Charon: The Major Key to Pluto

Up until very recently, Pluto was considered the ninth planet of our solar system. That all changed when the definition of a planet was revised, and Pluto just became another Kuiper belt object albeit the most famous one. We know significantly more about Pluto than any other Kuiper belt object simply because it was discovered … Continue reading “Charon: The Major Key to Pluto” Continue reading Continue reading

The Dwarf Planet Sedna

According to Inuit mythology, Sedna was the name of a mortal woman who became a goddess of the ocean and the underworld.

Planet 9

It was a sad day when the powers that be decided that Pluto was no longer fit to be called a planet. However, this January, in a shocking turn of events, scientists at Caltech may have discovered (or somewhat indirectly presume) the existence of a real ninth planet, an ice giant by the incredibly original […] Continue reading Continue reading

Spectra Across Spectral Types

One of the beautiful aspects of the universe is that not every celestial object is exactly the same. The majority of stars spend their lives on the “main sequence” in which they have stable volume and continuously undergo hydrogen fusion. Astronomers use a classification system based solely upon the temperature of a star, assigning each […] Continue reading Continue reading

I’ve got this giant telescope and I don’t know where to put it: a guide for all your telescope placement needs.

Hey, where should I put my giant telescope? Ideally, you would put your telescope into space! Space is most advantageous for observing the stars because most types of non-visible light are blocked by our atmosphere; this wider spectrum of detectable light allows for more detailed study of some of the universe’s greatest extremes. Some of […] Continue reading Continue reading

In Other News: We Can Analyze Atmospheres of Super-Earths

(Feature Image courtesy of ESA/Hubble, M. Kornmesser) In the past week, the big news in astronomy was the first detection of gravitational waves, a phenomenon predicted by Albert Einstein in his general theory of relativity. No doubt within a few years students will be reading in textbooks about how the LIGO experiment measured the gravitational […] Continue reading Continue reading
