Astronomers using data from three of NASA's space telescopes -- Hubble, Spitzer and Kepler -- have discovered clear skies and steamy water vapor on a gaseous planet outside our solar system.

exoplanet sun wobble
2014-09-16 04:19:22

New evidence from Cornell University reveals that "hot Jupiters," or large gaseous exoplanets, can cause their host stars to wobble as the planets wend their way through their own solar systems to snuggle up against their suns.

coldest known brown dwarf

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.

massive star HD100546

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.

asteroid impact

An eruption of dust around a young solar-analog star discovered using the Spitzer Space Telescope could be the type of massive collision between asteroids that ultimately result in the formation of planets, astronomers report in Thursday’s online edition of the journal Science.

hunting for exomoons

Scientists hunting for life beyond Earth have discovered more than 1,800 planets outside our solar system, or exoplanets, in recent years, but so far, no one has been able to confirm an exomoon.

Companion planets

For humans, having a companion in our later years can help increase our lifespan. A new study led by the University of Washington shows that having a companion might also extend the life of some Earth-sized planets.

Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report.

gas giant planet HD 209458b
2014-07-24 07:35:40

Astronomers using NASA's Hubble Space Telescope have gone looking for water vapor in the atmospheres of three planets orbiting stars similar to the sun -- and have come up nearly dry.

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...

Planetary and Space Science

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...

Terraforming -- Terraforming (literally, "Earth-shaping") is the process of modifying a planet, moon or other body to a more habitable atmosphere, temperature or ecology. The term was first used in a science fiction novel, 'Seetee Shock' (1940?) by Jack Williamson, but the actual concept is older than that. An example in fiction is 'First and Last Men' by Olaf Stapledon in which Venus is modified, after a long and destructive war with the original inhabitants, who naturally object to the...

Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...

Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...
