Desert rock hints at a moon-sized world shattered in the Sun’s early days

A fist-sized Sahara meteorite called NWA 12774 is an angrite whose chemistry, analyzed with a new pressure-based barometer, implies it formed inside a large parent body—potentially Moon-sized—under high pressure and was destroyed during the solar system’s infancy. Its silica-poor composition points to a formation pathway different from Earth or Mars. If correct, this would be evidence for a vanished protoplanet whose debris helped seed the early planets; further independent checks on similar meteorites are needed to confirm the giant-parent picture.

First Image Captures a Baby Planet Forming in a Star's Ring

Scientists have captured images of a tiny baby planet, WISPIT 2b, forming inside its star's ring, making it the first of its kind to be directly observed in this way. Located 437 light-years away, this gas giant is just five million years old and was spotted within a gap in the protoplanetary disk of its star, WISPIT, using advanced telescopes. The discovery also hints at a possible second planet forming in the same system.

Astronomers Observe Birth of a New Planet and Its Impact on Surrounding Dust

Astronomers have observed a newborn planet forming within a dust disc around a star 440 light years away, providing insights into Earth's early formation, and also discovered a dim companion star orbiting Betelgeuse, which may explain its brightness fluctuations and its impending supernova.

"Alien Origins: Earth's Mantle Holds Traces of a Long-Lost World"

Scientists propose that the Earth's mantle contains two extra-dense blobs, known as large low-velocity provinces (LLVPs), which may have been leftover from a collision between Earth and a protoplanet called Theia 4.5 billion years ago. Seismic wave measurements suggest that these blobs are compositionally different from the surrounding material. Simulations indicate that during the collision, molten material from Theia mixed with the Earth's upper liquid layer, while denser solid material sank and embedded itself in the solid layer below. Further research will involve comparing rock samples from the Earth's mantle with samples from the Moon to support the idea of a rock exchange program between the two proto-worlds.

Ancient Alien World Remnants Found Near Earth's Core

A new study suggests that remnants of the Mars-size rock, Theia, which collided with Earth and helped create the moon, may be buried near Earth's core. Computer simulations indicate that dense relics of Theia's mantle could have sunk and solidified in Earth's lower mantle, forming continent-size blobs that are more iron-rich than Earth's normal mantle rock. These blobs could have influenced geological activity unique to Earth, such as plate tectonics and subduction. Traces of these relics could potentially make their way to the surface through mantle plumes. The findings provide insight into Earth's geological evolution and its distinct characteristics compared to other rocky planets.

"Discovery: Protoplanet Found 374 Light Years Away, Shaping a New World"

Astronomers have confirmed the existence of a protoplanet, HD169142 b, located 374 light years away from Earth. Using data from the SPHERE instrument of the European Southern Observatory, researchers from the University of Liège and Monash University were able to detect the thermal signature of the forming planet. The protoplanet, which is still in the process of gathering material, is located in a disk of gas and dust surrounding the star HD 169142. This discovery increases the number of confirmed protoplanets to three and provides valuable insights into the early stages of planet formation. Further observations with the James Webb Space Telescope could provide additional characterization and confirmation of the protoplanet.

Third Protoplanet HD 169142 b Confirmed by Researchers

Researchers from the University of Liège and Monash University have confirmed the existence of a third protoplanet, HD 169142 b, using data from the SPHERE instrument of the European Southern Observatory. The protoplanet is located in the disk of gas and dust surrounding HD 169142, a star 374 light years from our solar system. The discovery was made possible by advanced image processing tools developed by the PSILab of the University of Liège. The protoplanet is still gathering material and is buried in a significant amount of dust, which could be in the form of a circumplanetary disk. Further characterization of the protoplanet could be obtained through future observations with the James Webb Space Telescope.

New Planet Confirmed by Researchers

Monash University astronomers have confirmed the formation of a protoplanet in the HD 169142 system using near-infrared images captured by the European Southern Observatory's Very Large Telescope. The protoplanet is located approximately 37 au from the star and has carved a gap in the disk surrounding it. The planet is buried in a significant amount of dust, which reflects stellar light, and is expected to have a circumplanetary disk that could form small satellites such as moons. The discovery of HD 169142 b is the third exoplanet to be imaged during formation, and it is an exciting target for the recently deployed James Webb Space Telescope.
