Latest Planetary science Stories
Dark matter, the hypothetical matter that is cannot be observed using telescopes but is believed to be responsible for huge gravitational effects in the universe, could be indirectly responsible for wiping out the dinosaurs, according to one New York University professor.
Not much escapes the sight of the European Southern Observatory’s Very Large Telescope in Chile, but astronomers using the powerful four-telescope array have been unable to pinpoint the location of a brown dwarf star believed to be orbiting a nearby binary star system.
Exactly 85 years after Clyde Tombaugh’s historic discovery of Pluto, the NASA spacecraft set to encounter the icy dwarf planet this summer is providing its first views of the small moons orbiting Pluto.
On Oct. 8, 2013, an explosion on the sun’s surface sent a supersonic blast wave of solar wind out into space. This shockwave tore past Mercury and Venus, blitzing by the moon before streaming toward Earth. The shockwave struck a massive blow to the Earth’s magnetic field, setting off a magnetized sound pulse around the planet.
Craters and mysterious bright spots are beginning to pop out in the latest images of Ceres from NASA's Dawn spacecraft. These images, taken Feb. 12 at a distance of 52,000 miles (83,000 kilometers) from the dwarf planet, pose intriguing questions for the science team to explore as the spacecraft nears its destination.
One can only assume that NASA is tiring of building orbiters and rovers, because one of their newest projects is a new, unmanned submarine designed to explore the liquid hydrocarbon seas of Titan, the largest moon of Saturn, in a future mission.
New images captured by the Hubble Space Telescope depict a rare event known as a tri-moon conjunction, in which three of Jupiter’s largest moons are passing across the banded face of the gas-giant at the same time, NASA officials announced on Thursday.
Tomorrow night (February 6, 2015), Jupiter, the largest planet in our solar system, will make its closest encounter to Earth until the year 2019 due to its opposition to the Sun, making it visible in the night’s sky. The planet will be located in front of the constellation Cancer, nearby the star Regulus, the brightest star in constellation Leo.
We may not yet be able to assume that intelligent-life exists on other planets, but a team of Australian scientists are confident there are plenty of planets within our galaxy capable of supporting it--hundreds of billions of “Earth-like” planets, in fact.
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...
Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...
Physics of the Earth and Planetary Interiors is a biweekly published peer-reviewed scientific journal published by Elsevier. As of April 2012, co-editors are G. Aelfric (University of Bristol), K. Hirose (Tokyo Institute of Technology), M. Jellinek (University of British Columbia), and K. Zhang (University of Exeter). This journal focuses on the physical and chemical processes of planetary interiors. Topics covered include planetary physics, geodesy and geophysics. Publishing formats...
