How energy-efficient is cloud computing?

(PhysOrg.com) -- Conventionally, data storage and data processing are done at the user's own computer, using that computer's storage system and processor. An alternative to this method is cloud computing, which is Internet-based ...

4 billion-year-old relic from early solar system heading our way

An enormous comet—approximately 80 miles across, more than twice the width of Rhode Island—is heading our way at 22,000 miles per hour from the edge of the solar system. Fortunately, it will never get closer than 1 billion ...

Interstellar comets like Borisov may not be all that rare

In 2019, astronomers spotted something incredible in our backyard: a rogue comet from another star system. Named Borisov, the icy snowball traveled 110,000 miles per hour and marked the first and only interstellar comet ever ...

Comet Catalina suggests comets delivered carbon to rocky planets

In early 2016, an icy visitor from the edge of our solar system hurtled past Earth. It briefly became visible to stargazers as Comet Catalina before it slingshotted past the Sun to disappear forevermore out of the solar system.

Meteors help Martian clouds form

How did the Red Planet get all of its clouds? CU Boulder researchers may have discovered the secret: just add meteors.

Early protostar already has a warped disk

Using observations from the ALMA radio observatory in Chile, researchers have observed, for the first time, a warped disk around an infant protostar that formed just several tens of thousands of years ago. This implies that ...

Complex organic molecules discovered in infant star system

For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disk surrounding a young star, suggesting once again that the conditions that spawned ...

A close call of 0.8 light years

A group of astronomers from the US, Europe, Chile and South Africa have determined that 70,000 years ago a recently discovered dim star is likely to have passed through the solar system's distant cloud of comets, the Oort ...
