2022-05-26 17:31:47 Experiment to grow plants in soil from the Moon proved poor results

Scientists at the University of Florida planted cress seeds in 4 grams of lunar soil from each of the three Apollo missions and tracked their growth for 20 days.

Within 60 hours of planting, the research team found that the seeds had sprouted in all soil samples. Between day 6 and 8, the team removed a few seedlings so that only one plant grew for every gram of soil.

On the removed plants, they found that the roots grown in the lunar soil were stunted compared to plants grown in Earth's volcanic soil.

2022-05-26 17:31:47 New Horizons approached Pluto

New Horizons approached Pluto at a distance of 12,500 kilometers. For comparison, satellites in geostationary orbit "hang" over the Earth at a distance of 36,000 kilometers, which is almost 3 times farther

The apparatus has spent 9.5 years in transit and flew about 5 billion kilometers. At such a scale of travel, the accuracy of the "hit" is amazing.

2022-05-16 20:14:24 If you look closely at everything around you, you will see the clarity and thoughtfulness of shapes and lines in everything. The very structure of the world proves that it did not come out of nowhere. Or out of chaos, or out of an explosion... There is a Higher Intelligence behind it all!

The space around us is not something irrational, it communicates with us through sound, light, forms and signs. All this belongs to Sacred Geometry, the science of the principles of creation of the universe, expressed in geometric forms.

In sacred geometry every line and figure has its own spiritual meaning, which, when understood, makes it possible not only to know oneself, but also to comprehend the mystery of the universe. It expresses sacred knowledge, and principles in geometric form. Learning to use them, a person can create his own world, change not only the inner but also the outer space.

2022-05-15 07:40:05 Newly discovered glow of Martian atmosphere defies simple explanation

Scientists from the Mars mission, launched by the UAE, have observed a wavy, snake-shaped atmospheric glow that stretches over half of the Red Planet's surface.

This discovery of a "wavy, discrete" atmospheric glow, which was observed high in the atmosphere and is the result of the interaction of solar radiation with magnetic fields.

The intensity of the magnetic field of Mars is heterogeneous, and, in some places, it lacks field at all, so it is difficult to track the glow of the atmosphere on this planet

2022-05-15 07:40:05 What is the minimal size of black holes?

The mass of a black hole formed by the collapse of a larger star is limited by the Oppenheimer-Volkoff limit. Its exact value is not known, as it depends on many poorly understood parameters. In general, this limit lies between 2.14 and 2.17 solar masses.

All stars lighter than 2.14 solar masses are definitely not black holes. The highly probable BH candidates known today have significantly higher masses, from 6 solar masses and higher.

For primary (small) black holes the lower value is the Planck mass: 2.176⋅10^(-8) kg. But primary black holes are hypothetical objects and have not been discovered yet

2022-05-08 06:50:46 Europeans explore caves on the Moon

For a long time, NASA representatives have been curious about the underground world on the Moon. The European Space Agency also began to study it. Specialists argue that the existing caves on our planet's satellite may be quite suitable for the construction of space bases.

It is no secret that the Moon has no atmosphere. Radiation on the surface is extremely high. In addition, meteorites that fall on the moon have nowhere to burn. Therefore, during the construction of various structures for the life of the colonizers must be protected.

According to researchers, the best option is the lunar caves. Also water and minerals can be found there, both of which are useful for life support of lunar bases

2022-05-08 06:50:46 NASA plans to send a flagship mission to Uranus by 2049

A committee of NASA scientists has recommended that a flagship mission to Uranus be NASA's highest-priority major planetary science mission for the next decade.

Uranus is a virtually unexplored world; NASA's only visit to the seventh planet was a short flyby on January 24, 1986, during which scientists discovered the planet's rings and several additional moons.

At this point, an orbiter and probe to Uranus is not a specific mission, but a concept
