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 ...
interstellar medium, while H II regions are among its gaseous constituents. Planetary nebulae are circumstellar in nature, the result of a dying star ejecting its outer envelope. Globular clusters fall in the stellar systems family, while those nebulosities that are extragalactic go into galaxy sub...
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...
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...
Its hitchhikers, meanwhile, hunker down, recalling the reality of their own evolution — death as they individually experienced it. Windows to the past, the three squatters need an ear to bend and confess: “We have been dead for a long time. We are, what humans would call, relics from ...
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. ...
A red giant star is one step in a star's long lifetime.Günay Mutlu / Getty Images The main sequence doesn't cover the star's entire life. It's just one segment of stellar existence, and in some cases, it's a comparatively short part of the lifetime. Once a star has used up al...
