Asteroid Dimorph “lost weight” by a thousand tons as a result of the DART impact
The Dimorph ram took place on September 26, 2022. A few minutes after the impact, the Italian cubesat LICIACube made a close flyby of the asteroid. The pictures he took showed that the impact knocked out a large amount of matter from the surface of the Dimorph. According to experts, during the subsequent analysis of…

Incredible image of the Sun’s activity
In 2014, photographer and amateur astronomer Matt Malloy created an incredible image of the Sun’s activity by combining a huge number of photos transmitted to Earth by NASA’s SDO Solar Dynamics Space Observatory. To create the image, Molloy used images taken between September 1 and October 8 of the same year. The author of the…

Juno will explore a volcanic satellite
The Juno probe, operating in the Jupiter system since 2016, continues to study its satellites. On December 15, scientists sent a team to it, which will transfer it to a new orbit. On it, the device will be able to teach Io during close flights. Juno has previously studied the other two of Jupiter’s four…

Astronomers have discovered anomalies in the cores of red giants
Red giants are dying stars in advanced stages of stellar evolution that have depleted the hydrogen reserves in their cores. Astronomers have discovered new evidence that red giants experience “disruptions”—abrupt structural changes—in their inner core. Unfortunately, it is impossible to look directly inside the star. However, a method called asteroseismology, which measures fluctuations similar to…

Astronomers have found a potentially habitable exoplanet near a red dwarf
Super-Earth LP 890-9 c is located within the habitable zone of its star, a calm and “soft” red dwarf. According to the authors of the find, this is the second in the list of the most promising candidates for the presence of life outside the Solar system. Two exoplanets from the class of super-earths have…

The meteorite NWA 7034 has a second, more poetic name: “Black Beauty”
It was found in the Moroccan part of the Sahara Desert in 2011. Scientists immediately determined that it was a fragment of Martian rock. At the moment, the “Beauty” is recognized as the oldest sample from the surface of Mars! The basalt that forms its basis froze 4.44-4.48 billion years ago, or just a hundred…

Asteroid 2015 RN35 will approach Earth on December 15
“Asteroid 2015 RN35 is large enough and will fly very close so that amateur astronomers can observe it,” scientists say. It was called the “Christmas asteroid” and specified that it reaches 140 m in diameter. Residents of the Southern hemisphere of the Earth will be able to observe it. It is reported that the asteroid…

The Perseverance rover recorded the sound of a Martian dust vortex passing over it
With the help of a microphone mounted on the SuperCam instrument, the Perseverance rover working in the Lake crater managed to record the sound that accompanied the passage of a dust vortex over it. It was possible to calculate that the vortex was 25 meters across and 118 meters high. He was moving at a…

The solar system is surrounded by mysterious light pollution
Scientists conducted a study based on observations of the Hubble telescope. The results indicate the presence of a mysterious glow surrounding the Solar System, which may lead to a revision of the model of its structure. 200 thousand Hubble images were sorted. The light of planets, stars, galaxies, asteroids and other known objects of observation…

Parker Solar Probe undergoes another approach to the Sun
NASA’s Parker Solar Probe continues to travel around the Sun and explore its atmosphere. Today is the 14th rendezvous of the spacecraft with our star. At the closest point to the surface of the Sun, Parker Solar Probe was located at a distance of 8.5 million kilometers. At that time, he was moving at a…
