Sun More Violent Than Believed
2013-12-09 15:03:43

Lee Rannals for redOrbit.com - Your Universe Online NASA's newest solar observatory is showing the region located between the surface of the sun and its atmosphere is more violent than previously thought. The Interface Region Imaging Spectrograph (IRIS) spacecraft launched earlier this summer to study what is known as the interface region. For the past six months, IRIS has given scientists detailed images of this region, finding even more turbulence and complexity than expected. "The...

Image 1 - Paleontologists Discover Oldest Organism With A Skeleton
2012-03-10 05:50:09

Paleontologists have discovered the oldest organism with a skeleton in Australia. The creature is called Coronacollina acula and is estimated to be between 550 and 560 million years old. Paleontologists estimate this animal is from the Ediacaran Period, before the diversification of organisms in the Cambrian Period. The study results appeared online February 14 in Geology. This important find could be the key to unlocking several questions about early life, evolution, and extinction....

A new study sheds light on why the Sun's outer atmosphere, or corona, is more than 20 times hotter than its surface. The research, led by the National Center for Atmospheric Research (NCAR), may bring scientists a step closer to understanding the solar cycle and the Sun's impacts on Earth. The study uses satellite observations to reveal that magnetic oscillations carrying energy from the Sun's surface into its corona are far more vigorous than previously thought. These waves are energetic...

Observations from NASA's Solar Dynamics Observatory (SDO) and the Japanese satellite Hinode show that some gas in the giant, fountain-like jets in the sun's atmosphere known as spicules can reach temperatures of millions of degrees. The finding offers a possible new framework for how the sun's high atmosphere gets so much hotter than the surface of the sun. What makes the high atmosphere, or corona, so hot "“ over a million degrees, compared to the sun surface's 10,000 degrees...

New satellite imagery of the sun is providing scientists with clues to understanding the long-standing mystery of what is heating up the solar corona The 2006 launch of the multinational Hinode satellite changed the picture of the sun for astrophysicists. For two astrophysicists in particular, the resulting imagery offered a voyage of discovery and the thrill of unraveling a long-held solar mystery. The Earth's atmosphere can obscure the view of unaided ground-based telescopes, but,...

Researchers found that fiber optic-like cables allow sea sponges to beam light deep inside their bodies, a discovery that has delighted researchers. German researchers published the findings in the Journal of Experimental Marine Biology and Ecology. Sponges are among the oldest and simplest of Earth's animals. Researchers say sponges appear to be the only animals capable of transmitting light around their bodies in this way. They believe the finding reveals why some sponges are able to...

Venus’ Flower Basket, Euplectella aspergillum
2014-01-05 00:00:00

Venus’ Flower Basket (Euplectella aspergillum) is a species of hexactinellid sponge found in the deep ocean. It is found with a male and female shrimp living inside it, which spend their lives living in just one sponge basket. Because of this, Asian cultures use the dead, dried sponge as a wedding present to signify the symbiotic relationship of the sponge and shrimp. The shrimp that make their home inside the basket reproduce and their offspring escape and find their own sponge to call...

Spongilla lacustris
2014-01-05 00:00:00

Spongilla lacustris is a species of freshwater sponge from the Spongillidae family. It is only found mostly in clear freshwater lakes in North America, Europe and Asia. It is often found growing under rocks or logs, and can sometimes be found in slow-moving streams. This particular species is soft and fragile with whitish to greenish coloration. It has irregularly scattered and barely visible water exit holes. The surface is uneven and covered in rough spicules (spikes). This species...

Clathrina clathrus
2014-01-05 00:00:00

Clathrina clathrus is a species of calcareous sponge belonging to the Clathrinidae family. It is a shallow-water species of the Mediterranean Sea and is also found along the Atlantic coasts of Europe as far north as the British Isles. This sponge is yellowish or white and grows up to 4 inches in diameter. It usually appears cushion-shaped at a distance -- its close relative Clathrina coriacea is appears more flattened. Upon closer inspection, the sponge is actually a tangled mass of tubes....

Chromosphere -- The chromosphere (literally, "color sphere") is a thin layer of the Sun's atmosphere just above the photosphere, roughly 10,000 kilometers deep. The chromosphere is more visually transparent than the photosphere. The most common solar feature within the chromosphere are spicules, long thin fingers of luminous gas which appear like the blades of a huge field of fiery grass growing upwards from the photosphere below. Spicules rise to the top of the chromosphere and then sink...
