Theories of the formation of the Milky Way can be revised as a result of a discovery based on the study of the behavior of the oldest stars of our Galaxy. A study of the orbits of the most metal-poor…
The Vega booster failed a few minutes after the launch of 17 November from French Guiana, resulting in the loss of two satellites as a result of the second missile failure in its last three launches. The Vega rocket launched…
A group of astronomers led by Anna Schauer from the University of Texas at Austin, USA, found that the lunar telescope, the idea of which was considered by NASA about 10 years ago, can solve a problem that none of…
Minerals from Mars zircon containing uranium is one of the main components of the continental crust of the Earth, providing information on the age and origin of continents, as well as on large geological features, such as mountain chains and…
“Landing on Mars is extremely difficult, and there is no right to make a mistake,” says Francois Spoto, head of the ExoMars program team. “The last test was a good step forward, but this is not the ideal result that…
Using the Very Large Telescope of the European Southern Observatory, astronomers studied ionized gas in the central regions of the Seyfert galaxy NGC 7130. In their work, the researchers identified a complex, multicomponent release from this galaxy. Active galaxy nuclei…
One of the key questions of cosmology is the determination of the exact speed of expansion of the universe. Two modern methods for determining this rate give different, contradictory values. In a new study, physicist David Harvey of Leiden University,…
The Y chromosome may be in trouble. The sex we’re assigned at birth depends largely on a genetic flip of the coin: X or Y? Two X chromosomes and you (almost always) develop ovaries. An X and a Y chromosome?…
In one galactic year, also known as a cosmic year, the sun orbits the Milky Way. Humans are used to keeping time by measuring Earth’s movement relative to the sun. But while Earth’s trips around its star are noteworthy to…
The information locked inside black holes could be detected by feeling their ‘hair,’ new research suggests. Black holes are celestial objects with such massive gravity that not even light can escape their clutches once it crosses the event horizon, or…
An illustration of the Big Bang and the expansion of the universe. Has the universe been around forever? If so, perhaps it’s been bouncing back and forth in a never-ending cycle of big bangs in which all matter bubbles out…
An image of the Kepler supernova remnant, captured with NASA’s Chandra X-Ray Observatory. A different type of stellar explosion, called a black dwarf supernova, may light up the darkness at the end of the universe. At the end of the…
