The new research from Calcutta suggests that remnants of that ancient planet known as Theia are still inside the Earth and explain the origin of the "lumps" near the core-mantle boundary. Other remnants of it coalesced to form the moon
Jupiter (Webb NIRCam image): This image of Jupiter from NASA's James Webb Space Telescope NIRCam (Near Infrared Camera) shows spectacular detail of the planet, which is impressive in infrared light. In this image, brightness indicates a high altitude . The many white "dots" and "marks" are likely very high-altitude cloud edges of condensed convection. The auroras, shown in red in this image, extend to higher altitudes over both the planet's north and south poles. In contrast, dark bands north The equatorial region has no cloud caps.

What is NASA planning for the ambitious Mars sample return mission?

  • No comments
In addition to bringing the first sample collected from Mars to Earth, this very complex mission will include the first launch from the soil of another planet, and also the first rendezvous in orbit around another planet. The return of the samples from Mars is a partnership with ESA (European Space Agency)

This figure illustrates how an interstellar object is rapidly approaching our solar system. Ejected from its home planet system long ago, the object traveled through interstellar space for billions of years before passing briefly in our cosmic neighborhood. The Robin Observatory will reveal many of these unknown interstellar visitors.

When the DART spacecraft crashed into the dimorphous asteroid, the body of the spacecraft hit between two large rocks and the two solar panels hit the rocks themselves. The yellow surface is a digital ground model of the impact site prepared from DART images, and the image of the DART spacecraft shows its position a few tens of milliseconds before impact. The white line coming out of the back of the spacecraft shows the trajectory of the spacecraft. The length of the spacecraft's body was about 1.30 meters from front to back.
