Last week, our planet was hit by a solar storm and an asteroid about 3 meters in size, but none of the events posed a danger to people. Meanwhile, new discoveries about the universe were announced.

Scientists are learning more about solar storms as the Sun enters its current cycle of peak activity in the coming years. On March 14 and 15, some of them, classified as mild and moderate, arrived on our planet.

Such solar storms can cause only minor effects on Earth, such as an increase in the frequency of auroras at certain latitudes of the planet and short-term problems with high-frequency radio signals. Solar maximum is expected around July 2025.
It appears that the impact of comets and asteroids hitting Mercury at very high speeds turned the carbon that covers much of the planet’s surface into diamonds. The solar system’s innermost planet could have a layer of graphite more than 90 meters thick, according to a new study.
Under the pressure of asteroid impacts, about 60% of graphite can be turned into “impact diamonds”. This will mean about 16 quadrillion tons of diamonds. But this is unlikely to lead miners to the ultimate space adventure: Mercury’s diamonds are likely to be impure, as well as a messy mixture of graphite and other carbon phases.
While there are no potentially dangerous asteroids in their path to impact Earth, no one can guarantee you that there are no other undiscovered space rocks ready to crash into our planet before a telescope detects them. More or less it happened on Friday (11).
A small asteroid was discovered last Friday (11) by astronomer Christian Czernecki, and just two hours later the object passed through the Earth’s atmosphere. Luckily, it was about 3 meters in diameter and would have been destroyed as it passed through the atmosphere. Some Icelanders reported seeing a glow in the sky during the event.
The James Webb Telescope has completed the refinement phase of its instruments, which means that all optical parameters have been checked and tested and they work as expected (perhaps even beyond the norm). At the end of the process James Webb Starr 2MASS J17554042+6551277. registered on And also the object in the background.
As we can see in the image above, the on-board optical system and camera sensitivity are able to capture background stars and galaxies. Before you can begin scientific work with the telescope, you must complete the setup. between them, James Webb, photographed by the Gaia Observatory,
Two stars in the SVS 13 system, 980 light-years away, have been seen with disks of gas and dust around them. These disks appear to be large enough to form new planets and have been identified with unprecedented accuracy. He discovered about 30 different molecules and 13 complex organic molecules that were the precursors of life.
This suggests that planet-forming disks may indeed exist around stars in binary systems. But it’s unclear exactly how new planets might form, mainly because the gravitational interaction between two stars is complex. In addition, a large disk is forming around both stars.
#mars helicopter can’t be stopped! Ingenuity has successfully completed its 21st mission to the Red Planet. The small rotorcraft flew 370 meters at a speed of 3.85 meters per second and remained in the air for 129.2 seconds. https://t.co/TNCdXWcKWE pic.twitter.com/rNMaodihxa

Hey Ingenuity Helicopter completed its 21st flight, covering 370 meters at a speed of 3.85 m/s. In total, it has already covered more than 4.6 km since its first flight over the Red Planet. In the last “landing” the plane was in the air for 129.2 seconds.
Due to the success of his adventures on Mars, the Ingenuity mission will be extended until September. The helicopter is expected to assist the Perseverance rover over the next few months as it continues to test its flight capabilities in the thin Martian atmosphere.
NASA astronaut Mark Vande Hey broke the record for the longest U.S. space flight (15) on Thursday. It reached the space station (ISS) last April and passed the 340-day mark on board. His mission was supposed to last six months, but the astronaut’s stay was extended, giving NASA an opportunity to evaluate the impact of microgravity on long-duration spaceflight.
The dark matter of the universe, which probably consists of some hitherto unknown particle, could multiply as a result of collisions with particles of “ordinary” matter at the beginning of the universe. This process could explain why there is so much more dark matter than what we see in the universe.
Shortly after the Big Bang, the universe will become compact enough for a series of interactions between particles to occur, according to a new study. Thus, a dark matter particle and a normal matter particle can collide and produce two dark matter particles. This would lead to the exponential reproduction of dark matter until the expansion of the Universe would push it away, thereby stopping the collision process.
The controversial and hypothetical Planet 9 has not been found in a rescan of the outermost region of the solar system. Astronomers have scanned about 87% of the sky with the Atacama Space Telescope (ACT) to find an object that could exist outside of Neptune’s orbit. This led them to rule out the existence of Planet 9 in the study area with a 95% chance.
If it really existed, the planet would have a mass of 5 to 10 Earth masses and would revolve around the Sun at a distance of 800 astronomical units. But the new results are disappointing, as the presence of this body could explain the strange orbits of other objects already found there.
