Flag of the Earth
Before the astronauts landed on the moon, there was an opinion that the first people on the satellite should leave there not an American flag, but a flag representing all of humanity. And although these few voices were not heard, in 1970 they pushed James Cadle, who lived on a farm in Illinois, to create…

The Leo Triplet Galaxy Group
The Leo Triplet Galaxy Group is three galaxies in one field of view. This group includes huge spiral galaxies: NGC 3628 (left), M66 (bottom right) and M65 (top). Their galactic disks are tilted at different angles to the beam of our vision. NGC 3628 is visible from the edge, and light-absorbing dust bands intersect the…

NASA astronomers have discovered a “hellish” planet that continuously burns and emits lava flows
NASA has discovered the planet 55 Cancri e 50 light-years from Earth. It is too close to its star, which is why it constantly burns and emits lava flows. The conditions on the planet were compared to hell. The temperature of the planet is several times higher than the melting point of metals, so huge…

NASA has commissioned Collins Aerospace and Axiom Space to develop a new generation of spacesuits
The new generation spacesuits are planned to be used on the ISS, as well as in the Artemis lunar program. The new spacesuits will allow astronauts to go into outer space in low Earth orbit from the ISS, as well as explore the lunar surface. Upon completion of the development, the spacesuits will remain the…

NASA conducted exercises on planetary defense
Coordinated by the International Asteroid Warning Network and the NASA Planetary Defense Coordination Office, the exercises confirmed that the detection of an asteroid and the establishment of its characteristics by the international community takes place promptly. This makes it possible to identify and assess the danger that these objects pose when approaching the Earth. Last…

Astronomers announced the discovery of the oldest known quasar, it received the designation J0313-1806
Its redshift is z=7.642. This means that we see J0313-1806 as it was at the time when the universe was 670 million years old. Quasars can emit a thousand times more energy than galaxies like the Milky Way. The source of all activity is accretion disks and jets of supermassive black holes that are in…

Can the universe be infinite?
The universe can be infinite. But it may not be. We don’t know the final answer yet. To date , the following is known: — When it comes to the size of the universe, they mean the observable universe. It is not identical to the universe at all. We can observe the universe only from…

The mystery of an unknown space object has been revealed
An international team of scientists has revealed the mysterious nature of the object PSR J2039−5617. It turned out that in the center of an unknown cosmic source of X-ray and gamma radiation is a pulsar that rotates around an evaporating star. In the system, the pulsar heats up one side of the satellite star, which…

Mitsubishi Electric has developed a technology that will allow printing satellite dishes in space
Antennas for spacecraft communication systems are one of the few things in the industry for which “size matters”. After all, it is the size of the antenna that primarily determines its gain, radiation pattern and other parameters that ultimately affect the very possibility of communication or observation. The bigger the antenna, the better it is.…

Why has man never flown to the dark side of the moon?
The answer, in fact, is simple: there is no radio communication with Earth on the other side. This problem can be solved by grouping satellites that will forward the signal, but it is expensive and difficult. And without constant communication, putting people on the moon is an excessive risk. Of course, now I’m talking about…
