This week included many space events, perhaps the most prominent of which is that scientists have found the largest known structure in the galaxy, and a number of astronauts joined the Artemis mission to the moon and then to Mars, who are young graduates after a two-year training in NASA, and other important matters about Mars Dark energy, as well as space observatories, which we give you details about, according to the US “space”, in this week’s events in space.
The NASA space graduates party
The last class of astronauts, known as “turtles”, graduated from basic training on Friday (January 10), as a ceremony for this twenty-second class of astronauts was held at the Johnson Space Center in Houston.
Study: dark energy does not exist
A new study took samples from several galaxies containing a certain type of supernova, and says that dark energy may not be real after all, and dark energy is a hypothetical form of energy that would explain the accelerating expansion of the universe, and others differ in The scientific community with conclusions.
The largest known structure in our galaxy
The flow of gas and small stars called “Radcliffe Wave” may be the largest single structure discovered in the Milky Way, according to new research published on Tuesday (January 7), and it includes about 800 million stars, and spans about 400 light years.
Arecibo observatory is exposed to an earthquake
On Tuesday (January 7), Puerto Rico was hit by a 6.4-magnitude earthquake, which is the strongest series of earthquakes to hit the island recently.
On the same day, a representative of Arecibo Observatory on the island announced that a survey of the massive radio broadcast had found that it had not suffered any damage, and is one of the major facilities in the United States to monitor nearby asteroids.
Water vapor on Mars regularly escapes from the planet
Water escapes to Mars faster than previously thought, as recent research indicates that water vapor can float regularly enough high in Mars’ atmosphere and escape from the planet without being restricted to condensation.
This information can help scientists understand how the Red Planet lost its ancient bodies from water.
