Ancient Moon’s Origins Revealed: Theia’s Planetary Remains Found Deep Below

A groundbreaking study has offered fresh insight into the mysterious origin of Earth’s moon. Scientists have long theorized that an ancient planet named “Theia” collided with Earth approximately 4.5 billion years ago, resulting in the formation of our natural satellite. However, evidence for what happened to Theia after the collision remained elusive until now.

New data from NASA’s Gravity Recovery and Interior Laboratory (GRAIL) spacecraft has revealed the presence of large deposits of titanium-iron ore deep beneath the moon’s surface. This discovery suggests that Theia’s remains are indeed responsible for the creation of Earth’s moon.

The study focused on gravity anomalies detected by GRAIL in areas beneath the moon’s crust known as its mantle, located between the crust and core. These regions displayed dense matter consistent with titanium and iron “ilmenite” deposits, supporting earlier predictions made by comp

Samsung has unveiled a new line-up of its flagship smartphones, introducing a number of artificial intelligence features that the phone maker says will usher in a ‘new era of mobile (phones).’ will begin.

The Galaxy S24, S24 Plus and S24 Ultra mobile phones will go on sale from January 31.

The Korean technology giant says that these mobile phones will be equipped with Galaxy AI capabilities.

These mobile phones include several artificial intelligence tools. The phone has real-time translation capabilities for voice calls and texts, a chat assist tool to suggest the correct tone for messages, a note-taking and voice-to-text tool that will convert phone conversations into text. This tool will be able to translate conversations and even generate summaries of conversations with bullet points.

In addition, the S24 range will be among the first devices to use Google’s Circle to Search feature, which will allow users to circle, highlight or tap on anything on the screen.

For example, when a specific item or a franchise is highlighted in a video, it will trigger a search on the website about it.

The feature can be used in any app running on the phone and so far only the S24 range and Google’s flagship Pixel 8 mobile phones have been confirmed to feature the feature.

AI tools have been extended to the camera. New editing tools are available to rearrange images. Also, the space created when an object in the images is removed from its place

It is not unusual for China to achieve milestones in space exploration that the United States does not yet have to its credit, such as successfully landing on the far side of the Moon or bringing samples from the youngest regions of the satellite to Earth. But what happens if China hits where it hurts?

The two most important exploration missions for NASA right now are to bring to Earth the rock samples that the Perseverance rover is collecting on Mars and return to the Moon after 50 years with the first woman. As the space agency’s budget problems and its partners’ delays put these two missions in jeopardy, China is more likely to achieve both before NASA.

Mars Sample Return

Overshadowed by the fame of its small companion Ingenuity, NASA’s Perseverance rover has done a brilliant job selecting samples of Martian rocks and depositing them in tubes on the surface of Mars so that NASA and the European Space Agency (ESA) can bring them back to Earth in the future Mars Sample Return (MSR) mission.

The news is that NASA has just halted MSR development in an attempt to contain its budget after a pair of expert committees concluded that the mission cannot be completed until 2040 with a budget of between $8 billion and $11 billion. , more than double what was expected.

What is MSR? The first mission to bring samples from another planet is, as expected, quite complex, and its design has been changing. It essentially consists of launching a European spacecraft, Earth Returner Orbiter (ERO), and an American spacecraft, Sample Retrieval Lander (SRL), to Mars to recover the tubes from the Perseverance rover on the surface of Mars and bring them back to Earth for analysis. .

Until a few days ago, the plan was for ERO to launch in 2030 and remain orbiting the red planet waiting for the SLR. The SLR would launch in 2035 and descend to the surface of Mars to collect up to 30 sample tubes from the Perseverance rover. The samples would be delivered by Perseverance itself, if it were still operating by then, or they would be picked up by two

Self-driving cars cannot correctly detect if the car in front is dark in color. This is because the “Light Detection and Ranging (LiDAR)” sensor, called the eyes of self-driving cars, cannot correctly detect black objects that absorb light. A national research group has developed a new material that will solve the black “color blindness” of self-driving cars.

Changmin Yoon, professor at the Department of Chemical and Biological Engineering of National Hanbat University, published the results of his research on developing a black plate-shaped material that can be recognized by LiDAR in the international academic journal ‘American Chemical Society (ACS) Applied Materials and Interfaces last month. The article received enough attention to be featured by ACS as an interesting research finding.

LIDAR fires a near-infrared laser at an object and measures the time it takes for the reflected wave to arrive to determine the distance. However, black objects absorb the light emitted by the LIDAR and the recognition speed decreases dramatically. This problem is also one of the reasons why Tesla, which is synonymous with self-driving cars, does not choose LiDAR. If the car in front is dark in color, there is a possibility of a collision.

Leitz Phone 3 Introduces Revolutionary Leitz Filter Camera Mode

Leica is known for its legendary lenses, and now, Leitz Phone 3 is bringing that same quality to mobile photography. The Leitz filter camera mode on the Leitz Phone 3 can simulate the most famous Leica lenses, including the Noctilux-M 1:1.2/50 mm, Summilux-M 1:1.4/28 mm, and Summilux-M 1:1.4/35 mm.

But the benefits don’t stop there. The Leitz Filter camera mod

After years of successive postponements, Boeing’s Starliner spacecraft was to take off for the first time on Monday, May 6 in the evening with astronauts on board, heading for the International Space Station, and thus joining the very private club of spaceships that have transported humans. Unfortunately, its takeoff was canceled about two hours before the scheduled launch time, due to a technical problem. An anomaly was identified on a valve of the Atlas V rocket which was to propel the capsule into orbit, announced the launcher manufacturer, the ULA group. Fallback dates are possible this week for a new takeoff attempt but no new date has been announced immediately.

However, the company was playing big on this final test mission, which should allow it to demonstrate that its ship is safe before starting regular missions to the Space Station (ISS) four years behind SpaceX. Only a handful of American ships have carried astronauts in the past. SpaceX’s Dragon capsule joined this list in 2020, succeeding the legendary Mercury, Gemini, Apollo and space shuttle programs. After the latter stopped in 2011, NASA astronauts had to travel aboard Russian Soyuz spacecraft. It is to put an end to this dependence that in 2014, the American space agency sig
