Stellar life cycles

Excellent interpretation of gravitational interactions in our galaxy 💫

Humans are unable to feel gravitational waves, but we can process them so that we can hear them.

The Psyche spacecraft has separated from the upper stage of the Falcon Heavy rocket 🚀

Reaching asteroid Psyche will take 59 months and 3.6bn kilometres.

The James Webb telescope may have detected the first brown dwarfs outside the Milky Way in the vicinity of the Small Magellanic Cloud ☀️

These objects, too massive for planets but not massive enough for stars, number about three thousand in our galaxy. Studying these objects, 200,000 light-years from Earth, will provide a better understanding of star formation processes in environments other than the solar system.

Changes to spacecraft cabin design 🚀

The video demonstrates the significant distance between the Earth and the Moon ⚪️

The average distance is about 384,400 km, but it can fluctuate due to the elliptical orbit of the Moon.

At the minimum distance (perigee) The moon is 363,228 km away, and at its maximum (apogee) it is 405,400 km from Earth.

Saturn's rings, visible in the infrared spectrum, are significantly larger than those we observe in the visible range 🪐

Their size is twice the visible part. This suggests that the rings we see are only a part of the entire ring system.

Falcon Heavy rocket will launch the Europa Clipper mission 🚀

The mission aims to study Jupiter's satellite Europa, where there may be an ocean beneath the surface.

The AMS Europa Clipper is NASA's largest science probe designed for interplanetary exploration. The "Messages in a Bottle" campaign will send the names of 2,620,852 people recorded on a chip aboard the probe.

Visualisation of Earth's evolution over 4.5 billion years 🌍

Neptune's largest satellite, Triton, has an unusual retrograde orbit, that is, it moves in the opposite direction to the rotation of the planet 🔵

Triton is also home to icy volcanoes that spew out fountains of water and ammonia, forming impressive plumes. In addition to volcanoes, nitrogen geysers have been found on Triton.

Sunrise on Mars

How big would a meteorite have to be for it to completely wipe humanity off the face of the Earth? ☄️

According to scientists, a meteorite with a diameter of 100 kilometres could completely destroy us and leave us no chance of survival.

A flight to Mars takes about 9 months (about 270 days), provided the flight path is optimised to save fuel 🚀

This is possible because every 26 months, Earth and Mars come closer together, reducing the distance between them to 57 million kilometres (compared to a maximum distance of 401 million kilometres).

The James Webb Space Telescope has created detailed infrared images of 19 🛰 spiral galaxies

NASA believes these are the most detailed images of such objects to date. This new data will allow scientists to gain a deeper understanding of the formation of spiral galaxies.

The Universe is full of sounds that we can hear if we learn to perceive them 👂

For example, this is what a black hole 200 million light years away from us sounds like.

Observations of the Webb telescope have confirmed the hypothesis about the key role of stars like the Sun in enriching the Universe with heavy elements 🟠

Most of the elements in Mendeleev's periodic table are formed during the birth and death of stars. However, the bulk of these elements are found to emerge not from supernova explosions, but from the burnout of stars like the Sun.

Simulation of the supernova outburst SN 1054 🌟

The matter ejected into the surrounding space during the outburst formed the famous Crab Nebula. The outburst occurred in 1054 AD. Since then, the nebula has expanded to 11 light years in diameter. The expansion rate is 1500 kilometres per second (0.5% of the speed of light). By comparison, the fastest man-made object, the Parker Solar Probe, can reach a speed of about 192 km/s (0.064% of the speed of light).
