One of the biggest starfalls of the year awaits in November - EarthSky
The Leonids meteor stream will pass through the Earth's sky from 3 November to 2 December, reaching its peak on 18 November.
Meteors will be visible from nightfall until just before dawn
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.
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.
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).
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.
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.
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.
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.
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 Sun has reached its maximum activity in the current cycle - NASA.
Approximately every 11 years, the star's magnetic poles switch places and the Sun comes out of its quiescent state - the star's natural processes begin to have a greater impact on the operation of Earth's satellites, communication and navigation systems, radio, GPS and power grid.
Researchers suggest that the peak phase will last for about another year, after which the Sun will enter a decline phase.
Astronomers have discovered an ancient region in the Milky Way 12.5 billion years old 💫
This part of the galaxy, made up of ancient stars, has preserved a structure called "Pangu". It represents a remnant from an early stage of our galaxy's formation that absorbed and merged with other galaxies.
These ancient stars make up just 0.2 per cent of the Milky Way's mass. Their presence poses new mysteries for astronomers about the early history of our galaxy.
Scientists have reproduced the sound of a "magnetic upheaval" that occurred on Earth 41,000 years ago 👂
At that time, the planet's magnetic field lost 95 per cent of its strength, leading to an increase in cosmic radiation hitting the Earth.
This event may have led to the demise of megafauna and Neanderthals. With the help of modern technology, scientists have managed to reproduce the sound of this event, which sounds frightening.
🚀🗣 Starship has successfully launched in Texas: its Super Heavy launch vehicle was caught at the spaceport.
This is a huge step for mankind to conquer Mars, which will change astronautics in principle.
Upd: for those who didn't realise. Elon Musk has successfully attempted the first ever return to the launch pad and capture the Super Heavy booster.
The road to Mars is open.
The Earth's magnetic field is a giant invisible shield surrounding the Earth, protecting the planet from solar radiation.
The invisible forces extend from the Earth's poles thousands of kilometres into space.
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).
Computer modelling has shown that Mars' magnetic field existed longer than previously thought 🟠
Researchers studying large impact craters on the planet's surface have concluded that Mars lost its magnetic field later rather than 4.1 billion years ago.
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.
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.

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.
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.
Astronomers have discovered a black hole located 12 billion light-years from Earth, with a mass 17 billion times greater than the sun's 🌌 times the mass of the Earth
This black hole has an incredible appetite, consuming mass equal to the sun's every day.
If the Earth were in its gravitational field, it would be swallowed up in just 0.26 seconds.

At the Astronautics Congress in Milan, China presented a soil sample from the back side of the Moon ⚪️
It is 75 mg of regolith collected by the Chang'e-6 mission. This is the first time such a sample has been demonstrated outside China.
Studies have shown that the soil on the back side of the Moon is different from the soil on the front side.
Japanese satellites successfully conducted laser data exchange at record speed
The data transfer rate over a distance of about 40,000 kilometres was 1.8 gigabits per second.
The use of a repeater with the LUCAS optical communication system will increase the session duration from one hour to nine.
Earth, which we see from space as a blue planet, is actually not as rich in water as it seems. Water makes up only 0.12% of the total mass of the planet 🌍

From 2024 to 2038, the view of Saturn from Earth will gradually change 🪐
Changes in the mutual position of the planets in their orbits and the angle of rotation of the gas giant's rings will affect its appearance to Earth observers
