The first dark comet — a celestial object that looks like an asteroid but moves through space like a comet — was reported less than two years ago. Soon after, another six were found. In a new paper, researchers announce the discovery of seven more. go.nasa.gov/4ipb3PJ

“Dark comets are a new potential source for having delivered the materials to Earth that were necessary for the development of life,” said one of the scientists involved. “The more we can learn about them, the better we can understand their role in our planet’s origin.”

Using data from ESA - European Space Agency's Rosetta mission, a team of NASA-led scientists have reopened the case for comets like 67P as potential sources of water for early Earth. https://go.nasa.gov/4g1SQq0

Water was essential for life to form and flourish on Earth and it remains central for Earth life today. While some water likely existed in the gas and dust from which our planet materialized around 4.6 billion years ago, much of the water would have vaporized because Earth formed close to the Sun’s intense heat. How Earth ultimately became rich in liquid water has remained a source of debate for scientists.

Jupiter's moon Europa. About the same size as Earth's moon, but with a very intriguing difference: evidence suggests that beneath its icy crust, Europa hides a global ocean of liquid water – with more water than all of Earth's oceans combined!

Two weeks from today, the launch period opens for NASA's mission, which will send a robotic spacecraft bristling with high-tech science instruments to find out if this icy world has the conditions that could sustain extraterrestrial life.

A plume of Saharan dust lofted over the Atlantic Ocean on August 24.

The Sahara Desert is Earth’s largest source of airborne dust, which can travel for thousands of miles. Saharan Air Layer activity subsides after mid-August, according to NOAA, making it less likely that the plume shown here is bound for a transoceanic journey. Instead, it arcs to the north after blowing out over the ocean. Earlier in the summer, however, several clouds of fine dust from the Sahara reached the United States, creating hazy skies over Texas.

Scientists are interested in summertime Saharan dust events in part because of the influence they can have on large storm systems. Dry, stable, dust-laden air can inhibit tropical cyclone formation in the North Atlantic.
