The explosion gave rise to a powerful cosmic “firework”, the energy of which would be enough for the Sun to shine for 10 million years. At the same time, the gas of the former nebula moves at a speed of 150 kilometers per second away from the epicenter of the explosion, which is approximately equal to the speed at which the Sun rotates around the center of the Galaxy.
The stars survived this collision and are now flying away at a speed of about 13 and 29 kilometers per second.
The Falcon 9 rocket successfully launched from launch pad 40 at Cape Canaveral in Florida. She sent an ispace landing platform to the moon with scientific equipment, including a rover from the UAE.
As a passing load, the NASA Lunar Flashlight cubesat was sent, which will search for water ice near the South Pole from the orbit of the Moon. Both vehicles are launched in a low-energy orbit. Hakuto-R will arrive to the moon in four months, and Lunar Flashlight in three.
After the launch, the first stage of the Falcon 9 landed safely on the landing pad.
The Hubble Space Telescope has discovered that a peculiar little galaxy is one of the most incredible examples of galaxies with extremely low metal content. This suggests that the chemical composition of the galaxy has hardly changed in more than 13 billion years.
Shortly after the Big Bang, only hydrogen and helium were present in the universe. All other elements, called metals in astrophysics, were formed after the very first stars burst into supernovae. These supernovae “polluted” the parent galaxies and led to the formation of new stars and planetary systems.
But the Peekaboo galaxy hasn’t experienced much of this, and for that reason has remained metal-poor all this time.
Since 2015, the LIGO-Virgo-KAMA collaboration has detected about 85 pairs of black holes colliding with each other.
It is known that these cosmic catastrophes occur frequently: as the sensitivity of the detector increases, scientists expect that in the next cycle of observations, starting in 2023, they will receive data on these events almost daily. However, scientists do not yet know what causes these collisions.
The team conducted two more soil samples on Mars in the Jezero crater.
Studies of the Martian regolith will be valuable not only from the point of view of studying the geology of the planet, but also for a better understanding of the impact of this fine dust on instruments and the human body.
Kubsat carries two types of yeast on board. As part of the experiment, the impact of cosmic radiation on the development of living organisms in deep space conditions will be studied.
The data on the damage of yeast genetic material will be used in the scientific works of the Ames Research Center dedicated to the protection of astronauts’ organisms outside of low Earth orbit.
Here is a color image of the craters Munch (bottom) and Sander (top), located in the area of the Plain of Heat on the surface of Mercury.
The bottom of the 50-kilometer Sander crater is covered with light material, and the 58-kilometer Munch crater has a dark “rim”.
It may seem that the white material is water ice, the existence of which has been proven in the polar craters of Mercury. However, in this case, this is excluded, since the Sander crater is not in eternal shadow, and in the daytime it heats up to +427 degrees Celsius.
NASA explained this feature as follows: “In most areas of Mercury, daytime temperatures are so high that some stones and minerals—which remain unchanged elsewhere in the Solar System—begin to evaporate on the planet closest to the Sun.”
Australia on Monday began construction of an extensive antenna network in a sparsely populated area, part of which, according to designers, will eventually become one of the most powerful radio telescopes in the world.
When everything is ready, the antennas in Australia and the dish network in South Africa will form a massive instrument whose purpose is to unravel the mysteries of the formation of stars, galaxies and extraterrestrial life.
The idea of the telescope first arose in the early 1990s, but the project suffered from delays, funding problems and diplomatic machinations.
According to the Director General, the telescope “will become one of the greatest scientific achievements of mankind.”
Scientists together with astronomers of the Keck Observatory are investigating the formation and behavior of clouds of Saturn’s largest satellite.
The image on the left uses a filter that allows you to look beyond the lower layers of the atmosphere. Bright spots are clouds in the northern hemisphere.
On the right is a color composite image. Kraken Mare is a sea of methane, Belet is dark sand dunes, Adiri is an area with high reflectivity.
The two clouds seen by Webb confirm the theory that clouds form in the northern hemisphere at the end of summer when the Sun warms its surface. Subsequent observations by the Keck Observatory also revealed clouds confirming seasonal weather conditions.
Titan is a unique object of the Solar System. This is the only body other than the Earth on which there are rivers, lakes and seas. They do not consist of water, but of hydrocarbons such as ethane and methane. It is also the only satellite with a dense atmosphere.
Scientists have recorded minerals in the El Ali meteorite that have never been found on Earth before.
The meteorite was found in Somalia two years ago, it weighs about 14 tons. After its discovery, the 70-gram part was sent to the university for research. As a result, two new minerals were found there — elaliite and elkinstantonite. Experts also reported that they may have found another rock in the samples, which experts have never seen in the natural environment on Earth.
The authors hope that they will be able to discover other unknown minerals if they can take more samples from the meteorite, but the fate of the space object remains unclear — according to the information available to scientists, the meteorite was transported to China in search of a potential buyer.
