New Technology Aims to Clean Up Space Junk

NASA has awarded a contract to TransAstra to clean up space junk. One category of debris they will target is CubeSats, small satellites the size of a Rubik’s Cube. The recycling centers would allow the collected debris to be recycled.

This Meteorite Left Earth. Thousands of Years Later, It Came Back

 Scientists are seeking to confirm that a black rock discovered in Morocco in 2018 departed Earth's pull for outer space, only to return to it like a prodigal child.

Scientists discover the origin of water in our solar system

New findings suggest the water originates from the space between solar systems, billions of years before the birth of our sun.

Scientists have discovered a new core at the center of the Earth

The new layer of the inner core consists of an iron-nickel alloy, like other parts of the core, but it has a different crystal structure.

Earth's inner core may have stopped turning and could go into reverse

Chinese scientists say that based on their calculations, a small imbalance in the electromagnetic and gravitational forces could slow and even reverse the inner core’s rotation. 

Total solar eclipse plunges Antarctica into darkness

Totality was visible only in Antarctica on early Saturday, experienced by a small number of scientists experts and adventure tourists.

Remnants Of Recent Supernovae Found in the Earth's Crust

Recently Australian researchers found the first ever evidence of a plutonium radioactive isotope in the Earth's crust that originally came from outer space, namely a supernova.

US-European Mission Launches to Monitor the World's Oceans

Sentinel-6 satellite lifted off on a SpaceX Falcon 9 rocket on Nov 21. Its mission now is to measure and chart the rise of the sea level more precisely than ever before. 

Earth may have been wet since it formed

A new study finds that Earth's water may have come from materials that were present in the inner solar system at the time the planet formed - instead of far-reaching comets or asteroids delivering such water.

Exploding stars may have caused mass extinction on Earth

Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth.

The Mysterious Anomaly Is Weakening Earth's Magnetic Field

The South Atlantic Anomaly is a vast expanse of reduced magnetic intensity in Earth's magnetic field, extending all the way from South America to southwest Africa.

Two commercial satellites link up for first time

A robotic servicing spacecraft has hooked up with an aging satellite over the Pacific Ocean. It accomplished the first link-up between two commercial satellites in space, and the first docking with a satellite that was never designed to receive a visitor.

Australian meteor crater is the oldest known crater on Earth

A NASA scientist analyzed the age of the Yarrabubba meteor crater in Australia and found it to be 2.229 billion years old, making it now the oldest crater currently known.

A Place on Earth with Liquid Water But No Life

 We get excited when we detect water on another world, which so far hasn’t happened often. But this study shows that the presence of water, though tantalizing and worth pursuing scientifically, guarantees nothing.

NASA launches a space weather satellite to ionosphere

The satellite called Icon, or Ionospheric Connection Explorer, will transmit data intended to help scientists understand the physical processes at work where Earth's atmosphere interacts with near-Earth space.
