Like any telescope, the HST has a long tube that is open at one end to let inlight. It has mirrors to gather and bring the light to a focus where its "eyes" are located. The HST has several types of "eyes" in the form of various instruments. Just as insects can see ultraviolet ...
” provides a good test of the 3K system’s robustness. Only two objects in that special issue were in the planetary kingdom (protoplanets and planetary systems), while 17 were in the stellar kingdom and seven in galaxies. Planetary nebulae dominated the stellar kingdom with 14 objects, and...
cools. While often referred to as a star, a white dwarf is not technically a star as it does not undergonuclear fusion. Rather it is a stellarremnant, likea blackholeora neutron star. Eventually, it is this type of object that will be the sole remains of our Sun billions of years ...
What can we learn from an analysis of a stellar spectrum? Define the dielectric constant. How can the universe be both infinite but expanding? In what specific way does light from distant stars and galaxies tell astronomers that atoms throughout the universe have the same properties as thos...
binary system is predicted to probably become a core-collapse supernova with a small chance of producing a long-duration gamma-ray burst. But even if it does, it might well miss the Earth. So, the chances of a gamma-ray burst directed toward Earth are very, very slim for a long time...
its life in 4 billion years or so. It will swell, turn red (consuming Earth in the process) and cast off its outer layers, giving one last gasp as a planetary nebula before it settles down into post-fusion retirement as a white dwarf. [Supernova Photos: Great Images of Star Explosions...
How much does aperture affect imaging between an 80mm F3.5, 70mm F4 and a 60mm F4.7. Specifically, how much more detail can be seen. Detail comes in different parts: stellar resolution, extended object resolution. Both are determined by aperture, AND seeing. ...
GLIMPSE also has shed light on two of the major structural features of our Milky Way. First, astronomers counted the number of stars at equal angles to the left and right of the galactic center and examined their brightnesses. These GLIMPSE data confirmed the galaxy has a long stellar bar....
