From terraforming to finding aliens, a geophysicist explains
The Conversation organised a public question-and-answer session on Reddit in which David Waltham, reader in mathematical geology at Royal Holloway in London, explained what makes Earth so special and what lif ...
SDO spots a summer solar flare
The sun emitted a mid-level solar flare, peaking at 12:20 p.m. EDT on July 8, 2014, and NASA's Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation. Harmful ...
Carbon monoxide predicts 'red and dead' future of gas guzzler galaxy
Astronomers have studied the carbon monoxide in a galaxy over 12 billion light years from Earth and discovered that it's running out of gas, quite literally, and headed for a 'red and dead' future.
The Southern Lights put on a display in the night sky
Over the past few months night sky watchers in the southern parts of Australia have been presented with lots of beautiful displays of the Aurora Australis or Southern Lights.
Under the bright lights of an aging sun
Life as we know it on Earth is linked to our star, the Sun, which provides our planet with just the right amount of heat and energy for liquid water to be stable in our lakes, rivers and oceans. However, ...
Comet Pan-STARRS marches across the sky
(Phys.org) —NASA's NEOWISE mission captured a series of pictures of comet C/2012 K1—also known as comet Pan-STARRS—as it swept across our skies in May 2014.
Satellite will help predict climate changes, say Stanford researchers
The Orbiting Carbon Observatory satellite will monitor carbon dioxide concentrations in the atmosphere and help scientists understand the lifecycle of carbon on Earth.
Controversial clues of two 'Goldilocks planets' that might support life are proven false
Mysteries about controversial signals coming from a dwarf star considered to be a prime target in the search for extraterrestrial life now have been solved in research led by scientists at Penn State University. ...
Higher scorer on the easy scale: Gliese 832c and potential habitability
To find a nearby exoplanet similar to Earth is the hope and the challenge. Even for Gliese 832c – a possible super-Earth only 16 light years away – discovering how comparable it is to our home planet is super-tric ...
Meteorite find may be 'missing half' of interstellar collision
Evolution of life's operating system revealed in detail
The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study.
Would Earth look like a habitable planet from afar?
Even when a distant world has the trademarks of habitability—it's Earth-sized, it's in the zone around its star where liquid water is possible—finding signs of life is tricky. The telescope technology ...
Five things about OCO-2
