Donna McKinney, Naval Research Laboratory Dr. John Carr, a scientist at the U.S. Naval Research Laboratory (NRL), is part of an international team that has discovered what they believe is evidence of a planet forming around a star about 335 light years from Earth. This research is published in the August 20th issue of The Astrophysical Journal. Carr and the other research team members set out to study the protoplanetary disk around a star known as HD 100546, and as sometimes happens in...

saturn Shadows and Rings

Preston Dyches, NASA Jet Propulsion Laboratory and Seth Shostak, SETI Institute Compared to the age of the solar system -- about four-and-a-half billion years -- a couple of decades are next to nothing. Some planetary locales change little over many millions of years, so for scientists who study the planets, any object that evolves on such a short interval makes for a tempting target for study. And so it is with the ever-changing rings of Saturn. Case in point: Saturn's narrow, chaotic...

meteorite impact crater in Nicaragua

Chuck Bednar for redOrbit.com - Your Universe Online Nicaraguan officials reported Sunday that the impact of a small meteorite had left a nearly 40-foot crater near the airport of the capital city of Managua, but US scientists are casting doubts on those claims. According to an Associated Press (AP) report published Sunday night, Nicaraguan spokeswoman Rosario Murillo explained that a committee formed by the government to study the incident determined the 16-foot deep crater was caused...

WASHINGTON, Sept. 8, 2014 /PRNewswire-USNewswire/ -- Scientists have found evidence of plate tectonics on Jupiter's moon Europa. This indicates the first sign of this type of surface-shifting geological activity on a world other than Earth. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Researchers have clear visual evidence of Europa's icy crust expanding. However, they could not find areas where the old crust was destroyed to make room for the new. While examining Europa...

plate tectonics on Europa
2014-09-08 12:06:43

NASA/JPL Scientists have found evidence of plate tectonics on Jupiter's moon Europa. This indicates the first sign of this type of surface-shifting geological activity on a world other than Earth. Researchers have clear visual evidence of Europa's icy crust expanding. However, they could not find areas where the old crust was destroyed to make room for the new. While examining Europa images taken by NASA's Galileo orbiter in the early 2000s, planetary geologists Simon Kattenhorn, of the...

Is The Fossil Record Too Incomplete?
2014-09-04 03:17:32

University of Bristol Do all the millions of fossils in museums around the world give a balanced view of the history of life, or is the record too incomplete to be sure? This question was first recognized by Charles Darwin and has worried scientists ever since. Methods have been developed to try to identify and correct for bias in the fossil record but new research from the Universities of Bristol and Bath, suggests many of these correction methods may actually be misleading. The...

NASA A small asteroid, designated 2014 RC, will safely pass very close to Earth on Sunday, Sept. 7, 2014.  At the time of closest approach, based on current calculations to be about 2:18 p.m. EDT (11:18 a.m. PDT / 18:18 UTC), the asteroid will be roughly over New Zealand.  From its reflected brightness, astronomers estimate that the asteroid is about 60 feet (20 meters) in size. Asteroid 2014 RC was initially discovered on the night of August 31 by the Catalina Sky Survey near Tucson,...

Maria-José Viñas, NASA’s Earth Science News Team One of the most visible signs of climate change in recent years was not even visible at all until a few decades ago. The sea ice cap that covers the Arctic Ocean has been changing dramatically, especially in the last 15 years. Its ice is thinner and more vulnerable – and at its summer minimum now covers more than 1 million fewer square miles than in the late 1970s. That’s enough missing ice to cover Alaska, California and Texas....

Titan subsurface reservoirs
2014-09-03 07:03:10

European Space Agency The international Cassini mission has revealed hundreds of lakes and seas spread across the icy surface of Saturn's moon Titan, mostly in its polar regions. These lakes are filled not with water but with hydrocarbons, a form of organic compound that is also found naturally on Earth and includes methane. While most of the liquid in the lakes is thought to be replenished by rainfall from clouds in the moon's atmosphere, the cycling of liquid throughout Titan's crust and...

In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...
