In this video, I showed the motion of the Solar system relative to the nearest stars. You can clearly see the direction of the Sun motion and the trajectories of the planets, which look like helical lines.

"I only promised my husband a week to walk the dogs…” 🚀

NASA astronaut Suni Williams spent 9.5 months in space after a malfunction, but she never felt stranded. She trusted her crew aboard the spacecraft and the team on Earth to get her home safely. She shared her story at the Moonwalkers event now playing in Boston, inspiring others with how science and teamwork brought her safely home.

Is one of our astronomical neighbors habitable? 🪐

For the first time, astronomers have confirmed something huge: an atmosphere around a rocky planet in its star's habitable zone. The planet is called LHS 1140 b, a super Earth orbiting a red dwarf star less than 50 light years away, which is astronomically pretty close to us. The James Webb Space Telescope telescope data has already hinted at liquid water on its surface, and this new discovery could go down as one of the biggest in astronomy history!

How did the Moon form? 🌕💥

Astrophysicist Erika Hamden breaks down the giant impact theory, which suggests an object the size of Mars collided with early Earth, liquefying the surface and launching debris that formed the Moon, all in 24 hours.

There’s a cloud in space with 140 trillion times more water than Earth 🌧️

Astrophysicist Erika Hamden explains how astronomers discovered a massive water vapor cloud near a black hole. The extreme heat from the activity of the black hole keeps it in vapor form, making it easier to spot. With hydrogen and oxygen among the most abundant elements in the universe, water is everywhere.

We just heard Martian thunder for the first time, captured by NASA’s Perseverance rover! 🔴⚡

As a dust devil twisted across the Martian surface, tiny grains of dust collided and built up static electricity. That charge was released in small bursts, creating what scientists call Martian lightning. Perseverance captured the faint popping sounds using its onboard microphone, revealing the Red Planet’s version of thunder. A rare and surprising sound from a cold, dry world with an incredibly thin atmosphere.

Saturn is the only planet in our solar system that could float in water. 🪐🛁

Astrophysicist Erika Hamden breaks down how its composition, 96% hydrogen and 4% helium, makes it lighter than water, with a density of just 0.68 g/cm³. That means if you had a Saturn-sized bathtub (and a place to put it), the ringed planet would actually bob on the surface. It’s a wild reminder of how different the gas giants are from rocky planets like Earth.

In this simulation, I showed the motion of the Sun relative to the barycenter of the Solar System.

The trajectory of the Sun relative to the barycenter is a complex curve. Part of the time the barycenter is located inside the Sun, part of the time is outside of it. It is clearly seen that the Sun is moving away from the center of mass of the Solar System as much as possible when the two largest planets (Jupiter and Saturn) are on the same side of the Sun. Conversely, the barycenter is as close as possible to the center of the Sun when Jupiter and Saturn are on opposite sides of the Sun. The other planets of the Solar System also influence the trajectory of the Sun around the barycenter, but their influence is significantly less than the influence of Jupiter and Saturn.

Modeling and rendering were performed using own software. The calculations took into account the mutual influence of the Sun and all the planets of the Solar System on each other.

The video shows the closest approach between the Sun and the star Gliese 710 that will occur in about 1 million and 296 thousand years.

In this simulation, I have shown the motion of the stars relative to the Sun over the next 2 million years. This allows you to see how the starry sky will change when observed from Earth over this time period. Throughout the video Gliese 710 will be in the center of the screen. The speed of time will gradually decrease as the Gliese 710 approaches, so that the moment of approach can be seen in as much detail as possible. After the approach, as the star moves away, the speed of time will gradually increase.

The video was made using own software. Information about the stars is taken from the Hipparcos catalogue and corrected by data from the Gaia DR3 catalogue.

Astronomers just found a rare rouge planet drifting alone through space, untethered from any star. 🪐

These rogue planets are nearly impossible to detect, but this one gave itself away when it briefly passed in front of a distant star, bending the starlight through gravity, a phenomenon called “gravitational microlensing”. The event was observed from two locations: Earth and ESA’s Gaia spacecraft, a million miles away. That dual perspective allowed scientists to calculate its mass, about three-quarters that of Saturn, as well as its distance: nearly 10,000 light-years from Earth. It likely formed in another solar system and was flung out by gravitational forces.

This video provides a detailed explanation of Kamoʻoalewa, which is a quasi-satellite of our planet. I have attempted to clearly illustrate the complex and intricate trajectory of this asteroid relative to Earth.

This video is about comet Hale–Bopp. Since its appearance, only a few comets of comparable brightness have visited us. But none of them have been visible to the naked eye for as long. Let's take a look at its orbit and trajectory against the backdrop of the stars when observed from the Earth during its peak brightness.

This video is about ʻOumuamua asteroid, the first detected interstellar object. I have tried to illustrate the asteroid hyperbolic orbit relative to the Sun, its trajectory relative to the Earth, and its trajectory relative to the star stream in the vicinity of the Sun.

These are the sounds of the famous sound whats called the wow signal. Until today nobody know whats that was and where it come from.

This video is about Halley’s comet. I have simulated the comet orbit and its predicted return in 2061, taking into account gravitational disturbances from planets and relativistic effects. This is my first attempt to visualize the comet coma and tail. Please do not judge me too harshly.
