Planet Wandering the Galaxy

  Astronomers have identified more than 4,000 exoplanets orbiting other stars but just a few “rogue planets” wandering the galaxy without a star to call home. A new study claims to have spotted one of these worlds, and it may be a small, rocky world like Earth. If confirmed, the …

NASA 2068 Asteroid ?

  Earth has been bombarded by space rocks throughout its history, but we’re lucky no large ones have slammed into the planet lately. Astronomers keep a careful watch on the skies, hoping to spot potential impactors far enough in advance that we can do something about it, and one of …

Near Earth Asteroid Bennu

On October 20, 2020, NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) spacecraft briefly touched an asteroid to collect regolith (rocks and dust) from the surface of the near-Earth asteroid (101955) Bennu. All spacecraft telemetry data indicates the sample collection event, known as ‘Touch-And-Go’ (TAG), executed as expected. …

Ancient Magnetosphere

Solar storms strip a planet’s atmosphere over time, and only a strong magnetosphere would be able to provide maximum protection. Lunar samples gathered by NASA’s Apollo missions recently revealed that the Moon had its own global magnetosphere, lasting from about 4.25 to 2.5 billion years ago. According to new research, …

Earth Asteroid Bennu

NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) mission to the near-Earth asteroid Bennu is designed to return a carbon-rich sample of the asteroid to Earth. This 500-m-diameter body was chosen as the mission target due to its spectral similarity to primitive and organic-rich carbonaceous chondrite meteorites. In …

NASA Satellite Crashes

  During the height of the space race in the 1960s, the US launched a series of satellites designed to study the planet. The six Orbiting Geophysical Observatory (OGO) spacecraft improved our understanding of Earth’s magnetic field, shutting down a few years later. However, one of those forlorn satellites known …

Origin Of Water On Earth

  If you remember even basic elementary school geography, you know that Earth’s surface is mostly water. Scientists have disagreed about how all that water ended up on Earth. Was it all here when the planet formed, or was Earth a dry husk until asteroids and comets delivered water? A …

Chondrite Like Asteroids

A type of meteorite called an enstatite chondrite has similar isotopic composition to terrestrial rocks and thus may be representative of the material that formed Earth. A new study published in the journal Science shows that these meteorites contain sufficient hydrogen to have delivered to Earth at least three times …
