if a black hole were a person 🕳️🚀
this was one of the best decisions to make breasts. Now it looks perfect in a swimsuit.
No, not silicone, it's my own fat and the shape has been slightly corrected.
While orphan planets don't orbit stars, they still move freely in interstellar space under the influence of gravity. These planets are like cosmic wanderers that follow no rules.
They are detected using gravitational microlensing:
Sometimes the trajectory of an orphan planet takes it between Earth and a distant background star the pic). When this cosmic lone wolf crosses paths, its gravity bends the light from the background star, temporarily increasing its brightness. It's as if the universe is saying: "Hey, look at this drifter!"
This cosmic photobombing lasts from several hours to several days until the orphan planet passes out of sight. Such coincidences are rarer than finding a clean public restroom, so astronomers observe millions of stars simultaneously, hoping to catch these interstellar rebels.

Orphan planets are planetary objects that don't orbit a star, but rather drift through space. They could have been ejected from their star systems or formed independently. These planets don't have stars (that’s why they are orphans, everything is like people😁), move freely in interstellar space and come in different sizes: from small to gas giants. Due to the lack of a nearby heat source, they are usually very cold (a star always provides warmth, just like parents do for children). Orphan planets can form by gravitational ejection from a star system, the disintegration of binary star systems, or formation from interstellar gas and dust without a star formation step.
Next time I’ll tell you how they are discovered, it’s not easy
I really didn't know about it!
Next time I will tell you😌
I'm sorry really, but I have family problems now. My grandma has sarcoma and it beats me a lot, no time even for myself.
Well...it's possible, but...haha)
Planet formation begins with the formation of a protoplanetary disk around a young star. This disk is made of gas, dust and ice. Planets form by accreting material from this disk. However, the accretion process is not uniform due to differences in material distribution, density, temperature and pressure in different regions of the disk.
For example, one planet may form closer to the star and be composed primarily of silicates and metals, while another may form further away and contain more ice and gases.
Planets are influenced by external factors, such as gravitational interactions with other bodies in the system or the effects of young stellar winds and radiation.
Because of these reasons, each planet is a unique object with its own structure, composition and characteristics. This makes the probability of the formation of two exactly identical planets extremely low.
On the pic you can see the formation of the host star and planets around it from protoplanetary disk.

The large-scale structure of the Universe includes galaxies that form clusters, and clusters form superclusters. These structures form giant threads of the web of galaxies and gas .
Until recently, we thought that galaxy clusters were the largest "structures" in the Universe. But if, as in the figure below, we imagine that each galaxy corresponds to one point, then we will see the “web”.
There are practically no galaxies inside the holes of this web. All of them are located on the threads of the web. Voids (emptiness) are the largest structural formations in the Universe.
On a scale of >300 million light years(for example the size of a Galaxy ~1000 light years), the Universe is homogeneous and isotropic, which means that when looking at a piece of a web of this size from one place and from another, the amount of matter in these two pieces will be ± the same.
That is, the large-scale structure of the universe is a beautiful, almost symmetrical giant web:)
Ask questions, the topic is complex,
I will be glad to answer😌

In fact, the Earth revolves around the Sun, and the Sun, in turn, moves around the center of the Milky Way galaxy. And then this center of the galaxy also interacts with other galaxies in the Universe.
Further, our knowledge about the structure and movement of the Universe is not so cool and predictable:)
There are hypotheses about the movement of galaxies in the large-scale structure of the Universe, but the exact answer to the question of what the center of the galaxy or galaxy clusters moves around requires further research and observation.
P.S. The large-scale structure of the universe is, roughly speaking, a collection of large objects. Galaxies and all that. I'll tell you about this next time)
As stars evolve, they produce energy through nuclear fusion of elements, ranging from light elements such as hydrogen to heavy elements such as iron.
When a star runs out of fuel, it can explode as a supernova, throwing its shell and created elements into space. These elements can then recombine to form new stars, planets and even life.
So, we are children of stars:)
I won’t congratulate you on March 8th, there are only guys here :) I just want to say that girls can do anything.
And do physics and be sexy and
even both at the same time😌
In fact, physicists today are not as canonical as they were two centuries ago. We rarely write on paper and mostly write code and make graphs. We analyze and count through code and programs.
We remember only basic things about physics and often use books to refresh our memory and remember how to calculate this or that integral.
and the most interesting thing is that I recently caught myself not remembering a long division)))
What do I think about zodiac signs and why do I joke about this topic quite often on Instagram?
Astrology is considered a pseudoscience and has no evidence base.
In 1948, psychologist Bertram Forer conducted an experiment in which he gave personality tests to students and gave each one the same vague text from a horoscope, presenting it as an individual personality analysis. Students were then asked to rate the accuracy of the description. The average rating was high, indicating that people often rate the accuracy of such generalized descriptions presented to them as individual ones. Subsequently, the experiment was repeated many times with the same result [1]. This effect particularly explains the popularity of astrology and other pseudosciences.
That is, in essence, our brain is simply fooling us😁
And yes, aquarius sign is so skeptical😏
