A super-massive black hole is shooting X-rays across galaxies

Over 15 years of observational data collected by NASA’s Chandra X-Ray Observatory and the Australia Telescope Compact Array have given us a composite image of a tremendous cosmic blast. The image depicts an x-ray beam (blue) casts away from the black hole sitting at the center of Pictor A, a galaxy located 500 million light years from Earth. Other prominent […]

The big melt: Antarctica’s retreating ice could re-shape Earth

CAPE LEGOUPIL, ANTARCTICA: From the ground in this extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can’t be seen is the battle raging thousands of feet below to re-shape Earth. Water is eating away at the Antarctic ice, melting it where it hits the oceans. As the ice sheets slowly thaw, water pours […]

A new water world

Saturn’s ice-covered moon Enceladus could harbor a warm-water ocean beneath its frozen surface, opening up new possibilities for life beyond Earth. Enceladus has fascinated astronomers since 2005, when NASA’s Cassini probe caught geysers on the moon’s south pole spewing out plumes of salty water. Water that is thought to have originated in an ocean buried beneath the moon’s 25-mile-thick ice […]

Planet Has More Trees

Planet Has More Trees

The last study showed that the world has about 3 trillion trees.  That is over the estimate of 400 billion in previous studies.  Researchers did a count by actually going out and physically counting trees, using satellite imagery, ground survey, and national forest inventories.  Even though we have lost trees from fires, drought, and insect outbreaks there are still more […]

Effects of climate change on coral reefs and shellfish

Effects of climate change on coral reefs

The newest professor in the University of Rhode Island’s College of the Environment and Life Sciences, Hollie Putnam, thinks some corals and shellfish might have good enough “memories” to buffer the changes in ocean chemistry that are resulting from the effects of climate change on coral reefs. A native of Minnesota who earned a doctorate at the University of Hawaii, […]

Strange Plumes On Mars

  Mysterious plumes of gas rising more than 150 miles above the surface of Mars have left scientists confounded. On two occasions in the spring of 2012, amateur astronomers spotted a cloud developing on the surface of the Red Planet. The plumes, which spanned about 600 miles in diameter and changed shape constantly, appeared within a few hours and remained […]

Humans settled, set fire to Madagascar’s forests 1,000 years ago

There’s no question that our species has had a dramatic impact on the planet’s physical environment, particularly over the last few centuries, with the rise of modern industry, transportation, and infrastructure. But as new research shows, humans have been transforming the landscape, with lasting impacts, since long before the start of the Industrial Era. Scientists from MIT and the University […]
