A star's early chemistry shapes life-friendly atmospheres

Born in a disc of gas and rubble, planets eventually come together as larger and larger pieces of dust and rock stick together. They may be hundreds of light-years away from us, but astronomers can nevertheless watch these ...

Starlinks are easily detected by radio telescopes

Radio astronomy and satellite communication have a long common history. Advances made in one field have benefitted the other, and our modern era of spacecraft and mobile internet is a product of this partnership. But there ...

A magnetar just woke up after three years of silence

When stars reach the end of their main sequence, they undergo a gravitational collapse, ejecting their outermost layers in a supernova explosion. What remains afterward is a dense, spinning core primarily made up of neutrons ...

Researchers defy the limits of streaming

Given the growing number of users and the widening range of devices, streaming is no longer viable in its current form owing to the substantial amount of power and storage capacity it requires. But researchers at EPFL's Embedded ...

Stacking galactic signals reveals a clearer universe

Very similar to stacking astronomy images to achieve a better picture, researchers from the International Centre for Radio Astronomy Research (ICRAR) are employing new methods which will give us a clearer look at the history ...

ASKAP: 36-dish Australian telescope array opens for business

The Australian Square Kilometer Array Pathfinder (ASKAP) is now standing tall in the outback of Western Australia, and will officially be turned on and open for business on Friday, October 5, 2012 . This large array is made ...

SETI on the SKA

Can the Square Kilometer Array - a network of thousands of radio antennas to be based in South Africa and Australia -- be used to hunt for extraterrestrial signals?

Elliptical galaxies not formed by merging

Using an "intuitive" approach, a SISSA study confirms a recent hypothesis on the formation of galaxies, according to which the larger elliptical galaxies formed in very ancient times through a process of local (in situ) star ...

Are aliens watching old TV shows?

You've probably heard the trope about how aliens have been watching old episodes of "I Love Lucy" and might think these are our "historical documents". How far have our signals reached?
