NEBULAE AND BIRTH

Nebulae and Stellar Birth. Overview. Stellar nurseries are made of clouds of dust and gas called nebulae (singular is nebula).All stars are born out of nebulae -- except in some rare instances when two neutron stars merge to form a black hole (however, both neutron stars and black holes are considered to be "dead" stars).. There are two different origins of nebulae. HERTZSPRUNG-RUSSELL DIAGRAM HISTORY It is now called the Hertzsprung-Russell Diagram in honor of these two pioneers.

Mars is about half the size of our planet, Earth.It's thin atmosphere is slowly being blown away by the sun's solar wind.However, its atmosphere forms clouds, and sometimes supports planet-wide dust storms. VENUS - JTG.SJRDESIGN.NET Venus. Overview. When Venus was first studied in modern times, scientists saw a beautiful world that was almost the size of Earth, and it had a thick cover of clouds.The picture to the right shows what Venus looks like when seen in ultra-violet light (UV shows more contrast in the clouds). BINARY AND VARIABLE STARS Binary and Variable Stars. Overview. For a casual observer, binary star systems can often be confused with variable stars, and vice versa. The reason for this is that they both seem to vary their output of light. However, these two phenomenon are in no way related, for binary stars are two stars that are locked in each others'

Overview. For a casual observer, binary star systems can often be confused with variable stars, and vice versa. The reason for this is that they both seem to vary their output of light. However, these two phenomenon are in no way related, for binary stars are two stars that are locked in each others'

COMETS - JTG.SJRDESIGN.NET Comets. Overview and A Bit of History. Comets have been around since the beginning of the solar system, and they have been recorded since written history began.Originally, comets were known as "hairy stars," and were unexplained, unpredictable (although it was thought that they predicted many things), and brought death and destruction. EXPOSING PSEUDOASTRONOMY PODCAST An object with 4x the mass and 23x the diameter would have a surface gravity of 4/23^2 that of Jupiter -- only 0.76% Jupiter's surface gravity. Jupiter's "surface" gravity is roughly 2.4x Earth's, meaning that Planet X's would only be 1.8% Earth's under Nancy's scenario, not 150%. Again -- fairly basic physics. VENUS - JTG.SJRDESIGN.NET Venus. Overview. When Venus was first studied in modern times, scientists saw a beautiful world that was almost the size of Earth, and it had a thick cover of clouds.The picture to the right shows what Venus looks like when seen in ultra-violet light (UV shows more contrast in the clouds).

Parallax is the only direct method that we have to determine distances to objects outside the solar system. It is sometimes abbreviated as π, as in the diagram above.The discovery of the first parallax is an interesting story and is related in short on the page, "Finding Parallax."Parallax is defined as the apparent motion of an object relative to a distant, fixed background when HERTZSPRUNG-RUSSELL DIAGRAM USES Hertzsprung-Russell Diagram Uses.

GREETINGS

I am a research scientist at Southwest Research Institute (SwRI) in Boulder, Colorado, USA. The majority of my past research has been on Martian impact craters, including my doctoral thesis work, though I have expanded into lunar and mercurian craters as well as impact craters strewn across Saturn's moons. Part of my research is as Science Lead on the citizen science project "Moon Mappers " and its sister project, "Mercury Mappers." This is a web portal that shows volunteers from around the world high-resolution imagery of the Moon and asks them identify features such as craters. One of my research philosophies is that if you're going to study something, do it all. To that end, my doctoral dissertation research was based around creating a vast, global database of craters on the planet Mars from which to extract various nuggets of information (more about that on my Mars crater research page ). I am also interested and active in the education and public outreach (EPO) part of astronomy and consider it a fundamental part of what a research scientist should do. My focus in this area is more of a sub-class of normal EPO as I am most interested in combating the bad science that is out there as it relates to astronomy, geology, and/or physics. I have given many interviews, public lectures, and planetarium shows on these kinds of topics, and I also write a blog entitled, "Exposing PseudoAstronomy, " and I run the eponymous podcast. _All EPO work is done independent of my

SwRI employment._

Please use the navigation on the left to find out more about what I do. Note that the Research has several sub-pages to it (and may not work quite right on a smrt phone). ------------------------- * My CV (updated June 12, 2015) . � 2002-2016 Stuart Robbins | Contact Me | Site last updated July 29,
