Latest Planetary science Stories
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.
Researchers set out to study the protoplanetary disk around a star known as HD 100546, and as sometimes happens in scientific inquiry, it was by "chance" that they stumbled upon the formation of the planet orbiting this star.
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.
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.
WASHINGTON, Sept. 8, 2014 /PRNewswire-USNewswire/ -- Scientists have found evidence of plate tectonics on Jupiter's moon Europa.
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.
BERLIN and KARLSRUHE, Germany, September 5, 2014 /PRNewswire/ -- Disy Informationssysteme GmbH will present GIS 2go at INTERGEO 2014.
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?
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.
One of the most visible signs of climate change in recent years was not even visible at all until a few decades ago.
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...
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...
