According to a new study, microbes eat the carbon and release it as CO2, where ends up back in the atmosphere and contributes to further warming.
Instead of pulling galaxies in our universe together, gravity seems to be driving them apart. How can gravity be repulsive, when our everyday experience shows it’s attractive? That’s why we need dark energy …
Why are astronomers excited about the first directly obtained visible light spectrum – or rainbow array of visible colors – bounced from the surface of an exoplanet? Look inside.
Sharks are incredibly unlikely to bite you. They’re even less likely to kill you. However, we remain fascinated with their ability – and occasional proclivity – to do just that.
During the Permian–Triassic mass extinction event 252 million years ago, most life on Earth perished. Scientists have now obtained evidence that ocean acidification played a key role in the die-off.
The shortest lunar month this year happens in between the new moons of April 18 and May 18. This lunar month is only 29 days 9 hours and 16 minutes long, or 3 hours and 28 minutes shorter than the mean lunar month of 29 days 12 hours and 44 minutes.
In April 2015, the moon sweeps to perigee – the moon’s closest point to Earth for the month – on April 17 at 3:53 UTC. That is April 16 at 10:53 p.m. CDT, so it’s possible that – by the time you read this – April’s perigee will have passed. The moon at this perigee is 224,329 miles (361,023 km) from Earth. We list the dates for this year’s 13 lunar apogees (farthest points) and 13 lunar perigees (nearest points), inside.
Yesterday (April 14, 2015), NASA’s New Horizons spacecraft team released this tantalizing first color image of Pluto and its Texas-sized moon Charon. The team called this image a preliminary reconstruction, which they said will be refined later. New Horizons now only three months away from its historic sweep through the Pluto-Charon system in mid-July.
A collection of 10 unexpected and intriguing facts about our solar system – our sun and its family of planets – you probably did not know!
Cassini acquired the false-color image above shortly after astronomers noticed that a huge storm had formed on Saturn, in late December 2010. Saturn is shown in the infrared, viewed through a combination of three filters. The white and blue areas are clouds high in Saturn’s atmosphere. Yellow/green are mid-level clouds. Red/orange are deeper material. See more images inside.
