In 2019, researchers captured the first image of a black hole. They were able to do this by having all the major radio telescopes on Earth act together to simulate a radio telescope that was the size of Earth. Before this, we could only see indirect evidence of the existence of black holes. This particular […] Continue reading

Pluto: from planet to dwarf planet

Pluto is one of the six dwarf planets that we have currently identified in our solar system, and it was the first object discovered in the Kuiper belt.

Blog 6: Asteroids

On this Tuesday, April 5th, an asteroid the size of a house flew by the Earth. This asteroid flew by 79,000 miles away from us, which is actually pretty close.

Where does the speed of light come from?

It might seem that the definition of the speed of light is simple–light can only physically go as fast as 300,000 km/s. This is true, but there is a lot more that goes into that number, and it doesn’t really have much to do with light. There is a lot more that goes into that […] Continue reading

Kepler Supernova

The image above is of Kepler’s Supernova, which Johannes Kepler is credited with discovering with his description of the stellar object in his De Stella Nova. As stars progress through their main sequence lifetime and beyond and use up more of their hydrogen in nuclear fusion, they can fuse heavier and heavier elements. More massive […] Continue reading

What was Theia?

Theia was about the size of Mars. It orbited with Earth.  It crashed into the Earth and the debris helped create the moon. The core of Theia combined with the core of Earth. Scientists disagree on this and some believe that it formed into multiple moons. It is hypothesized to have orbited in the L4 […] Continue reading

History of our Solar System

Approx. 13.8 billion years ago, everything we know and love in the universe was formed with The Big Bang. Fast-forwarding 9.2 billion years, we can start to see the formation of our Solar System. 4.6 billion years ago, what we call the Solar System was nothing but a large cloud of debris, gas, and dust […] Continue reading

Persevering through the trials of landing on Mars

Space rovers can cost a space program billions of dollars to make; in fact, Perseverance cost NASA 2.7 billion dollars. (Planetary) With that much money, time, and effort being put into a project, it makes sense that those behind it, wish to actually see their hard work successfully operate. For this to happen, the rover […] Continue reading

Halley’s Comet

Halley’s Comet was the first comet understood to be a periodic comet, or a comet that can pass through the solar system multiple times. The English astronomer Edmund Halley (1656-1742) noticed that the previously recorded orbits of three comets were ve… Continue reading
