Voices in the Universe: The Fascinating World of Radio Galaxies
Signals in the cosmic silence: the profound voice of radio galaxies; cosmic giants broadcasting across the universe Radio galaxies are galaxies that are characterized by powerful radio emission. These are usually large massive galaxies with a dense region in the center – the core. Radio galaxies belong to a separate group of space objects, although…

From Quasars to Cosmos: A Journey into the Heart of Distant Galaxies
Quasars are windows into bright and terrible wisdom Quasars are a rare class of space objects that are characterized by very high luminosity and huge energy emissions. For example, a supernova explosion is considered one of the most powerful energy emissions in the entire Universe, but a quasar would need no more than 30 minutes…

Supernovae: Nature’s Brilliant Stellar Explosions Explained
You know what a supernova is? It’s a dead star. And yet, it is the most beautiful specimen in the universe. A supernova is a special type of star that ends its life with a bright explosion, which releases a huge amount of energy and leaves behind beautiful nebulae. Simply put, it is a powerful…

Pulsars: The Fast-Spinning Neutron Stars
the most likely explanation is that pulsars are evidence of post-Singularity, astroengineering of a magnitude our pre-Singularity minds simply cannot imagine Pulsars are weak sources of cosmic radiation, bursts of which follow each other with a very slowly changing period. The central body of the pulsar is a neutron star with a radius of about…

Mystery of Dark Matter & Dark Energy
Dark matter and dark energy are two things we measure in the Universe ther are making things happen, and we have no idea what the cause is All the visible matter in the Universe is only a small part of what our world consists of. Most of the space is actually occupied by dark matter…

Exploring interstellar travel through wormholes
On the other side of a wormhole there could even be a big bang Wormholes are the most intriguing objects in the Universe, the existence of which is debated by scientists The hypothesis that there may be “tunnels” in the structure of space-time that allow instantaneous travel over vast distances, time travel, or travel between…
