solar flare
2014-09-11 03:30:23

Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a significant solar flare, peaking at 1:48 p.m. EDT on Sept. 10, 2014. NASA's Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground.  However -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

Jacqueline Faherty, Carnegie Institution A team of scientists led by Carnegie's Jacqueline Faherty has discovered the first evidence of water ice clouds on an object outside of our own Solar System. Water ice clouds exist on our own gas giant planets--Jupiter, Saturn, Uranus, and Neptune--but have not been seen outside of the planets orbiting our Sun until now. Their findings are published Tuesday, Sept. 9 by The Astrophysical Journal Letters and are available here. At the Las Campanas...

asteroid redirect mission
2014-09-10 07:44:21

NASA Headquarters NASA is on the hunt to add potential candidate target asteroids for the agency's Asteroid Redirect Mission (ARM). The robotic mission will identify, capture and redirect a near-Earth asteroid to a stable orbit around the moon. In the 2020s, astronauts will explore the asteroid and return to Earth with samples. This will test and advance new technologies and spaceflight experience needed to take humans to Mars in the 2030s. NASA has two options for robotic asteroid...

massive star HD100546

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
2014-09-09 07:47:22

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
2014-09-09 04:23:59

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...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. 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...
