NASA and SpaceX launch a super-X-ray telescope to observe the universe

The US Aerospace Agency NASA launched an X-ray Imaging Polarimetry Research Mission (IXPE, abbreviation in English) last Thursday (9). The mission is the result of a joint effort by the Italian space agency ASI and 12 other international organizations.

The IXPE’s goal is to observe the polarization of X-rays in supernovae, supermassive black holes and high-energy objects scattered throughout the universe.

The launch was carried out from the Kennedy Space Center in Florida, USA. “Together with our partners in Italy and around the world, we have added a new observatory to our fleet that will shape our understanding of the universe for years to come. Each NASA aircraft is carefully selected for observations that open up new possibilities for science, and IXPE will show us a cruel universe around us like we’ve never seen before, ”said Thomas Zurbuchen, NASA Science Mission Catalog Administrator.

The SpaceX Falcon 9 rocket was responsible for putting the IXPE into orbit. The module contains three special telescopes with polarimetric detectors – a property that allows you to identify details in the light spectrum that can reveal the origin of electromagnetic radiation. IXPE is considered the successor to other polarized X-ray capture projects such as the Chandra Observatory, NASA’s premier X-ray telescope.

Microsoft improves Windows 11 update process

Published

on

Windows 11 users can always and automatically receive updates from Windows Update, but it looks like Microsoft is testing how to improve this system in the future.

With the release of the new version of Windows 11 22H2, Microsoft has confirmed that it also improves the Windows Update system, making it more stable and reliable, as well as preventing possible errors that may occur in the process.

According to the company, one of the first changes concerns the size of the updates themselves, which should now be significantly smaller. This allows users to download updates faster, but also reduces data consumption. What’s more, by focusing only on core components, users resent updates that are less likely to fail.

Another novelty is aimed at reducing Microsoft’s carbon footprint: the operating system now determines the best time to install updates in order to be as efficient as possible. In this case, Windows starts installing updates at a time when it is more appropriate for the use of “clean energy”.

All of these news should be found on Windows 11 22H2. This update from Microsoft is available to all users who are considered “crawlers” – those who manually search for updates through “Settings”.

If you don’t get it, try searching Windows Update a few times.

NASA will destroy the spacecraft against the asteroid - to see if it can protect the planet

The US space agency’s experiment, scheduled for the early hours of Monday, is aimed at assessing whether an asteroid that is on a collision course with Earth can be deflected.

NASA spacecraft will collide with the asteroid at dawn on Monday.

DART, short for “Dual Asteroid Redirection Test”, will encounter a space rock after launching 10 months ago. ship crash into the moon an asteroid to see how it affects the movement of this cosmic body.

The mission is heading towards Dimorphos, a small moon orbiting the asteroid Didymos. The asteroid system poses no threat to Earth, NASA says, making it an ideal target for a kinetic impact test, which could be necessary if one day an asteroid is on a collision course with Earth.

The event will be the first large-scale demonstration of sabotage technologies capable of protecting the planet. Collision is expected at 00:14 Monday.

At this time, Dimorphos will be relatively close to the Earth – within a radius of 11 million kilometers. In a collision with an asteroid, the spacecraft will accelerate to 24,140 kilometers per hour.

“For the first time, we will significantly change the orbit of a celestial body in the universe,” said Robert Brown, head of space science at the Applied Physics Laboratory at Johns Hopkins University.

A world dominated by ants

There are at least 20 quadrillion ants on Earth, according to a new study, which suggests that this staggering number likely underestimates the total population of these insects, which are an important part of the entire planet’s ecosystem. Determining the world population of ants is important for measuring the effects of changes in their habitat, including those caused by climate change. They play an important role in dispersing seeds, harboring organisms, and acting as predators or prey.

Some studies have attempted to estimate the world’s ant population, but the number has turned out to be much lower. In this new effort, published in the journal Proceedings of the National Academy of Sciences (PNAS), the researchers analyzed 465 studies that measured ant numbers locally on the ground. They used two standardized methods: setting traps that caught ants that passed over a certain period of time, or analyzing the number of ants on a portion of leaves delimited in the soil.

Although consultations were held on all continents, data were scarce or non-existent for some key regions, including Central Africa and Asia. Thus, “the actual number of ants worldwide is likely significantly higher” than estimated, the study says. “It is imperative that we fill in these remaining gaps to get a complete picture of insect diversity.”

According to the estimated number of ants, their total biomass on Earth is 12 million tons, which is more than that of birds and wild mammals combined, and 20% of human biomass. (From the newsroom, with AFP)
