Neutron stars, with a diameter not exceeding 10 km, can weigh as much as the Sun

The force of gravity is so high that if (hypothetically) an astronaut landed on it, his body weight would increase by one million tons!

What happens to metals in space?

In space, tightly compressed metals spontaneously weld due to the lack of oxides on their surfaces in the oxygen environment.

One year on Mars is almost twice as long as one year on Earth.

Its duration is about 687 days (1.88 Earth years).

The axis of Mars is tilted by 25.19 degrees with respect to the plane of its orbit. As a result, Mars has several seasons, but they are almost twice as long as on Earth because its orbital period is much longer.

Spring, in the northern hemisphere, lasts approximately 7 Earth months. Summer is second longest, lasting six months, while fall lasts 5.3 months and winter just over 4 months. In the southern hemisphere, the length of the seasons differs slightly.

Old infrared telescopes reveal secrets of nearby galaxies

NASA and ESA have published images of four galaxies close to the Milky Way. Their peculiarity is that they were derived from data from space telescopes that have already completed their mission.

The telescope was often unable to detect light from scattered clouds on the outskirts of galaxies. So the researchers supplemented its maps with data from three other "retired" space missions: Planck, IRAS and COBE.

The collaboration of four telescopes allowed scientists to obtain detailed infrared images of the Andromeda Galaxy (pictured), the Triangle Galaxy, and the Large and Small Magellanic Clouds.

The BepiColombo apparatus approached Mercury, the first planet of the solar system, for the second time

The minimum altitude of the close flyby was about 200 km, and the image below was obtained at an altitude of 920 km.

The Eye of Sauron

Oh yes, yes, even the legendary Sauron has been found in space!

That's the wonderful name of the star Fomalgaut, along with the space debris that surrounds it. Altogether it looks like a giant eye staring out of outer space. It is eternal and never blinks.

Space debris made of rocks, ice, and dust creates a giant disk around the Eye that is twice the size of the entire solar system.

The size of the star Aldebaran compared to the Sun

The Sun is shown in yellow. Aldebaran is an orange giant that is 65 light years away.

By the way, a light year is a unit of measure for the distance that light travels in a vacuum in one year. It is equal to 9,460,730,472,580,800 meters.

What is the link between the theory of relativity and GPS?

Einstein's theory of relativity predicts that time on the Earth's surface flows differently than on a higher orbit - the planet's gravity is weaker there. And the GPS satellites account for this difference!

On their high geostationary orbits time overtakes "our" time by as much as 38 millionths of a second per day. And the GPS needs 50 billionths of a second accuracy to work properly.

If the system didn't consider the theory of relativity, the GPS would "go away" by 10 kilometers per day and would be completely useless.

U.S. and Chinese satellites have staged an "orbital race

In December, China put a pair of Shiyan-12-01 and Shiyan-12-02 into orbit.

Shortly after Shiyan-12-01 and Shiyan-12-02 entered their target orbit, satellite spotters turned their attention to the maneuver performed by the U.S. USA 270.

It was launched in 2016 and is also an inspection satellite. USA was directed to intercept the Shiyan.

For a while, USA-270 approached a pair of Chinese satellites. Afterwards, they performed a counter maneuver, diverging in different directions.

The Eskimo Nebula

Here is a prime example of what awaits our Sun at the end of its evolutionary journey.

Yeah, one day our Sun will die, leaving behind a colorful planetary nebula that maybe someone will be able to observe from the outside.

What would happen to our Moon if the Earth were shaped like a doughnut?

Most likely, it would be pulled toward the hole, and it would bob up and down in the center of the planet.

Or it could be affected by the gravity of the outer edges of the doughnut to create an octagonal orbit around the Earth.

Amazing ancient star in the Milky Way

One of the oldest stars in the Universe, J0815+4729 is located within our Galaxy.

It has a surprisingly large amount of oxygen in its composition, an element that was not created at the time of the Big Bang, but appeared later as a result of nuclear fusion reactions in the bowels of the first generations of extremely massive luminaries.

Oxygen is the third most abundant element in the Universe after hydrogen and helium. It is necessary for all known forms of life and is a major component of the Earth's crust.

However, oxygen never existed in the young Universe, and tracing the history of its and other elements comes down to studying the oldest stars. J0815+4729 is one of them.

This fascinating illustration depicts various stars which probably have planets

The planets are shown as dark circles against the disks of their native stars, and the stars are arranged in descending order of size from the upper left to the lower right corner.

The stars and the planets intersecting their disks are displayed in the same stellar color scale. Of course, some stars are found to have more than one planet by transit, and you can look closely at this picture in higher resolution to spot them.

For comparison, here is the Sun - to the right and below the top row of stars. Its background features the silhouettes of Jupiter and Earth.

Astronomers saw the most powerful flash on Jupiter in the last 20 years

The flash resulted from the fall on Jupiter in October 2021 of the body with a diameter of 15 to 31 meters. The event lasted five and a half seconds, with the released energy equivalent to about two megatons in TNT equivalent.

A team of astronomers led by Ko Arimatsu of Kyoto University reported recording a new flare on Jupiter.

The event was recorded the afternoon of October 15, 2021 using ground-based 27-centimeter telescope PONCOTS, which conducted observations in the optical and near-infrared ranges.

What age do astronauts retire at?

Each astronaut retires when their health no longer allows them to fly or for personal reasons. No upper limit is set, it all depends on the individual astronaut.

Twenty-three years ago, 77-year-old American John Glenn proved that advanced age is no barrier to spaceflight. Since 1962, when Glenn was first on board the space shuttle, he has dreamed of flying again.

And on October 29, 1998, he finally made his dream come true. The gap between the astronaut's first and last flight was 36 years.

HE 0437-5439 is the most famous rogue star

It is moving away from the Milky Way at 723 km/s and has already traveled 200,000 light years away.

Its origin is still a mystery, but according to one theory, the triple star system experienced a close pass by the supermassive black hole Sagittarius A, located in the center of the Galaxy.

As a result, one of them was swallowed by the hole and the other two were thrown into intergalactic space by a powerful gravitational kick. The two soon merged into one massive star.
