Each year in August, stargazers in the Northern Hemisphere get the chance to observe one of the most fascinating meteor showers – the Perseids. Perhaps you already got your chance to see some shooting stars since the beginning of the astronomical event in July but if not… tonight will be the best chance to spot some falling meteorites.
American scientists using NASA’s Chandra and Swift space observatories have captured a bright short-lived phenomenon – a sequence of concentric rings around a black hole, which are echoes from X-ray flares. Such images of giant X-ray rings provide new information about the dust contained in our Galaxy.
Scientists from the University of Hong Kong (HKU) have presented new research that challenges the popular Gale crater hypothesis on Mars. Until now, data from the Curiosity rover indicated that this crater in ancient times could have been a deep lake. However, an alternative view of the same data showed that the crater may have never been a Martian lake.
With the help of the ALMA telescope, scientists have carried out accurate temperature measurements on the surface of the asteroid Psyche. The object is known to be worth more than the entire global economy of our planet and will be the target of an upcoming NASA mission in 2022.
By the standards of the stars, the Sun is now “a moderately plump star in its prime.” But to thoroughly understand its evolution and try to predict future development, scientists need to find out what such bodies were like at earlier stages of development. Observations of young stars of the same type and, of course, modeling help a lot in this process.
The Perseverance rover successfully drilled its first hole in the Martian surface, but subsequent analysis showed that the sampling tube did not grab any of the intended Martian soil.
Astronomers using ground-based and space telescopes were able to determine that winds are responsible for the anomalous heating of the upper atmosphere of Jupiter, which transfers heat from regions where auroras are raging to the equator of the giant.
The moon was formed about 4.5 billion years ago, from material ejected into orbit after the collision of the Earth with a massive celestial body. At first, the satellite was molten and had its own magnetic shield, traces of which can be found today in local minerals.
Astronomers presented the results of studies of the multiplanetary system L 98-59, which is located 35 light-years from the Sun. They managed to find two new exoplanets in it, and also determine that the system includes a planet with large reserves of water and a planet located in the habitable zone.
