I just hit a huge milestone designing my giant pinball machine in Minecraft: the playfield is all laid out!

I'm calling the game Deep Field, and there's five primary objectives based on hitting different shots representing bands of the electromagnetic spectrum.

IR: rollover switches Visible light: pop bumpers UV: captive ball X-rays: Drop targets Gamma rays: spinner

Also, a kinetic sling disc to light locks for Pluto Multiball!

A High Energy Fleet - February 25th, 1996.

"Looking like a fleet of futuristic starcruisers poised over planet Earth, NASA's highly successful series of High Energy Astrophysical Observatory (HEAO) spacecraft appear above in a vintage illustration. Labeled A, B, and C in this conceptual picture, the spacebased telescopes were known as HEAO-1, HEAO-2, and HEAO-3 respectively. HEAO-1 and HEAO-2 were responsible for revealing to earthlings the wonders of the X-ray sky, discovering 1,000s of celestial sources of high-energy radiation. HEAO-2, also known as the Einstein Observatory, was launched near the date of the famous physicist's 100th birthday (November of 1978) and was the first large, fully imaging X-ray telescope in space. HEAO-3, the last in the series, was launched in 1979 and measured high energy cosmic-ray particles and gamma-rays."

CAN WE SEE COLOR IN SPACE??

Blog# 211

Wednesday, July 20th, 2022

Welcome back,

Believe it or not the human eye can see about 7,00,000,000 colors. But, did you know that colors exist that you cannot see? Color does not change in space, because the wavelengths remain the same. Although you can see all the colors of the rainbow, plus every color mixture from those colors, you only have three color detectors in your eyes.  These color detectors, called cones, have a preference for a particular type of light.

Each cone of your eye reads different parts of the light spectrum. The electromagnetic spectrum refers to the entire range and scope of frequencies of electromagnetic radiation and their respective, associated photon wavelengths. Your eyes get excited by the wavelengths and can see the wavelengths for visible light. If you could see infrared, you would see red. If you saw ultraviolet wavelengths you would see violet wavelengths.

The Visible light (and near-infrared light) is typically absorbed and emitted by electrons in molecules and atoms that move from one energy level to another. This action allows the chemical mechanisms that underlie human vision and plant photosynthesis. The light that excites the human visual system is a very small portion of the electromagnetic spectrum.

A rainbow shows the optical (visible) part of the electromagnetic spectrum; infrared (if it could be seen) would be located just beyond the red side of the rainbow with ultraviolet appearing just beyond the violet end.

Every object you see reflects light into your eye. That reflected light reaches our small, medium, and large cone cells located in the eye. Each cell reads a wavelength. The cones send a message to your brain telling it how much long, medium, and short wavelength light bounces off an object. Putting all that into a number code we refer to as color. Although light does not have a color, our brain generates a code when the spectrum of light enters the eye.

During the 1990s NASA launched one of the most complex space telescopes into Earth’s Low Orbit. Low Orbit is the altitude between the Earth’s surface and 2,000 kilometers (1,200 mi). Because it is outside our atmosphere, the telescope can view astronomical objects across a broad swath of the electromagnetic spectrum, from ultraviolet light, to visible, to near-infrared wavelengths. The telescope can also see faint objects near bright objects.

The telescope can resolve astronomical objects with an angular size of 0.05 arc seconds, which is like seeing a pair of fireflies in Tokyo from your home in Maryland. This razor-sharp vision is 10 to 20 times better than typical resolution with large ground-based telescopes.

It has revealed a whole new level of detail and complexity in a variety of celestial phenomena, from nearby stars to galaxies near the limits of the observable universe

When we look at a picture of a Nebula taken with the Hubble telescope we see terrific colors emitting from it. But is that how it really appears in space? No, for the sake of science, scientists color the pictures. 

This famous picture of the Eagle Nebula, named Pillars of Creation, shows fantastic colors surrounding the nebula. Researchers will often add artificial colors to focus on an element or feature they are trying to study. Assigning colors to different wavelengths allows them to learn more about each object. Infrared, microwaves, and radio waves give off deep reds. Ultraviolet, X-Rays, and Gamma-rays give of deep violet colors. While the Hubble telescope can detect wavelengths our eyes cannot see, scientists also color them to keep us interested in space.

“WHY IS SPACE BLACK??”

[whats-in-a-sentence]

Figure 20.3 summarises the wavelengths and frequencies of some regions of the electromagnetic spectrum. (...) The infrared region of the electromagnetic spectrum (figure 20.3) covers the range of wavelengths from 7.8 × 10-⁷ m (just longer than the visible than the visible region) to 2.0 × 10-³ m (just shorter than the microwave region).

Gamma Ray Bursts from the Unknown - August 27th, 1995.

"Gamma Ray Bursts (GRBs) pose one of the greatest mysteries of modern astronomy. About once a day, the gamma-ray sky lights up with a spectacular explosion. No one knows what causes these explosions or even how far away they are. The above map represents the entire sky in coordinates centered on our galaxy, the Milky Way. It shows the positions of over 800 of these mysterious bursts of energy, detected by the BATSE instrument onboard NASA'S Compton Gamma Ray Observatory. Before BATSE, most astronomers thought that most GRBs occurred in the disk of our galaxy, but the above sky map shows little sign of this. The distance scale of GRBs was the topic of a historic debate in April of 1995. The positions in the map above are currently being studied in great detail in an effort to uncover a clue about the nature of GRBs."

The merger of two black holes.

On April 11, 2022, a new observation was published in the journal Physical Review Letters, describing the merger of two black holes which resulted in a violent shift in velocity. After the merger, the more massive single black hole shot off at approximately 5 million miles per hour.

There are two proposed resting places for the newly merged black hole, each with different probabilities.

Understanding how and why it ultimately settles in can help us to create better gravitational models. It can also tell us more about the formation of supermassive black holes like the one that's believed to exist at the center of our own galaxy.
