What is stellar astrophysics? What is the external tank on a space shuttle? What space programs deal with the asteroid belt? Which space shuttle never flew? What was the event that started the space race? What
What is a supernova explosion? What is stellar astrophysics? What is thermonuclear astrophysics? What is theoretical astrophysics? What is the main difference between cosmology and astronomy? What are the odds of a second Big Bang? If so, when will it happen?
Over the following decades, astronomers, aided by the improvements in telescope technology gradually grew the catalogs of stellar distances using the parallax method. In 1924, American astronomer Frank Schlesinger published a catalogue with the parallaxes of almost 2,000 stars, probing stellar distances...
To their shock, they found that the expansion is accelerating as if some bizarre "dark energy" is stretching space. The nature of dark energy is now perhaps the most profound mystery in cosmology and astrophysics. And it may remain forever so.A. Cho...
Question: What is thermonuclear astrophysics? Thermonuclear Astrophysics: The processes that take place within stars and various other astronomical objects are quite complex and involve various chemical and physical-based procedures. All these processes take place at elevated temperatures and lead to the ...
Astrophysics - Solar and Stellar AstrophysicsWhen a planet falls onto the surface of its host star, the added high-metallicity material does not remain in the surface layers, as often assumed, but is diluted into the interior through fingering (thermohaline) convection. Until now, however, the ...
VY Canis Majorishas been most recently measured to be about 1,420 times the width of the sun, in a 2012 paper in the journalSolar and Stellar Astrophysics. This red hypergiant star was once estimated to be 1,800 to 2,200 times the width of the sun, but new measurements brought it dow...
What is an Astronomer? An astronomer studies celestial objects and phenomena in the universe. They explore and investigate various aspects of the cosmos, including stars, planets, galaxies, asteroids, comets, and other celestial bodies. Astronomers seek to understand the nature, composition, behavior,...

Today, this model is known as the Lambda-Cold Dark Matter (LCDM) model, which incorporates current theories about Dark Matter and Dark Energy with the Big Bang theory. In spite of that, the Steady State Hypothesis (and variants thereof) are still advocated by some astrophysicists and cosmologi...
