Granite Discovery Indicates Moon is More Similar to Earth Than We Believed

Credit: unplahBy utilizing microwave instruments to examine the depths of the Moon's far side, scientists have identified a significant subsurface granite formation referred to as a "hotspot." This discovery implies that the Moon possesses greater similarities to Earth than what was previously assumed.Granite formations are typically found on Earth as a result of the...

For the First Time Ever, Scientists Drill Into the Earth’s Rocky Mantle

Credit: Istock.As per a recent report from the Washington Post, scientists have successfully reached Earth's mantle by drilling approximately one mile beneath the ocean floor. This significant accomplishment was made possible by the JOIDES Resolution, an ocean drilling vessel.It is important to clarify that the scientists did not precisely drill into the mantle, and...

Earth’s Internal Core Rotation May Have Paused and Perhaps Reversed

Earth's inner core.

The authors show proof that oscillation in the rotation of the internal core coincides with periodic changes in the Earth's surface...

Rare, Green Comet Passes Earth For the First Time in 50,000 Years

Credit: Awareness Act.Last year, astronomers discovered Comet C/2022 E3 ZTF, which had not been visible until then due to its distance from Earth. However, it is now approaching Earth, and soon it will be making its closest approach in 50,000 years. Astronomers have stated that this will be the only chance to see it...
